RE: Report of Results
Semi-Annual Groundwater and Surface Water Monitoring: May 2017
Nash County C&D Landfill
Nashville, Nash County, NC
Permit # 64-03

Dear Ms. Drummond:

This report presents the results of semi-annual groundwater and surface water quality
monitoring conducted at the C&D landfill site referenced above (Figure 1) in May 2017. The
scope of work performed included sampling and laboratory analysis of groundwater samples
from six on-site monitoring wells (MW-1 through MW-6) and surface water samples from two on-
site locations (SW-3 and SW-4). The groundwater and surface water samples were collected in
accordance with the NCDEQ, Division of Waste Management (DWM), Solid Waste Section
(SWS) Groundwater Monitoring Guidance Document and the facility Water Quality Monitoring
Plan. The sampling and data collection methods, as well as the current and historical results of
field and laboratory testing of the water samples, are presented in the following sections.

1.0 POTENTIOMETRIC PATTERN AND GROUNDWATER FLOW

Groundwater levels were gauged in the site groundwater monitoring wells on May 2, 2017 as
part of the site monitoring. Depths to groundwater were measured using an electronic water-
level meter that was thoroughly decontaminated between wells with a non-phosphate soap and
water wash followed in order by multiple rinses with distilled water, an isopropyl alcohol rinse,
and multiple distilled water rinses. Depth-to-water measurements were made after the wells
were opened for a sufficient period of time to allow water levels to equilibrate with atmospheric
pressure. The locations of the site monitoring wells are depicted in Figure 2. Groundwater
elevation data collected at the monitoring wells on May 2, 2017 are presented in Table 1. The
depth to groundwater across the site measured relative to the top of the PVC casing of the Type
II groundwater-monitoring wells on May 2, 2017 ranged from 19.00 feet (MW-2) to 41.33 feet

(MW-5), which is consistent with the surface topography. It is noted, however, that the depths to
groundwater measured in May 2017 were significantly higher than those measured in
November 2016.

A water-table elevation contour map that was developed based on the May 2, 2017
groundwater-gauging data for the Type II monitoring wells is presented as Figure 3. The
pattern of the water-table contours indicates that the horizontal component of shallow
groundwater flow at the site is generally to the northeast, which is consistent with the surface
topography and drainage features at the site. The delineated direction of shallow groundwater
flow is also consistent with previous estimates of groundwater flow direction at the site. The
hydraulic gradient of the water table, based on the data depicted in Figure 3, is approximately
0.025 ft./ft.

2.0 RESULTS OF GROUNDWATER AND SURFACE WATER SAMPLING AND ANALYSIS

Groundwater samples were collected from the site monitoring wells and surface water samples
were collected from two on-site locations on May 2 and 3, 2017 for laboratory analysis to
monitor the quality of groundwater and surface water at the site. It is noted that monitoring well
MW-1 serves as the up gradient, background well for the facility, and monitoring wells MW-2
through MW-6 serve as the down gradient monitoring wells. The groundwater and surface
water samples were collected and handled in accordance with the sampling protocols included
in the site Water Quality Monitoring Plan as well as the SWS Groundwater Monitoring Guidance
Document. Prior to groundwater sampling, monitoring wells MW-1, MW-2, MW-3 and MW-6,
were purged of stagnant water using pre-cleaned Teflon-lined disposable polyethylene tubing
connected to a peristaltic pump under low flow (≤ 200 ml/min) conditions. Monitoring wells MW-
4 and MW-5 were purged and sampled using disposable, bottom-loading PVC bailers. Surface
water samples were collected directly into sample containers by direct submersion in the
stream. All reusable sampling equipment was properly decontaminated between sampling
locations with a non-phosphate soap and water wash, followed by multiple rinses with distilled
water. New disposable nitrile or latex gloves were worn during all sampling activities.
Disposable sampling equipment/material (e.g., disposable bailers, gloves, etc.) was discarded
after each use.

