RE: Well Sampling Results
Groundwater Incident No. 2991
Rowan County
Dear Mr. Samples:
Your well has been sampled periodically as part_of the ongoing groundwater investigation at the
Alchem, Inc. facility. Staff from this office sampled your well again on February 10, 2015.
Enclosed is a copy of the laboratory report for that sampling event. All samples were completed by
the lab on April 23, 2015.
At the time of sampling, the concentrations of dissolved solids, iron and sulfate exceeded the NC
Groundwater Standards for these parameters. As. a result, this office requested an updated Health
Risk Evaluation from the state toxicologist, on April 25, 2015, which was received on July 9, 2015.
Dr. Rudo's recommendation is enclosed.
Below is a summary of the concentrations of parameters of interest/concern for.this most recent
-.sampling event. A second table showing history of past sampling events and trend of
concentrations is included for your convenience on page 2.

Water hardness is calculated from calcium and magnesium concentrations, which is why these
parameters are included in the table above. Increased Hardness, Sulfate and Iron may explain the
water's objectionable taste.

SULFATE

Well Management Section

SULFATE IN WELL WATER
Sulfate (SO4) occurs naturally in most of
Minnesota's groundwater, with higher levels
common in the western part of the state. At
high levels, sulfate can give water a bitter or
astringent taste and can have laxative effects.
This brochure provides a basic discussion of
sulfate in well water and discusses actions
you can take to minimize its effects.
How does sulfate get into
the groundwater?
As water moves through soil and rock
formations that contain sulfate minerals,
some of the sulfate dissolves into the
groundwater. Minerals that contain sulfate
include magnesium sulfate (Epsom salt),
sodium sulfate (Glauber's salt), and calcium
sulfate (gypsum). The level of sulfate in
most groundwater in Minnesota is low, less
than 250 milligrams per liter (mg/L).*
Sulfate occurs at higher levels, which
sometimes can exceed 1000 mg/L, in certain
areas of the state, particularly in the
southwest and along the western boundary.
High levels of sulfate also occur, though less
commonly, in some wells in the northeastern
and southeastern parts of the state.
* One mg/L is one thousandth of a gram in a
liter of water, which is approximately
equal to I part Per million (ppm).
One ppm is approximately equal to
one drop of the;substance in 10 gallons of
water.
Are there health risks for humans
who drink water containing sulfate?
People
unaccustomed to
drinking water with
elevated levels of
sulfate can
experience diarrhea
and dehydration.
Infants are often
more sensitive to
sulfate than adults. As a precaution,
water with a sulfate level exceeding
400 mg/L should not be used in the
preparation of infant formula. Older
children and adults become accustomed to
high sulfate levels after a few days.
Can sulfate harm animals?
Animals are also
sensitive to high
levels of sulfate.
In young animals,
high levels may
be associated
with severe, chronic diarrhea, and in a few
instances, death. As with humans, animals
tend to become accustomed to sulfate over
time. Diluting water high in sulfate with
water low in sulfate can help avoid
problems of diarrhea and dehydration in
young animals and animals not
accustomed to drinking high sulfate
water. The ratio of water high in sulfate to
water low in sulfate can be gradually
increased until the animals can tolerate the
high sulfate water. Contact a veterinarian
or your county office of the Minnesota
Extension Service for more information.
Can sulfate cause other problems?
If sulfate in water exceeds 250 mg/L, a
bitter or medicinal taste may render the
water unpleasant to drink. High sulfate
levels may also corrode plumbing,
particularly copper piping. In areas with
high sulfate levels, plumbing materials
more resistant to corrosion, such as plastic
pipe, are commonly used.
How can sulfate be removed from
water?
Three types of treatment systems will
remove sulfate from drinking water:
reverse osmosis, distillation, or ion
exchange. Water softeners, carbon filters,
and sediment filters do not remove sulfate.
Water softeners merely change magnesium
or calcium sulfate into sodium sulfate,
which is somewhat more laxative.
Reverse osmosis (RO) is a water treatment
system that removes most dissolved
substances, such as sulfate, from water by
forcing the water through a cellophane -like
plastic sheet known asa "semipermeable
membrane." It can typically remove
between 93 and 99 percent of the sulfate in
drinking water depending on the type of
unit. A small counter top RO unit will
produce about 3 gallons per day. Slightly
larger units that are usually installed under
the sink will produce 5 to 20 gallons per
day. RO units typically produce only
1 gallon of water for every 4 to 10 gallons
of water treated. The remaining water goes
to waste.
Distillation is a water treatment system that
boils water, then cools the steam until it
condenses into a separate container. The
dissolved substances, such as sulfate, are left
behind in the boiling pot. With proper
operation, distillation units can remove
nearly 100 percent of sulfate. Distillation
units require about four hours to produce
1 gallon of water, so this type of treatment
uses a considerable amount of energy in its
operation.
Ion Exchange is the most common method
of removing large quantities of sulfate from
water for commercial, livestock, and public
supplies, but is not commonly used for
individual household water treatment. It is a
process where one element or chemical is
switched for another. Many.people are
familiar with water softening, one common
type of ion exchange system. Water
softening works by passing "hard" water -
water with calcium and magnesium -
through a tank filled with a special resin
saturated with sodium ions. The hardness
minerals stick to the resin, and the sodium is
dissolved in the water. Ion exchange
systems for removal of sulfate work in a
similar manner, but use a different type of
resin. Sulfate ions in the water exchange
places with other ions, usually chloride,
which is on the resin. Whdn the resin is full
to capacity with sulfate, it must be
"regenerated" with a salt solution. Water
softeners for removal of hardness do not
remove sulfate, and sulfate removal systems
do not remove hardness, although some
commercial units contain both resins and can
remove both hardness and sulfate.

Should you decide to install a treatment system, the ability to remove Sulfate should also be a
requirement. The enclosed brochure on "Sulfate in Well Water" will provide some information on
water treatment systems.
The hard water and dissolved solids could have an effect on the efficiency and operational life of
your well pump. Please note, that any treatment system you might install will only address issues
after the well and will not prolong the life of your well pump.

RE: Well Sampling Results
Groundwater Incident No. 2991
Rowan County
Dear Ms. Daniels:
Your well has been sampled periodically as part of the ongoing groundwater investigation at the
Alchem, Inc. facility. Staff from this office sampled your well again on February 10, 2015.
Enclosed is a copy of the laboratory report for that sampling event. All samples were completed by
the lab on April 23, 2015.
At the time of sampling, the concentrations of dissolved solids and sulfate exceeded the NC
Groundwater. Standards for these.parameters.: As a result, this office requested an updated Health
----------Risk-Evaluation--from-the-state-toxicologist; onApril-25, 201-5-,-which-was- received- on July-9-2015 -=-
Dr. Rudo's recommendation is enclosed.
Below is a summary of the concentrations. of parameters of interest/concern for this most recent
sampling event. A second table showing history of past sampling events and trend of
concentrations is .included for your convenience on page 2.

Water hardness is calculated from calcium and magnesium concentrations, which is why these
parameters are included in the table above. Increased Hardness, Sulfate and. Iron may contribute
to water "taste" concerns.

Definition
A
Value reported is the mean (average) of two or more determinations. This code is to be used if the results of two or more discrete
and separate samples are averaged. These samples shall have been processed and analyzed independently (e.g., field duplicates,
different dilutions of the same sample). This code is not required for BOD or coliform reporting since averaging multiple
dilutions for these parameters is fundamental to those methods.
B
Results based upon colony counts outside the acceptable range. and should be used with caution. This code applies to
microbiological tests and specifically to membrane filter (MF) colony counts. It is to be used if less than 100% sample was
analyzed and the colony count is generated from a plate in which the number of colonies exceeds the ideal ranges indicated by
the method. These ideal ranges are defined in the method as:
Fecal coliform or Enterococcus bacteria: 20-60 colonies Total coliform bacteria: 20-80 colonies
1. Countable membranes with less than 20 colonies. Reported value is estimated or is a total of the counts on all filters
reported per 100 ml. -- - - -- -
2. Counts from all filters were zero. The value reported is based on the number of colonies per 100 ml that would have
been reported if there had been one colony on the filter representing the largest filtration volume (reported as a less
than "<" value).
3. Countable membranes with more than 60 or 80 colonies. The value reported is calculated using the count from the
smallest volume filtered and reported as a greater than ">" value.
4. Filters have counts of both >60 or 80 and <20. Reported value is estimated or is a total of the counts on all filters
reported.per 100 ml.
5. Too many colonies were present; too numerous to count (TNTC). TNTC is generally defined as >150 colonies. The
numeric value represents the maximum number of counts typically accepted on a filter membrane (60 for fecal or
enterococcus and 80 for total), multiplied by 100 and then divided by the smallest filtration volume analyzed. This
number is reported as a greater than value.
6. Estimated Value. Blank contamination evident.
7. Many non-coliform or non-enterococcus colonies or interfering non-coliform or non=enterococcus growth present. In
this competitive situation, the reported value may under -represent actual density.
Note: A "B" value shall be accompanied by justification for its use denoted by the numbers listed above (e.g., B1, B2, etc.).
Note: A'12" should be used forspiking failures.
BB
This code applies to most probable number (MPN) microbiological tests.
1. No wells or tubes gave a positive reaction. Value based upon the appropriate MPN Index and reported as a less than
"<" value.
2. All wells or tubes gave positive reactions. Value based upon the MPN Index and reported as a greater than ">" value.
Note: A "BB" value shall be accompanied by justification for its use denoted by the numbers listed above e.., BBl, BB2, etc.).
C
Total residual chlorine was present in sample upon receipt in the laboratory; value is estimated. Generally applies to cyanide,
phenol, NA3, TKN, coliform, and organics.
sin a quffify7 control ar ure occurred during biochemical oxygen demand (BUD) analysis. I he sample results should a use
with caution.
1. The dissolved oxygen (DO) depletion of the dilution water blank exceeded 0.2 mg/L.
2. The bacterial seed controls did not meet the requirement of a DO depletion of at least 2.0 mg/L and/or a DO residual of
at least 1.0 mg/L.
3. No sample dilution met the requirement of a DO depletion of at least 2.0 mg/L and/or a DO residual of at least 1.0
mg/L.
4. Evidence of toxicity was present. This is generally characterized by a significant increase in the BOD value as the
sample concentration decreases. The reported value is calculated from the highest dilution representing the maximum
loading potential and should be considered an estimated value.
5. The glucose/ glutamic acid standard exceeded the range of 198 t 30.5 mg/L.
6. The calculated seed correction exceeded the range of 0.6 to 1.0 mg/L.
7. Less than 1 mg/L DO remained for all dilutions set. The reported value is an' estimated greater than value and is
calculated for the dilution using the least amount of sample.
8. Oxygen usage is less than 2 mg/L for all dilutions set. The reported value is an estimated less than value ,and is
calculated for the dilution using the most amount of sample.
9. The DO depletion of the dilution water blank produced a negative value.
Note: A "G" value shall be accompanied by justification for its use denoted by the numbers listed above e.., Gl, G2, etc.).
J
Estimated value; value may not be accurate. This code is to be used in the following instances:
1. Surrogate recovery limits have been exceeded.
2. The reported value failed to meet the established quality control criteria for either precision or accuracy.
3. The sample matrix interfered with the ability to make any accurate determination.
4. The data is questionable because of improper laboratory or field protocols (e.g., composite sample was collected
instead of grab, plastic instead of glass container, etc.).
5. Temperature limits exceeded (samples frozen or >6°C) during transport or not verifiable (e.g., no temperature blank
provided): non -reportable for NPDES compliance monitoring.

J
6. The laboratory analysis was from an unpreserved or improperly chemically preserved sample. The data may not be
accurate.
7. This qualifier is used to identify analyte concentration exceeding the upper calibration range of the analytical
instrument/method. The reported value should be considered estimated.
8. Temperature limits exceeded (samples frozen or >6°C) during storage, the data may not be accurate.
9. The reported value is determined by a one -point estimation rather than against a regression equation. The estimated
concentration is less than the laboratory practical quantitation limit and greater than the laboratory method detection
limit.
10. Unidentified peak; estimated value.
11. The reported value is determined by a one -point estimation rather than against a regression equation. The estimated
concentration is less than the laboratory practical quantitation limit and greater than the instrument noise level. This
code is used when an MDL has not been established for the analyte in question.
12. The calibration verification did not meet the calibration acceptance criterion for field parameters.
Note: A "J" value shall be accompanied by justification for its use denoted by the numbers listed above (e.g., Jl, J2, etc.). A "J"
value shall not be used if another code applies e.., N, V,
M
Sample and duplicate results are "out of control". The sample is non=homogenous (e.g., VOA soil). The reported value is the
lower value of duplicate analyses of a sample.
N
Presumptive evidence of presence of material; estimated value. This code is to be used if:
1. The component has been tentatively identified based on mass spectral library search.
2. There is an indication that the analyte is present, but quality control requirements for confirmation were not met (i.e.,
presence of analyte was not confirmed by alternate procedures).
3. This code shall be used if the level is too low to permit accurate quantification; but the estimated concentration is less
than the laboratory practical quantitation limit and greater than the laboratory method detection limit. This code is not
routinely used for most analyses.
4. This code shall be used if the level is too low to permit accurate quantification, but the estimated concentration is less
than the laboratory practical quantitation limit and greater than the instrument noise level. This code is used when an
JVML has not been established for the analyte in question.
5. The component has been tentatively identified based on a retention time standard.
Holding time exceeded. These codes shall be used if the value is derived from a sample that was received, prepared and/or
analyzed after the approved holding time restrictions for sample preparation and analysis. The value does not meet NPDES
requirements.
1. Holding time exceeded prior to receipt by lab.
2. Holding time exceeded following receipt by lab.
P
Elevated PQL* due to matrix interference and/or sample dilution.
S
Not enough sample provided to prepare and/or analyze a method -required matrix spike (MS) and/or matrix spike duplicate
jJ
Indicates that the analyte was analyzed for but not detected above the reported practical quantitation limit*. The number value
reported with the "U" qualifier is equal to the laboratory's practical quantitation limit*.
X
Sample not analyzed for this constituent. This code is to be used if:
1. Sample not screened for this compound. .
2. Sampled, but analysis lost or not performed -field error.
3. Sampled, but analysis lost or not performed -lab error.
Note: an "X" value shall be accompanied by justification for its use by the numbers listed.
`7
Indicates the analyte was detected in both the sample and the associated method blank. Note: The value in the blank shall not be
subtracted from the associated samples.
Y
Elevated PQL* due to insufficient sample size.
Z
The sample analysis/results are not reported due to:
1. Inability to analyze the sample.
2. Questions concerning data reliability.
The presence or absence of the analyte cannot be verified.
*PQL
The Practical Quarititation Limit (PQL) is defined and proposed as "the lowest level achievable among laboratories within
specified limits during routine laboratory operation". The PQL is about three to five times the calculated Method Detection Limit
(MDL) and represents a practical and routinely achievable detection limit with a relatively good certainty that any reported value
is reliable".

