1.0 Introduction
During the week of May 23-25, 2022, US EPA’s Region 4 Laboratory Services and Applied Science Division (LSASD) personnel conducted a field investigation at the Benfield Industries Superfund Site in Hazelwood, North Carolina.
The collection of data from the sampling event is to be used in support of a Five-Year Review and in
assessing the viability of a monitored natural attenuation remedy or other actions for the site. Work was conducted in accordance with procedures outlined in the Sampling and Analysis Plan (SAP) dated April 18, 2022, and with the LSASD Field Services Branch (FSB) Site Safety Plan dated April 7, 2022.

Groundwater samples from 13 monitor well/ piezometer locations were collected, along with quality control (QC) samples. Samples were transported on ice back to the EPA laboratory in Athens, GA at the LSASD facility for analysis. Additionally, on-site analyses were conducted by an EPA chemist for ferrous iron and alkalinity utilizing the EPA mobile laboratory.
This report documents the 2022 groundwater sampling at the Benfield site, describes procedures, and presents analytical results. For a more complete evaluation of changes occurring over time at the site, results presented in this report can be compared to the reported results for past sampling events.
2.0 Summary

During the May 2022 event at the Benfield Industries Superfund Site, a total of 13 monitoring wells
and piezometers were sampled. The site had not been sampled by LSASD since 2014. The LSASD laboratory analyzed the samples for metals, volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), and natural attenuation indicators (VOCs and Classical Nutrients). Field chemistry analyses were also performed on-site for alkalinity and ferrous iron. Well PZ04 was not found and is assumed destroyed or covered over by a parking lot paving operation.
Based on the wells currently available to sample, the groundwater plume extent seems about the same as in 2014 or possibly smaller. The detections and exceedances of various volatile and semi-volatile compounds at the MW3SH, MW5S, PZ10 and MW5SH locations indicate that most of the remaining contaminant mass may still be concentrated in the central site area, with some apparent spreading
toward PZ10. Downgradient shallow well MW9A was sampled, and results showed no detections of volatiles or semi-volatiles. As in past years, manganese was detected in some samples with Tapwater Regional Screening Level (RSL) results over action limits. Four of the samples showed concentrations over the action level of
430 µg/L. Two showed concentrations about the same as in 2014 and two showed concentrations substantially higher. Lead concentrations in groundwater at the site are below the detection limit of 0.5 µg/L. The greatest number of different VOCs and SVOCs detected occurred in the MW3SH sample, as in
previous years. One detection of 1,4-dichlorobenzene exceeded the Tapwater RSL and the sample from PZ07 exceeded the Tapwater RSL action level for chloroform. No other VOC exceedances occurred in 2022. In 2013 and 2014, exceedances of the Tapwater RSL for vinyl chloride occurred at
LSASD Project ID 22-0163 Page 5 of 389
MW5S and MW5SH, but for 2022 the concentrations of vinyl chloride were below the RSL. The SVOC benzo(a)anthracene exceeded the Amended Record of Decision (ROD) remediation level and
the Tapwater RSL in three samples. 1,1 biphenyl, 1, methylnaphthalene, naphthalene, and
dibenzofuran concentrations exceeded the RSLs in the MW3SH sample. A bis(2-ethylhexyl) pthalate detection in the PZ07 sample exceeded the drinking water maximum contaminant level (MCL). That was the only MCL exceedance for 2022 and seems anomalous at six times the MCL.
Detections of classical nutrients and methane, along with field chemistry results and detections of
some VOCs and SVOC at lower concentrations than in 2014 may indicate that natural attenuation for some compounds is occuring at the site. Laboratory Method Reporting Limits (MRLs), and possibly some Method Detection Limits (MDLs), for various compounds were higher for 2022 than in past years and may obscure some lower-level detections.

3.0 Site Location and Background
The Benfield Superfund site is located in Hazelwood, Haywood County, North Carolina, near Waynesville, and occupies approximately 3 ½ acres of a 6-acre parcel. Figure 1, Site Location Map, shows the general location of the site. Figure 2, Monitor Well Location Map, shows the general site
layout and locations of wells and piezometers that were sampled during this event.
The site is currently occupied by an active facility known as Haywood Vocational Opportunity (HVO). The HVO facility provides employment for handicapped individuals. That building is indicated on Figure 2 by “HVO”.

