ATTN: A. Preston Howard, Jr., P.E.
Director, Division of Water Qu~lity
Dear Mr. Howard:
Enclosed please find documentation supporting the establishment oflnterim Maximum
Allowable Concentrations (IMACs) for substances in Class GA and GSA Groundwaters. These
;nfised IMACs have been developed by
·, ) in accordance with the requirements of 15A NCAC 2L.0202(c-e). Throughout the
development of these proposed IMACs, Radian International contacted Dr. Luanne Williams at
the Division of Epidemiology to confirm the toxicological data available for the substances of
interest.
The guidance received by Radian International from the NCDENR Division of Water Quality
instructs that "all supporting documentation" be included in the petition for an IMAC. Since
some of the documents that supported the development of these proposed IMACs are
considerably long, they have just been listed on a·reference page. When deemed appropriate,
excerpts from some of the references were taken and submitted with this package. Two of the
supporting documents are copyrighted articles that were provided by NCDENR. Since we did
not obtain permission to reproduce these copyrighted articles, and since NCDENR, Division of
Epidemiology already possesses copies, we have not included them in this package.
If you have any questions or require additional information regarding these Fiioposed IMA Cs,
please do not hesitate to contact (Jiiiiei!Naa&iiiiS!Oj!Nf-'aiigafUMj) at (9.W:U@Qhf'Q}$:~?'?]).

ACETONITRILE
(CAS No. 75-05-8)
Criteria Specified in 15A NCAC 2L .0202
1. A systemic threshold concentration for acetonitrile can be calculated as shown:
0.006 mg/kg/day * 70 kg * 0.20 (RSC) * (lday I 2L) = 0.042 mg/L
•
Note: The chronic oral RID of 6.0 E-03 mg/kg/day for acetonitrile is
based on a subchronic inhalation study using male and female rats and
mice (USEP A 1997n). The critical effects noted were hepatic lesions and
decreased red blood cell counts and hematocrit. Since this value is based
on a somewhat limited inhalation study, the uncertainty factor (UF)
applied to the oral RID is 3,000. This UF adds a fact9r of 10 for
interspecies extrapolation, a factor of 10 for intraspecies human variation,
and a factor of 10 for the use of a subchronic study. Additionally, a factor
of 3 was applied to account for the lack of teratogenicity studies and that
there is no toxicity data for monkeys, which appear to be more sensitive
than mice and rats acetonitrile exposure. Confidence in the RID and the
database is considered low by the EPA, and confidence in the study is
medium. •
RSC = Relative Source Contribution
2. At this time acetonitrile has not been classified as to human carcinogenicity
(USEP A l 997n).
3. Currently, there is no maximum contaminant level for acetonitrile (USEPA 1996).
4. Currently, there is no secondary maximum contaminant level for acetonitrile
(USEP A 1996).
5. A taste threshold value for acetonitrile was not found in the literature.
6. An odor threshold value for acetonitrile is 300 mg/Lin water (Amoore and

Note: The chronic oral RID Of 1.0 E-01 mg/kg/day for acetophenone is based
on a subchronic study where rats were exposed via dietary intake (USEP A
1997j). The NOAEL was also the highest dose used in the study, hence no
critical effects were noted. An uncertai:qty factor of 3,000 was applied to the
oral RID to account for interspecies variation (factor of 10), intraspecies
variation (factor of 10), extrapolation from subchronic to chronic exposure
(factor of 10), and the lack of reproductive toxicity studies (factor of 3). EPA
has low confidence in the study, database, and RID.

4. Currently, there is no secondary maximum contaminant level for acetophenone
(USEP A 1996).
5. A taste threshold value for acetophenone was not found in the literature.

0.020 mg/kg/day * 70 kg * 0.20 (RSC) * (lday I 2L) * 0.10 (safety factor) = 0.014 mg/L
2.
Note: The chronic oral RID of2.0 E-02 mg/kg/day for acrolein is based
on a subchronic study where rats were exposed via water consumption
(USEPA 1997b). The uncertainty factor applied to the derivation of the
oral RID is 1,000. The HEAS.T table did not specify the critical effect(s)
observed during the study.
RSC = Relative Source Contribution
Safety Factor= 0.10, see explanation at #2, below.
Acrolein is a Class C carcinogen group (a possible human carcinogen). This is
based on the increased incidence of adrenal cortical adenomas to female rats
(USEPA 1997i). Additionally, acrolein is tests positive in several mutagenic
assays, is structurally similar to known or probable human carcinogens, and has a
metabolite that is possibly carcinogenic. There is no data available to assess the
carcinogenicity of acrolein in humans. A quantitative assessment of increased
cancer risk resulting from exposure to acrolein has not been conducted (USEP A
l 997i). If a contaminant is classified in Class C carcinogen group, then a 10-fold
safety factor is applied to the systemic threshold concentration equation to
account for possible carcinogenic effects.