Sulfate in Well Water
Sulfate (SO4) occurs naturally in most of
Minnesota's groundwater, with higher
levels common in the western part of the
state. At high levels, sulfate can give water
a bitter or astringent taste and can have
laxative effects. This brochure provides a
basic discussion of sulfate in well water
and discusses actions you can take to
minimize its effects.
How does sulfate get into
the groundwater?
As water moves through soil and rock
formations that contain sulfate minerals,
some of the sulfate dissolves into the
groundwater. Minerals that contain sulfate
include magnesium sulfate (Epsom salt),
sodium sulfate (Glauber's salt), and
calcium sulfate (gypsum). The level of
sulfate in most groundwater in Minnesota
is low, less than 250 milligrams per liter
(mg/L).* Sulfate occurs at higher levels,
which sometimes can exceed 1000 mg/L,
in certain areas of the state, particularly in
the southwest and along the western
boundary. High levels of sulfate also
occur, though less commonly, in some
wells in the northeastern and southeastern
parts of the state.
*One mg/L is one thousandth of a gram in
a liter of water, which is approximately
equal to 1 part per million (ppm).
One ppm is approximately equal to
one drop of the substance in 10 gallons
of water.
Are there health risks for
humans who drink water
containing sulfate?
People
unaccustomed to
drinking water with
elevated levels of
sulfate can
experience diarrhea
and dehydration.
Infants are often
more sensitive to
sulfate than adults. As a precaution,
water with a sulfate level exceeding
400 mg/L should not be used in the
preparation of infant formula. Older
children and adults become accustomed to
high sulfate levels after a few days.
Can sulfate harm animals?
Animals are
also sensitive
to high levels
of sulfate. In
young
animals, high
levels may be
associated
with severe, chronic diarrhea, and in a few
instances, death. As with humans, animals
tend to become accustomed to sulfate over
time. Diluting water high in sulfate with
water low in sulfate can help avoid
problems of diarrhea and dehydration
in young animals and animals not
accustomed to drinking high sulfate
water. The ratio of water high in sulfate to
water low in sulfate can be gradually
increased until the animals can tolerate the
high sulfate water. Contact a veterinarian
or your county office of the Minnesota
Extension Service for more information.
Can sulfate cause other
problems?
If sulfate in water exceeds 250 mg/L, a
bitter or medicinal taste may render the
water unpleasant to drink. High sulfate
levels may also corrode plumbing,
particularly copper piping. In areas with
high sulfate levels, plumbing materials
more resistant to corrosion, such as plastic
pipe, are commonly used.
How can sulfate be removed
from water?
Three types of treatment systems will
remove sulfate from drinking water:
reverse osmosis, distillation, or ion
exchange. Water softeners, carbon
filters, and sediment filters do not
remove sulfate. Water softeners merely
change magnesium or calcium sulfate into
sodium sulfate, which is somewhat more
laxative.
Reverse osmosis (RO) is a water
treatment system that removes most
dissolved substances, such as sulfate, from
water by forcing the water through a
cellophane -like plastic sheet known as a
"semipermeable membrane." It can
typically remove between 93 and
99 percent of the sulfate in drinking water
depending on the type of unit. A small
counter top RO unit will produce about
3 gallons per day. Slightly larger units that
are usually installed under the sink will
produce 5 to 20 gallons per day. RO units
typically produce only 1 gallon of water
for every 4 to 10 gallons of water treated.
The remaining water goes to waste.
Distillation is a water treatment system
that boils water, then cools the steam until
it condenses into a separate container. The
dissolved substances, such as sulfate, are
left behind in the boiling pot. With proper
operation, distillation units can remove
nearly 100 percent of sulfate. Distillation
units require about four hours to produce
1 gallon of water, so this type of treatment
uses a considerable amount of energy in its
operation.
Ion Exchange is the most common
method of removing large quantities of
sulfate from water for commercial,
livestock, and public supplies, but is not
commonly used for individual household
water treatment. It is a process where one
element or chemical is switched for
another. Many people are familiar with
water softening, one common type of ion
exchange system. Water softening works
by passing "hard" water, water with
calcium and magnesium, through a tank
filled with a special resin saturated with
sodium ions. The hardness minerals stick
to the resin, and the sodium is dissolved in
the water. Ion exchange systems for
removal of sulfate work in a similar
manner, but use a different type of resin.

Sulfate ions in the water exchange places
with other ions, usually chloride, which is
on the resin. When the resin is full to
capacity with sulfate, it must be
"regenerated" with a salt solution. Water
softeners for removal of hardness do not
remove sulfate, and sulfate removal
systems do not remove hardness, although
some commercial units contain both resins
and can remove both hardness and sulfate.
If both a water softener and a sulfate
removal system are used, the water
softener is usually placed before the
sulfate removal system.
Any water treatment system requires
proper operation and maintenance to
ensure that it continues to function
properly. It is important to follow the
recommendations of the manufacturer and
installer for the maintenance of the water
treatment system.

RE: Well Sampling Results
Groundwater Incident No. 2991
Rowan County
Dear Mr. Samples:
August 27, 2012
Your well has been sampled periodically as part of the ongoing groundwater investigation at the Alchem, Inc. facility. Staff from this
office sampled your well again on June 27, 2012. Enclosed is a copy of the laboratory report for t5 it t sampling event. You will note
that there are two sets of analyses for metals. This was done to compare the total and dissolved fractions of metals in your water.
At the time of sampling, the concentrations of dissolved solids, iron and sulphate exceeded the NC Groundwater Standards for these
parameters. As a result, this office requested an updated Health Risk Evaluation from the state toxicologist. Dr. Rudo's
recommendation is enclosed.
Below is a summary of the concentrations of parameters of interest/concern.

mg/L=milligrams per liter wpm = parts per million
The expanded list of parameters that were sampled for this time revealed that your water is very hard. This is the result of high
concentrations of salts such as calcium, magnesium and sulphate. This would explain the water's objectionable taste. In addition, the
water contains a large amount of dissolved solids. In our last conversation, you mentioned that your well pumps have failed
prematurely. The hard water and dissolved solids would likely have an effect on the efficiency and operational life of your pump. I
have enclosed some information on water treatment systems. You may also want to visit www.hardwater.org for additional
information if you decide to purchase a treatment system.

ANALYSIS REPORT
Your well water was tested for 15 metals, plus nitrates, nitrites, and pH. The results were evaluated using the
federal drinking water standards, .The pH is a measure of the acidity of the water. Drinking water may
contain substances that can occur naturally in water or can be introduced into the water from manmade
sources.
TEST RESULTS AND USE RECOMMENDATIONS
Your well water meets federal drinking water standards. Your water can be used for drinking, cooking,
washing, cleaning, bathing, and showering.
/The following substances) exceeded federal drinking water standards. Your water catt be used for
drinking, cooking, washing, cleaning, bathing, and showering, but aesthetic problems such as bad taste, odor,

RE: Well Sampling Results
Groundwater Incident No. 2991
Rowan County
Dear Ms. Beaver:
August 22, 2012
In response to your complaint, staff from this office sampled your well for additional parameters on June 27, 2012. All
the parameters that were measured in the well water were below the established groundwater standards or the laboratory
detection limit (designated with a U after the result). However, the analyses indicate that you have very hard water. Hard
water results from the presence of high amounts of dissolved salts such as calcium, magnesium and sulphate .
Parameter Concentration me/L
Comment
Hardness
330
Average value= 70-135
Calcium

Average value = 20-45
Magnesium
32
Average value = 4.5-5.5
Sulphate
200
Groundwater Standard = 250
Mg/L = milligrams per liter = parts per million
You may want to consider a treatment system for your water supply. I recommend that you inform yourself about hard
water issues prior to purchasing any system. The following website provides good information on hard water and
treatment options: www.hardwater.ori7. The enclosed laboratory report should also prove helpful in selecting an
appropriate treatment method.
Should you have any questions, please call me at 704/235-2183 or contact me via email at: pe.-

Sincerely,

RE: Well Sampling Results
Groundwater Incident No. 2991
Rowan County
Dear Mr. Shirley:
Thank you for your assistance when we sampled your well on June 27, 2012. Enclosed is a copy of the laboratory report for that
sampling event. You will note two .sets of analyses for metals. This was done to compare the total and dissolved concentrations of
metals in your water.
The table below summarizes the key findings:
Constituent
Concentration ppin
Groundwater Standard (limit) ppm
Sulphate
340
250
Total Dissolved Solids
682
500
Hardness
470
indicates very hard water
ppm = parts per million
The concentration of sulphate has increased slightly elevated above the value but is only a small change from the previous results. The
state toxicologist has previously determined that, based on the data, your water is safe to drink. The analysis does indicate that your
water is very hard. Except for sulfate and dissolved solids, all the parameters for which there is a limit were below the groundwater
standards or the laboratory detection limit (designated with Ujafter the result).
Should you have any questions, please call me at 704/2.35-2183 or contact me via email at: pega .fy mley@ncdenr. ov.
Sincerely,
Peggy Finley
Environmental Specialist

RE: Water Supply Well Sampling
Mitchell Residence
Rowan County, N.C.
Dear Ms. Mitchell:
August 20, 2012
The staff of the Aquifer Protection Section sampled your well again on June 27, 2012. Enclosed you will find the
laboratory results for the samples that were collected. You will note that there are results for two sets of metals analyses.
This was done to compare the total and dissolved concentrations of those metals.
The results indicate that, at the time of sampling, the concentrations of those parameters for which there are standards
established were below the limits. The appearance of a U after the number in the Result column indicates that the
parameter was not present above the stated laboratory detection limit. The results of this sampling event were similar to
the findings of the previous sampling.
Should you have any questions, please call me at 704/235-2183 or contact me via email at: peggy.finleyDa iiedenr.Qov
Sincerely,
C7.1

RE: Well Sampling Results
Groundwater Incident No. 2991
Rowan County
Dear Ms. Daniels:
Your well has been sampled periodically as part of the ongoing groundwater investigation at the Alchem, Inc.
facility. Staff from this office sampled your well again on June 28, 2012. Enclosed is a copy of the laboratory
report for that sampling event. You will note that the report contains two sets of analyses for metals. Samples
were collected for both total and dissolved metals for purposes of comparison.
At the time of sampling, all the parameters that were measured were below the groundwater standards or the
laboratory detection limit. Should you have any questions, please call me at 704/235-2183 or contact me via
email at: Peggy.finleyCa)ncdenr.gov.
Sincerely,
Peggy Finley CC//

RE: Water Supply Well Sampling Results
Rowan County, N.C.
Dear Resident:
Your well was sampled on June 27, 2012 as part of an ongoing groundwater investigation. The samples were analyzed
for several constituents. Enclosed you will find the laboratory results. You will note that two sets of analyses were run for
metals in order to compare total and dissolved fractions in the water. Below is a summary of the results for one constituent
of interest.

mg/liter = milligrams per liter = parts per million
U = not present above the stated laboratory detection limit
At the time of the recent sampling, only sulphate exceeded the referenced groundwater standard. According to the state
toxicologist, this amount of sulphate present does not pose a health risk (see enclosed health risk assessment) but may
give the water a salty taste.
Should you have any questions, please call me at 704/235-2183.

Subject: RE: Another Alchem Spill - Contamination to the Aquifer
Attachments: Ted L Bush Jr Chief.vcf
Mr. Cantrell,
In response to your comments this week to Ms. Peggy Finley of my staff, I assure you that my
decision to not intervene in the investigation by our Mooresville -Regional Office staff has
more to do with my confidence in their ability to thoroughly perform an investigation, 'and
less to do with your assertion that I am not "much interested in this matter". I
communicated with Ms. Finley on yesterday prior to her site visit, and have heard from her
via e-mail as well as telephone since. At this point, I have no reason to presume that
everything reasonable has not been done. If you have additional specifics that would assist
us in the investigation, we will be glad to follow up as appropriate. However, in the
absenceof new information, I'm afraid there will be limits to the depth of our
investigation.
During the past -year, our staff has sampled approximately a dozen offsite wells near the
Alchem facility. Your well was sampled on June 16th of this year, and no parameters exceeded
the groundwater standards. For the wells that showed signs of contamination (exceeded the
standard), a health risk assessment by the State Toxicologist,was requested. Thus far the
toxicologist has indicated the water should be safe for household use. We have done
additional sampling in the area, and once results are received, appropriate evaluations by
the.State Toxicologist will be requested.
Although I am unaware of any need for intervention, I will be glad to discuss your concerns
with you. If you would like to reach me, I can be reached in my Raleigh office at (919) 715-
6172. If you would feel more comfortable speaking with my supervisor, his name is Charles
Wakild, and he can be reached at [phone] or the e-mail address indicated in the copy
to this message.
Please let us know if"we can be of further assistance.

That is not what Penny told me? Please send me a copy of the letter. Along with that please
provide me with the supervisor of Ted Bush, he needs to be aware of these issues. I know you
visited Alchem regarding the recent spill which was denied, but would't anyone lie about a
spill?'To cover their negligence? Ted Bush has not responded or replied to any of our
communications which makes me think he isn't much interested in this matter.
I need a copy of the current plan of action for Alchem and where they stand on compliance.
Life is worth much more than money; Alchem is in this for profit, I am in this for the Health
of my community and family. Again my anonymous contributor says there WAS a spill and the
lagoons ARE NOT lined to protocol.

Dear Ms. Daniels:
Dee Freeman
Secretary
Your well has been sampled periodically as part of the ongoing groundwater investigation at the Alchem, Inc.
facility. Alchem's consultants sample your well in February, June and October to measure pH and sulfate.
Staff from this office also sampled your well on April 26,2011for additional constituents. Enclosed is a copy of
the laboratory report for that sampling event. Except for sulfate, all the parameters that were measured were
below the groundwater standards or the laboratory detection limit.
A summary of pH and sufate concentrations are as follows:

The Division's toxicologist has previously stated that the water is safe for.generall household use, including
drinking, but that it may pose aesthetic problems (taste, odor, etc). Should you have any questions, please call
me at 704/235-2183 or contact me via email at: peggy.finleyt'a7ncdenr.qov.

Dear Ms. Beaver:
Dee Freeman

May 31, 2011
Your well has been sampled periodically as part of the ongoing groundwater investigation at the Alchem, Inc.
facility. Alchem's consultants sample your well in February, June and October to measure pH and sulfate. In
response to your complaint, staff from this office sampled your well and kitchen tap for additional parameters
on April 26, 2011. All the parameters that were measured in the well water were below the groundwater
standards or the laboratory detection limit, Based on the reported hardness value of 350 mg/L, your water
would be considered very hard.
Below is a summary of the pH and sufate concentrations that have been measured in your well.

