Dear Mr. Erickson,
As of this date, our records indicate that the above referenced permit, which was issued on May 31, 1996 and
expired on April 30, 2001, has not been renewed. You also have not responded to the letter mailed to you on December 7,
2004 requesting permit renewal. It is both a condition of your permit and required by 15A NCAC 21-1.0211 to request a
renewal of your permit at least 180 calendar days prior to its expiration date. Failure to apply for pemut renewal, and
continued operation of your facility without an active permit may result in an enforcement action by the Division, in
accordance with North Carolina General Statute 143-215.6A to 143-215.6C. Therefore, it is imperative that you submit a
permit renewal application for review as soon as possible.
Although the Underground Storage Tank (UST) Section may have informed you that groundwater remediation is
temporarily not being directed at your facility due to Session Law 2004-124, you are still required to submit either a
permit rescission request or a permit renewal application to the Aquifer Protection Section (APS). To comply with the
permit requirements set forth in your permit and 2H .0211, the APS is making the following options available to you:
1. Permit Renewal. When you apply for and receive a renewal, operation of the groundwater
remediation system will be permitted to continue. As such, annual fees, all requirements for sampling
and annual reports, and any operation and maintenance specified in your previous permit will be
required.
2.
Pen -nit Renewal with Suspended Actions. Under this option, you must still apply for a permit
renewal. However, you may indicate that operation of the remediation system has been suspended,
but you desire to maintain the permit should the need arise to restart the system. As such, operation
of the remediation system will be prohibited until such time that a permit modification is obtained
from the Division allowing operation of the system. Under the "Permit Renewal with Suspended
Actions" option, all monitoring and annual reports will be suspended until otherwise notified.
Infiltration galleries will be directed to be winterized as a permit condition, as well as temporary
abandonment of any monitoring wells in accordance with 15A NCAC 2C .0113(a). Annual fees will
still be required, but may be reimbursed under the NC State Trust Fund as a directed cost. This
option allows you to keep your system inactive until remediation is once again directed by the UST
Section. At that point, you will need to request a modification to your permit to activate your system.

Dear Mr. Bolton:
��Wai�R �E��10N
Nc,
Jack Floyd and I met on August 5, 1992, to discuss the Texfi Industries (Texfi)
Non -discharge Permit modification. Two modifications have been proposed for this
permit: (1) eliminating the metals treatment system and (2) reducing the number of
recovery wells.
Metals Treatment System
It is my understanding that Mr. Floyd concurs with eliminating the metals treatment
system provided the zinc and nickel concentrations in the effluent are monitored on a
regular basis.
Reducing the Number of Extraction Wells
Based on the pumping test data, Mr. Floyd concurs with reducing the number of
extraction wells. If a sufficient capture zone is not developed, the number of
extraction wells would be increased. Mr. Floyd has expressed concern about whether
the infiltration trench is located in the capture zone of the recovery system (i.e.,
forms a closed -loop system). Based on the water level data collected since 1988, it
appears that the infiltration trench is located hydraulically upgradient from the
recovery well system, which does create a closed -loop system.
To determine whether the infiltration trench is within the recovery well system's zone
of influence, we discussed measuring water levels in all on -site monitoring wells
monthly to develop a data base of these measurements. I suggest incorporating six
monthly water level measurements into the permit modification .
As requested by Mr. Floyd, a map illustrating the locations of the recovery wells
relative to the infiltration trench is enclosed. A map showing the capture zone will be
generated and submitted to DEM once the ground water remediation system
OPT operational and the data ids obtained.

Desire to Initiate Remediation
I want to reemphasize Texfi's desire to resolve this matter. As you are aware, Texfi
cannot initiate ground water remediation until approval is granted for the March 3,
1992, permit modification request. The ground water remediation system without
the metals treatment system was installed in April in accordance with Non -Discharge
Permit No. W00004936; however, no remediation has been permitted to occur
during the past 5 months. In addition, failure to initiate the restoration of the
impacted ground water may result in contaminant plume migration. Texfi has been
very willing to comply with the remediation program your agency has required and
cannot understand the lengthy delay in allowing them to fulfill this request.
Your help in resolving this issue will be greatly appreciated. If you have any
questions, please call us at [phone].
Sincerely,

Groundwater Remediation System
Craven County
WQ0004936/GW92127
Dana Bolden : Review Engineer
The Groundwater Section has reviewed the subject modification
request to abandon most of the recovery wells and eliminate the use of
the metals recovery device. The original permit was issued September
23, 1991 for a 60 GPM groundwater remediation system. Since the
initial site assessment the consultant has concluded that the eleven
recovery wells are unnecessary. Capture zones for the five remaining
recovery wells are adequate for remediation purposes. The metals
concentrations were never found in such great quantities as to require
removal before reinfiltration.
Therefore, the' Groundwater Section recamends that the permit be
modified to:
1) Abandon all wells except RW-4a, RW-7a, RW-8, RW-10a, and
RW-11, and
2) Eliminate the metals treatment unit.
These recommendations are contingent upon inclusion of the
following conditions:
1) All components of the groundwater recovery, treatment and
disposal system shall be properly weather -proofed to prevent
freezing and failure of the system.
2) The groundwater recovery, treatment and disposal system shall
be inspected weekly. If it is determined that the system is
malfunctioning, all repairs should be made as soon as
possible and reported to the Regional Office.

3) The influent and effluent from the treatment system shall be
sampled once every two (2) weeks for the first three (3)
mcnths and quarterly thereafter for the parameters specified
below:
Volatile Organic Compounds - by Method 1 or
Method 2 below
Method 1: Method 6230D (Capillary - Column),

Method 2: Method 502.2 "Methods for the
Determination Organic Ccmpounds in
Drinking Water", United States
Environmental Protection Agency
- 600/4-88/039
4) The influent of the system shall be sampled quarterly for the
following parameters:
Total Nickel
Total Zinc
5) The results of the sampling and analysis shall be sent to the
Groundwater Section in the Washington Regional Office and to
the Groundwater Section, Permits Unit, Post Office Box 27687,
Raleigh, North Carolina 27611-7687 within 30 days of sample
collection.
6) After data has been collected for one full year, the
permittee may request a reduction in the above monitoring
requiremdnts.
7) The permittee shall submit a detailed map depicting the
capture zone of each recovery well within 1 year of permit
issuance and submit it to the Groundwater Section.
If there are any questions please let me know.

The Groundwater Section has conducted a preliminary review of the subject application, and
cannot recommend issuence of the permit admendment without the following information and/or
clarification:
(1) Cross -sections of the surficial aquifer and Castle Haynes aquifer formations, showing
recovery and monitoring well screens, in addition to the static groundwater levels
in both aquifers and the contaminant contours in both aquifers.
(2) Plan view maps of the contaminant contours in both surficial aquifer and Castle Haynes
aquifer.
(3) A comparison of chemical analyses from (a) the surficial aquifer influent water, (b) the
deeper Castle Haynes aquifer influent water, and (c) the effluent of the treatment system.
This chemical analysis comparison should include all organic/inorganic contaminants, in
addition to what would be considered a normal water quality suite of constituents (TDS,
pH, chloride, manganese, iron, etc.). The purpose of this comparison is to verify that after
the surficial waters and Castle Haynes waters have been treated and mixed, the effluent
water quality injected back into the Castle Haynes aquifer does not degrade the natural
water quality of the Castle Haynes aquifer. This anaysis should consider not only the
organic contaminants, but also the natural water quality difference between the two
aquifers. For example, if the surfical aquifer is high in iron, but the Castle Haynes aquifer
is low in iron, then the injection will degrade the Castle Haynes quality with regards to
iron.

(3) From the above chemical analysis, if the Castle Haynes aquifer is determined to be
degraded sufficiently, then it may be necessary to separate the surficial water treatment
system from the Castle Haynes water treatment system.
(4) An analysis of the chemical components/products to be expected in the effluent from the
addition of acetic/hydroxyacetic acid to the wastestream.