3. Currently, there is no maximum contaminant level for acrolein (USEPA 1996).
4. Currently, there is no secondary maximum contaminant level for acrolein
(USEP A 1996).
5. A taste threshold value for acrolein was not found in the literature.
6. An odor threshold value for acrolein in water is 0.11 mg/L in water (Amoore and

1. A systemic threshold concentration for benzoic acid can be calculated as shown:
2 .
4.0 mg/kg/day * 70 kg * 0.20 (RSC) * (1 day/2L) = 28 mg/L
Note: The oral RID of 4.0 mg/kg/day is based on data regarding the amounts of
benzoic acid and sodium benzoate produced as a food preservative (USEP A
1997d). The FDA estimated a daily per capita intake o.f 0.9-34 mg for benzoic
acid and 34-328 mg for sodium benzoate. At these levels, there are·no reports of
toxic effects in humans. These compounds have "Generally Recognized as Safe"
(GRAS) status by FDA. Therefore, the upper ranges can be considered NOAELs
for benzoic acid and sodium benzoate.
RSC = Relative Source Contribution :
Benzoic acid is a Class D carcinogen group (not classifiable as to human carcinogenicity)
(USEPA 1997d). Benzoic acid received this designation due to the lack of human data
and inadequate data from animal bioassays.
3. Currently, there is no maximum contaminant level for benzoic acid (USEPA 1996).
4. Currently, there is no secondary maximum contaminant level for benzoic acid (USEP A

Note: The chronic oral RID reported in HEAST for benzyl alcohol is 3.0
E-01 mg/kg/da~ (USEPA 1997b). This study was based on a 103 week
study where rat~ were exposed to benzyl alcohol via oral gavage. The

3-CHLOROPROPENE
(CAS No. 107-05-1) .
Criteria Specified in 15A NCAC 2L .0202
1. A -systemic threshold concentration for 3-chloropropene can be calculated as
follows:
0.05 mg/kg/day * 70 kg * 0.20 (RSC) * (1 day/2L) * 0.10 (safety factor) = 0.035 mg/L
2 .
Note: The chronic oral RID of 0.05 mg/kg/day for 3-chloropropene has
been withdrawn from HEAST. It has been used here to determine a
systemic threshold concentration because no replacement value exists in
approved sources. Since the oral RID for 3-chloropropene has been
withdrawn, if it is determined to be a risk driver at a site, the uncertainties
in the withdrawn value should be discussed in the risk assessment.
RSC = Relative Source Contribution
Safety factor= Safety Factor (0.10), see explanation at #2.
3-Chloropropene is classified as a Class C -possible human carcinogen (USEP A
1997a). This designation is based on positive genotoxicity assays and a low, but
biologically important, incidence of forestomach tumors in female mice. 3-
Chloropropene is also structurally similar to other known human carcinogens,
although there is no information regarding its human carcinogenicity. Since there
is limited animal carcinogenicity data, no cancer slope factors have been
calculated for 3-chloropropene. If a contaminant is classified in Class C
carcinogen-group, then a 10-fold safety factor is applied to the systemic threshold
concentration to account for possible carcinogenic effects.
3. Currently, there is no maximum contaminarit level for 3-chloropropene (USEPA
1996).
4. Currently, there is no secondary maximum contaminant level for 3-chloropropene
(USEPA 1996).
5. A taste threshold value for 3-chloropropene was not found in the literature.
6. ·An odor threshold value for 3-chloropropene was not found in the literature.
THE RECOMMENDED GROUNDWATER QUALITY STANDARD FOR 3-
CHLOROPROPENE IS 0.035 MG/L.

2.
calculated as shown:
0.080 mg/kg/day * 70 kg * 0.20 (RSC) * (lday I 2L) = 0.56 mg/L
Note: The oral RID Of0.08 mg/kg/day for MIBK is from the HEAST
database (USEPA 1997b). This value was based on a 13 week study
where rats were exposed via oral gavage. The critical effects noted were
overall lethargy and increased liver and kidney weights in females. The
females also demonstrated increased urine protein conceµtrations. This
chronic oral RID was withdrawn from IRIS in 1991 and is still under
review.
RSC = Relative Source Contribution
At this time MIBK has not been classified as to human carcinogenicity (USEP A
1997g).
3. Currently, there is no maximum contaminant level for MIBK (USEPA 1996).
4. Currently, there is no secondary maximum contaminant level for MIBK (USEPA

3.
4.
5.
6.
0.05 mg/kg/day * 70 kg * 0.20 (RSC) * (1 day/2L) = 0.35 mg/L
Note: The oral RID of 0.05 mg/kg/day is based on a subchronic (90) day study
where rats were exposed to 2-methylphenol via oral gavage (USEPA 1997e). The
critical effect observed was decreased body weight and neurotoxicity. The
NOAEL was set at 50 mg/kg/day. An uncertainly factor of 1000 was applied to
the RID to account for both intraspecies and interspecies variability and for
extrapolation of a subchronic effect level to its chronic equivalent. No modifying
factors were used. Confidence is the study is high because the critical studies
provided adequate toxicological endpoints that included both general toxicity and
neurotoxicity. The con~dence in the RID is medium until additional chroi:iic
toxicity studies and reproductive studies are available.