In the past, the Benfield Industries, Inc. facility mixed and packaged bulk materials for resale. Products handled and stored at the facility included paint thinners, solvents, sealants, cleaners, de-icing solutions and wood preservatives, including creosote. The site was an active facility until April 1982, at which time a fire destroyed the majority of the structures and the entire operations. Several
State-lead investigations confirmed contamination of soil and groundwater. Following the 1982 fire,
all usable chemicals, fire debris, recyclable materials and storage tanks were removed. The July 1992 Record of Decision (ROD) documented the contamination of soils and groundwater.
Soils contained toluene, ethylbenzene, xylenes, benzo-a-anthracene, benzo-a-pyrene, benzo (B/K)
fluoranthene, chrysene, indeno (1,2,3-CD) pyrene, naphthalene, and pentachlorophenol. Groundwater contained benzene, chlorobenzene, 1,2-dichloropropane, vinyl chloride, xylenes, carbazole, benzo-a-anthracene, benzo-a-pyrene, benzo (B/K) fluoranthene, chrysene, indeno (1,2,3-CD) pyrene, naphthalene, pentachlorophenol, antimony, barium, beryllium, chromium, lead,
manganese, nickel and vanadium. The groundwater plume was previously shown to extend
approximately 100 – 200 feet off site. The original ROD was issued in 1992 and was amended in 1995. Another amended ROD was issued in September 2015, which presented a revised list of groundwater contaminants of concern and groundwater remediation levels (listed in 2022 Benfield SAP and in results tables).

During the 2014 sampling event, SESD (now LSASD) used a Trimble GPS unit to gather more accurate survey locations than those on file for some of the well locations. Those updated coordinates were used to plot the locations more accurately.

Note: Well MW9A is not shown on figure. It is located just off the image, about 297 ft north of MW8S.
LSASD Project ID 22-0163 Page 8 of 389
In the past, J. M. Waller abandoned wells MW2DP and MW2SH and replaced them with new wells
MW2DP-R and MW2SH-R, installed to about the same depth as the old wells. Lead detections
above action levels had been occurring in samples from well MW2DP but not in other site wells. Samples from the new well have not shown the lead results seen in the old well, indicating that something in the old well had been introducing the lead contamination.
Past groundwater elevations and mapping generally indicate flow to the northwest, from the MW3SH
area toward MW8SH. The 2022 groundwater measurements confirm that. Well PZ04 could not be located in 2022. The well was evidently covered or destroyed when a parking area was paved over at the adjacent Epsom Salts manufacturing facility. Table 1 shows the
wells sampled in May 2022 (PZ04 is included but could not be sampled) and lists various well
information and location coordinates. Table 2 provides additional well specifics, depth to water and potentiometric surface elevations.

4.0 Analytical Results 4.1 Analytical Methods Samples were analyzed in the LSASD laboratory for the following:

• Volatile Organic Compounds, EPA 8260C **
• Natural AttenuationVolatile Organic Compounds, (ethane, ethene, methane), MNA VOCs
(Method ASB V100)
• Semi-volatile Organic Compounds, Method EPA 8270E **
• Total Metals (Scan– No Mercury) (Methods EPA 200.8 and EPA 6010)
• Ammonia as N and Ammonia TKN (Methods EPA 350.1 and 351.2)
• Nitrate/ Nitrite (Method EPA 353.2)
• Total Organic Carbon (Method SM 5310B)
• Sulfate (Method EPA 300.0)
** To compare with past results and to achieve lower MRLs for various compounds, both VOC and SVOC analyses were requested using the Selected Ion Montoring (SIM) mode. However, the LSASD laboratory could not run the SIM analyses in 2022, resulting in higher MRLs than in past
years for most compounds.
LSASD Project ID 22-0163 Page 10 of 389
On-site chemical field analyses were conducted for natural attenuation parameters that included
ferrous iron and alkalinity (see below). Sulfides were not a field analyte during this investigation
because adequate supplies could not be obtained to conduct the field analysis. On-site analyses:
• Ferrous Iron (Field chemistry, Hach 8146)
• Alkalinity (Field chemistry, Hach 8203) 4.2 Laboratory Results