SUBJECT: Non -Discharge Permit Amendment
Texfi Industries, Inc. - New Bern Facility
Groundwater Remediation System - Craven Co.
WQ0004936 GW95214
n
i
The Washington Regional Office has reviewed the subject
amendment request. Based on our review, the following comments are
submitted for your consideration:
1. Although the applicant indicates in Section IV - DESIGN
INFORMATION FOR INJECTION WELLS, that the injection well will
discharge into the same aquifer from which the contaminated
groundwater was extracted, a review of the design plans indicates
that groundwater recovery wells RW-4, RW-7, and RW-10 are screened
in the shallow Yorktown formation surficial aquifer system, and
that only recovery well RW-11 is screened in the confined/semi-
confined Castle Hayne Aquifer. Since the proposed injection well
will be screened only in the Castle Hayne Aquifer, it appears that
some of the treated shallow groundwater will be discharged into the
Castle Hayne Aquifer. Our office is concerned that malfunctions in
the treatment system due to equipment failures and/or undiscovered
"slugs" of contaminated surficial groundwater that exceed the
treatment capacity of the two (2) air strippers could result in
further contamination of the Castle Hayne Aquifer.
2. Due to the relatively high iron concentration in the groundwater
in this area, which quickly clogs up granulated carbon filtration
systems, the existing treatment (air strippers) does not include
carbon filtration prior to injection. Carbon Filtration also
provides a "safety factor" in that it removes any contaminants that
are not removed by the air strippers. While we understand the
economic rational for not providing carbon filtration, we are
concerned that any contaminants that are not removed by the air
strippers (see comment No. 1 above) will be injected into the
Castle Hayne Aquifer.

Memo to Ken Pohlig
Texfi Industries, Inc.
October 31, 1995
Page Two
3. The plans indicate that the groundwater recovered from the
Castle Hayne Aquifer (recovery well RW-11) AND the groundwater
recovered from the shallow groundwater recovery wells (RW-4, RW-7,
and RW-10), minus the roughly 2 gpm that will be combined with the
groundwater recovered from RW-8 (roughly 10 gpm) and disposed of
via the existing infiltration gallery, will be injected into the
Castle Hayne Aquifer. Although the applicant states in Section 2.3
of the permit application that "Complete capture was shown to occur
at a recovery rate of 30 gpm (see Appendix C), while the recharge
rate remained at 50 gpm.", we do not understand how a system that
injects more groundwater into the Castle Hayne Aquifer than is
recovered from the Castle Hayne Aquifer can function as a "closed
loop system". Further clarification is needed in this area.
4. The applicant indicates in Section 3.2 that bacterial and
chemical precipitates have hindered the operation of the existing
remediation system, and proposes to treat the recovery wells and
the injection well with hydroxyacetic acid on a periodic basis.
While we do not necessarily object to this proposal, the applicant
should provide additional discussion of: a) how the "mixture"
recovered from the wells after treatment will be neutralized, and;
b) what effects, if any, will the mixture (including minerals
dissolved by the acid) have on the treatment system, the injection
well, and the Castle Hayne Aquifer.
In closing, we are not prepared to recommend approval of the
amendment request at this time. Upon receipt of additional
information addressing the above concerns, our office will re-
evaluate this proposal and inform you of our position by memo. If
you have any questions, or wish to discuss this matter further,
please contact me at any time.

2. The existing permit only requires quarterly influent/effluent
sampling, and does not specify the number of monitoring wells
that should be sampled or sampling frequency. Although there are
as many as twenty-eight (28) wells (both recovery and monitoring)
at the site, several of the wells are not usable because their
shallow depth results in the wells being dry for extended periods.
In addition, several wells are either located upgradient of the
plume, or are in close proximity to other monitoring wells, and are
not really needed to monitor system performance. We recommend the
new permit require semi-annual sampling of the following wells: MW-
3 (upgradient), MW-4, MW-10a, MW-11, MW-12, MW-13, MW-14, RW-4a,
RW-7a, RW-8, RW-10 and RW-11. Analysis should be by EPA Method
6230D or Method 502.2 (as required in the current permit). I have
attached a site map showing the locations of all the wells with
circles around the wells we suggest be sampled.
If you have any questions, or wish to discuss this matter
further, please contact me at any time.

Aquaterra Job No. 4101003
Dear Mr. Morey:
Aquaterra, Inc. (Aquaterra) is assembling a request to modify Texfi Industries'
existing Non -discharge Permit to include an injection well. As part of the permit
modification package, Aquaterra is addressing the maintenance aspect of the
proposed injection well and the existing recovery wells. We would like to determine
the Division of Environmental Management's position on the chemical treatment of
wells prior to the submission of the permit modification package.
It is our understanding that the use of hydrochloric acid and sodium hypochlorite
solutions are allowed. However, the resulting formation of chloroform is an issue of
concern. Based on the enclosed references, Aquaterra would like to propose
treating the wells with an organic acid (i.e., hydroxyacetic acid (CH2OHCO&I) or
acetic acid (CH3CO2H)) to remove the chemical and biological precipitates from
the well.
The advantages for using an organic acid as compared to a chlorinated solution are
toxic compounds are less likely to form,
iron and manganese deposits are chelated, and
safer to use.

Specifically, the proposed treatment program consists of adding 1 gallon of
70 percent hydroxyacetic acid per 10 to 15 gallons of water standing in the well. The
mixture will be agitated in the well with a surge block every 2 hours for 8 hours. The
material will be purged from the wells and transferred to the treatment system for
neutralization, and the process will be repeated.
We look forward to receiving your reply. If you have any questions or need
additional information, please contact us at [phone].
Sincerely,

Welly (20 percent of the weight of the acid) to create a solution that will treat iron
and manganese incrustants.
Sulfamic acid reacts chemically with mineral deposits in the same manner as hy-
drochloric acid, although at a slower rate. Consequently, longer contact time is usually
required to achieve the same results; at least 15 hours is recommended. The effec-
tiveness of the treatment is enhanced considerably if the acid is agitated while and
immediately after it dissolves. Forceful agitation is also recommended before the acid
is pumped to waste.
Sulfamic acid should not be confused with sulfuric acid. Sulfuric is a strong liquid
acid that has been used successfully on rare occasions in well treatment. Its major
limitation in well treatment is that when it combines chemically with calcium scale,
it forms calcium sulfate which is nearly insoluble in water. Thus, a sulfuric acid
treatment may actually reduce the well's performance. In addition, sulfuric acid, even
when inhibited, is extremely aggressive in attacking metallic casing and screens.
Hydroxyacetic Acid
Hydroxyacetic acid, also known as glycolic acid, is a liquid organic acid available
commercially in 70-percent concentrations. Although not as well known or commonly
used as either hydrochloric or sulfamic acid, its use has achieved excellent results in
well treatment. It is quite safe to use because it is relatively noncorrosive and produces
little or no toxic fumes.
In addition to its ability to dissolve mineral scale, hydroxyacetic acid offers ad-
vantages not available with sulfamic or hydrochloric acid. It is an excellent bactericide
and therefore may be effective in treating wells with iron bacteria problems. It kills

the bacteria and simultaneously dissolves the bacterial iron deposits as well as other
mineral scale.
In addition to its bactericidal properties, hydroxyacetic acid is a chelating or se-
questering agent. This means that it has the ability to "surround" metal ions (such
as iron, calcium, and magnesium) in solution and keep them from combining chem-
ically with other ions. This insures that all the scale dissolved by the acid remains in
solution during the entire treatment period.
Hydroxyacetic acid is placed in the well in the same manner as hydrochloric acid.
About 1 gal (3.8 t) of 70-percent hydroxyacetic should be used for every 10 to 15 gal
(38 to 56.7 t) of water standing in the well screen. Table 19.4 shows the proper amount
of hydroxyacetic acid to use in treating wells of various diameters.
Hydroxyacetic acid is weaker than both hydrochloric and sulfamic acid, and longer
contact time is required to achieve the same amount of scale removal. The rate at
which an acid removes scale is related to the acid's pH (acid strength). Figure 19.3
shows how pH varies with concentration for the acids described above. Note that
hydrochloric acid has the lowest pH and thus will work the fastest, whereas hydrox-
yacetic has the highest pH and will work more slowly than the other acids.
General Procedure for Acid Treatment
Great care should be taken in placing liquid acid into a well. Only experienced
personnel with specialized equipment should attempt to use it in rehabilitating a well.