RSC = Relative Source Contribution
2-Methylphenol is a Class D carcinogen group (not classifiable as to human
carcinogeni~ity) since there is no information available on the carcinogenic effects of 2-
methylphenol in humans (USEPA 1997e).
Currently, there is no maximum contaminant level for 2-methylphenol (USEPA 1996).
Currently, there is no secondary maximum contaminant level for 2-methylphenol
(USEP A 1996).
A taste threshold value for 2-methylphenol was not found in the literature.
An odor threshold value for 2-methylphenol was not found in the literature.
THE RECOMMENDED GROUNDWATER QUALITY STANDARD FOR 2-
METHYLPHENOL IS 0.35 MG/L .
1. 1. 1.2-TETRACHLOROETHANE
(CAS No. 630-20-6) .
Criteria Specified in 15A NCAC 2L .0202
1. A systemic threshold concentration for 1, 1, 1,2-tetrachloroethane can be calculated
as shown:
0.030 mg/kg/day * 70 kg * 0.20 (RSC)* (1 day/2L) * 0.10 (safety factor) = 0.021 mg/L
Note: The chronic oral RID of 3.00 E-02 mg/kg/day is based on a chronic
study that exposed rats to 1, 1, 1,2-tetrachloroethane via oral gavage (USEP A
1997k). The critical effects observed were mineralization of the kidneys in
males and hepatic clear cell change in females. The uncertainty factor applied
to the derivation of this RID was 3000. This was to account for extrapolation
from a LOEL (factor of 10), interspecies variability (factor of 10), intra human
variability (factor of 10), and lack of reproductive and supporting chronic
toxicity studies (factor of 3). No modifying factors were used. The overall
confidence in the RID, study, and the database is low.
RSC= Relative Source Contribution
Safety Factor= 0.10, see explanation at #2, below.
2. 1,1,1,2-Tetrachloroethane is a Class C carcinogen group (a possible human
carcinogen). This is based on the incidence of combined hepatocellular adenomas
and carcinomas in female mice (USEPA 1997k). There is no data available to
assess the carcinogenicity of 1, 1, 1,2-tetrachloroethane in humans. The drinking
water concentration that corresponds to an incremental lifetime cancer risk of
1 *10-6 is 0.001 mg/L (USEPA 1997k). If a contaminant is classified in Class C
carcinogen group, then a 10-fold safety factor is applied to the systemic threshold
concentration equation to account for possible carcinogenic effects.
3. Currently, there is no maximum contaminant level for 1,1,1,2-tetrachloroethane
although it has been listed for regulation (USEP A 1996).
4. Currently, there is no secondary maximum contaminant lev~l for 1,1,1,2-
tetrachloroethane (USEP A 1996). ·
5. A taste threshold value for 1, 1, 1,2-tetrachloroethane was not found.
6. An odor threshold value for 1, l, 1,2-tetrachloroethane was not found.

TETRAHYDROFURAN
(CAS No. 109-99-9) .
Criteria Specified in l 5A NCAC 2L .0202
1. A systemic threshold concentration for tetrahydrofuran can be calculated as
shown: ·
0.086 mg/kg-day * 70 kg * 0.20 (RSC) * (lday I 2L) = 6.602 mg/L
Note: The oral RID Of 0.086 mg/kg-day for tetrahydrofuran is a derived
value. This oral RID is a route extrapolation based on the inhalation RID
of 0.086 mg/kg/day, which is a provisional value (USEPA 1993). The
inhalation RID is based on a subchronic study in which mice were
exposed to tetrahydrofuran vapor for 6 hr/day, 7 day/week, for 13 weeks.
The NOAEL was set at 600 ppm (1,770 mg/m3) and the LOAEL at 1800
ppm (5,310 mg/m3). An uncertainty factor of 1,000 was applied to
account for the use of a subchronic study (factor of 10), intrahuman
variability (factor of 10), extrapolation from mice to humans using
dosimetric adjustment (factor of 3), and ~atabase limitations (factor of 3).
The critical effect observed was liver cytomegaly and liver weight
increases at 1800 ppm. Other effects noted were decreased absolute
weight in the spleen (at 5000 ppm) and thymus (at 1800 ppm and 5000
ppm). The NCEA workgroup suggested that these endpoints may be the
critical effect, but since no corresponding histopathology was observed
these were not considered unequivocal adverse effects (NCEA 1995). The
EPA Region IX office has considered the oral RID of 0.086 mg/kg-day
based on the NCEA risk assessment oftetrahydrofuran as an acceptable
value in the absence of other data (USEP A 1998). NCEA ascribes
medium confidence to the provisioµal inhalation RID. No human toxicity
data was available.
