1.0 Introduction
The BASF Former Operations and Technical Marketing Building 660 facility (the Site) is located west of the
intersection of United States (U.S.) Highway 19/23.and Sandhill Road in Enka, Buncombe County, North
Carolina (Groundwater Incident #85380), approximately five miles west of the Asheville city limits. The Site
location, is illustrated on Figure 1. The Site is part of a larger area of property that continues across Hominy
Creek, formerly owned by BASF, which abuts Highway 19/23 to the north and Sandhill Road to the south. A
portion of the Site property and the facility buildings are now owned by Asheville Buncombe Technical College
(AB -Tech). BASF has retained ownership of Building 660 and leases this structure to AB -Tech. The Site and
property boundary information are shown on Figure 2. Contamination exists in two separate groundwater
plumes, designated as the North Plume and the South Plume.
The purpose of this report is to summarize the results of the August 2008 annual sampling event and provide .
an evaluation of the EHCTM injection effectiveness, performed in accordance with the Corrective Action Plan
(CAP) prepared in January 2007 (ENSR, 2007).
1.1 . Background
Volatile organic. compounds (VOCs) and metals were detected in groundwater during a due diligence
assessment of the BASF property in March 2000 initiated by AB -Tech. Subsequently, ENSR, acting on behalf
of BASF, conducted multiple site assessment activities (Phases 1 to 5) that are reported in the Limited Site
Assessment (ENSR, 2000), Comprehensive Site Assessment (ENSR, 2001) and Comprehensive Site
Assessment Addendum (ENSR, 2002).
Four probable source areas for the contaminants were identified:
• Soil area at Building 660;
• A former chemical pit area north of the parking lot;
• The dumpster pad area east of Building 660; and
• A former dry well area east of Building 660.
Assessment activities targeted soil, groundwater, and soil vapor compounds of concern at potential source
areas. Based on the analytical results .of tests for VOCs and thirteen priority pollutant metals, the following six
contaminants were identified as the key contaminants:
• Chloroform; -
• cis-1,2-Dichloroethene (cis-1,2-DCE);
• Trans-1,2-Dichloroethene (trans-1,2-DCE);
• Trichloroethene (TCE);
• 1,1,2,2-Tetrachloroethane.(1,1,2,2-TeCA); and
• Tetrachloroethene (PCE).
The delineation of the horizontal extent of TCE and chloroform in shallow saprolite and the vertical extent of
chloroform in well clusters 'TW-2 and TW-10 occurred during Phase IV. Pilot tests of enhanced reductive
dechlorination (ERD) were conducted during September 2002 and March 2003, with the injection of sodium
lactate into the South plume and lactic acid in the North plume. Su bseq uent'sam piing events indicated" an
increase in reductive dechlorination in several wells.- To further reduce VOCs, EHC,Tm, a product of Adventus
1-1 December 2008

AECOM Environment
Americas Inc., was injected in two injection wells in the southern plume and four injection wells in the northern
plume during January 2005.
The CAP (ENSR, 2007) outlined a cost effective strategy to remediate and monitor the groundwater plume in a
manner that minimized adverse environmental impacts. Based on information collected during previous site
assessment activities and the ERD and EHCTM pilot tests, monitored natural attenuation (MNA) was
recommended as the most efficient and cost-effective remediation strategy. To demonstrate the effectiveness
of the proposed MNA program, the CAP required groundwater samples from 23 monitoring wells and 3
surface water locations to be collected semi-annually for 2 years and annually thereafter. In addition,
biogeochemical parameters will be monitored in 12 key wells on an annual basis.
1-2 December 2008