Figure 19.3. Equal concentrations of different acids
form solutions with different pH values; pH of an
acid -water solution varies with concentration.
When using any liquid acid, personnel
should wear protective rubber clothing
and goggles. A breathing respirator
should also be used by all personnel han-
dling the acid and by other persons near
the well. All mixing tanks, chemical
pumps, and piping (tremie pipes) should
be constructed of plastic or black iron to
minimize reaction to the acid. A large
quantity of water, or a water tank with a
mixture of sodium bicarbonate, should be
available in the event that an accident oc-
curs. Proper ventilation must be main-
tained because the fumes released from
the well during treatment are lethal.
Liquid acid should be introduced into
the well through a small -diameter pipe. If
the screen is more than 5 ft (1.5 m) long,
enough acid should be added to fill the
lower 5 ft of screen. Then the pipe should
be raised and the next 5 ft of screen filled
with acid, continuing in this way until the
entire screen is full. Pelletized forms of
sulfamic acid dropped into the casing will
accumulate in the screen where the pellets
dissolve. When the granular forms are

WELL AND PUMP MAINTENANCE AND REHABILITATION 643
poured into the casing, they go into solution throughout the entire column of water
in the well.
After the acid is placed in the well (or the pellets dissolve), a volume of water equal
to that standing in the well screen is poured into the well to force the acid solution
through the screen -slot openings into the formation. Some form of mechanical agi-
tation, such as surging, should be employed while the acid is in the well to help break
up the incrustation and improve the overall efficiency of the process. This step is
particularly important because it exposes the incrustant to the acid, thereby assuring
maximum removal.
The use of surge blocks or jetting tools are effective methods of agitating the well.
The agitation time will depend on the amount of incrustant in the well. If a surge
block is used, the surging effect drives the acid into the formation and brings loosened
material into the screen. In the jetting operation, the acid is first poured into the well.
The screen or the face of the well bore can then be jetted with clean water from the
surface or acidized water from the well (Figure 19.4). A pump pressure of 100 to 250
psi (690 to 1,720 kPa) is sufficient for this type of operation. Circulation of the acid
solution may be corrosive to the jetting
pump and other equipment, but the wide
use of plastic impellers has eliminated
most of this type of corrosion damage. If
the job requires recirculating the jetting
acid at the surface, it is best to call on a
' well servicing company that has special-
ized equipment for this work. Great care
should always be exercised whenever acid
is being pumped in any well rehabilita-
tion operation.
An extended zone of the formation
around the well screen may be wholly or
partially clogged. Thus, it must never be
assumed that the chemical solution
moves uniformly outward into the voids
of the water -bearing materials in all di-
rections throughout the full thickness of
the formation. The chemical solutions
will now most readily into those areas
where the formation or screen is the most
open, that is, where resistance to flow is
the least. Therefore, it may be extremely
difficult and even impossible to diffuse
the chemical solution to all points where
it can dissolve or otherwise remove the
unwanted deposits.
The use of chelating agents is recom-
mended if iron and manganese incrus-
tants are present and the pH of the treat-
ment solution is approximately 3 or less.
Figure 19.4. To avoid the dangerous practice of
pumping acid at the surface, jetting can be accom-
plished by setting a pump in the well and using the
acidified water in the borehole.

644 GROUNDWATER AND WELLS
At this pH, these cations form insoluble precipitates that settle out and reduce the
effectiveness of the acid treatment. Citric, phosphoric, and tartaric acids are three
common chelating agents. Four pounds (1.8 kg) of chelating agent are usually added
to each gal (3.8 t) of 31-percent (20 degrees Baum6) hydrochloric acid and 1 lb (0.5
kg) of chelating agent to 15 lbs (6.8 kg) of sulfamic (granular) acid.
After mechanical agitation, the solution is left in the well to react with the incrusting
materials until the pH is between 6.5 and 7, then agitated again and pumped to
waste. The time for the reaction to be completed will vary from a few hours to more
than 15 hours, depending on the type of acid used and the amount of incrustants. To
minimize disposal problems, the water in the well should be neutralized if necessary
before it is removed from the well. In many communities, the water well contractor
may be required to haul away the spent acid and dispose of it according to local
regulatory agencies. If not, the spent acid should be run onto a sandy section of ground
as far away as practicable from the well head. Some contractors neutralize acid waste-
water by running it through a limestone -filled container.
Many water well contractors will redevelop the well after it has been acid treated.
Solid particles of incrustant can be removed along with any fine sediments that may
have entered the zone immediately around the screen after the well was placed in
service. In many instances, effective redevelopment of an older, acid -treated well will
result in a specific capacity that equals or even exceeds the original specific capacity.
The various development procedures are discussed in Chapter 15.
Mechanical Methods to Remove Incrustants
Although removal of most incrustants by acid treatment is extremely effective,
several mechanical methods are useful either in preparing for acid treatment or as a
primary method of removing incrustants. Wire brushing or other means of mechanical
scraping can remove incrustants that have been deposited on the inside of the well
screen. The loosened material is then removed from the well by bailing, air-lift pump-
ing, or other means. Removal of these incrustants minimizes the quantity of acid
that must be used in any subsequent acid treatment, enhances the effectiveness of
this treatment, and reduces the time required for the acidizing process.
Controlled blasting techniques are often useful for temporarily improving well yield
by fracturing the incrusting matrix so that water can reach the screen. Incrusting
materials are sometimes deposited on formation materials several inches or more
away from the screen. The incrustant may become so massive that all voids in the
formation become filled and little water can reach the screen. Blasting procedures
create cracks in the incrustant, allowing water to enter the well. Some fragments of
the incrustant will break away and can be pumped from the well. Unfortunately, the
opened cracks eventually will also become incrusted and additional blasting or acid-
izing treatments will be needed to maintain yield. This technique, when combined
with acidizing, is particularly effective. Special service companies have formed to
provide this type of blasting service.
Incrustation of Rock Wells
Although this discussion has referred only to screened wells in unconsolidated
formations, wells in consolidated rock also suffer from incrustation of the borehole
wall or the cracks and fissures leading to the borehole. Many rock wells require

logs (gamma, resistivity, spontaneous potential, or others) from the
time of construction are not available, they can be obtained from
information collected at this time. Utilizing logging techniques,
casing and grouting problems, screen location, permeable zones, and
other pertinent information necessary for the proper application of
maintenance, procedures can be identified.
A closed-circuit television or photographic survey of the well after
the pump is removed is often the most reliable means of obtaining
specific information concerning the condition of the well. Both of
these techniques have been successfully used in evaluating well
condition8, and both produce clear pictures that identify specific
problems. Television and photographic surveys can pinpoint the
exact location of casing problems, screen blockage or failure, and the
location and nature of production zones in rock wells. When screens
or zones are heavily incrusted, the television camera can help obtain
a sample of the incrusting materials while performing the inspection.
A sample can be taken by lowering a small bucket -shaped container
ahead of the camera to scrape off a portion of the material in
question. These samples can then be analyzed, and the results can be
used to select the appropriate chemical treatment.
CHEMICAL TREATMENT The purposes of chemical treatment are
diverse, but the objectives are usually to dissolve incrusting inorganic
deposits from screens, pore spaces of the aquifer adjacent to the
screens, and other areas that affect well performance. Most frequently
these deposits are calcium, magnesium, or iron carbonates, oxides,
hydroxides and occasionally sulfates.
Certain chemicals act as biocides, killing bacteria present in the
well and aquifer and dissolving their gelatinous remains in order to
release and remove inorganic materials. Still other chemicals disperse
fine materials, such as clay and silt, maintaining them in suspension
until they can be removed from the well.
Three classes of chemicals are commonly used in well mainten-
ance procedures: acids, biocides and phosphates. Table 3.1.3 sum-
marizes some of the more commonly used chemicals, along with
their significance and utility.
CHELATION, WETTING AGENTS AND INHIBITORS An important
attribute of some chemicals —including hydroxyacetic acid, citric
acid, mixtures of these and similar chemicals —is theirability to form
soluble complexes with iron. This prevents iron from redepositing
during the latter stages of chemical treatment. This process is