Aluminum at this concentration can create taste and odor problems in water. My review of available
information suggests that the sacrificial anode in your water heater may be the source of your complaint since
some anodes contain aluminum and zinc.
Enclosed are copies of the laboratory reports for our sampling event. Should you have any questions, please
call me at 704/235-2183 or contact me via email at: peggy.finley�'@ncdanr.gov.

RE: Well Sampling Results
Groundwater Incident No. 2991
Rowan County
Dee Freeman
Secretary
May 31, 2011
Your well has been sampled periodically as part of the ongoing groundwater investigation at the Alchem, Inc.
facility. Alchem's consultants sample your well in February, June and October to measure pH and sulfate. In
response to your complaint, staff from this office sampled your well and kitchen tap for additional parameters
on April 26, 2011. All the parameters that were measured in the well water were below the groundwater
standards or the laboratory detection limit. Based on the reported hardness value of 350 mg/L, your water
would be considered very hard.
Below is a summary of the pH and sufate concentrations that have been measured in your well.

Aluminum at this concentration can create taste and odor problems in water. My review of available
information suggests that the sacrificial anode in your water heater may be the source of your complaint since
some anodes contain aluminum and zinc.
Enclosed are copies of the laboratory reports for our sampling event. Should you have any questions, please

RE: Water Well Sampling
Dear Mr. & Mrs. O'Neill:
The Aquifer Protection Section is conducting an investigation of the groundwater in your area. We
would like to collect a water sample from your well to be sure that is not affected. There will be no
cost to you. It is not necessary for you to be home as long as the spigot on your well is accessible.
We plan to conduct the sampling the week of August 22. It will take several weeks for us to get the
results from our laboratory. We will forward the results to you when we receive them.
If you do not wish for us to sample your well or if you have any questions, please call me at 704/
235-2183.
Sincerely,
Pey Finley

RE: Water Well Sampling
The Aquifer Protection Section is conducting an investigation of the groundwater in your area. We
would like to collect a water sample frorn your well to be sure that is not affected. There will be no
cost to you. It is not necessary for you to be home as long as the spigot on your well is accessible.
We plan to conduct the sampling the week of August 22. It will take several weeks for us to get the
results from our laboratory. We will forward the results to you when we receive them.
If you do not wish for us to sample your well or if you have any questions, please call me at 704/
235-2183.
Sincerely,

My husband spoke with a neighbor this morning who had walked over to the plant thru the woods
and someone met him on a 4wheeler asking him to leave the property. Our neighbor told the guy
that he just wanted to see what were in the huge holes behind their company and the man told
him not to touch what was in the hole but he was not at liberty to talk to him about what it was.
Our neighbor then said he was just concerned about what they were putting in the ground and
how that was affecting our water and the man obviously wouldn't discuss that with him. Who
would I contact to go out and check their company now? Surely there is some code they are
breaking by putting that stuff in the ground and surely someone could bust them on that and
put a stop to it. Is that you that I would let know? I just have no clue who my contacts are for
all of this mess and I would really like their company to comply with what needs to be done to
make things safer. Thanks for all your help. I really appreciate it!

RE: Water Supply Well Sample Results
McIntyre Well, 325-345 Large Ave., Rockwell
Rowan County .
Dear Ms. McIntyre:
On December 6, 2007, Division of Water Quality staff sampled the water supply well at 321-335 Large
Ave. in Rockwell that serves several mobile homes. The water samples were analyzed for inorganics, sulfate
and chloride. Inorganic analysis includes a variety of elemental metals such as iron, lead and others, that can
be both naturally occurring or the result of human activities.
A copy of the laboratory results from the samples is enclosed and summarized on the following table.
The table also presents the North Carolina Groundwater Quality and EPA Drinking Water standards for
reference.

The results of the sampling were forwarded to the State Toxicologist, Dr. Ken Rudo, who performed a
Health Risk Evaluation based on human consumption of the water. Dr Rudo's evaluation form is also enclosed
and he has indicated, based on these results, that the water should not be used for drinking or cooking.
He has also advised consideration of an appropriate filtration system to remove the chemicals.
We are currently in the process of evaluating the potential. 'sources of sulfate and other contaminants
that have been detected in groundwater from the area. It appears likely that your well has been impacted by
one of these sources, which we are working to address. Please contact me regarding these results and the
possible implications of these detections of contaminants.
Should you have any questions regarding the health risk evaluation, you may contact Dr. Rudo at (919)
707-5911. If you have other questions, feel free to contact me at [phone] or by email at

RE: Water Supply Well Sample Results
Samples Well, 8470 Medium Drive, Rockwell
Rowan County
On December 6, 2007, Division of Water Quality staff resampled your water supply well. The water
samples were analyzed for inorganics, sulfate and chloride. Inorganic analysis includes a variety of elemental
metals such as iron, lead and others, that can be both naturally occurring or the result of human activities.
A copy of the laboratory results from the samples is enclosed and summarized on the following table.
The table also presents the North Carolina Groundwater Quality and EPA Drinking Water standards for
reference.

*µg/L is equivalent to parts per billion; mg/L is equivalent to parts per million. **EPA Primary or Secondary Drinking Water Standard.
***"Non detect < 5.0" indicates that the analyte was not detected at the laboratory detection limit of 5.0 jig/L.
As illustrated in the table, the concentration of most substances is either non detect or very low. However, the
concentration of sulfate exceeds the referenced standards. We are currently evaluating the potential sources
of sulfate and other contaminants that have been detected in groundwater from the area.

January 18, 2008
The results of the sampling were forwarded to the State Toxicologist, Dr. Ken Rudo, who performed a
Health Risk Evaluation based on human consumption of the water. Dr Rudo's evaluation form is also enclosed
and he has indicated that the water is considered safe for use, though the elevated sulfate may pose aesthetic
(taste, odor, etc.) problems.
Should you have any questions regarding the health risk evaluation, you may contact Dr. Rudo at (919)
707-5911. If you have other questions, feel free to contact me at [phone] or by email at
andrew. itner ncmail.net with any questions.

RE: Water Supply Well Sample Results
Bradshaw Well, 290 Large Ave., Rockwell
Rowan County
Dear Mr. Bradshaw:
On December 6, 2007, Division of Water Quality staff sampled the water supply well at 290 Large Ave.
in Rockwell that serves multiple residences. The samples were analyzed for inorganics, sulfate and chloride.
Inorganic analysis includes a variety of elemental metals such as iron, lead and others, that can be both
naturally occurring or the result of human activities.
A copy of the laboratory results from this sample is enclosed and summarized on the following table.
The table also presents the North Carolina Groundwater Quality and EPA Drinking Water standards for
reference.

On December 6, 2007, Division of Water Quality staff sampled your water supply well. The samples
were analyzed for inorganics, sulfate and chloride. Inorganic analysis includes a variety of elemental metals
such as iron, lead and others, that can be both naturally occurring or the result of human activities.
A copy of the laboratory results from this sample is enclosed and summarized on the following table.
The table also presents the North Carolina Groundwater Quality and EPA Drinking Water standards for

671 Based on these analytical results, the water from your well is considered safe for drinking, cooking,
washing dishes, bathing, and showering.
❑ Chemical concentrations found in your well water are higher than what is recommended. Your
water should not be used for drinking or cooking. These chemicals can be absorbed through the
skin so limit showering and bathing time to under minutes.
Cl Your well water is highly contaminatedand should not. be used for drinking, cooking, bathing, and
showering.
❑ The laboratory result's indicate that follow-up testing is needed; please resample immediately.
PLEASE INDICATE ON FUTURE LAB SHEETS THAT IT IS A RESAMPLE AND PROVIDE
PREVIOUS SAMPLE NUMBER(S).
I/ COMMENTS:
Your laboratory results have been compared to the North Carolina Public Health Goals_(NCPHGs)_
The goals were developed_ by the NC OEEB as non -regulatory concentrations that can be used to
evaluate the safety of private well drinking water. The goals are health -based concentrations that -
are considered safe based _on_.agerson drinking one to two liters of well water a day,
For further information, contact Dr Ken Rudo with the Occupational and Environmental Epidemiology
Branch at [phone].

Il Based on these analytical results, the water from your well is considered safe for drinking, cooking,'
washing dishes, bathing, and showering.
❑ Chemical concentrations found in your well water are higher than what is recommended, Your
water should not be used for drinking or cooking. These chemicals can be absorbed through the
skin so iirnit showering and bathing time to under _ minutes.
❑ Your well water is highly contaminated and should not be used for drinking, cooking, bathing, and
showering.
r,'] The laboratory results indicate that follow-up testing is needed, please resample immediately,
PLEASE INDICATE ON FUTURE LAB SHEETS THAT iT IS A RESAMPLE AND PROVIDE
PREVIOUS SAMPLE NUMBER(S).
l COMMENTS:
Your laboratory results have been compared to the North Carolina Public Health Goals (NCPHGs),
The goals were developed by the NC DEER as non -regulatory concentrations that can be used to
- - evaluate the safety of private well drinking water. -The goals are heeilh-based concentrations that —
are considered safe based on a person drinking one to two liters of wall water a day.

Executive Summary
In the 1996 amendments to the Safe Drinking Water Act, Congress mandated that the
U.S. Environmental Protection Agency (EPA) determine, by August 2001, whether to
regulate sulfate in drinking water. If EPA decides to regulate sulfate, the agency must
propose the Maximum Contaminant Level (MCL) by August 2003 and issue a final standard
by February 2005. Congress also directed EPA to conduct a study with the Centers for
Disease Control and Prevention (CDC) to establish a reliable dose -response relationship for
health effects from exposure to sulfate and to examine effects in sensitive subpopulations
(infants and transients). The directive indicated that the study must "be based on the best
available, peer -reviewed science and supporting studies conducted in accordance with sound
and objective scientific practices," "be conducted in consultation with interested States," and
be completed by February 1999.
CDC researchers had to cancel a planned community -based study of the frequency of
diarrhea in infants exposed to varying levels of sulfate naturally occurring in drinking water
because they could not identify a sufficiently large group of exposed infants. CDC did not
find an association between exposure to sulfate in drinking water and diarrhea in adult
volunteers. As a supplement to their studies and literature review, CDC and EPA organized a
workshop to review CDC's sulfate studies and discuss the most relevant scientific literature
examining the health effects from exposure to sulfate in drinking water.
The workshop began with presentations. Dr. Charles Abernathy, from the EPA Office
of Water, presented the results of selected studies on the health effects of sulfate, a regulatory
history of sulfate, a time line of the actions EPA, has taken on sulfate, and an estimate of the
types and numbers of drinking water systems that would be affected by the regulation of
sulfate in drinking water.
There were three presentations describing the biochemistry and physiology of sulfate
absorption and excretion. Dr. David Cole, of the University of Toronto, presented
information on the importance of sulfate as a component of membranes and many compounds
in humans, the medical effects of sulfate deficiency, and how membrane transport and.
regulation contribute to sulfate homeostasis. Dr. Marie Cassidy, of George Washington
University, presented information on intestinal physiology, including osmotic and bacterial
diarrhea, and reasons why elderly people may be susceptible to diarrhea. Dr. Marilyn Morris,
of the State University of New York (SUNY)-Buffalo, discussed the transport mechanisms
used in the body to regulate inorganic sulfate levels and the relative importance of the
different mechanisms at different developmental stages. Dr. Guillermo Gomez, of North
Carolina State University, presented a study on the gastrointestinal effects of sulfate in
drinking water, using neonatal pigs as an animal model for human infants.
Dr. Lorraine Backer, of the National Center for Environmental Health at CDC,
presented the results of recent studies conducted by CDC of the human health effects in
Page 4

sensitive subpopulations (infants and transients) of exposure to sulfate in drinking water. The
planned study of health effects in infants from exposure to sulfate in drinking water was not
completed because very few mothers of newborns in the areas where there were high levels of
sulfate in the drinking water provided by public water systems gave or were planning to give
infant formula mixed with tap water to their babies. The study of transients involved
analyzing the frequency of self -reported diarrhea in adults exposed to varying levels of sulfate
in drinking water provided to them. In the adult study, there was no statistically significant
association between the concentration of sulfate in the drinking water and the frequency of
diarrhea. Esteban et al. (1997) found no significant association between sulfate intake and
diarrhea in infants in South Dakota.
After the presentations, Dr. Carl Shy of the University of North Carolina lead the
workshop participants in a discussion of four issues:
Issue 1 Do reported studies suggest that a certain sulfate level would not be likely to
cause adverse effects (e.g., diarrhea in infants and travelers)?
Existing data do not identify the level of sulfate in drinking water that would
be unlikely to cause adverse human health effects. The panel members noted
that the available published literature included reports that piglets in
experimental feeding trials and some people experience a laxative effect when
consuming tap water containing from 1,000 to 1,200 mg/L of sulfate (as
sodium sulfate). However, none of the studies found an increase in diarrhea,
dehydration, or weight loss.
Issue 2 Does the literature support acclimatization or adaptation (what process and
time frame does it take)?
Based on biologic plausibility and anecdotal reports, evidence indicates that
people acclimate to the presence of sulfate in drinking water. In addition,
serum sulfate levels are high (compared to adults) in human fetuses and
neonates (to support rapid growth and development). However, data
describing acclimation and the changes in sulfate metabolism during growth
and development are limited.
Issue 3 Can an infant study be done for dose -response anywhere in the U.S. or
Canada?
The difficulty of locating a population of women feeding their infants formula
.mixed with unfiltered tap water containing high levels of sulfate hinders the
completion of a dose -response study in infants. A study using neonatal pigs
could assess a dose response for both magnesium and sodium sulfates.
Page 5

Issue 4 Is there enough scientific evidence that there are adverse health effects from
sulfate in drinking water to support regulation? [Congress directed EPA to use
the best available science to set drinking water goals and regulations.]
There is not enough scientific evidence on which to base a regulation, but
panelists favored a health advisory in places where drinking water has sulfate
levels of >_ 500 mg/L.