During purging, measurements were made in the field of the pH, temperature, specific
conductance and turbidity of the groundwater collected from the monitoring wells, in accordance
with SWS requirements. The results of the field analyses of these parameters are presented in
Table 1. Copies of Groundwater Sampling Forms containing pertinent information recorded in
the field during purging and sampling at each groundwater monitoring well are presented in
Appendix A. The results of the field-measured water-quality parameters indicate that the
values measured in groundwater collected from the site monitoring wells were generally within
the applicable stabilization criteria with the exception of turbidity at monitoring well MW-4 which
– 3 – May 16, 2017

slightly exceeded 10 NTUs (16.2 NTUs). Groundwater at the site is acidic based on the pH
values measured in the field (4.17 to 5.19). Specific conductance values ranged from 34 (MW-
6) to 88 (MW-4) µS/cm and turbidity values ranged from 0.6 (MW-6) to 16.2 (MW-4) NTUs. It is
noted that groundwater in monitoring wells MW-4 and MW-5 was allowed to recover and settle
for approximately 24 hours before the final turbidity of the groundwater samples was measured
and the samples collected.

Surface water samples were collected from two locations at the site (SW-3 and SW-4). The
sampling locations are depicted in Figure 2. SW-3 is located approximately 1,200-feet
southeast (downstream) of the C&D Landfill along Pig Basket Creek. SW-4 is located upstream
where Pig Basket Creek runs under a bridge at State Road 1411. All surface water samples
were collected directly into sample containers by direct submersion in the stream in accordance
with the protocol presented in the SWS Groundwater Monitoring Guidance Document.

All groundwater and surface water samples were analyzed at a North Carolina-certified
laboratory for Appendix I volatile organic compounds (VOCs) by SW 846 Method 8260 and the
8 RCRA metals by EPA 6000/7000 series methods. Summarized results of laboratory analyses
for groundwater and surface water samples collected from the site in May 2017 are presented in
Table 2. Summarized historical groundwater and surface water quality data (from 2008 to
present) for the site are presented in Table 3. Copies of the original laboratory reports are
included in Appendix B.

The laboratory analytical results for the surface water samples collected from the site in May
2017 indicate that a trace concentration of acetone was detected in the sample collected from
sampling location SW-3 (5.2 µg/L, estimated). No other Appendix I VOCs were detected in
either sample. Low levels of arsenic, barium, chromium, lead, and selenium were reported in
both of the surface water samples and a trace level of cadmium was detected in sample SW-4.
Chromium was also detected in an associated laboratory blank sample. It is noted that none of
the reported concentrations of these metals in the surface water samples exceed the
corresponding 15A NCAC 2B surface water quality standards or the 15A NCAC 2L .0202
groundwater quality standards.

The laboratory analytical results for the groundwater samples collected from the site monitoring
wells in May 2017 indicate that a trace level of trichlorofluoromethane was reported in the
groundwater sample collected from monitoring well MW-4, and trace levels of acetone,
tetrahydrofuran and trichlorofluoromethane were reported in the groundwater sample collected
monitoring well MW-5. None of the reported concentrations of these volatile organic
constituents exceeds the corresponding 15A NCAC 2L .0202 groundwater quality standards.
No other Appendix I VOCs were reported in any of the groundwater samples.

The results of the metals analyses of the groundwater samples indicate that arsenic was not
detected in any of the samples, mercury and selenium were each reported in one of the
samples, silver was reported in two of the samples, and barium, cadmium, chromium and lead
were reported in all of the samples. Chromium was also detected in an associated laboratory
blank sample. None of the reported concentrations of RCRA metals in the groundwater
samples exceed the corresponding 15A NCAC 2L .0202 groundwater quality standards.

3.0 CONCLUSIONS AND RECOMMENDATIONS

The results of the May 2017 groundwater and surface water quality monitoring conducted at the
Nash County C&D Landfill are generally consistent with the results of previous monitoring
conducted at the site. No volatile organic compounds or RCRA metals were reported in any of
the groundwater or surface water samples at concentrations that exceed the corresponding 15A
NCAC 2L .0202 groundwater quality standards or 15A NCAC 2B surface water quality
standards.