termed chelation.
Iron is commonly present in ground water in the soluble ferrous
(Fe+z) state. Foranyofseveral reasons, iron maybe present not only in
solution, but in a colloid form, precipitated in the ferric (Fe+3) state
(insoluble) or hydrolized as insoluble hydrated ferric oxide. Thus the
chelation process is indispensible to the removal of iron from any
well troubled by iron -related deposits.
Wettingagents act to reduce the natural surface tension ofwater.
This surface tension is the result of the weak forces that attract
molecules of water to each other. By adding a wetting agent, these
weak molecular bonds are broken. By doing this, it is possible to
increase the penetration ofchernicals into theaquifer, improving the
impact of the chemical treatment.
Corrosion inhibitors are employed with many strong acids in
order to optimize their cleaning capability. The acids dissolve scales
that plug screens and pore spaces. The inhibitors are specifically
designed to "inhibit" the activity of the chemical being applied with
regard to certain materials and to selectively permit the maximum
dissolution of other materials.
SURFACTANTS/POLYPHOSPHATETRF.ATMENT Somechemicals,
rather than dissolving, precipitating or chelating have the capacity
to attach themselves to the small particles of clay, colloids, and even
some ionic metals such as iron. This causes all of the resulting
complex particles to have the same ionic electrical charge. Similar
electrical charges repel each other, therefore, there is a strong impetus
for large particles to break up into small ones, with the dispersed
smaller particles being easy to pump from the well. Chemicals which
cause these similarly charged surface particles are called "surface-
active agents" or "surfactants." Theyare also commonly referred to as
dispersants or sequestering agents.
A well known surfactant, used in laundry detergents, is alkyl
benzene sulfonate (ABS). Even in small quantities, it can create
significant foaming and frothing of water.
The most widely used surfactants are the glassy sodium phos-
phates (polyphosphates) that are effective in the dispersion of clays,
silts, iron and manganese oxides and hydroxides, and most other
fine-grained particulate material than may occur in a well. These
phosphates are usually applied in concentrations of approximately
three percent (25 pounds in 100 gallons of water), in combination
with at least 50 ppm of chlorine (about one-half gallon three percent
household bleach, or Clorox, in 100 gallons of water), and agitated

Well disinfection is a problem
for almost every water well con-
tractor. Many drillers do not fully
understand the way disinfectants
work, how chlorine demand
varies throughout the well and
the difficulties in achieving proper
disinfectant distribution. It is also
rare that drillers understand
exactly how the time that elapses
9tween disinfection and well
..:sting effects the test results.
Some form of chlorine is the
substance most often used in
disinfection, so it is important that
drillers understand how it reacts
in water.
Reaction with reducing ions
such as ferrous, manganous,
nitrite, sulfide and sulfite form the
initial demand (See figure 1). The
chlorine reduced to chlorides in
these reactions has no disinfec-
tion ability. Additional chlorine
will then react with ammonia and
certain organic compounds to
form chloro-organic compounds
and chloramines. Combined
residuals reach a peak (point C),
then decline as more chlorine is
added —offering a limited disin-
fection ability. The point at wich
combined chlorine residuals
reach a minimum and a free
chlorine residual begins to
appear, is known as the break-
aint. Up to this point chlorine
smand (dosage minus residual)
varies with dosage. Beyond the
breakpoint the free chlorine

residual increases directly with
dosage as free chlorine is a rapid
disinfectant.
Much of the available chlorine
lost to long term chlorine demand
is used to oxidize organic matter.
The hydrochloric acid rapidly
reacts with adjacent organic or
mineral matter and normally
increases the possibility of further
chemical reaction.
The major chlorine demand of
concern in well disinfection is not
in the water, but on the surfaces
of the well. Nuisance organisms
(organisms able to reproduce in
the environment of the well) often
produce large quantities of
organic matter. The result is a
high chlorine demand and
sufficient organic energy for the

the well. In wells that have been
inadequately disinfected several
times, over 90% of the demand
may be at the bottom due to
settled slimes loosened in previ-
ous disinfection attempts.
Two chlorine products are
commonly used in well disinfec-
tion, 5.250io sodium hypochlorite
(laundry bleach containing 50,000
ppm available chlorine) and 65 or
70% calcium hypochlorite avail-
2.b!e as a dry granular powder or
tablets containing 650 to 700,000
ppm available chlorine.
Disinfectants are pesticides
regulated by the Environmental
Protection Agency in accordance
with the "Federal Insecticide,
Fungicide and Rodenticide Act"
(FIFRA). Every pesticide container
must bear a Registration and
Establishment Number and be
labeled in accordance with FIFRA
Regulations. Products such as the
hypochlorites have many uses
and may have supplemental use
instructions distributed in bulle-
tins. The user should have the
appropriate instructions present
to be sure of compliance.
Laundry bleach poured into a
well will stratify in the upper well
water. Granular calcium hypo -
chlorite settles too slowly and
dissolves too fast to achieve
uniform distribution. Calcium
hypochlorite tablets have the
opposite problem, initially settling
at about 1.33 fps and dissolving
at about 3% per minute.
Recently the U.S. Department
of Agriculture provided informa-
tion on settling and dissolving
rates. They indicated that about
50% of the granular calcium
hypochlorite dissolves in the
well's upper eight feet.
Other studies indicated that
residuals would be lower at lower
depths for tablets. After the initial
rapid weight loss, the rate of
weight loss was fairly constant-
1% per minute per square .
cm/gm. -
The series of studies also
proved that a properly selected
variety of particle sizes is required
to give uniform dosage through-
out a well bore.
For 150 feet of water with
about 20% of particles reaching
bottom undissolved, the following
size distribution gives fairly
uniform results.
Field use of the prefractured
tablets is extremely fast and easy.
The only other process that can
produce a uniform dosage
throughout the well is the
installation of a tube to the
bottom of the well through which
the chlorine solution is dis-
charged. The tube is gradually
withdrawn as the chlorine
solution is added, exposing all
parts of the well. Use of prefrac-
tured tablets saves over two
hours per well.
There is one serious problem:
Calcium hypochlorite manufac-
turers do not recommend
fracturing tablets under field con-
ditions since there is a danger of
severe chemical burns, fire or
explosion if adequate safety
precautions are not taken. (See
Box) The use of this technique by
drillers will depend upon

portion of the check valve is cut

attached to the reducing
coupling. The cylinder and air
line are pressurized to hold the
check valve closed until the
desired depth is reached. As the
pressure reduces, the cylinder fills
with water and can be withdrawn.
(A safety line may be attached to
the cylinder.) If the cylinder is
lowered to the bottom of the well,
bottom sediments may be
''obtained in addition to a water
sample that may be checked for
chlorine residual.

tions for displacement disinfection
should be reconsidered: A
common recommendation is to
back flush the bore with two bore
volumes of water containing 50
ppm of available chlorine. Water
in the bore is forced back into the
formation and is then followed by
the chlorine solution. If the
chlorine demand is high, slime
sludge and chloro-organic com-
pounds may also enter the
production zone. Depending on
the location and nature of the
production zone, much of the
bore may not receive any
chlorine solution. A good rule to
follow is not to force water from
the bore into the formation until
the bore is fairly clean and the
displaced water contains a
desirable free chlorine residual.
This can only be done after the
installation of a pump.
My recommendations are as
follows: place a strong chlorine
solution in the well before
installing the pump, then the
pump, pipe and wiring will pass
through this chlorine solution on
entering the well water.
Immediately after the pump is
installed, the well should be
pumped to waste over the upper
casing terminal —not into the dis-
tribution system. After the
pumped water clears, it may be
returned to the bore and a
chlorine compound added either
to the return stream or directly to
the bore. The returned water
establishes a recirculating bore
volume from the water level to
the intake up the riser, to the
ar casing terminal to be
..-rned to the bore, or run to
waste. When recirculating 100%
of the pumped water, it is
possible to calculate the chlorine
demand. For accuracy it is
necessary to know the recirculat-
ing bore volume and pumping
rate. A high chlorine residual test
kit is essential. Most are based on
the lodometric Method in
Standard Methods, modified for
easy field use.
Problem wells can have very
high chlorine demands. When 500
ppm goes in and 50 ppm comes
back after one recirculation cycle,
you may wish to increase the
dosage by 200 ppm. When this
happens the pumped water
normally becomes turbid with
released bacterial slimes. The
turbid water should be pumped to
waste rather than returned to the
well. After it begins to clear,
return 30 to 50% of the water to
the bore. Otherwise, clear water
may be obtained quickly from the
production zone but as soon as
circulation is restarted, turbid
water will be pumped from the
upper dead bore volume.
When the pump intake is
located above the production
zone, chlorine can be introduced
into the active pumping bore
volume and lower dead bore
volume in this manner: stop
pumping and add batches of
fractured tablet calcium hypo -
chlorite and give it time to settle
before restarting the pump.
Circulation is not established in
the lower dead bore volume and
the chlorine is rapidly removed
from the active pumping bore
volume.
In some areas of the country,
centering guides are used in most
wells. These have horizontal
surfaces that will retain slimes
and tablet particles and greatly
reduce the chlorine that reaches
the lower dead bore volume.
In areas where nuisance
organisms are common or in
wells where a very low Standard
Plate Count is desired, a means
of establishing circulation from
the bottom of the well to the
58
Water Well Journal. November, 1979