2.0 Methods
The subject sampling event was conducted between August 6 and 7, 2008. - ENSR personnel performed field
activities, including collection of groundwater samples, field measurement of water levels and geochemical
parameters. Well purging, sampling, and sample handling procedures were conducted according to ENSR,
NCDENR, and United States Environmental Protection Agency (EPA) Region IV protocols. Groundwater
sample collection records are included in Appendix A.
2.1 Sampling plan
In accordance with the groundwater monitoring program, the following monitoring wells are sampled:
North Plume
TW-4s
TW-4d
TW-4d2
South Plume
TW-2s
TW-10s
Surface Water
SW-1
TW-4d3 TW-6d2
EHCMW-4d2b TW-8d2
TW-5d TW-11 d2
TW-2d TW-2d2
TW-10d2 TWA Od3
SW-2 SW-3
TW-13s TW-14d4
TW-13d2
TW-13d3
TW-3d EHCMW-2s2
TW-12d2 PTMW-2SA
During the August 2008 sampling event, monitoring wells TW-2s and TW-10s were dry and groundwater
samples were not collected.
2.2 Groundwater sampling procedures
Prior to sampling, static groundwater levels were measured in each monitoring well. The wells were sampled'
with low -flow purge techniques using bladder pumps, or peristaltic pumps; refer to the sample collection
records (Appendix A) for the field methods used at each well location. The wells were purged by pumping at a
rate of 200 to 500 milliliters per minute (mUmin). Water levels were monitored approximately every five
minutes and a steady flow rate was maintained to stabilize the water level (drawdown of 0.3 feet or less). Field
parameters (temperature, pH, specific conductance, DO, and ORP) were measured to ensure collection of
representative groundwater samples. Each well was considered ready for sampling when field measured
parameters had stabilized to within 10% for three consecutive readings or if the well went dry. Field
parameters were recorded on field data sheets (Appendix A). After purging, groundwater samples were
collected at a flow rate between 100 and 350 ml/min.
2.3 Sample analysis
After purging, groundwater samples were collected for analysis. Sample handling, packaging, preservation
and storage were conducted in accordance with ENSR, NCDENR and USEPA protocols. Samples were
submitted under chain of custody control to Lancaster Laboratories in Lancaster, Pennsylvania for laboratory
analysis of the following:
• Chlorinated volatile organic compounds (CVOCs) by EPA Method 8260;
2-1 December 2008

• In addition, natural attenuation parameters consisting of nitrate, nitrite, ammonia, total iron, ferrous
iron, total and dissolved manganese, sulfate, sulfide, alkalinity, chloride, total organic carbon,
biochemical oxygen demand, chemical oxygen demand, and dissolved gases (ethane; ethene,
methane and carbon dioxide) analysis were submitted for eleven wells (North Plume wells TW-13s,
TW-13d2, TW-4s, EHCMW-4D2b, TW-4D2, and TW-4d3; South Plume wells PTMS-2Sa, TW-2d, TW-
2d2, TW-10d2, and EHCMW-2s2); and
• Field Parameters (DO, ORP, pH, temperature, and specific conductivity).
Surface water samples were analyzed for CVOCs by EPA Method 8260. A summary of analytical parameters
is provided at Table 1.

3.0 Results
3.1 Groundwater flow
Table 2 presents groundwater level gauging data. Consistent with previous data, groundwater flow in both the
shallow aquifer and partially weathered bedrock flows to the east toward Hominy Creek. The gradient in the
shallow saprolite and PWR aquifers was calculated at 0.045 ft/ft. Shallow and PWR potentiometric elevations
and contours are presented in Figures 3 and 4, respectively.
Well clusters constructed at TW-2, TWA TW-10, TW-11, TW-12, TW-13, and TW-14 were used to evaluate
the direction of intra-aquifer (vertical) flow between the shallow-saprolite (S), deep-saprolite (D), partially
weathered rock (D2), and bedrock (D3) aquifer zones. Upward vertical gradients were present during the
August 2008 sampling event at well pairs TW-4D2/TW-4D3, TW-11 s/TW-11 D2, TWA 2s/TW-12D2, and TW-
13D2/TVV-13D3. Downward vertical gradients were present at well pairs TW-2D2/TW-2D3,
TW10D2/TW10D3, TW-14s/TW-14D and TW-14D/TW-14D4. Table 3 summarizes the vertical gradients
observed during the current monitoring event.
3.2 Quality control/Data validation
The data package from Lancaster was reviewed for conformance to the requirements of SW-846 Test -
Methods for Evaluating Solid Waste Physical/Chemical Methods). The complete data validation report for the
August 2008 sampling event is presented in Appendix B. The data was validated by ENSR using the following
procedures:
• The list of analytical results was verified against chain -of -custody documentation to ensure that all
requested tests were performed and that the field identification number matched the identification on
the laboratory report;
• Date sampled and date analyzed were inspected -to ensure that required holding times were met;
• Surrogate spikes and duplicates were examined to verify that percent recoveries were within ranges
as specified by EPA SW-846;
• Dilution factors were checked to ensure that analytical results and detection limits were reported
correctly.
• Laboratory blank results were examined to ensure that samples were analyzed as specified by EPA
SW 846 protocols.
In general, the data are valid as reported and may be used for decision making purposes. Surrogate
recoveries for method SW846-8015B were outside of acceptable limits biased high in sample PTMW-2sA and
EHCMW-2s2. The samples were "J" qualified. The Data Validation report is provided as Appendix B.
3.3 Groundwater quality
VOC results for commonly detected compounds are summarized in Table 4 and historical laboratory results for
commonly detected compounds are presented at Table 5. Historical inorganic analytical results are presented
at Table 6 and historical field measured parameters for the wells sampled are listed in Table 7.