The results obtained from analyses by LSASD’s Laboratory Services Branch are discussed and
presented in the following sub-sections. Official laboratory reports and field chemistry reports are
included in Appendix B. The laboratory results were compared to both Regional Residential MCL-based Screening Levels for Chemical Contaminants at Superfund Sites November, 2021 (MCLs), and Regional Screening Levels for Chemical Contaminants in Tapwater at Superfund Sites November, 2021 (Tapwater RSLs). Where designated for particular analytes, Benfield Groundwater Amended
ROD action Levels were also used for comparison. Sample results can be compared to those from previous samplings to determine if any trends are indicated by changes in the detected analyte concentrations each year, or if these detections indicate that natural attenuation is occurring at the site. As in 2014, SIM method levels for VOCs and SVOCs were requested so that more accurate
comparison to past results could be made, but the LSASD laboratory was unable to provide those
lower method reporting limits (MRLs) for certain analytes. Care must be taken when comparing to past results to consider 2022 MRLs and MDLs that are higher for some compounds than in the past.
4.2.1 Metals

In summary, all samples showed detections of barium, sodium, strontium, calcium and magnesium.
Concentrations that exceeded Tapwater RSL levels, occurred only for manganese. All but three samples had detections of manganese, with concentrations ranging from 15 µg/L to 7100 µg/L. Samples from wells MW5S, MW5SH, MW8SH, and PZ10 had manganese concentrations over the 430 µg/L action level for tapwater. All but one sample showed concentrations at or over the reporting
limit of 1000 µg/L for potassium. Iron was also present in most samples, with the highest
concentration being 10,000 µg/L (the same as in 2013 and 2014). As in 2014, only one of the 13 samples (from PZ10) contained zinc over the reporting limit of 10 µg/L. Aluminum was detected in the MW9A sample at 200 µg/L. Metals results for the 13 groundwater samples are presented in Table 3. Shaded cells indicate detections, and exceedances are bolded.

4.2.2 Volatile Organic Compounds
Fourteen different VOCs were detected in samples, with the greatest number of different compounds detected in the MW3SH sample, as in previous years. The MW3SH sample showed detections of 11 of the 14 volatile compounds detected site-wide. The MW3SH sample was followed by MW5S and
MW5SH having the next-highest number of compounds detected, at five. The PZ10 well sample
showed detections of four different compounds. The MW3SH sample showed a detection of 1,4-dichlorobenzene (1.8 µg/L, estimated value), that exceeded the Tapwater RSL. However, detections of 1,4-dichlorobenzene were at a lower concentration in the 2022 MW3SH sample than in the

2014 sample. The sample from PZ07 exceeded the Tapwater RSL action level for chloroform (at 0.29 µg/L). Samples not showing volatiles detections at or above the 2022 MRLs included those from
MW2DP-R, MW3S, MW9A, PZ09 and EXT03. Samples from wells MW2SH-R and MW8S
showed only detections of methane. The overall number of detections and exceedances was down from 2014. In 2013 and 2014, exceedances of the Tapwater RSL for vinyl chloride occurred at MW5S and MW5SH, but for 2022 the concentrations of vinyl chloride were below the RSL.
Table 4 presents a summary of volatile organic compounds detected in the May, 2022 samples, and
includes Amended ROD levels and other action-level comparison values. Shaded cells indicate detections; bold values indicate exceedances. Appendix B includes copies of the Laboratory reports detailing the volatiles analysis, all analytes, detections, and all related qualifiers.

4.2.3 Semi-Volatile Organic Compounds Table 5 presents a summary of semi-volatile organic compounds detected in the May, 2022 samples.
Sixteen different semi-volatile compounds and five tentatively identified compounds (TICs) were
detected in various combinations in samples. Shaded cells indicate detections, and values in bold indicate Tapwater RSL or ROD exceedances. Values in bold red text indicate exceedance of the MCL for that compound. One well sample, from PZ07, showed only the SVOC detection of biz(2 ethylhexyl) phthalate (at 61 µg/L), which happened to be over the MCL of 6 µg/L. This detection
seems anomalous based on past samplings, and may not be representative of the groundwater. Future
sampling(s) may provide confirmation this analyte or help show that it is not representative. In summary, samples collected from six wells, MW3SH, MW5S, MW5SH, MW8S, MW8SH, and PZ10, had detections of one or more semi-volatile compounds (includes 5 TICs). Volatile compounds were also detected in most of those wells (see Table 4). Compounds detected included
methylnaphthalene, benzo(a) anthracene, fluoranthene, carbazole, chrysene, fluoranthene, fluorene, naphthalene, dibenzofuran, and pyrene, among others. MW3SH had the greatest number of compounds detected, including 19 of the 21 detected compounds (including TICs). Detections of 1,1- biphenyl and naphthalene were at lower concentrations in the 2022 MW3SH sample than in 2014. The MW5SH sample had the next-highest number of compounds detected, at 5 (half as many
as in 2014), and the PZ10 sample next, with 4 compounds detected. Pyrene was detected in six of the 13 well samples (and in the duplicate), ranging from 4.4 µg/L to 17 µg/L (from MW3SH). The sample from PZ10 showed detections of pyrene at 11 µg/L (up from 2013 and 2014). In 2014 an exceedance for chrysene at almost twice the 1992 ROD action level of 0.2 µg/L occurred in the sample from well MW5SH, but in 2022 chrysene was not detected at the MRL of 2 µg/L.
4.2.4 Natural Attenuation Indicators: Classical Nutrients Results for Classical Nutrient Natural Attenuation analytes are shown in Table 6. Shaded cells indicate detections. Samples showed detections of some combination of two to four of the five analytes (some values were estimated, as indicated by laboratory qualifiers). The detections of these
compounds may indicate that natural attenuation is continuing to occur at the site.