pump intake should be provided.
This can be '/ or 3/4" pipe,
with a hose fitting a few inches
below the upper casing terminal.
The lower two inches should be
perforated to discharge water in
several directions and permit free
discharge of water without pipe
vibration. Calculation of chlorine
demand is simplified if 100%-of
the pumped water is recirculated.
This also reduces chlorine
requirements as none is pumped
to waste except when it is desired
to waste turbid water. If not all
water is recirculated it is neces-
sary to know the ratio of
recirculated water to pumped
water to calculate chlorine
demand.
Without recirculation it is
impossible to be sure that the
chlorine demand of the lower
dead bore volume has been
satisfied. It also is impossible to
remove the residual of bacterial
slimes that have been killed and
loosened by the chlorine.
The importance of under-
standing good well disinfection
processes is illustrated by one
t" conscientious well driller from
whom we learned of this need.
His standard procedure was to
pour two gallons of laundry
bleach into the well. If the health
- department found the well
contaminated he would return,
pour five gallons of bleach into
the well and pump the well to
establish circulation. If the well is
still contaminated, he would use
10 and then 20 gallons of bleach.
Because of the time lag between
disinfection attempts, health
department sampling, return of
bacterial results and notification
and redisinfection, considerable
regrowth of nuisance organisms
.occurred in the recirculating bore
volume between the pump intake
and the static water level in the
well.
Without a tube to establish
recirculation, no amount of
bleach could disinfect the lower
dead bore volume. The exact role
that decomposing organic matter
.__ in the lower dead bore volume
plays in supplying nutrients for

Danger: Corrosive, causes eye damage. May be fatal if
swallowed. Don not get in eyes, on skin, or on clothing. Irritating
to nose and throat. Avoid breathing dust. May cause burns to
broken skin. Wear goggles or face shield and protective clothing
when handling. Wash hands after handling.
Practical treatment (First Aid): If swallowed feed gruel,
cooked cereal, or bread soaked in milk, followed by olive oil or
cooking oil. In case of personal contact, remove excess material
and flush skin or eyes with cold water for at least 15 minutes.
For eyes get medical attention as soon as possible. Remove and
wash contaminated clothing before reuse.
Chemical hazards: Strong oxidizing agent. Do not use moist
or damp utensils. Contamination with moisture, dirt, organic
matter, or other chemicals, or any other foreign matter may start
a chemical reaction with generation of heat, liberation of
hazardous gases and possible generation of fire.
Environmental hazards: This pesticide is toxic to fish. Keep
out of lakes, streams, ponds, or public waters. Permits may be
required for discharges containing this pesticide into public
waters. For guidance contact the regional office of the
Environmental Protection Agency.
Storage and disposal: Keep product dry in tightly closed
container when not in use. Store in a cool, dry, well ventilated
area away from heat or open flame. In case of decomposition
isolate container in open area if possible and flood with large
amount of water. Do not reuse empty container. Rinse empty
container thoroughly with water to dissolve all material before
discarding. Place in trash collection or dispose in approved
landfill area or bury in a safe place.

regrowth of nuisance organisms
is not known. Regrowth in one
well was surprisingly rapid in
about two weeks, regrowth above
the pump intake created a
chlorine demand over 1000 ppm.
To achieve satisfactory disin-
fection, the entire well must be
treated. The highest chlorine
demand should be expected at
the bottom of the well where dirt
and' organic debris settle. Most
wells can be quickly and surely
disinfected by use of proper
techniques. Wells designed or
constructed with dead water
pockets behind the casing may
be impossible to disinfect without
either eliminating the dead water
pockets or making it possible to
establish circulation. In new wells,
fractured tablets can quickly
distribute chlorine in the bore
water. In wells that have nuisance
organism problems much guess
work can be eliminated by
establishing circulation, measur-
ing chlorine residuals and adding
chlorine as needed to satisfy
demand.

Non -Discharge Permit Modification
Permit No. WQ0004936
Ted Industries
New Bern, North Carolina
September 15,1995
1 Introduction
1.1 Background
Teti Industries (Texi'i) previously owned and operated a fiber manufacturing facility
(see Figure 1) located on the northwest side of Stanley Boulevard in New Bern,
North Carolina (site). Amital Spinning Corporation (Amital) began operating the
facility in August 1986 (see property boundaries delineated in Figure 4). Prior to
initiating operations at the facility, Amital contracted Law Engineering to conduct an
environmental audit of the site. A preliminary ground water assessment determined
that the ground water had been impacted by chlorinated compounds.
Chas T. Main (C. T. Main) was subsequently contracted by Teti to address the
impacted ground water. C. T. Main conducted a three phase assessment, designed a
pump and treat ground water remediation system, obtained the initial non -discharge
permit (Permit No. W00004936, issued September 23, 1991), and installed ten
recovery wells.
Four Seasons Environmental, Inc. (Four Seasons Environmental) was contracted to
complete the remaining portion of the ground water remediation system. Only two
of the ten recovery wells (RW-8 and RW-11) installed by C. T. Main produced
sufficient volumes of ground water to allow effective plume control. Four Seasons
Environmental contracted Aquaterra Inc. (Aquaterra) to evaluate and redesign the
system of recovery wells. Modifications to Non -Discharge Permit No. WQ0004936
were approved by the Department of Environment, Health, and Natural Resources,
Department of Environmental Management (DEM) on August 20, 1992, at which
time the remediation system became operational.
1.2 Request for Non -Discharge Permit Modification
The current ground water remediation system is designed to operate at a flow rate of
60 gallons per minute (gpm). However, the ground water disposal system, which
consist of an infiltration gallery, is only capable of handling a discharge rate of 12
gpm. The low infiltration rate in the infiltration gallery is due to the low permeability
of the Post -Miocene sediments that define the soil profile below the gallery. The
most feasible method of increasing the capacity of the ground water disposal system
is to supplement the existing infiltration gallery with an injection well. This injection
well will transfer the treated ground water through the less permeable Post -Miocene
sediments and the Yorktown Formation to the Castle Hayne Formation, which has a
higher permeability. Hydrogeological data for the site has been enclosed in the
Aquaterra, Inc., report entitled Hydrologic Information for the Non -discharge Permit
Modification (Hydrologic Report).