Introduction
In the 1996 amendments to the Safe Drinking Water Act, Congress mandated that the
U.S. Environmental Protection Agency (EPA) determine by August 2001 whether to regulate
sulfate levels in drinking water. If EPA decides to regulate sulfate, the agency must propose
the Maximum Contaminant Level (MCL) by August 2003 and issue a final standard by
February 2005. Congress also directed EPA to conduct a study with the Centers for Disease
Control and Prevention (CDC) to establish a reliable dose -response relationship for sulfate
and examine effects in sensitive subpopulations (infants and transients). The directive
indicated that the study must "be based on the best available, peer -reviewed science and
supporting studies conducted in accordance with sound and objective scientific practices," "be
conducted in consultation with interested States," and be completed by February 1999.
CDC researchers had to cancel a planned community -based study of the frequency of
diarrhea in infants exposed to varying levels of sulfate in drinking water because they could
not identify a sufficiently large group of exposed infants. A study of adults exposed to varying
levels of sulfate in drinking water provided to them did not find an association between
exposure to sulfate and the frequency of self -reported diarrhea. Because these studies were
not able to establish a dose -response or a level of sulfate in drinking water that would not be
expected to cause adverse human health effects, CDC and EPA organized a workshop of
scientific experts to present and discuss the most relevant scientific studies conducted on the
health effects of sulfate.
Prior to the workshop, the panel members received a document reviewing the relevant
scientific literature on the health effects of sulfate. At the workshop, each panelist presented
the most current information in his or her field of expertise. The panelists and other workshop
participants discussed the information presented in the literature review and presentations,
focusing on the four key issues listed below:
Issue I Do the studies suggest that a certain contaminant level would not be likely to
cause adverse effects (e.g., diarrhea in infants and travelers)?
Issue 2 Does the literature support acclimatization or resistance (what process and
time frame does it take)?
Issue 3 Can an infant study be done for dose -response anywhere in the U.S. or
Canada?
Issue 4 Is there enough scientific evidence that there are adverse health effects from
sulfate in drinking water to warrant regulation? [Congress directed EPA to
use the best available science to set drinking water goals and standards.]

EPA's Scientific Work and Regulatory Background
Charles Abernathy, Ph.D., Toxicologist
Office of Water, U.S Environmental Protection Agency
Sulfur has many roles in the human body (e.g., as a part of amino acids). Some
sulfates have been employed as medicines in both human and veterinary medicine. For
example, the sodium and magnesium salts of sulfate have been employed as laxatives and the
zinc salt has been used as an emetic. The water solubility of these sulfate salts probably
contributes to the laxative and emetic effects, because the barium and calcium salts are less
soluble and generally not effective. The sulfate salts are not usually employed as laxatives or
emetics, but MgSO4 (magnesium sulfate, or Epsom salt) is still used as a cathartic.
As mentioned above, sulfate is a natural and necessary constituent in the bodies of
humans and other animals. In humans, serum sulfate levels range from 0.25 to 0.38 mmol/L.
Sulfate is involved in a number of biochemical activities including the production of
chondroitin sulfate and sulfation of exogenous chemicals.
Animal toxicity studies have found acute LD50s of MgSO4 to be 6 g/kg (oral exposure)
and 1.2 g/kg (intravenous exposure). There are few data on the chronic effects of exposure
to high doses of this substance. Since its potential for carcinogenicity at high doses has not
been studied, sulfate would be classified as a Group D carcinogen under EPA's 1996
proposed guidelines (i.e., sulfate would be placed in the "carcinogenicity cannot be
determined" group).
There have been a number of studies conducted to determine the toxicity of sulfate in
humans. Chien et al. (1968) presented case reports of diarrhea in three infants exposed to
water containing sulfate (ranging from 630 to 1,150 mg/L). However, there were other
potential causes of the diarrhea in these infants (i.e., consuming infant formula with high
osmolarity or the presence of microbial pathogens) that were not thoroughly addressed by the
investigators. A survey conducted in North Dakota found a slight increase in the percentage
of people (28%) who reported that their drinking water had a laxative effect when the
drinking water contained 500 to 1,000 mg/L sulfate compared to the percentage of people
(21%) who reported a laxative effect from drinking water that contained <500 mg/L. Sixty-
eight percent of people who consumed water with 1,000 to 1,500 mg/L reported a laxative
effect. Peterson (1951) analyzed the data from North Dakota and concluded that drinking
water containing >_ 750 mg/L sulfate was associated with a self -reported laxative effect
whereas drinking water containing < 600 mg/L was not. Moore (1952) reanalyzed the data
reported by Peterson and found that most people experienced a laxative effect when they
drank water that contained >1,000 mg/L sulfate. In 1977, the National Academy of Science
(NAS) reported no ill effects in people who ingested water containing < 500 mg/L sulfate.
Children, transients, and the elderly are the sensitive sub -populations of interest to
EPA because of the potentially high risk of dehydration from diarrhea that might be caused by
high levels of sulfate in drinking water.
In the 1970 Community Water Supply Study, the U.S. Public Health Service (USPHS)
Page 9

measured the sulfate levels in the drinking water sources of nine geographic areas. Sulfate
was present in 645 of 658 groundwater supplies and in all 106 surface water supplies sampled.
Sulfate levels ranged from <1 to 770 mg/L (with a median of 4.6 mg/L). Only three percent
of the water supplies sampled had sulfate levels greater than 250 mg/L.
The Safe Drinking Water Act (SDWA) of 1974 amended the Public Health Service
Act and specified that EPA set primary ( based on health effects) and secondary (based on
aesthetic and organoleptic qualities) drinking water standards.
In a 1975 survey of 625 Interstate Carrier Water Supply Systems, 3.4 percent of the
systems had sulfate levels >250 mg/L. The maximum sulfate level found was 978 mg/L. In a
survey of Rural. Water Supply in the late 1970s, sulfate was found in groundwater at levels
from 10 to 1,000 mg/L, (mean = 98 mg/L), and in surface water at levels from 15 to 321
mg/L (mean = 53 mg/L).
Dr. Abernathy presented the following time line of EPA actions regarding sulfate in
drinking water:
March 31, 1977 EPA proposed the Secondary Maximum Contaminant Level
SMCL of 250 mg/L based on taste (the World Health
Organization (WHO) guideline for sulfate is 400 mg/L, based
on taste; people's threshold for tasting sulfate ranges from 250-
350 mg/L). The Secondary MCL serves as a guideline, not a
federally enforceable standard.
July 19, 1979 The final 250 mg/L sulfate Secondary MCL was
published and became effective January 19, 1981.
November 13,1985 EPA proposed a Health Advisory (HA) for sulfate (400 mg/L)
to protect infants. As data became available, EPA would
reconsider the need for an enforceable standard to protect
transients.
1989 A citizen suit was filed against EPA that led to a consent order
establishing a deadline for the publication of an MCL for
sulfate.
June 25,1990 EPA proposed an enforceable MCL of 400/500 mg/L for
sulfate to protect infants. (the Canadian guideline [not
regulation] is, 500 mg/L). EPA retained the Secondary MCL of
250 mg/L.
Page 10

December 20, 1994 EPA proposed an MCL and health effects goal (maximum
contaminant level goal [MCLG]) of 500 mg/L, as agreed under
the consent order.
The 1996 Amendments to the SDWA established the following deadlines:
February 1999 CDC and EPA must provide a report of jointly conducted
studies to establish a reliable dose -response relationship for
sulfate, including sensitive sub -populations (i.e., infants and
transients).
August 2001 EPA must determine whether or not to regulate sulfate.
February 2005 If the determination is to regulate, EPA must propose the MCL
by August 2003 and issue a final rule by February 2005.
In 1994 EPA estimated that approximately 2,000 of the 54,000 public water systems
in the U.S. would have sulfate levels higher than 500 mg/L. These systems include 1,241
serving 25-100 people, 493 serving 101-500 people, 194 serving 501 to 3300 people, 27
serving 3301 to 10,000 people, 10 serving 10,000 to 100,000 people, and none serving over
100,000 people. [Although public water systems serve 249 million people, 95% of the
systems serve less than 10, 000 people].
Discussion
Dr. David Cole asked if pure sulfate solutions have an odor. Dr. Abernathy responded
that taste is more evident than odor, but that there is some odor. Dr. Marie Cassidy asked Dr.
Abernathy if EPA's mandate is only for sulfate. Dr. Abernathy said that sulfate is one of
several substances that EPA is in the process of determining whether or not to regulate. Buck
Grissom, ATSDR, asked if pH affected sulfate in water. Dr. Abernathy answered that he was
not aware of any effect that pH has on water and sulfate.

Sulfate (S042-) is a divalent anion. There may be up to one percent sulfate present in
gastric fluids. The human body distinguishes sulfate ( 5.7 angstroms) from phosphate (6
angstroms) and thiosulfate (52032-) by the distinctive stereospecific molecular configurations
of each ion. The body maintains a homeostasis between absorbed inorganic sulfate, sulfate
compounds, and renal excretion; membrane transport and regulation contribute to this
homeostasis. Inorganic sulfate represents a small fraction of total sulfate in the body, which
includes muccopolysaccharides, chondroitin sulfate, glycolipids, steroids, thyroid hormones,
peptide hormones (gastrin), oligosaccharides, and xenobiotics (e.g., drugs). As much as 5 to
10 percent of excreted sulfate is excreted as sulfyl esters.
Dr. Cole and his colleagues conducted studies on the shift in homeostasis between
pregnant and non -pregnant women. They found that pregnant women reabsorb more sulfate
and retain an extracellular pool for placental transfer to the fetus. There are detectable levels
of sulfate in amniotic fluid. Toward the third term, the fetus swallows amniotic fluid, which
passes through the gastrointestinal tract and is eliminated in urine. The fetus also has higher
circulating levels of sulfate than adults do.
A study looking for a gene responsible for diastrophic dysplasia identified the genetic
sequence for one of the four known transporters of sulfate. Apparently, a sulfate deficiency
arises if this transporter does not function properly. During fetal development, sulfate
deficiencies can lead to diastrophic dyplasia (deformed tissues) of the hands and feet,
cognitive and behavioral changes, membrane structural deficiencies, early lethality, and
malformed cartilage. .

Intestinal Physiology of Sulfate
Marie Cassidy, Ph.D., D.S.C., Associate Professor
Department of Physiology and Experimental Medicine, George Washington University
Diarrhea affects more people world-wide than any other illness. Diarrhea caused by
parasites or infections need not be life -threatening if fluids and electrolytes are replenished in a
timely manner because the intestinal lining is replaced every three to four days, thereby
washing out parasites or pathogenic microorganisms. At the apical membrane in the
intestines, cation and anion transport occurs through the cell wall. The World Health
Organization found that introducing solutions of sodium with glucose and amino acids aids in
repairing damage to the apical membrane, allowing water to flow through and between the
cells and restoring ion transport.
In the small intestine, plasma has the same osmolarity as the lumen. In the large
intestine, differences in osmolality between the plasma and the lumen allow water absorption
from the lumen into the large intestinal villi.
Normally there is a balance between absorption and secretion in the intestinal villi.
The presence of substances that increase the rate at which materials move through the
intestine reduces the amount of time available for reabsorption of water and may cause
diarrhea. Diarrhea can also result from an increased secretion of water into the intestinal
lumen, which may be caused by bacterial toxins (Vibrio cholerae, Esherichia coli,
Staphylococcus aureus, Pseudomonas aeruginosa [seen in AIDS patients], Bacillus areus,
Clostridium perfringens, Kiebsiella, Shigella dysenteriae, and Pnueamoniaea ), bile salts,
hormones, or high levels of osmotically active solutes such as sulfate. Congenital diarrhea can
be caused by defective sodium chloride absorption.
In addition to the mechanisms discussed above, increased intestinal hydrostatic
pressure, luminal distention, high luminal osmolarity, plasma dilution, increased mucosal
permeability, increased interstitial hydrostatic pressure, and underlying infections or
impairments (e.g., ulcerative colitis) may cause diarrhea.
Osmotic diarrhea results when there is an excess of unabsorbed osmotically active
particles (e.g., magnesium hydroxide in antacids) present in the intestinal lumen. For example,
magnesium salts, castor oil, and undigested lactose (i.e., in lactose -intolerant individuals) are
osmotically active compounds that can produce laxative effects or cause diarrhea.
Cholesterol -binding drugs increase the concentration of bile salts in the colon, and may cause
diarrhea.
There are antidiarrheal therapies other than sodium, glucose, amino acids, and fluid
replacement. Opiates prolong transit time (the amount of time substances are retained in the
intestines) and promote more efficient absorption, and alpha-2-adrenergic medications inhibit
anion secretion. High concentrations of steroids increase sodium absorption.
In summary, clinical diarrhea is caused by 1) a lack of capacity to absorb fluids or
electrolytes, 2) the presence of osmotically active agents in the intestinal lumen, 3) increased
propulsion causing decreased contact time, or 4) bacterial toxins that stimulate secretion of
Page 13

water into the intestinal lumen. The presence of high levels of sulfate in the intestinal lumen
would not typically affect normal healthy adults, or infants. However, people with
pathophysiology, older people taking certain medications (e.g, to treat diabetes, hypertension,
high cholesterol), people with underlying intestinal diseases, and infants in tourist areas may
be more susceptible to the effects (i.e., diarrhea) of a sudden exposure to high levels of
sulfate.
Discussion
Dr. Shy asked whether drugs to inhibit cholesterol interact with sulfate in water to
make it more hyper -osmotic. Dr. Cassidy said that she believes they would because anything
that will increase the levels of bile salts in the intestines would be likely to cause loose stools.
Another concern is that older people may be more susceptible to high sulfate levels if they are
taking cholesterol -lowering drugs or if they have underlying health problems.