4.2.5 Natural Attenuation Indicators: Organics
Sample results were obtained for ethane, ethene, and methane as indicators for chemical reactions related to natural attenuation. Ethane and ethene were not detected in any of the samples above the reporting limit of 2.4 µg/L, and are therefore not shown in a table. Methane was detected in seven of the thirteen samples (and in the duplicate), and concentrations ranged from 13 µg/L (MW8S) to 920 µg/L (MW5SH). Results
for the duplicate sample from MW5S (22 µg/L) compared exactly with the MW5S sample results (22 µg/L), with zero percent difference. The results for methane detections are included in Table 3, Volatile Organic Compound Results. The production of methane at these locations may indicate that natural attenuation chemical reactions are occurring at the site.

5.0 Field Methodology
During the May, 2022 event, a total of 13 monitoring wells and piezometers were sampled. Sample names and well construction specifications, including well depth, casing diameter, and screened intervals are included in Tables 1 and 2.
This investigation was conducted in accordance with the Quality Assurance Project Plan on file, the
Sampling and Analysis Plan (SAP) dated April 18, 2022, “Sampling and Analysis Plan, Benfield
Industries)”, and the Region 4 LSASD, “Field Branches Quality System and Technical Procedures”, most recent versions. The following specific procedures were used during the collection, handling and shipment of samples for this investigation:

5.1 Water Level Measurements
Just prior to sampling, wells were opened and allowed to equalize before the depth to water from top of
casing was measured in each with an electronic water level indicator. Measurements were made in accordance with SESDPROC-105-R4, Groundwater Level and Well Depth Measurement, and recorded in the field logbooks. Drawdown levels during purging were also measured and recorded. The water level probe was decontaminated after use at each location to avoid cross-contamination. Table 2 lists top-of-
casing elevations (revised in 2012), water level measurements made on the day of sampling, and water
table surface elevations based on the revised top-of-casing elevations for the 13 wells.
LSASD Project ID 22-0163 Page 20 of 389
5.2 Well Purging and Sample Collection Unless otherwise noted in logbooks, groundwater samples were collected according to SESDPROC-301-R5, Groundwater Sampling. Locations of the wells sampled are shown in Figure 1, Monitor Well Locations. Table 1, Well Information and Sample IDs, lists the wells that were sampled, sample names,
well depths, and casing diameters. Table 2, Additional Well and Aquifer Information, includes the
measurements to water surface from the top of the casings and the calculated potentiometric water surface elevations. In previous years, wells were purged using the three-volume method. This year, wells were purged and
sampled using the low flow method. A peristaltic pump with a piece of MasterFlex tubing running through
the pump mechanism was connected to Teflon tubing placed in the approximate mid-screen area of the well. Purging continued until parameters stabilized, and then samples were collected. If drawdown was more than 1 foot below the measured static groundwater level, then the pump rate was slowed to try and match the recovery rate of the well. The purging was documented in the logbooks (in Appendix A) by
keeping a record of the volume of water removed from the well bore, times of readings, depth to water
during pumping, and readings for temperature, pH, specific conductivity, turbidity, oxidation-reduction potential (ORP), and dissolved oxygen (DO). As purging was conducted, water was discharged into an over-topping container fastened to the rim of a graduated bucket. The tips of probes were inserted into the overtopping container for constantly updated measurements. Purge water collected in the buckets was
disposed of on the ground at the site. Table 8 lists the final field parameter readings recorded before
sampling. Purging was considered complete when field parameters had stabilized for at least three separate readings, and turbidity was less than 10 NTUs. Water from most of the wells at the conclusion of purging was very
clear, with all turbidity readings at less than 10 NTUs. Water from six of the wells showed turbidity
readings of less than 1.0 NTU, water from four wells read between 2 NTU and 4 NTU, and samples from two wells read between 7 NTU and 9 NTU. Samples were collected for metals analysis first, by filling containers directly from the discharge side of the
pump head. After that, containers for Nitrates/ Nitrite/Ammonia, total organic carbon, sulfate, ferrous iron,
and alkalinity analyses were collected in the same manner. Following that, transfer cap assemblies were placed on one-liter amber bottles so that the pump could be used to create a vacuum to pull the semi-volatiles sample into the bottle without the water’s passing through the pump head. Lastly, samples for volatile organic compounds and SIM volatile organic compounds were collected by filling the intake tube,
stopping the pump, pulling the tube from the well while still attached to the pump head, reversing the pump
drive, and operating the pump at a very slow rate to push water back out of the tube and into 40 milliliter volatile vials so that water did not pass through the MasterFlex tubing and the pump head, and no-headspace filling could be achieved.
The metals samples were preserved with nitric acid and nitrite/ammonia samples were preserved with
sulfuric acid. Volatiles vials were pre-preserved with four drops of concentrated hydrochloric acid. Containers used and preservative requirements are listed in the field logbooks.