RSC = Relative Source Contribution
2. Tetrahydrofuran has not been classified as to its potential to cau~e cancer in
humans.
3. Currently, there is no maximum contaminant level for tetrahydrofuran (USEP A
1996).
4. Currently, there is no secondary maximum contaminant level for tetrahydrofuran
(USEPA 1996).
5. A taste threshold value for tetrahydrofuran was not found in the literature.

2.
0.004 mg/kg/day ~ 70 kg * 0.20 (RSC)* (1 day/2L) * 0.10 (saf~ty factor)= 0.0028 mg/L
Note: The oral RID of 0.004 mg/kg/day is based upon two subchronic studies in
which mice of both sexes were exposed to 1,1,2-trichloroethane in drinking water
(USEPA 1997c). The critical effect observed in this study was clinical serum
chemistry, such as erythrocyte effects in females. The uncertainty factor applied
to the derivation of this RID was 1000 to account for interspecies and intra human
variability, and extrapolation to lifetime exposure from the subchronic dosing.
No modifying factors were used .. The overall confidence in the RID, study, and
the database is medium.
RSC =Relative Source Contribution
Safety Factor= 0.10, see explanation at #2, below.
1,1,2-Trichloroethane is a Class C carcinogen group (a possible human carcinogen). This
is based on the development ofhepatocellular carcinomas in one strain of mice exposed
via oral gavage (USEPA 1997c). There is no data available to assess the carcinogenicity
of 1,1,2-trichloroethane in humans. The drinking water concentration that corresponds to
an incremental lifetime cancer.risk of 1 *10-6 is 0.0006 mg/L (USEPA 1997c). Ifa

FIELD PROCEDURES
This appendix briefly describes the field procedures used in conducting the CSA.
The procedures pertain to cone penetrometer and direct-push probing, well installation, sample
collection and handling, field measurements, equipment decontamination, and waste
~anagement.
D.1 Surface Water Sampling
Water samples were collected fr<?m selected points in the drainage ditch to assess
the surface water quality. At each location, sampling team members wore new, disposable
nitrile gloves. Grab samples were collected at each of five sampling locations beginning with
the downstream location and proceeding upstream. Samples were collected from the middle part
of the channel by partially dipping the mouth of the sampling bottle or vial below the water
surface with the container pointed upstream .
The sample for purgeable aromatic (VOC) analysis was collected first in each
case. Three clean, labeled, 40-mL glass VOA vials were completely filled and sealed without
headspace using Teflon-lined septum caps. Each vial contained sufficient hydrochloric acid to
lower the sample pH to less than 2. Immediately upon sample ~ollection, the vials were placed
into an insulated cooler containing wet ice for storage.
The sample for SVOC analysis was collected next. One clean, labeled, 1-L amber
glass bottle was filled and sealed with a Teflon-lined cap. Immediately upon sample collection,
the bottle was placed into an insulated cooler containing wet ice for storage.
The sample for metals analysis was collected last. One clean, labeled, 500-mL
plastic bottle was filled and sealed with a plastic cap. The bottle contained nitric acid to l<?wer
the sample pH. Immediately upon sample collection, th~ bottle was placed into an insulated
cooler containing wet ice for storage .
la c:\hamilton\washington\csa-rpt (12/15/98) D-1
Procedures used to manage samples after collection are described in
Section D.11.
D.2 Soil Boring and Sampling
Soil borings were advanced to collect samples for laboratory analysis and to
characterize the subsurface geology. Borings were advanced using cone penetrometer
techniques (CPT) and direct push technology (DPT). Several shallow borings were advanced
using a hand auger. Each method is described below. Following completion of probing and
sampling, each boring was abandoned by grouting as described in Section D.13. Management of
investigation-derived waste (IDW) is discussed in Section D.14.
D.2.1 Cone Penetrometer Techniques
Soil and geologic conditions were assessed using a cone pen~trometer equipped
•
with a fuel fluorescence detector to profile the soil stratigraphy and to screen for TPH •
distribution in the soil. The cone penetrometer was used to develop detailed geologic logs for
interpreting the stratigraphy of the underlying deposits and for identifying the occurrence of
potential confining beds, in particular. The cone penetrometer is a combination of geotechnical
and environmental sensors that was hydraulically pushed into the ground. Data were collected
in-situ and transmitted electronically to an on-board computer for analysis and display. The
cone penetrometer probe measured point resistance, sleeve friction, and pore water pressure.