Effects of High Sulfate Exposures
Marilyn Morris, Ph.D., Associate Professor
Department of Pharmaceuticals, State University of New York at Buffalo
Elimination of sulfate occurs through urinary excretion. In the proximal tubule of the
kidney, sulfate is reabsorbed across the brush border membrane into the cells and exits via the
basolateral membrane. Sulfate and sodium are reabsorbed into renal proximal tubular cells
through a part of the membrane sequence known as NaSi-1. The cells comprising the
intestinal ileum also contain the genetic sequence for the NaSi-1 transporter. Another
transport mechanism, the sodium -independent sulfate anion exchange transport (SAT-1), is
present in muscle and brain. Exposure to certain drugs, such as nonsteroidal antinflammatory
drug treatments or hormone therapy; changes in dietary levels of sulfate, age, pregnancy; and
disease states, such as hypothyroidism, can affect sulfate transport mechanisms.
Bauer (1976) found 85-90% absorption of sulfate at high concentrations; most of the
absorption occurred in the ileum. In a recent study, Dr. Morris and her colleagues gave diets
containing different amounts of methionine, an amino acid and sulfate -precursor, to rats. A
diet containing three times more methionine than the control diet decreased reabsorption of
sulfate from the intestine but produced little difference in serum sulfate levels. The
researchers concluded that the body can compensate for different levels of sulfate. Compared
to the levels of NaSi-1 messenger RNA (mRNA) in control animals, the levels of NaSi-1
mRNA were increased in animals that were fed the low sulfate diets, and decreased in animals
that were fed higher levels of methionine in their diets.
In an experiment using neonatal, young, and adult Guinea pigs, the younger animals
reabsorbed sulfate and sodium at higher rates than the adult animals did. Pena and Neiberger
(1997) reported that young guinea pigs fed diets high in sulfate maintained serum sulfate
concentrations within the normal range by increasing urinary excretion of sulfate.
Diastrophic Dysplasia Sulfate Transport (DDST) is an anion exchanger present in the
intestine and in many other tissues. The Down Regulated in Adenoma (DRA) gene encodes
an intestine -specific membrane sodium -independent sulfate transport protein. This gene is
expressed in the normal colon and also in the small intestine of mice and humans. There is a
59% overlap between the genetic sequences for DRA and SAT-1 and a 60% overlap between
DRA and DTDST.
At least one series of sulfate anion exchangers is known to be present in the intestine,
and there may be others. At this point little is known about the function of these exchangers
or about how sulfate absorption is regulated in the intestine.
Cocchett and Levy (1981) reported that, in human research subjects, a single dose of
8g of anhydrous sodium sulfate caused diarrhea. However, 8g of anhydrous sodium, sulfate
divided into four 2-gram doses, given at hourly intervals, did not cause diarrhea. In another
study (Morris and Levy, 1983), the same millimolar dose of sulfate provided from magnesium
sulfate caused adverse effects ranging from upset stomach to diarrhea. Sixty percent of the
Page 15

sodium sulfate given in divided doses was absorbed, whereas only 35% of the magnesium
sulfate was absorbed. These results indicate that the source of the sulfate (e.g., from the
magnesium or sodium salt) is important in determining the extent and nature of any potential
adverse effects.
The potential adverse effects of high sulfate ingestion include: 1) diarrhea, 2)
alterations in sulfation (e.g., metabolism of hormones, catecholamines, and bile acids), and 3)
changes in calcium and magnesium metabolism that increase urinary excretion (e.g., increased
concentrations of calcium sulfate complexes .are found in renal disease patients).
Galinsky and Levy (1981) studied the concentration of acetaminophen in plasma and
found that sulfate depletion decreased sulfation, thereby increasing the amount of
acetaminophen that remained in plasma. They also found that, in infants, the sulfonation of
acetaminophen occurs more efficiently than it does in adults. Freeman and Richards (1979)
found that sulfate and creatinine are not removed by dialysis. Patients with acute renal failure
tend to have the highest serum sulfate concentrations, but there have been no acute toxic
effects noted from sulfate retention in this circumstance.
Discussion
Dr. Cassidy asked about the connection with renal disease. Dr. Morris answered that
the connection between the two is related to the failure of reabsorption, that is, decreases in
filtration cause serum sulfate concentrations to increase. Dr. Cole said that in a study of
premature infants, he found a relationship between increased sulfate loading and the amount
of total sulfoester, but no toxic effects. Dr. Shy asked Dr. Morris to clarify her point about
how one of the potential adverse effects of high sulfate is a possible alteration in sulfation, and
asked if this alteration could influence metabolism. Dr. Morris suggested that altered sulfation
could have an impact on metabolism, but stated that this possibility has not been directly
examined. However, research has indicated that metabolism may be affected if sulfate
concentrations are too low.

'Gastrointestinal Effects of Sulfate in Drinking Water: Baby Pig Study
Guillermo Gomez, Ph.D, M.S., Senior Scientist
Director, NCSUPiglet Core, Department of Animal Science, North Carolina State
University
The study reported herein was conducted at the North Carolina State University
(NCSU) Piglet Core through the Center for Gastrointestinal Biology and Disease with a grant
from the EPA .' This study used artificially -reared neonatal piglets as a model to evaluate the
effect of inorganic sulfate on bowel function in human infants. Two experiments were
conducted to evaluate the effect of high levels of sulfate on the growth, feed intake, and feces
consistency of artificially -reared piglets and to determine the dose at which at least 50% of the
pigs developed nonpathogenic diarrhea. The effect of dietary sulfate level on kidney weight
and the concentration of sulfate in urine was also assessed.
Newborn piglets were left with their dams for approximately 48 hours and then
transferred to an isolated room containing an automated feeding device (Autosow). Piglets
were fed a basal diet with no added sulfate and were allowed to adapt to the new environment
for a 3- to 4-day period. The Autosow is a machine containing individual cages that regularly
aseptically dispenses small volumes of liquid diet according to the weight of each piglet.
Piglets were fed liquid diets only and did not have access to drinking water. The diet reservoir
was refrigerated; therefore, bacterial growth in the diets was minimal. In each experiment, at
the end of the adaptation period (at an average age of 5 days), 40 piglets were weighed and
distributed according to body weight, sex, and litter origin into four groups. Ten individually
reared piglets per dietary treatment were fed one of four diets containing the following levels
of added inorganic sulfate (mg/L of diet), as anhydrous sodium sulfate (USP): 0, 1200, 1600,
and 2000 for Experiment 1 (18-day study), and 0, 1800, 2000, and 2200 for Experiment 2
(I6-daystudy). Inorganic sulfate was dissolved in deionized, distilled water before the other
dietary ingredients were added. The deionized, distilled water contained <1 mg inorganic
sulfate/L; the basal diets of Experiments 1 and 2 contained 277 and 261 mg inorganic
sulfate/L, respectively. Details of the experimental protocol have been published elsewhere
(Gomez et al., 1995).
The levels of added sulfate did not affect (p < 0.05) the growth of the piglets or their
feed intake. Whereas 1200 mg added sulfate/L had essentially no effect on feces consistency,
levels >1800 mg/L of diet resulted in a persistent, nonpathogenic diarrhea in neonatal piglets.
Added sulfate did not affect relative kidney weight (p < 0.05). Inorganic sulfate in urine
reached maximum concentration in pigs fed diets with 1600 and 1800 mg added sulfate/L in
Experiments 1 and 2, respectively (p < 0.05), but declined at higher levels. The changes in
feces consistency suggest that the level of added dietary inorganic sulfate at which 50% of
piglets develop nonpathogenic diarrhea is between 1600 and 1800 mg/L.
'Although the research described in this presentation has been supported by the U.S. EPA, it has
not been subjected to agency review and, therefore, does not necessarily reflect the views of the agency.
Page 17

Discussion
Dr. Morris clarified that the basal amount of sulfate in Dr. Gomez's study was 270
mg/L, that the actual amount of added sulfate was 1,600 mg/L, resulting in a total amount of
1,870 mg/L given to the piglets. Dr. Shy asked if fifty percent of the animals got diarrhea at
1,600-1,800. Dr. Gomez answered that, at 1,600 mg/L, 50% of the piglets got diarrhea, but
that at 2,000 and 2,200 mg/L, all piglets had diarrhea.
Dr. Shy asked if there was a difference between animals fed 0 mg/L and those fed
1,200 mg/L. Dr. Gomez responded that there was no effect at 1,200 mg/L, so that level was
a safe limit for piglets. Dr. Cole pointed out that the definition of "no effect" is subjective.
For example, a pediatrician may have a different definition of "no effect" than a mother who
observes changes in the number, frequency, and volume of her infant's stools.
Dr. Gomez noted that studying neonatal piglets for three weeks before weaning is
comparable to following a baby for six to nine months. While the study measured sulfate in the
urine, the equipment did not allow measurement of urine or feces volume. Dr. Cole asked
whether the piglets could have shown adaptation at all but the highest sulfate levels. Dr.
Gomez said that he did not measure adaptation, but did find that all piglets grew at the same
rate, so there was no effect on growth.
Ms. Joyce Tsuji, of Wheeler Environmental Corporation, was surprised that the piglets
showed no dehydration or weight loss. Dr. Gomez responded that his group was also
surprised by this outcome. He noted that piglets with rotovirus do become dehydrated and
eat less.

Health Effects from Exposure to High Levels of Sulfate in Drinking Water
Lorraine Backer, Ph.D., M.P.H., Epidemiologist
National Center for Environmental Health, Centers for Disease. Control and Prevention
Sulfate is a substance that is occurs naturally in drinking water. Health concerns
regarding sulfate in drinking water have been raised because of reports of diarrhea associated
with the ingestion of water containing high levels of sulfate. Of particular concern are groups
within the general population that may be at greater risk from the laxative effects of sulfate
when they experience an abrupt change from drinking water with low sulfate concentrations
to drinking water with high sulfate concentrations.
There are very few scientific reports describing the health effects of exposure to sulfate
in drinking water, and the concerns regarding sensitive populations are based on case studies
and anecdotal reports. One such potentially sensitive population is infants receiving their first
bottles containing tap water, either as water alone or as formula mixed with water. Another
group of people who could potentially be adversely affected by water with high sulfate
concentrations are transient populations (i.e., tourists, hunters, students, and other temporary
visitors) and people moving into areas with high sulfate concentrations in the drinking water
from areas with low sulfate concentrations in drinking water.
The objective of the CDC/EPA studies on the health effects of exposure to sulfate was
to provide additional information regarding whether sensitive populations (infants and
transients) may be adversely affected by sudden exposure to drinking water containing high
levels of sulfate. Specifically, the researchers involved designed a field investigation of infants
exposed to naturally occurring high levels of sulfate in the drinking water provided by public
water systems and an experimental trial of exposure in adults.
In collaboration with the State Health Departments of New Mexico, South Dakota,
and Texas, we planned a prospective cohort study of infants who would be exposed to tap
water used to mix infant formula. We planned to recruit women in their third trimester of
pregnancy. Infants were to be enrolled at birth and followed for 4 weeks to determine if there
was an association between exposure to drinking water containing varying levels of sulfate
and reported cases of diarrhea.
For a woman to be included in our study, she had to be: (1) accessible through a clinic
that offers prenatal care, (2) 35 to 36 weeks pregnant (to exclude severely premature infants
and to be able to interact with the woman at her next prenatal visit), (3) not planning to breast
feed her baby, (4) planning to feed her infant concentrated formula mixed with her home tap
water (can be boiled), (5) planning to be at home with her infant for at least one month, (6)
living in a home (private house, apartment, mobile home, etc.) that is served by a public water
supply and that does not have a water filtration system, and (7) able to read the study
instruments in either English or Spanish.
Using historic water quality data for secondary drinking water constituents (including
concentrations of sulfate) provided by the states and Geographic Information System (GIS)
techniques, we generated maps of the geographic distribution of each water system that
Page 19

simultaneously identified the level of sulfate in the water and the size of the population each
system serves. Based on the GIS maps, the number of expected births in the participating
states, the inclusion criteria we have described, and the assumption that 25% of infants are not
breast-fed, we planned a six-month recruiting period. We planned to enroll a maximum of
880 infants, 110 each from water systems within the following ranges of sulfate: < 250 mg/L
(baseline or comparison group), 251-500 mg/L, 501-700 mg/L ,and a maximum of 550 infants
from water systems with sulfate levels greater than 701 mg/L.
We conducted a pilot study of the planned recruitment methods and study instruments
in four counties in South Dakota. Local Public Health Nurses, who already had rapport with
clinic patients, were hired and trained to recruit study participants and conduct the activities
associated with the study. In the 4 counties (served by 3 Community Health Clinics), 72
women were approached about participating in the study during their prenatal visit to the
public health clinics. Of these 72 women, 30 were ineligible because they planned to breast-
feed their infant, 23 were ineligible because they planned to use water other than tap water to
mix infant formula, and 11 were ineligible because they did not meet other eligibility criteria.
Eight women were eligible to participate in the study; three refused, five women
agreed to participate, and one woman completed all the study activities. Of the four women
who did not complete the study activities, two switched to bottled water as the source of
water to mix with infant formula, one chose to use ready -to -feed formula after two weeks of
using the powdered formula, and the fourth moved out of the area.
Because we experienced recruiting problems during the pilot study, we developed a
self-administered questionnaire (SAQ) to examine tap water use. The questionnaires were
developed in both English and Spanish and were provided to all women who came to one of
32 clinics in the previously identified geographic areas of New Mexico, South Dakota, and
Texas. The SAQ asked questions about the source of their home tap water, what mothers of
infants <3 months old were currently feeding their babies, and how currently -pregnant women
planned to feed their infants.
Overall, the results from the SAQ indicate that more than half (61 %) of pregnant
women report planning to breast-feed their infants. In addition, of those who plan to use
infant formula mixed with water, most (84%) plan to use water other than tap water. These
results are consistent with our experiences during the pilot study and indicate that only a very
small percentage of women who live in areas with high levels of sulfate in the tap water
provided by public water systems plan to give this water to their infants.
To examine how many of the women who completed the SAQ would have been
eligible to participate in our study, we examined the responses of women who received their
tap water from public water systems and who did not have filters on their home taps and
found that 403 women with infants < 3 months of age and 761 pregnant women met these
eligibility criteria. The highest proportions of women who had used or were planning to use
tap water to mix infant formula were in the four counties with average sulfate levels < 250
mg/L. Of the 365 pregnant women in areas with sulfate levels > 250 mg/L, 226 (62%)
planned to use infant formula. However, only 39 (11%) planned to use infant formula mixed
Page 20

with their tap water. Of the 183 women with infants <_3 months old in areas with sulfate
levels > 250 mg/L, 151 (83%) used infant formula, but only 35 (19%) reported having used
infant formula mixed with their tap water.
The other population potentially sensitive to abrupt exposure to high levels of sulfate
in drinking water is transient adults (students, visitors, hunters, etc.). To study the effects on
adults of suddenly changing drinking water sources from one that has little or no sulfate to
one that is high in sulfate, we conducted an experimental study involving volunteers from
Atlanta, Georgia, including CDC employees and employees at the U.S. EPA Region IV office.
Volunteers were randomly assigned to one of five sulfate exposure groups (i.e., 0, 250, 500,
800, or 1200 mg/L sulfate from sodium sulfate in bottled drinking water) and were provided
with bottled drinking water for six days. The bottled water for days 1, 2, and 6 contained
plain water, the bottles for days 3 through 5 contained added sulfate. The unfinished or empty
bottles were returned and weighed to determine how much water was consumed each day.
Volunteers were blinded to the level of sulfate in their drinking water.
One hundred five study participants were divided among the dose groups as follows:
24 received 0 mg/L sulfate; 10 received 250 mg/L sulfate; 10 received 500 mg/L sulfate; 33
received 800 mg/L sulfate; and 28 received 1200 mg/L sulfate. We analyzed the number of
bowel movements recorded each day by study participants. There were no statistically
significant differences in the mean number of bowel movements among the groups on days 3,
4, 5, or 6. There were also no statistically significant differences in the mean number of bowel
movements reported when comparing days 1 and 2 (the days when there was no sulfate in the
water) with days 3, 4, and 5 within each dose group.
The frequencies of diarrhea reported by individuals exposed to varying levels of sulfate
in their drinking water are presented in the table. Three different definitions of diarrhea were
used: increase in stool volume compared to normal, change in stool consistency to liquid or
paste, and increase in volume/change in consistency. Because the effect of sulfate is
dependent on both the weight of the participant and the amount of water each consumed
(dose/kg of body weight), we used logistic regression to examine the reported frequency of
diarrhea (using the three different definitions described above) by sulfate dose ([concentration
of sulfate in water x volume of water consumed on days 3, 4, and 5]/body weight) in
individuals who reported normal stool volume on days 1 and 2 and who did not have family
members who experienced vomiting or diarrhea on days 3, 4, or 5). Sulfate dose was not a
statistically significant predictor of diarrhea in any of the models (p >_ 0.80 for all models).