transportation to the laboratory. Samples for field analysis were hand-delivered to the field chemist for
prompt analysis. Sixteen samples were transported to the EPA laboratory in Athens, GA for analysis (13 well samples, 1 duplicate sample, 2 trip blanks). Trip blank samples were only analyzed for Volatile Organic Compounds.

In past years, purging for recovery well EXT03 was conducted differently than for the 2-inch diameter wells because of the greater 3-casing purge volume (201 gallons) for the 8-inch casing diameter. A submersible pump was previously used for purging EXT03 by removing a port in the top of the plate covering the casing opening and lowering the pump and discharge hose into the water column. Because of the low-flow sampling technique used in 2022, the submersible pump was not needed. Instead, a
peristaltic pump with clean Teflon tubing inserted into the well screen was set up and used for sampling EXT03. The same sampling procedures were then used for EXT03 as for the other wells.
LSASD Project ID 22-0163 Page 22 of 389
5.2.1 Sample Identification Nomenclature Samples were identified by adding a dash and “0522” to the station ID, designating the sample as being collected during the May, 2022 event (Station ID: MW3SH; Sample ID: MW3SH-0522). Table 1 lists station IDs and sample numbers for the monitoring wells.

Groundwater samples from 13 monitor well / piezometer locations were collected, along with one duplicate sample (designated as MW05S-0522D), two trip blanks for VOC sample shipments (designated as TB01-0522 and TB02-0522), and extra volume for a matrix spike/ matrix spike duplicate (MS/MSD) for quality control purposes (same designation as the sample – PZ09-0522).

5.3 Field Logbooks
Standardized logbooks were used on site to keep accurate records of sampling activities, procedures, dates, samples collected, purge volume, and to record field parameters used to indicate stability of water being pulled into the well from the formation, etc. Copies of these logbooks are included in Appendix A. Logbooks were also used to record procedures and results for field analyses performed and for daily
instrument calibration (included in Appendix A).
5.4 Field Analyses
Field analytical equipment was set up inside the LSASD mobile laboratory. Groundwater samples were collected from each of thirteen wells and stored on ice in the mobile lab each day until analyzed. Samples were analyzed for the presence of ferrous iron and alkalinity. Samples for ferrous iron and alkalinity analysis were collected in a 500mL container with no headspace or preservative. Aliquots were
taken to measure for ferrous iron (Hach Method 8146)—using both the Hach DR2010 and the Hach
DR2800 Spectrophotometer. Aliquots for alkalinity (Hach Method 8203) were also taken from the 500mL container and were titrated using a Hach digital titrator to determine total alkalinity. Hach instruments, digital titrators, pipettes, etc. used in these procedures are described and documented in the field analysis logbooks, included in Appendix B, in Table 6, and / or Field Chemistry Summary, included in Appendix B.