From this data, the computer determined a range of soil parameters based on established
correlations. Soil type was identified from the ratio of sleeve friction to point resistance, and soil
strength is related to point resistance. Similarly, water table depth was estimated by correlating
the instrument depth with the measured hydraulic head, and measurement of excess pore
pressure generated by the penetration process identified low permeability layers. Use of a cone
penetrometer equipped with a fuel fluorescence detector simultaneously measured TPH
concentrations in the soil as the tool was advanced into the ground. Although not intended for
production soil sampling, the cone penetrometer tools were used in conjunction with a discrete
interval soil sampler to collect a limited m~mber of depth-specific soil samples. The addendum •
to this appendix describes these cone penetrometer techniques in greater detail.
la c:\hamilton\washington\csa-rpt (12/15/98) D-2
• D.2.2 Direct Push Technology
A truck-or "mule" -mounted Geoprobe was used to collect soil samples for
laboratory analysis from various locations on the site. The Geoprobe was positioned over the
selected sampling point and a decontaminated closed piston sampler was advanced to the
prescribed depth using hydraulically-applied static force and a percussion hammer. A new,
clear, polymer liner was sealed within the sampler by the closed piston tip which locks into the
cutting shoe. At the desired depth, the piston was unlocked allowing it to retract into the sample
tube and the sampler was driven through the prescribed sampling interval. The sampling tools
were then retrieved and the soil sample was handled as described in Section D.2.4.
D.2.3 Hand Auger
A clean, steel hand auger assembly consisting of a detachable handle, extension
rod, and auger bucket was used to collect soil samples for faboratory analysis at several sampling
• locations. At each sampling location, the hand auger was advanced to the top of the desired
sampling interval and then retrieved. The auger bucket was then replaced with a clean bucket
and reinserted into the open auger hole. The hand auger was advanced farther until the auger
buc_ket was full, and then retrieved. Soil from the top and bottom of the sample was removed
from the bucket using a clean spoon and discarded. The remaining soil was then collected and
handled as described in Section D.2.4.
•
D.2.4 Soil Sample Collection
Upon retrieval at the surface, the soil sampler was opened, exposing the soil in the
split spoon and allowing the polymer liner to be removed from the closed piston sampler. The
sample was then prepared immediately by an engineer or scientist wearing new, disposable
nitrile gloves. Soil in the polymer liner was then exposed by splitting the liner with a clean,
knife blade and a lithologic description of the soil sample was noted and recorded. The soil
sample was then prepared for laboratory analysis as follows. The sample for purgeable TPH and
voe analyses w~s transferred directly from the bottom of the sampler into a clean, labeled 4-
oz. sample jar that was filled completely an4 sealed with a Teflon-1.ined cap .. The sample for the
la c:\hamilton\washington\csa-rpt ( 12/ 15/98) D-3
remaining analytes was then placed in a clean, disposable pan where it was thoroughly mixed
before being transferred into a clean, labeled 9-oz. jar and sealed with a Teflon-lined cap. Upon
sealing, each sample was immediately placed into an insulated cooler containing wet ice for
storage. Procedures used to manage samples after collection are described in Sec~ion D.11.
D.3 Groundwater Screening
Initial groundwater screening was performed using direct push technology to
collect discrete water samples for immediate analysis of voes by field gas chromatograph/mass
spectrometer (GC/MS). Selected VOCs, typical of the petroleum and solvent constituents that
were previously detected in the groundwater, were used as indicators of chemical distribution.
Screening samples were collected from cone penetrometer stratigraphy profiling locations and
from several other locations indicated by the screening results. Two to three vertically separated
samples were collected at each location. Replicate samples to confirm the screening results were
collected at three locations and submitted for laboratory analysis. Groundwater screening
•
samples collected during the later phase of the CSA were submitted for laboratory analysis by •
Method 8260B.
A truck-or "mule" -mounted Geoprobe was used to collect groundwater samples
for analysis. The Geoprobe was positioned over the selected sampling point and a
decontaminated screen point sampler was advanced to the prescribed depth using hydraulically-
applied static force and a percussion hammer. When the sampler reached the desired depth, the
wire-wound screen was exposed to permit formation water to enter the sampling assembly. A
clean Tubing Check-Valve System was fully inserted into the assembly by the sampling team
and quickly oscillated up and down to remove groundwater from the sampler. The water sample
was transferred directly from the tubing into three 40-mL VOA vials. The vials were completely
filled and sealed without headspace using Teflon-lined septum caps. The vials were submitted
immediately to the field laboratory for on-site analysis. Replicate samples collected for
laboratory analysis were also transferred into three 40-mL VOA vials, preserved with
hydrochloric acid, and placed into an insulated cooler containing wet ice for storage. Samples
collected during the later phase of the assessment were handled in the same manner as the
la c:\harnilton\washington\csa-rpt ( 12/21/98) D-4
•
•
•
replicate samples. Procedures used to manage the samples after collection are described in
Section D.11.
When sample collection was completed at a particular depth interval, the sampler
•'
assembly was removed from the probe hole. Another decontaminated screen point sampler
assembly was then inserted into the probe hole and advanced to the next desired depth interval.
Sampling proceeded at progress'ively lower depth intervals as described previously until all
samples at a particular location had been collected. Following the completion of sampling, the
probe hole was immediately abandoned by grouting as described in Section D.13.
D.4 Well Installation
Wells were installed using DPT, hollow-stem auger (HSA), or mud-rotary
methods. The general procedures of each method are discussed below .