3.3.1 Comparison to previous results for VOCs
Overall, VOC concentrations are stable or decreasing as a result of natural attenuation and ERD pilot studies.
Below, changes in VOC concentration since the EHCTm injection in January 2005 are discussed by plume and
by aquifer. A historical summary of laboratory analytical results for site specific Compounds of Concern (COC)
is provided in Table 5.
North Plume Wells — Saprolite Interval
Concentrations of total VOCs in the four wells screened in the saprolite aquifer (TW-4s, TW-4d, TW-5d and
TW-13s) of the north plume have dropped by more than 90-percent since the January 2005. EHC.injection.
Concentrations of TCE still exceed the 2L standards in wells TW-13s, TW-4d and TW-4s. A summary of
laboratory analytical results for site specific COCs reported as part of the August 2008 sampling event is
provided at Table 4. A summary of historical groundwater concentrations is provided at Table 5.
3-2 December2008

AECOIVI Environment
North Plume Wells — PWR and Bedrock Interval
Concentrations of total VOCs in groundwater samples collected from wells screened in the bedrock interval of
the northern plume have decreased by greater than 90-percent since the January 2005 EHC injection.
However, concentrations of chloroform, PCE, TeCA and TCE still exceed their respective 2L Standard values
in one or more wells. A summary of laboratory analytical results for site specific COCs reported as part of the
August 2008 sampling event is provided at Table 4. A summary of historical groundwater concentrations is
provided at Table 5.
South Plume Wells — Saprolite Interval
Concentrations of total VOCs in the five'wells screened (EHCMW-2S2, TW-21D, TW2S, TW-31D and TW-10s)
in the saprolite aquifer of the south plume have dropped by greater than 80-percent since the January 2005
EHC injection. A summary of laboratory analytical results for site specific COCs reported as part of the August
2008 sampling event is provided at Table 4. A summary of historical groundwater concentrations is provided
at Table 5.
North Plume Wells — PWR and Bedrock Interval
Concentrations of total VOCs.in groundwater samples collected from wells screened in the bedrock interval of
the southern plume (TW-2D2, TW-10D2, TWA OD3 and TW-121)2) continue to show no impact above
respective 2L standard values for the six site specific COCs. A summary of laboratory analytical results for site
specific COCs reported as part of the August 2008 sampling event is provided at Table 4. A summary of
historical groundwater concentrations is provided at Table 5.
3.3.2 Comparison to model predictions
To determine the effectiveness of the EHC remediation, Bioscreen and Biochlor were used to model the
reductive dechlorination of TCE, chloroform and TeCA (see CAP -for details, ENSR, 2007). Separate models
were created for each plume, with the base concentrations from the January 2006 sampling event. In the
North plume, well TW-41D2 was used as the source area for groundwater contaminants; in the South plume,
EHCMW-2S2 was modeled as the source for TCE and TeCA, and TW-2S was modeled as the source for
chloroform.
TCE, chloroform, and TeCA concentrations predicted by the model are summarized below. By August 2008
concentrations of contaminants are significantly below modeled values. The following table summarizes actual
versus predicted contaminant concentrations for the August 2006, April 2007, April 2008 and August 2008
events.

3.4 Natural attenuation
To assess the intrinsic bioremediation potential of the CVOCs, groundwater samples were collected from
selected wells and analyzed for CVOCs and inorganic parameters including: nitrate, nitrite,ammonia, total
iron, ferrous iron, total and dissolved manganese, sulfate, sulfide, alkalinity, chloride, total organic carbon,
biochemical oxygen demand, chemical oxygen demand, ethane, ethene, methane and carbon dioxide:
Inorganic field parameters are summarized in Tables 6. Field measured parameters measured and recorded
in August 2008 are presented in Table 7. The following sections present an evaluation of the current
attenuation conditions in the North and South plumes.
North Plume
The primary line of evidence for attenuation of the North plume is the significant reduction in. plume extent
since the EHC injection event in January 2005. Figures 10 and 11 illustrate.the TCE plume in the shallow and
PWR/bedrock intervals for the period of November 2001 vs. August 2008, respectively. In addition, and as
discussed in Section 3.3.1, concentrations of site specific COCs have decreased by greater than 90-percent
since January 2605.
The groundwater geochemistry indicates a history of low DO, negative ORP, high ferrous iron, and methane,
which indicates the potential for continued anaerobic biodegradation at the site in its. current condition. The
presence of PCE daughter products indicates biodegradation is occurring beneath the site. A summary of
geochemi.cal and field measured parameters for the North Plume are presented at Tables 6 and 7,
respectively.