To examine the data for a trend toward increased frequency of reports of diarrhea with
increasing dose, we included the dose as an ordinal variable in a logistic regression model of
osmotic diarrhea. Again, there was no statistically significant increase in reports of diarrhea
with increasing dose (one-sided p = 0.099).
The over-all purpose of these studies was to examine the association between
consumption of tap water containing high levels of sulfate and reports of osmotic diarrhea in
susceptible populations (infants and transients, i.e., those acutely exposed). We had to cancel
a planned study of infants because we could not identify enough exposed individuals from
which to draw a study population. The results of our SAQ examining tap water use indicated
that most pregnant women who completed the survey plan to breast-feed their infants. Of
those who plan to use formula mixed with water,. most do not plan to use tap water to mix the
formula. In our experimental trials with adult volunteers, we did not find an association
between acute exposure to sodium sulfate in tap water (up to 1200 mg/L) and reports of
diarrhea.

Sulfate in Drinking Water," accompanies this workshop summary.
Evaluation of The Association Between Infant Diarrhea and Elevated Levels of Sulfate
in Drinking Water: A Case -Control Investigation in South Dakota
Lorraine Backer, Ph.D., M.P.H., Epidemiologist
National Center for Environmental Health, Centers for Disease Control and Prevention
Dr. Emilio Esteban, et al. conducted an investigation of diarrhea in infants in South
Dakota who ingest water containing various levels of naturally -occurring sulfate. In that
state, 110,000 people live in areas (19 counties) with elevated sulfate levels. In these
counties, there were 366 births between January and March 1995, and 264 new mothers were
interviewed using a telephone questionnaire. The infants were 6.5- to 30-months-old at the
time of the interviews. Interviewers asked the mothers report the number and consistency of
their infants' bowel movements, whether their infant had diarrhea (defined as 3 or more loose
stools in a 24-hour period), and the quantities of water consumed by their infants in the
previous seven days. Mothers were also asked to provide a sample of the water they used in
the baby's diet. The water samples were analyzed for sulfate levels.
Cases were defined as infants with diarrhea (as reported by the mother) and control
subjects were defined as infants who did not develop diarrhea. The mean concentration of
sulfate in the water in the homes of cases was 392 mg/L, and in the homes of control subjects
was 358 mg/L. Sulfate intake was 31 mg/kg body weight for both groups. Mothers reported
diarrhea in nineteen percent of the infants living in households with sulfate levels in tap water
> 500 mg/L h, and in 14 percent of infants living in households with sulfate levels < 500 mg/L.
This study revealed no .association between exposure to sulfate from tap water and subsequent
diarrhea.
Discussion
Dr. Cassidy asked if higher sulfate levels match higher calcium or magnesium levels.
Dr. Backer said that geographic areas with high sulfate levels in drinking water sources also
tend to have high levels of other salts and minerals, but the association is not consistent. Dr.
Cassidy asked whether, in the areas of Dr. Backer's study, there is any sort of folklore
pertaining to why women are not choosing tap water for formula. Dr. Backer responded that
she did not hear any folklore but that the women probably tended not to use tap water for
drinking because it smelled and/or tasted bad. Dr. Backer also noted that the areas that have
very high sulfate levels tend to be rural and poor. Potential study participants were identified
through Women, Infants, and Children (WIC) clinics and it is possible that women reported
breast-feeding, even if they had or were planning to bottle-feed their babies, because WIC
clinics encourage breast-feeding.
Dr. Morris stated that she thinks researchers might be more successful in getting
women to use a certain infant formula if the women were provided, free -of -charge, with a pre -
diluted, ready -to -use formula, with known amounts of sulfate. Dr. Abernathy responded to
Page 23

this proposal by saying that adding sulfate to infant formula poses an ethical problem. The
study would only be acceptable to CDC's Institutional Review Board (IRB) if women
planning to use tap water to mix infant formula for their newborn infants could be identified in
geographic areas with varying levels of sulfate naturally occurring in the tap water. Diane
Burkom, from Battelle, added that even trying to influence a mother to use a certain brand of
formula that is naturally high in sulfate would be ethically questionable. Also, in the rural
areas where the sulfate levels are high, most women were already provided with free infant
formula by WIC clinics, leaving little with which to entice the mothers. Dr Cole pointed out
that with a large study sample, some diarrhea will inevitably occur that is unrelated to the
study, but which might be attributed to the study.
Dr. Cassidy asked Dr. Backer how long the adult study lasted. Dr. Backer responded
that it lasted six days, with exposure for three days, in an effort to mimic the effect of transient
exposure.
Dr. Cole commented that, in Europe, mineral water (containing up to 250 mg/L
sulfate) is considered soothing, indicating that there is a public perception that small amounts
of sulfate may be beneficial and that this perception may be supported by the results from the
adult study (the lower frequency diarrhea among study participants who consumed water
containing 250 mg/L sulfate compared to the group who consumed plain bottled water.
However, as Ms. Tsuji mentioned, the 250 mg/L exposure group did have a small sample size
(n = 10), and the differences in diarrhea frequency between the two groups was not
statistically significant.
Dr. Gomez asked if microbial analysis was performed on the bottled water used in the
adult study. Dr. Backer indicated that she received a full report of the chemical and microbial
analyses done on the lots of water used for the adult study. Dr. Abernathy stated that the
American Academy of Pediatrics has guidelines for sulfate levels in drinking water because it
has not seen a problem with sulfate ingestion.
Dorothy Wombly, from EPA Region 5, said that most mothers are told not to use tap
water for their infants or to boil it before use. Diane Burkom made the point that boiling
water for the amount recommended by formula manufacturers (1 minute) would have no
effect on the sulfate concentration. Dr. Backer said that people in the study sites were using
water from many sources, including kiosks that provided filtered water (from public water
systems). Bonita Johnson, from EPA Region 4, asked if the types of food people eat have an
effect on diarrhea. Dr. Backer responded that some types of food could have an effect, but
that they did not ask about food consumption in the study.
Page 24

Discussion of Key Issues
Dr. Shy introduced the issues to be discussed by the participants. He stated that the
goal of the workshop was not to reach a consensus, and that the discussion should include all
points of view. The purpose of the workshop was to discuss the scientific evidence regarding
human health effects from exposure to sulfate in drinking water and whether there is sufficient
scientific evidence of a dose -response.
Issue 1 Do reported studies suggest that a certain sulfate level would not be
likely to cause adverse effects (e.g., diarrhea in infants and travelers)?
Existing data do not identify the level of sulfate in drinking water that
would be unlikely to cause adverse human health effects. The panel
members noted that the available published literature included reports
that piglets in experimental feeding trials and some people experience a
laxative effect when consuming diets (piglets) or tap water (humans)
containing from 1,000 to 1,200 mg1L of sulfate (as sodium sulfate).
However, none of the studies found an increase in diarrhea,
dehydration, or weight loss.
Dr. Abernathy clarified that EPA wanted to base any possible sulfate regulation on
people who had no specific diseases or underlying conditions. Dr. Cole asked whether this
category of people would be separate from the category including infants, elderly, and
travelers. Dr. Abernathy said that EPA wants to focus on infants and travelers, and that
people who are taking certain medications or have certain diseases would be considered a
separate category. Dr. Cassidy stated that it makes a difference whether the exposure is to
magnesium or sodium sulfate, and asked if either of these salts had an odor. Dr. Abernathy
responded that the regulation, if one were developed, would likely be written for total sulfate
level, and would be based on EPA's current interpretation of the statute (SDWA).
Dr. Shy began the discussion by looking at the Heizer et al. (1997) study on the
intestinal effects of sulfate in drinking water on normal human subjects. He mentioned that, in
the dose -response study, the only effect was decreased transit (mouth -to -anus) time. In the
single dose study, 1,200 mg/L caused a significant, but mild, increase in mean stool mass. Dr.
Shy said that this study is the most important when considering effects on normal adults. Dr.
Morris commented that there is no indication from either the literature or the new data
presented at the workshop that 500 mg/L is associated with any toxicity. Dr. Shy asked again
about the findings regarding 1,200 mg/L in the Heizer et al. (1997) study. Dr. Cassidy
responded that the level seems to be mildly cathartic but not toxic. Dr. Abernathy said that it
was important to note that the study only had 10 subjects, so it would be difficult to make a
definitive statement based on such a limited study.
Dr. Cole reiterated Dr. Cassidy's point that, in adults with no other health issues, 500
mg/L seems to be a safe level to ingest in drinking water. Dr. Morris echoed this point by
stating that 500 mg/L is shown to be safe in all studies. Dr. Shy asked if the findings in the
Chien et al. (1968) paper were consistent with the other studies in reporting that exposure to
drinking water containing 500 mg/L sulfate had no effect. Dr. Morris noted that in the Chien
Page 25

et al. (1968) study, the sulfate levels that caused diarrhea in the three infants were 630, 720,
and 1,150 mg/L. Dr. Abernathy pointed out that case reports, such as Chien et al. (1968), are
notoriously difficult to interpret. He observed that there were many uncontrolled variables in
that study, such as the osmolarity of the infant formula and the concentrating effect of boiling
the water. Dr. Cole added that infant formula in Canada in 1968 was not controlled at all.
Even if the formula was dry cows' milk, cows in that area could have ingested high levels of
sulfate from their drinking water.
Dr. Shy then asked the panel to consider table of results from the study by Moore
(1952), and asked, if they could say there was no laxative effect at different levels of sulfate.
Dr. Cole said that the Moore (1952) study was a bivariate analysis, and that it was possible
that, if one conducted a multivariate analysis of the data (considering, for example, the
relationship of iron in some of the waters), there might be different results. Dr. Abernathy
said that he was not able to get the original data from that study to do a multivariate analysis.
In response to Dr. Cole's mention of iron as a possible variable in a multivariate analysis, Dr.
Cassidy added that iron causes a constipation effect, not a laxative effect. Dr. Gomez pointed
out that the Moore (1952) paper does not look at how persistent the effects were. Dr.
Abernathy also added that it was a questionnaire with subjective answers to the question
about diarrhea.
Dr. Shy cautioned participants to remember that they were trying to determine the
level of sulfate at which there is no human health effect. Irene Dooley reiterated that the
results from the studies conducted by CDC and EPA did not find a dose -response association
between exposure to sulfate in drinking water and diarrhea; therefore, the literature and this
workshop will be key sources of information when the agency makes a regulatory
determination. Adding to this clarification, Dr. Abernathy said that the workshop panelists
do not have to agree on a definitive value. The EPA would like to know whether anyone
would be comfortable saying that "at X mg/L of sulfate in drinking water a healthy human is
unlikely to have an adverse health effect, but the likelihood of experiencing an adverse health
effect may increase with increasing sulfate levels."
Dr. Backer asked if the panelists, in defining the health outcome, are looking for a
laxative effect or diarrhea specifically. She pointed out that the distinction is not made clear in
the different studies. Dr. Cassidy clarified that a laxative effect can be beneficial, but constant
diarrhea can cause problems. Dr. Cassidy stated that clinical diarrhea must be chronic to be
considered a problem for an individual. Dr. Abernathy said a doctor told him that
gastrointestinal distress lasting a week is not a problem for a healthy tourist. Dr. Cole said
that diarrhea can be defined as 1) what a mother perceives as diarrhea, or 2) a situation that
actually warrants an emergency room visit for intervention because of dehydration, based on
stool volume and frequency. He noted that since the American Pediatric Association issues
nothing about sulfate, it doesn't perceive a correlation between sulfate and diarrhea.
Dr. Shy pointed out that Moore (1952) looked at a "laxative effect," which is not
necessarily an adverse human health effect. Dr. Morris suggested that we can take 0-200
mg/L as a baseline. At 500-1,000 mg/L there is only a 10 percent increase in laxative effect,
and at 1,000 mg/L 62% of respondents report experiencing a laxative effect.
Page 26

Dr. Shy brought the discussion back to the Heizer et al. (1997) study. In this study,
six people drank plain water (containing no added sulfate) for six days, followed by six more
days in which they drank water containing 1,200 mg/L added sulfate. Study participants did
not report having diarrhea (no increase in stool frequency or consistency), but did report an
increase in stool bulk. This study was controlled (although small) and did not show adverse
health effects in adults from exposure to sulfate in drinking water. The second study reported
by Heizer et al. (1997) involved a gradual increase in sulfate level. There were no reported
health effects from this exposure. Dr. Morris noted that the Heizer et al. (1997) study used
sodium sulfate. Dr. Gomez stated that, in his study of baby pigs exposed to 1,200 mg/L
sulfate (as sodium sulfate), the pigs did not get diarrhea.
Dr. Shy then raised the question of special populations, such as neonates. He
reiterated that the Esteban et al. (1997) study included infants (6.5 to 30 months of age), but
found no association between the level of sulfate exposure and diarrhea reported by the
mothers..Dr. Cassidy pointed out that the Chien et al. (1968) study involved only three
infants. Dr. Shy repeated that we do not know the total amount of sulfate (including formula
and tap water) that the infants received in the Chien et al. (1968) report. They received at
least 630 mg/L, but the amount could have been higher. Dr. Cassidy said that Chien et al.
(1968) proposed 400 mg/L as a tentative acceptable level for infants. She added that there is
no evidence in the literature that sulfate causes problems for the elderly.
Bob Benson, from EPA Region 8, referring to Dr. Cole's comment that water with
sulfate levels of >_ 1,000 mg/L are hyper-osmolar, asked at what point the osmotic pressure in
the lumen would equal the osmotic pressure in the intercellular fluid. Dr. Cole responded
that, for sodium sulfate, the concentration would be close to 40,000 /.zosmoles of sulfate. The
study by Gomez et al. (1995) shows that even though sulfate anions are not enough to draw
intracellular fluid into the lumen, sulfate interaction with the cellular structure affects the
transfer of water. Also, there is some biological evidence to suggest that sulfate does interact
to change cellular physiology in the gut. However, the Gomez et al. (1995) study showed
that the diarrhea observed in the piglets is not purely an osmotic diarrhea because that would
be expected produce weight loss and dehydration, and the piglets did not experience either.
Dr. Cassidy reported that there is also a physiological mechanism that balances the
effects of changes in osmolarity and maintains ion and water transport across the lumen. Even
with hyper-osmolar diarrhea, the body eventually will adjust the osmolarity of the lumen to
balance water absorption and loss.
Issue #2 Does the literature support acclimatization or adaptation (what process
and time frame does it take)?
Based on biologic plausibility and anecdotal reports, evidence indicates
that people acclimate to the presence of sulfate in drinking water. In
addition, serum sulfate levels are high (compared to adults) in human
fetuses and neonates (to support rapid growth and development).
However, data describing acclimation and the changes in sulfate
metabolism during growth and development are limited.
Page 27