D.4.1 Direct Push Technology
Initially, four well pairs, each consisting of a shallow well and a deeper well,
were installed at locations selected based on the results of the groundwater screening.
Subsequently, two observation wells and three shallow monitoring wells were installed east of
the employee parking lot, and a fifth well pair was installed off-site. Each well was installed by a
truck-or "mule" -mounted DPT rig. The DPT rig was positioned over the selected well site and
decontaminated probe rods were advanced to the prescribed depth using hydraulically-applied
static force and a percussion hammer. When the rods reached the desired depth, an assembly of
half-inch I.D., flush-threaded, Schedule 80, PVC casing and .010-inch factory-slotted, prepacked
screen was inserted. The screens are prepacked with 20/40 grade silica sand and the outer
component of the screen is stainless steel wire mesh. All casing and screen was new and
received from the manufacturer sealed in protective plastic packaging. Twelve feet of screen
were installed in the observation wells, nine feet of well screen were installed in each of the
deeper monitoring wells, and six feet of well screen were used in each of the shallow monitoring
• wells. A filter pack consisting of clean, filter sand was emplaced into the annulus above each
prepacked well screen. The filter pack extended from the top of the prepacked screen to at least
la c:\hamilton\washington\csa-rpt ( 12/15/98) D-5
one foot above the top of the sereen. A seal of bentonite pellets at least one foot thick was
emplaced above the filter pack and, for the shallow wells, hydrated with potable water. The
remaining annulus in all wells was then filled with neat cement. Each well was completed above
grade within a lockable steel casing surrounded by a cement apron. Well heads were fitted with
slip caps and the outer casings were secured with keyed-ali~e locks to preclude unauthorized
access. Following installation, all wells were developed as described in Section D.5.
D.4.2 Hollow-Stem Auger
A HSA was used to install pumping well PW-1 and monitoring well MW-228. A
4.25-inch I.D. HSA was used to advance the borehole to the proposed depth at each well
location. Following the completion of drilling, an assembly of two-inch I.D., flush-threaded,
Schedule 40, PVC casing and .010-inch factory-slotted screen was inserted into the auger. All
PVC casing and screen was new and received from the manufacturer sealed in protective· plastic
packaging. A filter pack consisting of clean, Grade 1 silica sand was emplaced into the annulus
around each well screen. The filter pack was added by gravity filling in both wells. The filter
pack extended from the bottom of each boring to at least one foot above the top of the screen. A
seal ofbentonite pellets at least one foot thick was emplaced above the filter pack in MW-228
and hydrated. A bentonite slurry was tremied in place to seal PW-1. Placement of the filter pack
and bentonite seal were monitored using a clean, weighted fiberglass tape. The remaining
annulus in the wells was then filled with neat cement using the tremie method for
PW-1 and the gravity filling method for MW-228. Well MW-228.was fitted with a locking
expansion cap and was completed at-grade within a water-tight vault surrounded by a cement
apron. Well PW-1 was finished above-grade within a locking, protective casing surrounded by a
cement apron.
The HSA auger was also used to set 10-inch diameter outer casings for wells
MW-226 and MW-227 before mud-rotary drilling commenced.
la c:\hamilton\washington\csa-rpt (12/15/98) D-6
•
•
•
•
•
D.4.3 Mud Rotary
Mud rotary drilling was utilized during the installation of monitoring wells
MW-226 and MW-227. "Flowing" sands encountered in the deeper boring associated with these
wells render the HSA method ineffective for well installation. Consequently, the mud rotary
method was used as an alternative drilling technique after 10-inch diameter, outer surface casing
had been installed using a HSA, grouted in place, and allowed to set.
Mud rotary drilling utilized a 5.875-inch diameter auger-head bit and bentonite-
based drilling fluid. The drilling fluid was prepared by mixing pure sodium bentonite with
potable water obtained from the facility. Upon reaching the prescribed borehole depth at
location MW-227, drilling was terminated and a 2-inch I..D. well was installed at-grade as
described in Section D.4.2. At location MW-226, drilling terminated at the top of the Yorktown
confining layer and a 6-inch l.D. steel casing was installed, grouted· in place, and allowed to set.
Subsequently, mud rotary drilling continued through the casing into the Castle Hayne formation
where drilling was terminated and a 2-inch l.D. well was installed at-grade as described in
Section D.4.2.
D.5 Well Development
All wells were developed by overpumping. Development was continued until the
water was free of sediment or until no additional improvement in quality was apparent.
Development of the wells installed by the mud-rotary method was assisted by "thinning the
drilling fluid in the boreholes as much as possible during well installation. Development water
was contained and managed as discussed in Section D.14.
D.6 Surveying
All probing locations, surface water sampling points, and wells were surveyed
using a Total Station Surveying Instrument to establish horizontal and vertical control. Positions
• of the probing locations and the wells were established relative to permanent site features. All
locations were surveyed to the nearest 0.1 foot. At each monitoring well, the vertical elevation,
la c:\hamilton\washington\csa-rpt (12/15/98) D-7
referenced to mean sea level, was surveyed to the nearest 0.01 foot. The elevation was
established at the measuring p0int marked on the edge of each uncapped PVC well casing.