1.3 Existing Recovery, Treatment, and Disposal System
Texfi currently operates a ground water remediation program at the site that began
operation August 20, 1992. The ground water restoration program has been in
operation for approximately 3 years in accordance with Non -Discharge Permit No.
W00004936, which is included in Appendix E of this report. The purpose of the
remediation system is to recover and remove chlorinated compounds from the
ground water and discharge the treated effluent to the subsurface.
The existing ground water recovery system consist of the following extraction wells:
Shallow recovery wells RW-4, RW-7, RW-8, and RW-10
Deep recovery well RW-11
There are two waste streams that make up the ground water treatment system (see
Figure 3):
The primary waste stream consist of the following:
• Influent recovered from extraction wells RW-4, RW-7, RW-10,
and RW-11.
• A holding tank that acts as a combination flow regulator and
settling tank for bacterial and chemical precipitates.
• Air stripper column No. 1
• Air stripper column No. 2
• Compilation of bag filters, pumps, valves, and sampling ports as
shown in Figure 3.
The secondary waste stream consist of the following:
• Influent recovered from extraction well RW-8.
• Carbon Absorption Unit 1
• Carbon Absorption Unit 2
• Compilation of valves and sampling ports as shown in Figure 3.
A total of 12 gpm is currently being gravity discharged from the treatment system to a
400 foot long by 3 foot wide by 8 foot deep infiltration gallery (see Figure 4).
1.4 Concentration of Contaminants in the Castle Hayne Formation
The August 1986 environmental audit of the site, conducted by Law Engineering,
determined that ground water had been impacted by chlorinated compounds
including 1,1,1-trichlorethane and 1,1-dichloroethane.

The July 20, 1995, analysis (SW-846 Method 8240) of the three deep wells (RW-11,
MW-13, MW-14) represents contaminant concentrations in the primary waste
stream prior to remedial treatment (see Appendix A). The analysis detected
chloroethane and 1,1-dichloroethane in RW-11 and MW-13, with the highest
concentrations measured in MW-13 at 4.7 parts per billion (ppb) and 12 ppb,
respectively (see Figure 5 for deep well VOC plume delineation).
Concentrations of treated contaminants in the primary waste stream effluent, that
would be discharged to the injection well, have been below detection limits (BDL)
since August 27, 1992, as shown in Table 1.
1.4 Drinking Water Survey
Aquaterra personnel conducted a door to door drinking water survey of the residents
within a quarter mile of the site property boundaries. Of the residents that could be
contacted, all verified mandatory use of the public water system. Aquaterra
personnel followed this information up by contacting Erik Frank of the New Bern
Water Department, Engineering Division. Mr. Frank confirmed that the
Washington Forks area, including Craven Community College and area residents
were on the city water system.
2 Injection Well Design
2.1 Injection Well Construction
The injection well will be constructed with a 6 inch inside diameter, to a depth of
approximately 90 feet. The expected injection rate is 50 wpm .(72,000 gallons per
day) at an injection pressure of 32.5 pounds per square inch (psi). The well will be
constructed with a galvanized steel casing from ground surface to a depth of
approximately 40 feet and will be screened for the remaining 50 feet. The well will
be grouted from ground surface to a depth of approximately 40 feet. The screen will
be constructed of stainless steel, with an inside diameter of 6 inches and have 0.03
inch slots or an open inlet area of approximately 62 square inches per foot of screen.
An electric conductivity probe will be located in the injection well, at approximately
10 feet below ground surface. This probe will be wired in such a manner as to shut
down the entire treatment system if excessive mounding is detected due to recharge.
2.2 Operating Parameters
The proposed injection well is designed to operate at a flow rate approximately equal
to the rate at which ground water is being pumped from the Castle Hayne
Formation. The deep extraction well (RW-A) located in the Castle Hayne
Formation will be pumped at approximately 50 gpm and the injection well will
discharge ground water to the subsurface at apFRr-
rately 48 to 50 gpm. The 10
gpm recovered from the Yorktown Formation ) will be discharged into the
infiltration gallery, leaving a buffer capacity of 2 gpm.

2.2 Capture Zone Modeling
To determine if a closed loop system exists between the injection well and the deep
extraction well (RW-11), ground water flow lines were mathematically modeled using
the software modeling program RESSQC Module of the Wellhead Protection Area
(WHPA). This program estimated the effective capture zone associated with the
simultaneous pumping and injection of ground water into the Castle Hayne
Formation using aquifer parameters obtained from on -site testing as input data see
Appendix C).
The recovery well was located 212 feet immediately downgradient of the injection
well and full capture of the recharged ground water was demonstrated. Site specific
input parameters for the RESSQC model were obtained from the hydrogeological
data included in the Hydrologic Report. These parameters included a transmissivity
of 10,792 square feet per day, an aquifer thickness of 50 feet, and a hydraulic '6
gradient of 0.016 ft/ft. The results of the modeling program indicate that the capture
zone associated with the operation of RW-11 will be sufficient to recover the ground
water discharged from the injection well provided:
The injection well is positioned directly upgradient from the pumping
well at a distance no greater than 200 feet.
The rate of injection is approximately equal to the rate of recovery
2.3 Conclusions and Recommendations Based on Modeling Results
Analysis of the modeling results generated from the RESSQC, WHPA program
suggest that a conservative spacing between the injection well and the recovery well
would be approximately 100 to 150 feet. The injection well will be located
immediately upgradient of the recovery well as shown in Figure 2, for complete
capture of the discharged ground water to occur. The estimated pumping rate of 50
gallons per minute (gpm) from RW-11 was used as a single variable in the RESSQC
module to determine the sensitivity between the rate of recovery and closed loop
capacity of the system. Complete capture was shown to occur at a recovery rate of 30
gpm (see Appendix C), while the recharge rate remained at 50 gpm. This data shows
that small variations between the pumping rate and injection rate will not
significantly effect the capture zone. However, the system has been designed such
that the rate of injection and the rate of recovery are both approximately 50 gpm.
2.4 Assumptions and Limitations of RESSQC Module
The RESSQC module included in the WHPA program can be used to delineate time
related capture zones for a system of one or more pumping/injection wells that fully
penetrate a isotropic, homogeneous aquifer. Ground water flow must be two
dimensional in the x-y plane, and therefore the aquifer may be confined or
unconfined if the drawdown-to-initial saturated thickness ratio is small. Steady
ground water flow is assumed.

2.5 Surface Area Requirements for the Injection Well Screen
The maximum recommended entrance velocity for an injection well is 0.05 feet per
sec (ft/s) according to Driscoll, 1986. The screened surface area required for safe
discharge of ground water into the surrounding aquifer was evaluated using the
following conditions:
Maximum flow rate of 50 gpm
6 inch inside diameter screen
50 foot length of screen with an intake area of approximately 62 inches
of open inlet area per foot of the screen (0.03 inch slots).
Based on the maximum flow rate and the recommended entrance velocity, the
minimum open surface area of the proposed injection well is approximately 2.2
square feet (see Appendix D). The actual open area available for discharge of
ground water to the surrounding aquifer was calculated using a 50 foot screened
zone, with an intake area of 62 inches of open area per foot of screen (0.03 inch
slots). The resulting available discharge surface area is 21.6 square feet. Since the
anticipated available open area in the injection well is greater than the minimum
required by a factor of 10, the proposed injection well should adequately handle the
estimated entrance velocity.
2.6 Estimated Injection Well Pressure
The pressure used to inject the effluent into the Castle Hayne formation must
overcome the existing hydrostatic forces present below the ground surface. This
hydrostatic force can be determined by multiplying the estimated water column that
would exist between the bottom of the proposed injection well and the mean high
seasonal water table (approximately 60 feet) times the unit weight of water (0.0361
pounds per cubic inch). The resulting hydrostatic force that must be overcome by
the injection pressure is 26 pounds per square inch (psi). As a conservative measure
the injection pressure has been increased by 25 percent to 32.5 psi or 4,680 pounds
per square foot (see Appendix D for calculations).
2.7 Mechanical integrity
The consolidation pressure of the Castle Hayne aquifer was calculated to determine
if the proposed injection well would present a fracture risk to the aquifer (see
Appendix D). The consolidation pressure was calculated using the summation of the
individual stratum unit weights multiplied by the corresponding stratum thicknesses.
The total consolidation pressure for the Castle Hayne aquifer, to a depth of 90 feet,
is 16,328 pounds per square foot (psf).
The injection pressure required to overcome the hydrostatic forces of the ground
water is 4,680 psf (see Section 2.6). Since the consolidation pressure is greater than
the injection pressure by a factor of approximately 3.5, the risk of fracture to the
Castle Hayne aquifer is minimal.