Dr. Cassidy responded that there is very little information on acclimatization, but,
based on pathogenic responses, evidence indicates that sulfate acclimatization would probably
occur within 3-4 cell cycles, over the course of one to two weeks. Dr. Cole indicated that his
opinion, based on kidney changes, Gomez's study, clinical results, and anecdotal evidences, is
that acclimation is a theoretically possible biologic process. Dr Cole suggested, however, that
the evidence that acclimation occurs is not fully convincing. Dr. Gomez said that in his
relatively long, 18-day study, the piglets did seem to acclimate to sulfate.
Dr. Shy asked the participants to consider the issue of travelers versus residents and
Dr. Morris asked if EPA would consider setting levels for all people living in an area or just
for infants starting on formula and travelers? Dr. Abernathy mentioned that EPA has
considered, in the previous proposal, posting signs for travelers. He added that providing
bottled water for infants in certain areas is also an option.
Ms. Tsuji asked if neonates acclimate faster because they are growing. She also asked
if the data presented by Dr. Cole regarding high sulfate levels in amniotic fluid suggested that
infants suffer fewer adverse health effects from exposure to high levels of sulfate because they
acclimate more quickly. Dr. Cole responded that both intra-cellular sulfate and intervascular
sulfate are elevated before birth and during some period after birth to support growth and
development. But the infant gastrointestinal tract is somewhat more permeable to salts and is
more sensitive than that of an adult. If powdered milk (which has high osmolarity) is pushing
the infant gastrointestinal tract to its limit, high levels of sulfate from another source (such as
tap water) could cause diarrhea. Dr. Cassidy added that the configuration and shape of the
infant's intestinal cells depend on the diet. Dr. Morris stated that sulfate transport
mechanisms develop over time, and that the process has not been studied. Bat (1969) found
that, in adult rats, transport and absorption occurred in the ileum. Neonatal rats had a
different distribution of sulfate in tissues, suggesting changes in the mechanisms of sulfate
absorption during different stages of development.
Bill Hiatt, from BASF Corporation, suggested that a developmental effect would
justify a higher level of concern for establishing a primary drinking water standard than would
a transitory effect among travelers. Dr. Cole noted that people may be likely to protect their
infants by using bottled water.
Issue #3 Can an infant study be done for dose -response anywhere in the U.S. or
Canada?'
The difficulty in locating a population of women feeding their infants
formula mixed with unfiltered tap water containing high levels of
sulfate hinders the completion of an infant study of the dose -response to
sulfate exposure. A study using neonatal pigs could assess a dose
response for both magnesium and sodium sulfates.
Dr. Backer began by stating her opinion, based on recruitment efforts for the study she
attempted to conduct, that it is not possible to do a population -based study in the United
States that includes infants naturally exposed to varying levels of sulfate from tap water
provided by public water systems. Dr. Cassidy said that such a study could be done only as an
Page 28

animal study, and that piglets are the best model to use. She added that such a study could
include intestinal biopsies to establish the mechanism by which sulfate exerts its effects. She
also suggested looking at other parameters as well, such as renal function.
Irene Dooley said that EPA traditionally uses a safety factor of 10 for transfer of
animal to human results, which, for the Gomez et al. (1995) study, would suggest limiting
levels of sulfate to 160-220 mg/L. Dr. Cole responded that, while there perhaps should be a
factor, in this case he does not think a factor of 10 makes sense because there is no
biotransformation (e.g. activation) of the compound. Mr. Benson asked panelists if they agree
that a safety factor of 10 was not needed when extrapolating from piglets to humans. Dr.
Cassidy said that researchers do not use pigs often because they are very expensive, but they
are much better models for human intestinal physiology than other animals such as rodents
(i.e., studies have shown that the tissue in the gut of piglets and infant humans is very similar).
Dr. Abernathy explained that FDA, in 1954, derived a safety factor of 100 for "no -
observed effect levels" (NOEL) of animal studies. Since that time, the safety factor has been
split into two 10-fold multipliers (a 10-fold safety factor when extrapolating from normal to
sensitive humans and a 10-fold safety factor when extrapolating from animals to humans).
Empirical data compiled by Dourson and Stara (1983) has shown that the variation among
various factors, e.g., subchronic to chronic effects, could often be accounted for by using a 3-
fold factor, indicating that the usual 10-fold factors are sufficient. The World Health
Organization referred to these factors an acceptable daily intake (ADI) and safety factor (SF),
but EPA now uses the terms Reference Dose (RfD) and Uncertainty Factors (UF). However,
depending on the completeness of the data base, the 10-fold OF does not have to be
employed. For example, the data base on nitrate/nitrite and fluoride contained a lot of data on
human exposures, and EPA used an OF of one.
Dr. Cole stated that results using the piglet model of human intestinal physiology
would require a safety factor less of than 10. He mentioned that Stephanie Atkinson studied
the tolerance of phosphate in infant formula by neonates, particularly low -birth weight and
premature infants. Data on the effects in neonatal piglets was directly comparable to that on
the effects in human infants (i.e., no safety factors were applied). Dr. Cole suggested a safety
factor between 1.5 and 2 for neonatal piglets and human infants.
Dr. Gomez added that an important component of this kind of research is that work
with baby pigs is done in departments of animal veterinary sciences, but should be done in
connection with medical schools (especially by pediatricians).
Dr. Shy summarized the panelists' discussion, including the need for a dose -response
study using an animal model and the determination of an appropriate safety factor for
extrapolation of results from animals to humans. Dr. Cassidy added that it would be
important to also look at magnesium sulfate, as well as sodium sulfate.
Dr. Shy said that we can assume that other countries have areas where the sulfate
levels in drinking water are high, but asked if an infant study be ethically acceptable. Dr.
Cassidy repeated Dr. Cole's observation that said it would be unlikely that researchers could
identify an exposed infant population, partly because if infants get diarrhea, mothers will find
Page 29

an alternate source of water. Dr. Shy wondered whether it would be possible to identify
exposed infants if a study were to start with new mothers. Dr. Cassidy brought up the
possibility of doing a pediatric survey in Europe where sulfate levels are high. Dr. Cole
cautioned that those surveys cannot always eliminate the effects of other constituents of
drinking water. He suggested that such a survey could be done in the developing world, but
that doing so may be logistically difficult. He added that women everywhere use the cleanest
water for their infants. Diane Burkom, from Battelle, said that in considering other possible
sources of the diarrhea, the researchers limited their study to public water supplies because
private wells have a higher risk for bacterial contamination than public water supplies do. Dr.
Cassidy added that pathologic bacterial diarrhea would be an issue in the developing world.
Dr. Shy asked about conducting a randomized trial in a place that had a natural sulfate
level of 1,000 mg/L and no alternative water sources. Study participants could be provided
with water containing either 0 or 500 mg/L added sulfate, and the health outcome would be
diarrhea. He asked panelists whether such a trial would be ethically acceptable, pointing out
that if the trial is conducted at a site which has a normal sulfate level of 1,000 mg/L, and no
other water supply choices, the study would provide study subjects with water that contained
less sulfate than they normally would be exposed to. Dr. Gomez said that Peru uses
rainwater, which is easy to collect, as a source of drinking water and that hygiene and viruses
are more difficult to control in a developing country. Dr. Cole said a study would be
theoretically possible, but that an Institutional Review Board (IRB) would not sanction the
protocol, since the researchers would, after determining that the high levels of sulfate caused
illness, possibly leave the community and not provide a permanent source of improved water.
Dr. Cassidy added that she did not know of a population in which diarrhea is not
bacteriologic.
Dr. Morris said that maybe one could do such a study in the U.S. or Canada, but that
there is a need for more animal studies. Dr. Shy said a randomized trial would take care of
the uncertainty of the baseline diarrhea level, and Dr. Backer replied that she could not locate
1000 babies in the U.S. to do such a study. Dr. Gomez asked if it is possible to lower sulfate
levels in areas where it is high. Irene Dooley responded that treatments such as reverse
osmosis and ion exchange are possible, but it could be costly to require that all public water
systems meet a level of 500 mg/L. Michael Baker, from the South Dakota Department of
Environment.and Natural Resources, Drinking Water Program, said that South Dakota did an
analysis of the water systems that exceed 500 mg/L and estimated that it would cost $60
million to lower the sulfate levels the 110 systems in the state to 500 mg/L. The average
household cost for public water in South Dakota is approximately $9 per month for water, but
would increase to approximately $28 per month to compensate for the cost of treatment to
remove'sulfate (reverse osmosis and ion exchange). South Dakota systems would likely chose
to convert to using surface water sources for drinking water rather than to remove sulfate
from ground water. Removing sulfate from drinking water would also be a financial burden
on the water treatment facilities. All but 27 systems with >_ 500 mg/L sulfate are in low-
income areas. The rest serve cloistered religious communities. Dr. Cassidy asked if there are
public health reports of increased physician visits in areas with high sulfate? Mr. Baker said
that his department did a non -scientific polling of 27 pediatricians and several family
Page 30

practitioners, and none reported ever treating diarrhea caused by exposure to sulfate.
Dr. Abernathy stated that the 1977 National Academy of Sciences (NAS) report
concluded that there are no adverse human health effects associated with exposure to 500
mg/L.sulfate or less, but EPA would need to study the data used to support that conclusion.
Dr. Cole asked Mr. Baker if there is a relationship between sulfate content and the
population's use of water for cooking, drinking, coffee, etc. Mr. Baker that sulfates come
from wells that are dug into the geologic formation called the Dakota Formation, and there
has always been an objection to the taste of this water; it makes terrible coffee. The levels of
dissolved solids are also high; however, before 1965, people used the water because they had
no choice. Using Rural Water Assistance grants, 39 systems switched to surface water for
aesthetic reasons. Now people can choose to purchase bottled water or install reverse
osmosis filtration systems in their homes. When Mr. Baker looked for health effects from
drinking water that contained high levels of sulfate, he found only one physician's assistant
who treated three youths from a combine crew who reported diarrhea after drinking
community water that contained 1,200 mg/L sulfate. However, these individuals were
drinking very large quantities of water (5 to 10 liters per day per person). Dr. Backer added
that in their infants sulfate study areas, people also used filters and bottled water for aesthetic
purposes.
Dr. Shy repeated that Dr. Abernathy's statement that by 2001 EPA must decide
whether or not to regulate sulfate, and asked whether EPA can regulate substances for
reasons other than health risk.. Dr. Abernathy said that EPA regulations can be based only on
the need to reduce the frequency of adverse health effects, but that States can issue
regulations for aesthetic reasons, such as taste.
Dr. Shy asked if there exists adequate scientific evidence that there are adverse health
effects associated with high levels of sulfate in drinking water. Dr. Abernathy asked whether
the workshop might consider making this question Issue 4. Dr. Backer wanted to know what
EPA's non -regulatory options are. Irene Dooley responded that if EPA decides not to
regulate the levels of sulfate in drinking water, EPA could keep the current secondary
guideline of 250 mg/L, which is based on taste and odor. EPA can also put out health
advisories or consumer advisories in localized areas.

Issue #4 Is there adequate scientific evidence that there are adverse health effects
from sulfate in drinking water to support regulation?
While there is not enough scientific evidence on which to base a
regulation, a health advisory in places that have sulfate levels of 500
mg/L or higher would acknowledge the needs of sensitive
subpopulations.
Dr. Shy briefly summarized the studies by Moore (1952), Heizer et al. (1997),
Esteban et al. (1997), and Gomez et al. (1995). The Moore (1952) study found a laxative
effect in water with high levels of sulfate. The Heizer et al. (1997) study found that adults
who ingested 1,200 mg/L sulfate had no diarrhea but reported increased stool bulk. Esteban
et al. (1997) found no increases in diarrhea in infants who ingested water containing up to
1350 mg/L sulfate, but the study had a small sample size and thus limited power to detect an
association. Gomez et al. (1995), found no effect in the frequency of diarrhea in piglets fed a
diet that contained 1,200 mg/L sulfate. Fifty percent of the piglets given 1,600-1,800 mg/L
sulfate had; however, the diarrhea did not affect weight of the piglets.
Dr. Cassidy wanted to know the range of sulfate levels currently found in tap water.
Dr. Abernathy said that surveys indicated about 3% of the tap water in the U.S. exceeds 250
mg/L, and levels up to 770 to 1,000 mg/L have been measured. For the 1994 proposal to
regulate sulfate, EPA estimated about 1965 public water supplies would exceed 500 mg/L.
Mr. Baker said that community systems in South Dakota may have sulfate levels as high as
1,350 mg/L, and some private wells are higher (up to 2,000 mg/L sulfate). Dr. Morris stated
that healthy adults would have no problem with 1500 mg/L. However, she cautioned that
mothers of infants, the elderly, and people with certain health problems may need to be
cautious when using for drinking water containing high levels of sulfate.
Dr. Abernathy informed the panelists that even if EPA decides that scientific evidence
cannot support issuing a federal regulation, states may still choose to regulate the amount of
sulfate in drinking water. Kim Harris, from EPA Region 5, told participants that if EPA
decides not to regulate sulfate, the potential health risks for susceptible populations will still
be addressed (e.g., with health advisories similar to those created for cryptosporidium).
Dr. Cassidy asked if there are surveillance or reporting data describing sulfate levels in
public water systems. Irene Dooley answered that there is a requirement to report sulfate
levels based on the unregulated contaminant monitoring requirements of 1992. EPA is in the
process of analyzing this data from the states. Dr. Cassidy asked if this data contains reports
of diarrhea or other adverse health effects. Dr. Backer responded that CDC and EPA are
developing a study to establish a national baseline for gastrointestinal illness. One challenge
associated with collecting this type of data is that when people have diarrhea, they usually go
to the drug store, not a doctor. Dr. Backer pointed out that monitoring the purchases of
over-the-counter medications in geographically defined areas can be an alternative approach
for evaluating localized gastrointestinal distress.
Dr. Shy directly asked the panelists if there is an answer to Issue 4. Dr. Cole answered
that there is nothing in the literature regarding effects in healthy adults from exposure to high
Page 32

levels of sulfate in drinking water, but that he believes that a health advisory would be in the
best interest for infants. He also said that an advisory for elderly people and for travelers
would be appropriate. Dr. Cassidy agreed with Dr. Cole that there is not enough scientific
evidence to indicate that exposure to high levels of sulfate causes adverse human health
effects.
Dr. Abernathy stated that EPA needs to specify a safe level, even in a health advisory.
He suggested that EPA could, for example, set a health advisory at 500 mg/L.
Dr. Morris answered that there is not enough evidence to support a health -based
regulation for sulfate levels for healthy adults. The populations of concern are infants, the
elderly, and people with health problems. Dr. Morris said that, in her opinion, information
from the available literature is that, 500 mg/L may be protective, but additional studies need to
be done to identify the appropriate concentration.
Dr. Gomez noted that special attention should be given to states that have a potential
problem. Ms. Tsuji added that it appears that while 3% of 200 million (6 million), people are
exposed, it is hard to find them, and we cannot be sure what else is in their water, so it may be
better to manage through pediatricians, the health department, and WIC clinics, and on an
individual level instead of trying to regulate at a national level. She noted that sulfate does
not cause irreversible damage, and that regulating other water contaminants is more urgent.
Mr. Baker gave his opinion that he is not in favor of regulating sulfate at this point, because
people are resolving the problem.
Dr. Shy summarized by saying no one study can provide a dose -response relationship
for sulfate, and that other studies are necessary. The existing literature supports issuing health
advisories, especially for infants, that sulfate levels > 500 mg/L may have negative health
effects. Dr. Cole reiterated his belief that it would not be possible to conduct an infant study
in the U.S. or Canada and that he does not believe the literature indicates acclimitization.
Krishna Parameswaran stated that his company has three mining sites in the west in areas with
sulfates in the drinking water, and the workers there do not experience diarrhea.