D.7 Water-level Measurement
The water-level in a well was measured before collecting a groundwater sample
to determine the volume of water to be purged. A round of synoptic water-level measurements
' .
was also performed in selected wells to interpret groundwater flow directions and to estimate
hydraulic gradients at the site. Water levels were measured according to the following
procedure.
The depth to water in each monitoring well was measured with a clean electric
water-level indicator. The measuring point marked on the top of each PVC well casing served as .
the reference point. To minimize errors, the measurement was repeated until two consecutive
readings agreed within 0.01 foot. Results were recorded in the field notebook. For consistency
•
between the wells, one observer using a single water-level indicator measured the depth to water •
during the synoptic water-level measurements. The water-level indicator was then
decontaminated as described in Section D.12 prior to moving to another well.
D.8 Well Purging
Prior to groundwater sampling, each well was purged to ensure that water
representative of the aquifer was collected. Each monitoring well was purged prior to sample
collection by removing three well volumes of water. Purging was performed using either a new
disposable, closed-top bailer and nylon line; a clean inertial foot-valve pump and tubing, or a
peristaltic pump equipped with new tubing at each well. The following general procedures were
followed in each case.
First, the length of the water column in each well was calculated based on the
well depth and the depth to water measured in the well prior to beginning purging. The length of
the water column was then converted to a volume measurement by considering the well
la c:\hamilton\washington\csa-rpt (12/1 S/98) D-8
•
• diameter. Multiplying the resulting value by three established the amount of water to be purged
from the well.
Next, purging was initiated and water from the bailer or pump discharge tubing
was collected in a graduated bucket to measure the amount.ofwater removed. Purging
continued until the required three well volumes of water had been removed. The time, the
method of purging, and the volume of water removed were recorded in the field notebook.
Immediately upon the completion of purging, samples were collected as described
in Section D.9. All purge water was managed as described in Section D.14.
D.9 Groundwater Sampling
This section describes the procedures used in sampling groundwater from selected
monitoring wells. At each well, sampling team members wore new, disposable nitrile gloves.
• With the following exception, the equipment used to purge a particular monitoring well was also
used to collect the water sample from the well. In cases where a well was purged with a
peristaltic pump, the VOC sample was collected using a new, Tubing Check-Valve system. The
use of small diameter sampling tube ensured a slow stream of w.ater that minimized the potential
for volatilization. The remaining samples· at the well were collected using the peristaltic pump.
At monitoring wells purged using a bailer, all samples were collected also using the bailer. The
bailer was slowly lowered and retrieved to minimize aerating the sample. The sample was
gently transferred from the bailer directly to the VOA vials. The SVOC and metal samples were
then collected directly into their respective containers through the peristaltic pump tubing.
The sample for voe analysis was collected first in three clean, labeled, 40-mL
glass VOA vials that were completely filled and sealed without headspace using Teflon-lined
septum caps. Ea~h vial contained hydrochloric acid to lower the sample pH, unless the acid
produced a gaseous reaction with the natural water chemistry. In those cases, the samples were
not acidified and noted as requiring analysis within 7 days. Immediately upon sample collection,
• the vials were placed into an insulated cooler containing wet ice for storage.
la c:\hamilton\washington\csa-rpt (12/15/98) D-9
The sample for SVOC analysis was collected in one clean, labeled, 1-L amber
glass bottle that was filled and sealed with a Teflon-lined cap. Immediately upon sample
collection, the bottle was placed into an insulated cooler containing wet ice for storage.
The sample for metals analysis was collected in one clean, labeled, 500-mL
plastic bottle that was completely filled and sealed using a plastic cap. The bottle contained
ni~c acid to lower the sample pH. Immediately upon sample collection, the bottle was placed
into an insulated cooler containing wet ice for storage.
After the last laboratory sample was collected at a well, a sample aliquot was
collected and measured for pH, temperature, and specific conductance. Selected samples were
also measured for dissolved oxygen, oxidation-reduction potential, and ferrous iron. All
instruments were calibrated prior to each day's use according to the manufacturer's instructions.
The sample was located in a protected area during measurement and the results were recorded ·as
soon as the readings had stabilized to ensure accurate and representative values.
Sampling activities conducted at all wells were documented in the field notebook.
Data recorded included the sampling team, sample identification information, purging and
collection methods, and the results of field measurements.
D.10 Field Quality Control (QC) Samples
Three types of Quality Control (QC) samples were prepared and submitted to the
analytical laboratory with the field samples. The QC samples, which were used to verify that all
sampling and analytical techniques were performed properly, included trip blanks (TB),
equipment blanks (EB), and matrix spikes/matrix spike duplicates (MS/MSD).
