1 Introduction

A groundwater and surface water assessment is ongoing at the former Wiley Davis
Landfill (Permit #41-B) located on Wiley Davis Road in Greensboro, North Carolina (see
Figures 1 and 2). The purpose of this assessment is to determine the presence, extent,
and concentration of contaminants present in groundwater and/or surface water, the
horizontal and vertical extent of contamination which may originate from the landfill, the
direction and rate of migration of the contaminants in the groundwater, and the possible
source(s) of contamination detected in the groundwater and/or surface water.

This assessment is being performed in accordance with the Water Quality Monitoring
Plan (Babb & Associates, P.A. and EcoLogic Associates, P.C. - Revised August 1999)
and the Groundwater Assessment Plan (Babb & Associates, P.A. and EcoLogic
Associates, P.C. - Revised August 1999). Since 2005 the sampling responsibilities have
been contracted with Waters Edge Environmental, LLC (Waters Edge).

Herein contains an account of the field sampling, laboratory analytical results and our
conclusions and recommendations for the site.

2 Groundwater Sampling Activities

2.1 Monitoring Well Sampling

On December 4th, 2014, a Waters Edge environmental technician was mobilized to the
site for the groundwater sampling activities. Prior to the sampling event, depth-to-
groundwater measurements were made to the nearest 0.01 foot at each monitoring well
using an electric water level indicator (see Tables 1 and 2).

Groundwater samples were collected from wells WD-1, WD-2, WD-2D, WD-3, WD-3D,
WD-4, WD-4D, WD-7, WD-8, and WD-9 (WD-8 mislabeled as WD-5 and WD-9
mislabeled as WD-6 in laboratory results). Groundwater samples were analyzed for volatile
organic compounds (VOCs) and tetrahydrofuran (THF) according to EPA Method 8260B
and total RCRA metals (EPA Method 6010 and 7470- see summary of analytical results in
Table 3 and documentation in Appendix A).

2.3 Surface Water Sampling

On December 4th, 2014, both upgradient (SW-1 see Figure 2) and downgradient (SW-2 see
Figure 2) surface water samples were collected and analyzed for VOCs and THF according

to EPA Method 8260B and total RCRA metals (EPA Method 6010 and 7470- see summary
of analytical results in Table 3 and documentation in Appendix A).

3 Assessment Results

3.1 Groundwater Conditions

On December 4th, 2014 water level measurements collected from the shallow wells
indicate the shallow water table elevations range from 816.84 feet (WD-7) to 786.86 feet
(WD-3) above mean sea level (msl). We would add that WD-2, WD-2D, WD-8 and
WD-9 have not been surveyed to add as a data point. The groundwater elevations
continue to indicate an overall southwesterly flow direction for shallow groundwater.
The horizontal hydraulic gradient of the shallow water table has an average gradient of
0.0164 ft/ft (see Figure 3)

The vertical gradient was calculated to be 0.0529 ft/ft downward between wells WD-3
and WD-3D and -0.0931 upward between wells WD-4 and WD-4D. We would also note
that WD-2/WD-2D have not been surveyed.

3.2 Groundwater Laboratory Analytical Results

Laboratory analysis of groundwater samples collected had the following exceedances of

 Chromium at 0.012 mg/L versus a NCGS at 0.01 mg/L
 Benzene at 2.1 mg/L versus a NCGS at 0.001 mg/L
 THF at 0.14 mg/L versus a North Carolina Occupational and
Environmental Epidemiology Branch Recommended 2L Standard of
0.0046 mg/L (there is no codified NCGS)
WD-2D This well had the following NCGS exceedances:
 Arsenic at 0.014 mg/L versus a NCGS at 0.01 mg/L
 Chromium at 0.031 mg/L versus a NCGS at 0.01 mg/L

3.3 Surface Water Laboratory Analytical Results

Low levels of one inorganic constituent was detected in upstream sampling point SW-1
(barium at 0.059 mg/L), and the downstream sampling point SW-2 had one inorganic
(barium at 0.15 mg/L); however, no applicable Class C surface water standards were
exceeded (15A NCAC 2B .0211).

4 Conclusions and Recommendations

Information gathered during groundwater assessment activities to date indicates the
general shallow and deep groundwater flow direction (horizontal gradient) beneath the
site to be to the southwest. Using a horizontal hydraulic gradient of 0.0164 ft/ft and
assuming an average hydraulic conductivity in saprolite of 1E-5 cm/sec and an effective
porosity of 0.25, the rate of horizontal groundwater migration would be on the order of
0.614 ft/year.

Now that the landfill is no longer active and has been graded to shed runoff and covered,
the infiltration of rainfall should be significantly reduced. It follows that the driving head
inside the landfill will gradually decline and both the quantity and rate of leachate
production and release should decrease proportionately. Leachate strength should also
continue to decline as the waste stabilizes, with no further introduction of potential
contaminants. Based on these recent results, we would conclude that a continued positive
trend in groundwater quality downgradient of the landfill has occurred.

There were several low level NCGS exceedances for arsenic, barium, cadmium, and
chromium. THF was also detected at low concentrations in five of the wells sampled
ranging from 0.14 mg/L (WD-2) to 0.14 mg/L (WD-4) which is above the interim NCGS
at 4.6 g/L. It was also detected in downgradient well WD-9 at 0.019 mg/L. Based upon

our research into THF uses, it appears one major use is for PVC pipe cement which could
have been mistakenly used in the older monitoring wells; however, in that it was also
detected in the recently installed monitoring wells, it must be included as a constituent of
concern. We would conclude the levels appear to be either stable or decreasing to below
NCGS with respect to time.

There were also several inorganic constituents detected in the newly emplaced
monitoring wells WD-8 and WD-9. Based on the total absence of VOCs, we would still
conclude that these are potentially due to sediment causing false positive readings. We
believe that with continued development and sampling that the inorganic constituents will
decrease. We would conclude that the plume is adequately defined horizontally.

Only one RCRA metal was detected in surface water samples (barium) at concentrations
well below the 2B standards. As such, we conclude that no measurable impacts to
surface water by VOCs or metals have been identified during this assessment.

Given the aforementioned conclusions, it is our recommendation to Wiley Davis Landfill,
Inc. that monitoring of the current system is continued on a semiannual schedule. This
next sampling event would be conducted in May 2015. We would also recommend that
WD-2, WD-2D, WD-8, and WD-9 be surveyed for both horizontal and vertical control.