Sulfur Compounds
j
Sulfur compounds are very common in water. Sulfate ion, S042-, is found in
1
varying concentrations in practically all natural waters. Organic sulfur compounds,
both those of natural origin and pollutant species, are very common in natural
aquatic systems, and the degradation of these compounds is an important microbial
process. Sometimes the degradation products, such as odiferous and toxic 112S, cause
serious problems with water quality.
There is a strong analogy between sulfur in the environment and nitrogen in the
t
environment. Sulfur in living material is present primarily in its most reduced state,
for example, as the hydrosulfide group, -SH. Nitrogen in living material is present in
the (-III) oxidation state, for example, as -NH2. When organic sulfur compounds are
decomposed by bacteria, the initial sulfur product is generally the reduced form,
H2S. When organic nitrogen compounds are decomposed by microorganisms, the
reduced form of nitrogen, NH3 or NH4+, is produced. Just as some microorganisms
can produce elemental nitrogen from nitrogen compounds, some bacteria produce
and store elemental sulfur from sulfur compounds. In the presence of oxygen, some
E
bacteria convert reduced forms of sulfur to the oxidized form in S042- ion, whereas
(•
other bacteria catalyze the oxidation of reduced nitrogen compounds to nitrate ion.
{;
Oxidation of H2S and Reduction of Sulfate by Bacteria
Although organic sulfur compounds often are the source of H2S in water, they
are not required as the sulfur source for H2S formation. The bacteria Desulfovibrio
can reduce sulfate ion to H2S. In so doing, they utilize sulfate as an electron acceptor
in the oxidation of organic matter. The overall reaction for the microbially-mediated
s;..
oxidation of biomass with sulfate is,
f.
SO42- + 2{CH2O} + 2H+ - 112S + 2CO2 + 2112O (6.12.3)
:
and it requires other bacteria besides Desulfovibrio to oxidize organic matter
j
completely to CO2. The oxidation of organic matter by Desulfovibrio generally. ter-
minates with acetic acid, and accumulation of acetic acid is evident in bottom
waters. Because of the high concentration of sulfate ion in seawater, bacterially -
mediated formation of H2S causes pollution problems in some coastal areas and is a
major source of atmospheric sulfur. In waters where sulfide formation occurs, the
sediment is often black in color due to the formation of FeS.;-

Aquatic Microbial Biochemistry 175
Bacterially -mediated reduction of sulfur in calcium sulfate deposits produces
elemental sulfur interspersed in the pores of the limestone product. The highly
generalized chemical reaction for this process is
k'. 2CaSO4 + 3 { CH2O}• Bacteria 2CaCO3 + 2S + COZ + 3H2O (6.12.4)
although the stoichiometric amount of free sulfur is never found in these deposits
due to the formation of volatile H2S, which escapes.
Whereas some bacteria can reduce sulfate ion to 112S, others can oxidize hydro-
gen sulfide to higher oxidation states. The purple sulfur bacteria and green sulfur
bacteria derive energy for their metabolic processes through the oxidation of 112S.
These bacteria utilize CO2 as a carbon source and are strictly anaerobic. The aerobic
colorless sulfur bacteria may use molecular oxygen to oxidize H2S,
2112S + 02 -� 2S + 2112O (6.12.5)
elemental sulfur,
2S + 2112O + 302 -� 4H+ + 2SO42- (6.12.6)
or thiosulfate ion:
S2032- + H2O + 202 -� 211+ + 2SO42- (6.12.7)
Oxidation of sulfur in a low oxidation state to sulfate ion produces sulfuric acid,
a strong acid. One of the colorless sulfur bacteria, Thiobacillus thiooxidans is
tolerant of 1 normal acid solutions, a remarkable acid tolerance. When elemental
sulfur is added to excessively alkaline soils, the acidity is increased because of a
microorganism -mediated reaction (6.12.6), which produces sulfuric acid. Elemental
sulfur may be deposited as granules in the cells of purple sulfur bacteria and
colorless sulfur bacteria. Such processes are important sources of elemental sulfur
deposits.
Microorganism -Mediated Degradation of Organic Sulfur
Compounds
Sulfur occurs in many types of biological compounds. As a consequence,
organic sulfur compounds of natural and pollutant origin are very common in water.
The degradation of these compounds is an important microbial process having a
strong effect upon water quality.
Among some of the common sulfur -containing functional. groups found in
aquatic organics compounds are hydrosulfide (-SH), disulfide S-SS-), sulfide (-S-),
sulfoxide (—S— ), sulfonic acid (-SO20H), thioketone (—C— ), and thiazole (a
heterocyclic sulfur group). Protein contains some amino acids with sulfur functional
groups—cysteine, cystine, and methionine—whose breakdown is important in
natural waters. The amino acids are readily degraded by bacteria and fungi.

Well Water Sample Results
House Well, 410 Cornelius Road, Rockwell
Rowan County, N.C.
Dear Mr. House:
I am enclosing a copy of a Health Risk Evaluation performed by Dr. Ken Rudo based on the latest
sampling results from your well in Rowan County. Dr. Rudo has indicated that the water should be considered
safe for normal usage. He indicated that iron levels may be an aesthetic problem, but not an increased health
risk. He further recommends a VOC, SVOC, and pesticide test. Though I am not currently aware of any
nearby contamination associated with VOC, SVOC, or pesticides, based'on his recommendation I am willing to
sample your well for those constituents. Please contact me if you would like arrange for those samples to be
collected.
Should you have any questions, please do not hesitate to contact Dr. Rudo at [phone] or me at
[phone].
Sincerely,
Andrew H. Pitner, P.G.

RE: Well Water Sample Results
House Well, 410 Cornelius Road, Rockwell
Rowan County, N.C.
Dear Mr. House:
On March 27, 2007, 1 resampled your water supply well at 410 Cornelius Road in Rockwell in Rowan
County. The samples were analyzed by the Division of Water Quality (DWQ) Laboratory for a variety of
inorganics including aluminum, as well as for sulfate, volatile organics, semi -volatile organics, and pesticides.
A copy of the complete laboratory results is enclosed for your review and I have summarized the results
for selected constituents, among the wide range of those tested for, on the following table along with standards
and previous sample results for comparison. Please note that some values are recorded in µg/L (pails per
billion) and others are recorded in mg/L (parts per million) and that no volatile organics, semi -volatile organics
and pesticides were detected.

Based on the sample results from these two sampling events, aluminum has not been detected in your well
water. The detected concentration of sulfate is below the referenced EPA and North Carolina standards. As
you may be aware, sulfate can be naturally occurring in groundwater and this concentration is not unusual for
Rowan County samples. The March 27 sample's concentration of iron is above the referenced standards and
significantly higher than the January 17 sample. This variability may be due to some turbidity in the water,
which was present during the March 27 sampling event. The turbidity might be associated with the age,
maintenance, or use of the well or perhaps a construction problem that allows some sediment into the well
bore. Sample preservation of raw water can leach metals such as iron from the tiny particles that cause the
water to appear turbid.
As mentioned in our recent email exchanges, I have forwarded a copy of your analytical results to Ken
Rudo, the State Toxicologist, and requested a written health risk evaluation for human consumption. I will
forward the results of his evaluation to you upon receipt.

You have indicated that you are not confident in these analytical results and I encourage you to explore
sending your own samples to an independent certified laboratory for drinking water analysis. The DHHS Lab
Certification Office can be reached at [phone] and a list of labs is available on the internet at
iltt:/�sltDii.Stpte.nc.i_isr/F-nyironi-n.entalSrlencC'ulC,--r if!Cat;lon/Cer iiiedL.,,-ibora-tor�/ asp.
At this point after two sampling events, there is still not sufficient information for me to conclude that
Alchem is responsible for any of the detected constituents in your well. You well may be in need of
maintenance, such as disinfection/chlorination, and, if the turbidity does not clear with more frequent use,
perhaps a sediment filter or installation of a liner. If you have not done so recently, I encourage you to test the
well for bacteria by contacting a private lab or Rowan County Environmental Health.
Should you have any questions, please contact me at [phone] extension 2180 or by email at

RE: Well Water Sample Results
House Well, 410. Cornelius Road, Rockwell
Rowan County, N.C.
Dear Mr. House:
On January 17, 2007, 1 sampled your water supply well at 410 Cornelius Road in Rockwell in Rowan
County. The samples were analyzed by the Division of Water Quality (DWQ) Laboratory for a variety of
inorganics including aluminum.
A copy of the laboratory results is enclosed for your review and I have summarized the results for
aluminum and detected constituents on the following table along with standards and commonly found values
from two datasets for comparison. Please note that some values are recorded in µg/L (parts per billion) and
others are recorded in mg/L (parts per million).

The EPA Primary and Secondary Standards are applicable to public water supply systems, such -as Salisbury -
Rowan Utilities, which serves much of Rockwell. The NC Groundwater Quality Standards are health -based
values that represent the maximum allowable concentrations in groundwater resulting from discharges of
contaminants — these would apply to discharges to groundwater by Alchem. The Department of Health and
Human Services (DHHS) Laboratory values for Rowan County were generated from a dataset of 221 samples
collected from late 1998 through mid 2004 that represent levels from raw, untreated groundwater from across
the county. The DWQ MRO Metals Study Database reflects raw untreated groundwater samples collected at
fifty (presumably uncontaminated) locations across the Mooresville Region, which includes six samples from
Rowan County.

As shown in the table, the results from your well are below EPA Drinking Water Standards and
enforceable NC Groundwater Quality Standards. However, your results also appear to have higher than
median values from comparable datasets for calcium, iron, magnesium, manganese, and zinc. Though not
presented in the table, ranges from those datasets for all constituents are typically from below detection limits
to above EPA and/or NC standards (i.e. your results fall within the range of values commonly seen). Based on
my experience, it is not uncommon to find naturally occurring elevated levels of these inorganic substances in
groundwater, particularly for iron and manganese, though levels can also be affected by the age and
maintenance history of the well, the well casing material and associated piping and fixtures. I will forward a
copy of your analytical results to the State Toxicologist and request a written health risk evaluation for human
consumption. I will forward the results of their evaluation to you upon receipt.
For your information, data readily available to me regarding sampling of wells at Alchem indicates that
aluminum was detected in their supply well (likely constructed into bedrock similar to your well) at levels
varying levels ranging from below detection limits to 522 µg/L with an average value of 86 µg/L from 1993 to
2001. The two monitoring wells currently at the site are shallow wells screened across the top of the water
table (a construction design intended to more rapidly detect any groundwater impacts from surface activities).
The closest monitoring well to your property, MW-1, presumed to be hydraulically upgradient at the facility, has
also shown variable levels of aluminum since 2002 ranging from below detection limits to 910 µg/L with an
average of 280 µg/L. MW-2 is located in an area presumed to be hydraulically downgradient of their process
site and lagoons and it has consistently detected aluminum since 2002 ranging from 137 µg/L to 4,760 µg/L
with a marked upward trend since 2005, likely indicating that the lagoons are impacting groundwater quality.
Alchem has been issued notices of violation associated with this problem and others at their facility in regards
to permits that they hold. Based on the sampling results from your well, applicable enforceable standards,
and groundwater data from the Alchem site, there is not sufficient information at this time for me to conclude
that Alchem is responsible for any of the detected constituents in your well.
If ,you wish to discuss the analytical methods used in the analysis of your sample, you may contact Roy
Byrd, Inorganic Chemistry Branch Manager, at the DWQ Lab at [phone]. Should you desire to have
additional samples analyzed by other labs, I suggest that you make contact with a private lab certified for
drinking water analysis. Though more costly, they will also be able to have the quickest turnaround time on
samples. The DHHS Lab Certification Office can be reached at [phone] and a list of labs is available
on the internet at http://slph.state.nc.us/EnvironmentaISciences/Certification/Certified Laboratory.asp. You may
also contact the.Rowan County Health Department, which sends samples to the DHHS Lab, at [phone]
and will charge a small fee for the sampling.

FROM: Andrew Pitner c -1
SUBJECT: Request for Health Risk Evaluation
for Well Sampling Results:
H House — AB 12512
Ken,
Staff of the Mooresville Regional Office requests that health risk evaluations
for sampling results from this water supply well be completed and sent to our Office.
Your evaluation will be sent to the well owner by the MRO.
- Please note that the well owner has voiced concerns about use of this
water on his health due to proximity to a facility that processes bauxite
(aluminum ore). Should you wish to discuss this with Mr. House, he can be
reached at [phone]
If you have questions or need additional information, please contact me at

Hi Andrew,
Mr. House in Rowan County called me about the Al result for sample AB12512. He
seemed convinced that Al in his water, even though we did not detect any (50U). We
had not discarded the sample, so I had it re -analyzed yesterday and aluminum was
not detected (actual number was 16 ug/L). Also, we did a matrix spike (added a
known amount of Al to the sample) to check for interference and and got a 990
recovery, which indicated no interferents were in the sample. I gave him that
information this morning and I think convince him, some what. The problem is that
he is taking his water sample, adding Na OH and warming it to get a precipitate,
which he is assuming is Al sulfate. The chemistry is exactly opposite, you would
have to acidify the sample to get Al sulfate. I have no idea what he is getting,
but Bill Skinner is going to try to duplicate that with the remaining sample.
Anyway, we will run another sample for metals if you would like to collect
another. Also, we'll do a sulfate if you would like.
Sincerely,
Roy Byrd