September 15, 1995
Mounding of ground water in the injection well due to recharge is not expected to be
a problem. Pumping test of the deep wells (RW-11, MW-13, MW-14) in the Castle
Hayne formation indicated draw down of less than 1.2 feet in the wells, at a pumping
rate of 51 gpm (see Hydrologic Report). As a safety precaution, an electric
conductivity probe will be located in the injection well, at approximately 10 feet
below ground surface. This probe will be wired in such a manner as to shut down the
entire treatment system if excessive mounding is detected due to recharge.
3 Monitoring and Maintenance
3.1 Monitoring Schedule
The existing monitoring wells will be adequate to assess the impact of the discharge
on the quality of the underlying ground waters. The monitoring wells surrounding
the injection well will be monitored for water level fluctuations on a monthly basis for
the first three months immediately following the activation of the injection well, and
then a semiannual basis. The injection well will be monitored for flow rate and
mounding on a weekly basis for the first month of operation, monthly for the
following 5 months, and then on a semiannual basis. The quarterly sampling
schedule currently in effect at the site will be sufficient to monitor any impact the
injection well may have on plume delineation. However, an additional sampling port
will be added (see Figure 3) on the effluent line designated for injection well
discharge so that the treated effluent can be monitored prior to discharge to the
injection well.
3.2 Maintenance
Bacterial and chemical precipitates have significantly hindered the operation of the
remediation system at the site. A holding tank, currently in place on the system,
receives influent from the recovery wells and acts as a combination flow regulator
and settling tank. However, this has not proven to be an effective deterrent to
deposit buildup within the treatment system and precipitate removal is frequently
required. In addition, reduced recovery rates have been noticed from the pumping
wells due to screen clogging. Therefore the following maintenance program has
been proposed.
The maintenance program for the injection well and existing extraction wells will
consist of periodic treatments with a diluted organic acid wash (hydroxyacetic or
acetic acid). Documentation of this proposed maintenance program has been
included in Appendix B. The use of hydrochloric acid and sodium hypochlorite
solutions to remove bacterial and chemical precipitates has been reviewed, but the
possibility of chloroform generation during maintenance activities makes this an
objectionable alternative.
Page 6 of 7

Texf don -Discharge Permit

September 15, 1995
The suggested maintenance program consist of the addition of 1 gallon of 70 percent
acid per 10 to 15 gallons of standing well water. The mixture would be agitated with
a surge block every 2 hours for a total of 8 hours. The mixture would then be purged
from the well and transferred to the treatment system for neutralization. The
frequency of treatments would be based on observed recovery well draw down rates
and injection well mound measurements.

Aquaterra Job No. 778
Dear Mr. Safrit:
Aquaterra, Inc. (Aquaterra) has been asked by Texfi Industries and their
remediation contractor to assess the ground water conditions at the referenced site.
During this assessment activity, two major characteristics used in developing the
original ground water remediation plan and subsequent Non -Discharge permit
application have changed. Because of these site characteristic changes, Aquaterra
on behalf of Texfi Industries is requesting two permit modifications to the existing
permit.
Modification No.1
The original remediation plan and permit included ground water removal from 00)
one gallon per minute (gpm) shallow recovery wells and (one) 50 gpm intermediate
recovery well. Because of a significant drop in ground water table depth, all but four
of the shallow wells will need to be abandoned. Three of the remaining shallow wells
will require redrilling before they are usable. This redrilling is necessary to provide a
sufficient depth of ground water in these wells for four -inch diameter submersible
., W-4a, RW-7a, and RW-10a. These three wells will
pumps. These three wells are R
be combined with the original 50 gpm recovery well, RW-11, to capture the existing
ground water contaminant plume.
The fourth shallow well, RW-8, will be used to recover ground water impacted by the
past release of Dowtherm heat transfer fluid. The extracted ground water from this
well will be treated by activated carbon adsorption. Two 170-pound carbon canisters
connected in series will be used to treat the round water from ,this W ddl� lusively.
g .. -?
The carbon is required to adsorb the Dowtherm constituents,

Texfi Permit Modification
L2471-92
March 10, 1992
Page 2
las hodification No. 2
The second modification involves the deletion of the proposed metal
treatment/removal system from the permit. Aquaterra has reviewed the data
collected by C.T. Main and concluded that only one round of samples collected and
analyzed were used to determine the need for the metal treatment system. Of these
samples, only three wells, MW-3, MW-4a, and MW-8, had nickel readings above the
state's GA standards for nickel (0.15 parts per million). Only one well, MW-8, was
equal to the same GA standards for zinc (5.0 parts per million). Aquaterra recently
completed a pumping test of the new extraction wells, RW-4a, RW-7a, and RW-10a.
During the pumping test, both discrete and composite samples were collected to
determine the levels of nickel and zinc in the extracted ground water. The samples
were analyzed by EPA Method 200.7 (see Table 1). Based on the results of this
sampling and the low levels of zinc and nickel present in the earlier C. T. Main work,
Aquaterra is requesting the deletion, at least temporarily, of the metal
treatment/removal system.
To monitor the effluent metal levels, Aquaterra is recommending changing Permit
Condition IV.3. to monthly effluent water sampling for metals for the first 12 months
of remediation system operation. If the sample results do not indicate an increase
the levels of nickel and zinc, the sampling would change to quarterly for one year,
and then eventually to semiannual sampling. If the sampling indicates an increase in
the metal levels above the GA standards, Texfi would stop remediation until the high
metal levels could be treated by adding the capability to the overall remediation
system.
To make review of these requests as simple as possible, Aquaterra is including the
original permit and a completed DEM form LLPG 4/91 as attachments. If you have
any questions on the above modification requests, please do not hesitate to contact
us at [phone].

A. Site Geology
B
CEIVFD
APR 11 1991
QERMiTS & ENGINEFF!NC,
Existing geologic cross -sections (drawing R2) ha41e been
modified to reflect hydrogeologic information obtained
during Phase II. Section C (drawing R3) was generated from
existing well 8 boring log data and new information obtained
from wells 10 and 10A. Boring logs for new wells are
located in Appendix C.
The coquina - limestone contact below well 9 has been shown
lower indicating the actual contact position. The apparent
undulating nature of the contact is attributed to a post -
Eocene erosional event where channel scouring was probably
the dominant erosional process.
In the upper unconsolidated post -Miocene sediments, contacts
between sand and clay beds are somewhat variable across the
site. This variability is characteristic of a subaerial
channel dominated depositional environment where meandering
channels (sands) and inter -channel basins (clays) migrate
laterally with time. The contact between these
unconsolidated sediments and the underlying semi -
consolidated sediment of the Yorktown Fm. (coquina bed)
varies about one foot in depth between the deep wells.
Site Groundwater Hydrology
Water level positions for both the upper and lower (Castle
Hayne) aquifers are shown on the potentiometric map (drawing
Rl) and on the accompanying cross -sections (drawings R2.
R3). The water table is super -positioned or the cIa;:
confining beds suggesting that the lower relative hydraulic
conductivity of the clay beds influence the water table
3136-8-1000 6 TEX001WP

position. In the Castle Hayne aquifer the piezometric
(pressure) surface is situated between elevation 10 and 11
feet above mean sea level, from about one to seven feet
below the water table surface. The difference in water
levels is attributed to the semi -confined nature and the
high relative hydraulic conductivity of the lower aquifer.
In hydrogeologic settings such as this w h e r e 1 i th o 1 o g y
changes abruptly between a low hydraulic conductivity unit
and a high conductivity unit, head differences between the
units cause a movement of water from the low hydraulic
conductivity unit to the high. This differential pressure
between the two aquifers is a direct function of contrasting
hydraulic conductivity between the aquifers and indicates
rapid transport of water within the lower aquifer relative
to the unconsolidated sediments above.
Groundwater flow directions in each aquifer may be inferred
from drawing R1. The water table aquifer flows generally
from west to east along flow lines which are perpendicular
to the equipotential lines shown. A groundwater mound is
apparently situated in the vicinity of well 3A creating a
groundwater divide in the northwest corner of the site. A
representative hydraulic gradient for the water table
aquifer is 0.013 ft/ft.
Based on the groundwater measurements taken on 10 July 87,
groundwater flow in the lower aquifer is in the southern
direction under the influence of a 0.0014 ft/ft hydraulic
gradient. Flow in this direction was unexpected taking into
account the nearby Neuse River and the large sink created by
the Martin -Marietta quarry dewatering operation. However,
since the lower pressure surface is defined by three points,
one of which is located in an area where the confining unit
does not exist, it seems likely that the lack of a confining
unit at well 10 would allow a more rapid recharge of water
3136-8-1000 7 TEX001WP