6.0 Quality Control Consistently following proper field procedures to ensure sample integrity and to prevent cross-contamination is important for maintaining quality results. These procedures are strictly followed by LSASD. Care and calibration of field instruments are also strictly adhered to. Methods used for
maintaining and documenting standards of quality control in the field during sample collection, sample
storage, transfer and transport, and in the laboratory during storage and analysis are described below.
LSASD Project ID 22-0163 Page 23 of 389
6.1 Samples Field quality control measures were conducted in accordance with the SESD Operating Procedure for Field Sampling Quality Control, LSASDPROC-011-R6, and/or 40 CFR Part 136.3, Table II-Required Containers, Preservation Techniques, and Holding Times, as applicable.

The number and type of field quality control samples utilized for this investigation were as follows: • VOC Trip Blank(s) for each shipment, as needed (two were shipped) • One duplicate (one per 20 samples) • One Matrix spike/matrix spike duplicate analysis (one per 20 samples) • Temperature blanks with each iced sample cooler to indicate shipping temperature. • Field Laboratory QC Volatile Organic Compound Trip Blank
Two volatile organic compound trip blanks, samples TB01-0522 (5/25/022) and TB02-0522 (5/25/022), were prepared at the LSASD laboratory and were transported and maintained in close proximity to the monitoring well samples during all phases of sample collection and transport back to the LSASD laboratory. Laboratory analyses for all compounds were performed on the samples, and none of those
compounds were detected in the trip blanks. Results showing no detections at or above detection limits indicates that there were no outside sources of contamination that may have cross-contaminated samples during the sample collection and transportation process. Analysis results are included in laboratory reports in Appendix B.

Field Duplicate Sample The field duplicate sample was collected at station MW05S. The primary sample was identified as MW5S-0522 and the duplicate was identified as MW5S-0522D. Duplicate analyses results are included in Tables
3, 4, 5 and 6, and in Laboratory Reports Appendix B. Comparison of the results for the two samples reveals close, acceptable concentration values for all analytes except for two of the natural attenuation indicators (ammonia and Kjeldahl nitrogen).
As a quality check, the following formula can be applied to the sample result and the duplicate sample
result to determine relative percent difference between the two values: |Analyte value – duplicate value| ______________________________________ X 100 = relative percent difference (RPD) Average of Analyte value + duplicate value The formula is basically the absolute value of the difference between analyte and duplicate divided by the average of the two, times 100. Out of 14 compounds detected and reported as sample and duplicate for the categories for VOCs, SVOCs, and metals, 13 were at 10% RPD or less, 9 were at 5% RPD or less, 4 were the same, or 0% RPD, and only one was above 10 % RPD, at only 12.3 % RPD. It can be discerned from
LSASD Project ID 22-0163 Page 24 of 389
these comparison numbers that sample collection and handling procedures were consistent, field techniques were excellent, and that the laboratory performance and analysis repeatability was excellent. Matrix Spike / Matrix Spike Duplicates Extra sample volume was collected for sample PZ09-0522 and designated for matrix spike/ matrix spike duplicates (MSMSD). The laboratory performed quality control tests on these samples with favorable
results, as documented in lab reports contained in Appendix B.

Temperature blanks Temperature blanks were included in each sample cooler when transported. These blanks were checked
when arriving at the lab to document that sample temperatures were kept at 4 degrees Centigrade or lower.
Samples were then transferred to the EPA refrigerated sample storage locker until extracted and/ or analyzed. Results indicated that samples had been properly chilled. Sample custody room check-in sheets are included in Appendix C.
Field Laboratory QC
Quality control for the field laboratory procedures was conducted in accordance with recommended QC for the methods and instrumentation used. At least one duplicate analysis was conducted, per the method and analytical requirements. Those procedures are documented in the field chemistry logbooks included in
Appendix B. Standard field laboratory QC measures are documented in the LSASD laboratory report(s)
provided in Appendix B.
6.2 Instrument Calibration Field instruments were calibrated each morning according to manufacturers’ specifications, using fresh standard solutions where applicable. Instrument calibration was verified at the end of the day as an
accuracy reference. In the event that an instrument indicated a problem or malfunction, then that instrument would be replaced with a different calibrated instrument. Instruments used by each sample team and details of calibration and QC checks are noted in the instrument calibration logbook (Appendix A). 6.3 Chain of Custody Documentation

Official chain of custody forms were completed, signed, transported with sample coolers, and signed when submitted to the LSASD sample custody room to document that the samples were delivered without incident. Copies of those forms are included in Appendix C.