D.10.1 Trip Blank
A trip blank is a VOC sample vial filled in the laboratory with organic free water,
transported to the site, handled like a sample, and returned to the laboratory for analysis. Trip
la c:\hamilton\washington\csa-rpt (12/15/98) D-10
•

•
•
•
•
blanks were not opened in the field. The trip blank for soil samples is the same as for water
samples.
Orie trip blank accompanied every cooler of soil and water samples sent to the
laboratory for the analysis ofVOCs. This blank was analyzed for VOCs only.
D.10.2 Equipment Blank
An equipment blank is organic free water that is poured into or pumped through a
sampling device, transferred to a sample bottle, and transported to a laboratory for analysis.
Equipment blanks were prepared for the closed piston sampler used to collect soil
samples and for the bailer, tubing, and foot-valve pump used to collect the groundwater samples . .
The blanks were analyzed for all laboratory analyses requested for the field samples. Equipment
blanks were collected at a rate of 5% of all field samples .
D.10.3 Matrix Spike/Matrix Spike Duplicates
Matrix spike/matrix spike duplicates (MS/MSD) samples were used to evaluate
the effects of the c~emical matrix of water and soil samples on the analytical process. MS/MSD
samples were collected in the same way as field samples. In the laboratory, known amounts of
select target analytes were added. Measurements frem these spiked samples were compared to
data from the unspiked samples to evaluate the precision and accuracy of the analytical process.
MS/MSD samples will be collected at a rate of 5% of all field samples.
D.11 Sample Documentation, Packaging, and Shipping
.
The following procedures were used to manage the field samples and QC samples
following collection. All samples were classified as environmental samples for shipping
purposes .
la c:\hamilton\washington\csa-rpt (12/15/98) D-11
D.11.1 Sample Custody and Documentation
Once collected, all samples remained in the possession of the sampling team or
were locked in a vehicle at all times prior to transfer of custody for shipment to the laboratory.
Prior to packaging, each s~mple's unique identification number was entered on the chain of
custody record along with the names of the samplers, type of sample, time of collection, number
of containers, requested analyses, and any sample preservation used. A separate chain of
custody accompanied each sample shipping container.
D.11.2 Sample Packaging
The following procedure was followed in preparing each ·sample shipping
container. A medium-sized, insulated cooler was selected and its drain plug was sealed with
duct tape on both the interior and exterior sides of the cooler. The cooler was lined with a large
plastic bag and a layer ofvermiculate was added to the bottom of the cooler. Each sample
•
container was placed in an appropriately sized polyethylene freezer bag and sealed. Several •
layers of sample bottles were then placed in the cooler with fresh ice, double bagged in gallon-
size polyethylene freezer bags, added on top of and below each layer. The plastic bag lining the
cooler was then secured with duct tape and the signed chain of _custody was inserted into a
plastic freezer bag and affixed to the interior side of the cooler lid. The cooler lid was taped shut
and secured with two signed custody tapes. Appropriate shipping labels were then affixed to the
top and sides of the cooler.
D.11.3 Sample Shipment
The packaged samples were delivered to a commercial overnight carrier for
shipment to the laboratory on a priority basis. A copy of each air bill was retained to document
the shipment.
la c:\hamilton\washington\csa-rpt (12/15/98) D-12
•
• D.12 Equipment Decontamination
All non-dedicated, non-disposable sampling equipment was decontaminated
between each use: A plastic-lined decontamination pad was constructed in the rear of the facility
and served as a central decontamination area. All large equipment was decontaminated in this
area. Most small equipment (i.e., instrument probes, ~ampling spoons, etc.) was decontaminated
at each work site; however, all wash and rinse water were containerized and transported to the
central decontamination area for temporary storage pending proper disposal.
D.12.1 Large Equipment
Large equipment included all downhole probing tools that came into contact with
soil during test probing, soil sampling, and well installation. After each use, the equipment was
transported to the central decontamination area for further cleaning using a high-pressure steam
wash from the site's potable water supply. Soil samplers were also scrubbed in a phosphate-free
• soap and water solution followed by rinsing liberally in potable water. Finally, the
decontaminated equipment was allowed to air dry.
•
D.12.2 Small Equipment
Small equipment was decontaminated by washing in a phosphate-free soap and
water solution. The equipment was then rinsed in deionized water and allowed to air dry.
D.13 Borehole Abandonment
All test borings not completed as monitoring wells were immediately abandoned
by grouting using neat cement. The prepared grout mix was added to the borehole using the
gravity fill without tremie method until undiluted grout flowed to the surface. A small amount
of additional grout was placed at the land surface to offset potential shrinkage or settlement.

D.14 Management of Investigation-Derived Waste
Investigation-derived waste (IDW) was primarily water generated from well
development, well purging, and equipment decontamination. This IDW was con~ained in 55-
gallon, DOT-approved, steel drums. Upon filling, each drum was sealed and labeled as to point
of origination, date of accumulation, and contents. The drums were staged on-site within the
fenced portion of the facility pending proper disposal.