an
into the lower aquifer thus biasing the lower aquifer
pressure surface in the southern direction. It is estimated
that increased elevation control on the lower pressure
surface will support a southeasterly flow direction on a
regional scale.
Groundwater flow velocities in both aquifers may be
estimated from hydraulic conductivity data presented in the
Phase I report and from recently obtained hydraulic gradient
data presented above. Because of the interlayered nature of
the post-miocene sediments, groundwater in the upper aquifer
moves at two different velocities. Using the relationship V
= KHi where V = velocity, KH = horizontal hydraulic
conductivity, and i = horizontal hydraulic gradient, it is
estimated that groundwater transmitted by upper aquifer
clays moves at a velocity of 0.0012 ft/d and through the
sands at 0.11 ft/d. Best available formation indicates that
groundwater flow velocity in the "Castle Hayne" aquifer is
approximately 0.14 ft/d.
Due to the nature of the double aquifer system, vertical
hydraulic gradients are considerably higher than horizontal.
However, this does not necessarily imply that vertical flow
velocities are proportionally as high. The relationship is
possible given the fact horizontal hydraulic conductivities
may be considerably higher than vertical hydraulic
conductivities in sedimentary environments. Clay particles,
which are platy in structure, are deposited in such a manner
that the plates align horizontally with one another thus
allowing groundwater to move with relative ease in the
horizontal direction compared to the vertical direction.
Since the clays control the flux of water in the vertical
direction, it is not likely that the vertical flow velocity
would be equal to the horizontal velocity under conditions
of equal horizontal and vertical hydraulic gradient (KH =
3136-8-1000 8 TEX001WP

KV). In the absence of vertical hydraulic conductivity data
and given the fact that the average vertical hydraulic
gradient is 15 times the horizontal, it is likely that the
vertical flow velocity through the clay is somewhat higher
than the horizontal velocity in the clay.

Aquaterra Job No. 778
Dear Mr. Safrit:
Aquaterra, Inc. (Aquaterra) has been asked by Texfi Industries and their
remediation contractor to assess the ground water conditions at the referenced site.
During this assessment activity, two major characteristics used in developing the
original ground water remediation plan and subsequent Non -Discharge permit
application have changed. Because of these site characteristic changes, Aquaterra
on behalf of Texfi Industries is requesting two permit modifications to the existing
permit.
Modification No. 1
The original remediation plan and permit included ground water removal from (10)
one gallon per minute (gpm) shallow recovery wells and (one) 50 gpm intermediate
recovery well. Because of a significant drop in ground water table depth, all but four
of the shallow wells will need to be abandoned. Three of the remaining shallow wells
will require redrilling before they are usable. This redrilling is necessary to provide a
sufficient depth of ground water in these wells for four -inch diameter submersible
pumps. These three wells are RW-4a, RW-7a, and RW-10a. These three wells will
be combined with the original 50 gpm recovery well, RW-11, to capture the existing
ground water contaminant plume.
The fourth shallow well, RW-8, will be used to recover ground water impacted by the
past release of Dowtherm heat transfer fluid. The extracted ground water from this
well will be treated by activated carbon adsorption. Two 170-pound carbon canisters
connected in series will be used to treat the ground water from this well exclusively.
The carbon is required to adsorb the Dowtherm constituents.

___i Permit Modification
L2471-92
March 10, 1992
Page 2
Modification No. 2
The second modification involves the deletion of the proposed metal
treatment/removal system from the permit. Aquaterra has reviewed the data
collected by C.T. Main and concluded that only one round of samples collected and
analyzed were used to determine the need for the metal treatment system. Of these
samples, only three wells, MW-3, MW-4a, and MW-8, had nickel readings above the
state's GA standards for nickel (0.15 parts per million). Only one well, MW-8, was
equal to the same GA standards for zinc (5.0 parts per million). Aquaterra recently
completed a pumping test of the new extraction wells, RW-4a, RW-7a, and RW-10a.
During the pumping test, both discrete and composite samples were collected to
determine the levels of nickel and zinc in the extracted ground water. The samples
were analyzed by EPA Method 200.7 (see Table 1). Based on the results of this
sampling and the low levels of zinc and nickel present in the earlier C. T. Main work,
Aquaterra is requesting the deletion, at least temporarily, of the metal
treatment/removal system.
To monitor the effluent metal levels, Aquaterra is recommending changing Permit
Condition IV.3. to monthly effluent water sampling for metals for the first 12 months
of remediation system operation. If the sample results do not indicate an increase
the levels of nickel and zinc, the sampling would change to quarterly for one year,
and then eventually to semiannual sampling. If the sampling indicates an increase in
the metal levels above the GA standards, Texfi would stop remediation until the high
metal levels could be treated by adding the capability to the overall remediation
system.
To make review of these requests as simple as possible, Aquaterra is including the
original permit and a completed DEM form LLPG 4/91 as attachments. If you have
any questions on the above modification requests, please do not hesitate to contact
us at [phone].

conditions, the Permittee shall take immediate corrective action, including those as may be
required by this Division, such as the construction of additional or replacement treatment or
disposal facilities.
5. The issuance of this permit shall not relieve the Permittee of the responsibility for damages
to surface or groundwaters resulting from the operation of this facility.
6. Any sludge generated from these treatment facilities must be disposed of in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of

WQ0004936/GW95214
The Groundwater Section has conducted a preliminary review of the subject application, and
cannot recommend issuence of the permit admendment without the following information and/or
clarification:
(1) Cross -sections of the surficial aquifer and Castle Haynes aquifer formations, showing
recovery and monitoring well screens, in addition to the static groundwater levels
in both aquifers and the contaminant contours in both aquifers.
(2) Plan View maps of the contaminant contours in both surficial aquifer and Castle Haynes
aquifer.
(3) A comparison of chemical analyses from (a) the surficial aquifer influent water, (b) the
deeper Castle Haynes aquifer influent water, and (c) the effluent of the treatment system.
This chemical analysis comparison should include all organic/inorganic contaminants, in
addition to what would be considered a normal water quality suite of constituents (TDS,
pH, chloride, manganese, iron, etc.). The purpose of this comparison is to verify that after
the surficial waters and Castle Haynes waters have been treated and mixed, the effluent
water quality injected back into the Castle Haynes aquifer does not degrade the natural
water quality of the Castle Haynes aquifer. This anaysis should consider not only the
organic contaminants, but also the natural water quality difference between the two
aquifers. For example, if the surfical aquifer is high in iron, but the Castle Haynes aquifer
is low in iron, then the injection will degrade the Castle Haynes quality with regards to
iron.

•
(3) From the above chemical analysis, if the Castle Haynes aquifer is determined to be
degraded sufficiently, then it may be necessary to separate the surficial water treatment
system from the Castle Haynes water treatment system.
(4) An analysis of the chemical components/products to be expected in the effluent from the
addition of acetic/hydroxyacetic acid to the wastestream.
If there are any questions please call me at 715-6161.

The Groundwater Section has reviewed the subject permit
application for a 60 gpd discharge into an infiltration gallery.
The remediation plan calls for eleven recovery wells, ten to
withdraw from a shallow Miocene sand formation, and one to
withdraw from the Castle Hayne Formation. Computer modeling of
the remediation site using the analytical models RESSQ and MWCAP
indicates that the recovery well network in combination with the
upgradient infiltration gallery should operate as a closed loop
system. The Groundwater Section recommends approval of the
permit with the following conditions:
1. Any additional groundwater quality monitoring, as
deemed necessary by the Division, shall be provided.
2. All components of the groundwater recovery, treatment
and disposal system shall be properly weather -proofed
to prevent freezing and failure of the system.
3. The influent and effluent from the treatment system
shall be sampled once every two (2) weeks for the first
three (3) months and quarterly_ thereafter for the
parameters specified below:
The results of the sampling and analysis shall be sent