7.0 Discussion and Conclusions

For 2022, detections of thirty-five different organic compounds (including methane and 5 TICs) were reported by the LSASD laboratory, with exceedances occurring for two different volatile organic compounds (five in 2013, ten in 2014) and six different semivolatile compounds. Based on the analytical

results of the 13 samples and one duplicate sample, the most contaminated well, with respect to number of organic compounds and the respective concentrations, was MW3SH, followed by MW5SH (a similar result
was noted for the 2012, 2013 and 2014 samplings). Twenty-five different organic compounds, plus five
TICs, were detected in the MW3SH-0522 sample. Four compounds in that sample exceeded the Tapwater RSLs. Both the ROD action level and the Tapwater RSL were exceeded for benzo(a) anthracene in three samples. An anomalous detection of biz(2-ethylhexyl)phthalate occurred in the PZ07 sample at 61 µg/L(six times the MCL). Sample MW3SH-0522 showed detections for eight different metals, but with no
exceedances (manganese was detected only at 72 µg/L). Four other samples did exceed the Tapwater RSL
for manganese. Those more contaminated wells are screened in the (approximate) 5ft. to 15 ft. depth zone and are more or less centrally located within the site and relatively close to the existing HVO building. The shallowness and the relatively small area of the more contaminated zone could make any future remedial designs easier to implement.
Table 9 lists various wells, and some of the compounds which have showed a detection exceeding an action level (all exceedances shown in red), for the years 2012, 2013, 2014 and 2022. Table 9 lists either the ROD action levels and the regional tap- water screening levels, or the tapwater and MCL levels, depending on whichever two are applicable and /or have lower action levels, for comparison. The table
allows one to quickly see wells where most exceedances have been occurring and allows a quick
comparison of those from 2012 forward. Some other compounds, such as pyrene, have also been detected at various wells over time, but those typically have not been detected in concentrations exceeding action levels, and are not shown in Table 9. Evaluating and comparing those detections as well may help understand the distribution of contaminants at the site and potential trends in natural attenuation.

Groundwater elevations (based on the limited number of wells) generally indicate flow to the northwest, from the MW3SH area toward MW8SH. Concentrations of organic compounds and manganese at MW8SH and MW8S in 2012 - 2014 indicated that contamination (acenapthene, benzo(a)anthracene, fluorene, fluoranthene, pyrene, vinyl chloride, dichlorobenzene, manganese, and chlorobenzene) was
migrating toward MW8SH. The samples collected in 2022 show only detections of pyrene and an
estimated amount of chlorobenzene at that location (based on 2022 MRLs). Also, several compounds detected in the MW3SH sample this year were at lower concentrations than in 2014. Those include naphthalene, dibenzofuran, and 1,4 dichlorobenzene. Those changes, along with methane detections at various locations, could indicate progress of natural attenuation since 2014.

The 2022 sample from further downgradient MW9A showed no detections of volatiles or semivolatiles at or above the MRLs. The lack of detections at MW9A may indicate that the plume has not migrated that far. However, MW9A is only 12 feet deep and does not show the condition of deeper zones.
Methane detections, along with other classical nutrient concentrations (see section 4.2.1) at various wells
may indicate chemical breakdown and natural attenuation in progress. To more completely delineate the plume, a few additional wells could be installed. A sampling point between MW5SH and MW8SH would be helpful. That well could be located at the northwest corner of the
paved HVO parking lot, north of MW5SH. Additionally, with the loss of PZ04, a shallow well in the 15 to
16 foot depth range near PZ10 would be helpful. PZ10 is 27 feet deep, but most of the more concentrated contamination detected around the site seems to occur in the 14 – 16 foot depth range, based on current well sampling results.