3.5 Surface water quality
Three surface water samples were collected during the August 2008 (SW-1, SW-2, SW-3) sampling events.
No VOCs were detected above laboratory detection limits. Laboratory analytical results are presented at
Appendix B.

4.0 Conclusions
The following conclusions and recommendations are based on the results of the August 2008 sampling event.
• Groundwater in August 2008 was flowing towards the east under a hydraulic gradient of 0.045 ft/ft in
the saprolite and PWR intervals.
• Upward vertical gradients were present during the August 2008 sampling event at well pairs TW-
4D2/TW-4D3, TW-11 s/TW-11 D2, TW-12s/TW-12D2, and TW-13D2/TW-13D3. Downward vertical
gradients were present at well pairs TW-2D2/TW-2D3, TW10D2/TW10D3, TW-14s/TW-14D and TW-
14D/TW-14D4. .
• The primary line of evidence for attenuation of the North plume is the significant reduction in plume
extent since the EHC injection event in January 2005. Concentrations of site specific COCs have
decreased by greater than 90-percent in North plume wells since January 2005.
• The primary line of evidence for attenuation of the South plume is the significant reduction in plume
extent since the EHC injection event in January 2005.
• Since 2000, the size and concentration of the deep saprolite TCE plumes have dropped significantly,
with 2L exceedences found only in the north plume.
• No VOCs were detected in the three surface water samples collected from Hominy Creek during the
August 2008 sampling event.
• The data presented within reaffirms that monitored natural attenuation is an effective remediation
strategy for this site.

greater than
ppm parts per million — One ppm is equivalent to one milligram per kilogram (mg/kg), or one gram per million grams.
For aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (mg/1), because one liter of
water has a weight very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter of
gas per liter of gas.
ppb - parts per billion
Dry weight Results printed under this heading have been adjusted for moisture content. This increases the analyte weight
basis concentration to approximate the value present in a similar sample without moisture.
U.S. EPA data qualifiers:
. Organic Qualifiers
A TIC is a possible aldol-condensation product
B Analyte was also detected in the blank
C Pesticide result confirmed by GC/MS
D Compound quatitated on a diluted sample
E Concentration exceeds the calibration range of
the instrument
J Estimated value
N Presumptive evidence of a compound (TICs only)
P Concentration difference between primary and
confirmation columns >25%
U Compound was not detected
X,Y,Z Defined in case narrative.
Inorganic Qualifiers
B Value is <CRDL, but >_IDL
E Estimated due to interference .
M Duplicate injection precision not met
N Spike amount not within control limits
S Method of standard additions (MSA) used
for calculation
U Compound was not detected
W Post digestion spike out of control limits

RE: Data Validation BASF ENKA August 2008
Date: September 12, 2008
File: BASF ENKA August2008 dv.doc
Project #: 00760-246-0003
Cc:
Limited validation was performed on one data package from Lancaster Laboratories in Lancaster, PA for water
samples collected on August 6, 2008. The samples were collected at the BASF ENKA site. The data were
reviewed for conformance to the requirements of SW-846 Test Methods for Evaluating Solid Waste
Physical/Chemical Methods. Lancaster processed the samples and reported the results under sample delivery
group (SDG) 1104473. The following analytical method was requested on the chains -of -custody (COCs) and/or
by the project manager:
•. SW846-8060B —Volatile Organic Compounds by Gas Chromatography/Mass Spectrometry (GC/MS).
Data were validated using the USEPA Contract Laboratory Program National Functional Guidelines for Organic
Data Review, July 2007.
Review Elements
Sample data were reviewed for the following parameters
• Agreement of analyses conducted with chain -of -custody (COC) requests,
• Holding times/sample preservation,
• Calibrations,
• Method blanks/equipment blanks/trip blanks,
• Laboratory control sample (LCS) results,
• Matrix spike/matrix spike duplicate (MS/MSD) results,
• Surrogate recoveries, and
• Field duplicate results.
Samples
ENSR collected the following samples included in this review:

Analytical Results
The data are valid as reported and may be used for decision making purposes. None of the data required
validation qualifiers.
DISCUSSION
Agreement of Analyses Conducted with COC Requests
Sample reports were checked to verify that the results corresponded to analytical requests as designated on the
COC. No discrepancies were noted.
Holding Times and Preservation
All samples were analyzed within the holding time required by the applicable method. The samples were
preserved properly. Sample coolers were within 4±2 °C, as required.
Tunes and'Calibrations
Gas chromatography -mass spectrometry tune summaries were not submitted for validation in this Level II data
package. Initial and continuing calibration data were not submitted for validation.

ppm parts per million - One ppm is equivalent to one milligram per kilogram (mg/kg), or one gram per million grams.
For aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (mg/1), because one liter of
water has a weight very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter of
gas per liter of gas.
ppb parts per billion
Dry_ weight Results printed under this heading have been adjusted for moisture content. This increases the analyte weight
basis concentration to approximate the.value present in a similar sample without moisture.

BASF ENKA—August2008 dv.doc
00760-253-0803
Limited validation was performed on one data package from Lancaster Laboratories in Lancaster, PA for water
samples collected on May 6, 2008. The samples were collected at the BASF ENKA site. The data were reviewed
for conformance to the requirements of USEPA Test Methods for Evaluating Solid Waste Physical/Chemical
Methods (SW-846), USEPA Methods for the Chemical Analysis of Water and Wastes (MCAWW), and Standard
Methods for the Examination of Water.and Wastewater (SM). Lancaster processed the samples and reported
the results under sample delivery group (SDG) 1104474. The following analytical methods were requested on the
chains -of -custody (COCs) and/or by the project manager:
• SW-846-8060B — Volatile Organic Compounds by Gas Chromatography/Mass Spectrometry (GC/MS),
• SW-846-8015B modified — Volatile Headspace Hydrocarbons,
• SW-846-6010B - Metals by Inductively Coupled Plasma Spectrometry/Mass Spectroscopy,
• SW-846-8000B — Carbon Dioxide,
• SM20 2320E —Alkalinity,
• EPA MCAWW 353.2 — Nitrate and Nitrite,
• SM20 4500NH3 — Ammonia,
EPA MCAW 300.0 — Chloride and Sulfate by Ion Chromatography (IC),
• SM20 4500 S2-D — Sulfide,
• SM20 5210E —Biochemical Oxygen Demand .(BOD),
• SM20 5310C.—Total Organic Carbon (TOD),
• EPA MCAWW 410.4 — Chemical Oxygen Demand (COD), and
• SM20'3500Fe — Ferrous Iron
Data were validated using the USEPA Contract Laboratory Program National Functional Guidelines for Organic
Data Review, July 2007 and USEPA Contract Laboratory Program National Functional Guidelines for Inorganic
Data Review, October 2004.
Review Elements
Sample data were reviewed for the following parameters:
•- Agreement of analyses conducted with chain -of -custody (COC) requests,
• Holding times/sample preservation,
• Calibrations,

Analytical Results
In general, the data are valid as reported and may be used for decision making purposes. The data was qualified
with "J" (estimated). See Table 1.
DISCUSSION
Agreement of Analyses_ Conducted with COC Requests
Sample reports were checked to verify that the results corresponded to analytical requests as designated on the
COC. No discrepancies were noted.
Page 2
2BASF ENKA_August2008dv September 2008

Holding Times and Preservation
All samples were analyzed within the holding time required by the applicable method. The samples were
preserved properly. Sample coolers were within 4±2 °C, as required for. all analyses.
Tunes and Calibrations
Gas chromatography -mass spectrometry tune summaries were not submitted for validation in this Level II data
package. Initial and continuing calibration data were not submitted for validation.
Blanks
No target analytes were detected at concentrations exceeding reporting limits in the laboratory blanks and trip
blanks.
Laboratory Control Samples
Laboratory control sample (LCS) and LCS duplicate (LCSD) sample analyte recoveries were acceptable for all
analyses.
Matrix Spike/Matrix Spike Duplicates
The matrix spike/matrix spike duplicate (MS/MSD) recoveries and precision were acceptable for all analyses with
the following exceptions.
Method 353.2: The matrix spike recovery for Nitrate and Nitrite were outside of the advisory limits biased low.
Data qualifiers were not required because the MS sample was not client -specific.
Surrogate Recoveries
The surrogate recoveries were acceptable for all analyses with the following exceptions:
Method SW846-8015B modified: The surrogate recoveries were outside of the acceptable limits biased high in
sample PTMW-2sA and EHCMW-2s2. The samples were qualified. See Table 1.
Field Duplicates
Field duplicates were not collected and submitted for analysis.