ACRONYMS AND ABBREVIATIONS
CAS Chemical Abstracts Service
Note: Analytes with no known CAS identifiers have been assigned codes beginning with "E", the EPA ID as assigned by
the EPA Substance Registry System (www.epa.gov/srs), or beginning with "R4-", a unique identifier assigned by the EPA
Region 4 laboratory.
MDL Method Detection Limit - The minimum concentration of a substance (an analyte) that can be measured and
reported with a 99% confidence that the analyte concentration is greater than zero.
MRL Minimum Reporting Limit - Analyte concentration that corresponds to the lowest demonstrated level of acceptable
quantitation. The MRL is sample-specific and accounts for preparation weights and volumes, dilutions, and
moisture content of soil/sediments.
TIC Tentatively Identified Compound - An analyte identified based on a match with the instrument software's mass
spectral library. A calibration standard has not been analyzed to confirm the compound's identification or the

Note: Analytes with no known CAS identifiers have been assigned codes beginning with "E", the EPA ID as assigned by
the EPA Substance Registry System (www.epa.gov/srs), or beginning with "R4-", a unique identifier assigned by the EPA
Region 4 laboratory.
MDL Method Detection Limit - The minimum concentration of a substance (an analyte) that can be measured and
reported with a 99% confidence that the analyte concentration is greater than zero.
MRL Minimum Reporting Limit - Analyte concentration that corresponds to the lowest demonstrated level of acceptable
quantitation. The MRL is sample-specific and accounts for preparation weights and volumes, dilutions, and
moisture content of soil/sediments.
TIC Tentatively Identified Compound - An analyte identified based on a match with the instrument software's mass
spectral library. A calibration standard has not been analyzed to confirm the compound's identification or the
estimated concentration reported.

J The identification of the analyte is acceptable; the reported value is an estimate.
QM-1 Matrix Spike Recovery less than method control limits
ACRONYMS AND ABBREVIATIONS
CAS Chemical Abstracts Service
Note: Analytes with no known CAS identifiers have been assigned codes beginning with "E", the EPA ID as assigned by
the EPA Substance Registry System (www.epa.gov/srs), or beginning with "R4-", a unique identifier assigned by the EPA
Region 4 laboratory.
MDL Method Detection Limit - The minimum concentration of a substance (an analyte) that can be measured and
reported with a 99% confidence that the analyte concentration is greater than zero.
MRL Minimum Reporting Limit - Analyte concentration that corresponds to the lowest demonstrated level of acceptable
quantitation. The MRL is sample-specific and accounts for preparation weights and volumes, dilutions, and
moisture content of soil/sediments.
TIC Tentatively Identified Compound - An analyte identified based on a match with the instrument software's mass
spectral library. A calibration standard has not been analyzed to confirm the compound's identification or the
estimated concentration reported.

ACRONYMS AND ABBREVIATIONS
CAS Chemical Abstracts Service
Note: Analytes with no known CAS identifiers have been assigned codes beginning with "E", the EPA ID as assigned by
the EPA Substance Registry System (www.epa.gov/srs), or beginning with "R4-", a unique identifier assigned by the EPA
Region 4 laboratory.
MDL Method Detection Limit - The minimum concentration of a substance (an analyte) that can be measured and
reported with a 99% confidence that the analyte concentration is greater than zero.
MRL Minimum Reporting Limit - Analyte concentration that corresponds to the lowest demonstrated level of acceptable
quantitation. The MRL is sample-specific and accounts for preparation weights and volumes, dilutions, and
moisture content of soil/sediments.
TIC Tentatively Identified Compound - An analyte identified based on a match with the instrument software's mass
spectral library. A calibration standard has not been analyzed to confirm the compound's identification or the
estimated concentration reported.

U The analyte was not detected at or above the reporting limit.
J The identification of the analyte is acceptable; the reported value is an estimate.
QR-1 MRL verification recovery less than lower control limits.
ACRONYMS AND ABBREVIATIONS
CAS Chemical Abstracts Service
Note: Analytes with no known CAS identifiers have been assigned codes beginning with "E", the EPA ID as assigned by
the EPA Substance Registry System (www.epa.gov/srs), or beginning with "R4-", a unique identifier assigned by the EPA
Region 4 laboratory.
MDL Method Detection Limit - The minimum concentration of a substance (an analyte) that can be measured and
reported with a 99% confidence that the analyte concentration is greater than zero.
MRL Minimum Reporting Limit - Analyte concentration that corresponds to the lowest demonstrated level of acceptable
quantitation. The MRL is sample-specific and accounts for preparation weights and volumes, dilutions, and
moisture content of soil/sediments.
TIC Tentatively Identified Compound - An analyte identified based on a match with the instrument software's mass
spectral library. A calibration standard has not been analyzed to confirm the compound's identification or the
estimated concentration reported.
