October 2014 Semi-Annual Monitoring S&ME Project No. 1356-07-006
Lincoln County Owl’s Den Landfill December 5, 2014

1.0 INTRODUCTION
S&ME, Inc. (S&ME) was contracted by Lincoln County to provide groundwater, surface
water, and water supply well monitoring services at the Owl’s Den Landfill located off
Owl’s Den Road in Lincolnton, North Carolina. This semi-annual monitoring event was
conducted on October 9 and 10, 2014.

This report presents the results of the second semi-annual sampling event for the year
2014 at the facility, which included the sampling of one (1) background well (MW-1), ten
(10) compliance wells (MW-2, MW-4, MW-5, MW-6, MW-6A, MW-7, MW-7A, MW-8,
MW-9, and MW-10), three (3) surface water locations (SW-1, SW-2 and SW-3), and four
(4) private supply wells (PSW-1, PSW-3, PSW-6, and PSW-16).

Surface water location SW-1 represents the background surface water sample for the site.

Please note that compliance well MW-3 has been removed from the site’s monitoring
plan due to expansion of the property boundary currently monitored by compliance wells
MW-8 and MW-9. Compliance monitoring well MW-3 remains on-site for water level
measurement purposes.

Lincoln County personnel collect monthly landfill gas readings at seven (7) methane
monitoring wells (MMW-2, MMW-4, MMW-5, MMW-6, MMW-7, MMW-8, and
MMW-9). Please note that methane monitoring wells MMW-1 and MMW-3 have been
removed from the site’s monitoring plan. MMW-1 was replaced with MMW-7, and
MMW-3 was replaced with MMW-5 and MMW-6. This report includes the results (both
current and historical) of the Site’s landfill gas monitoring.

The next sampling event is scheduled for April 2015.
2.0 GROUNDWATER LEVELS AND FLOW DATA
The water table elevations and our interpretation of the groundwater surface expressed as
a potentiometric map along with groundwater flow direction are shown on Figure 1.
Based upon the groundwater elevations in the vicinity of the landfill, groundwater in this
area is projected to flow north-northwest toward the drainage features bordering the site
on the west, north and east of the property. Groundwater levels obtained during the
October 2014 monitoring event, as well as monitoring well construction data, are
presented in Table 1.

The hydraulic gradient (i) in the vicinity of each well was determined by calculating the
vertical difference between the groundwater elevation at each well and one or more
nearby contour lines from the Groundwater Elevation Map. This value was then divided
by the distance measured from the well to the selected groundwater elevation contour
line. Groundwater velocity was calculated by multiplying the gradient (i) by the
hydraulic conductivity (k) and dividing by the estimated effective porosity (ne) of the
aquifer. Table 2 summarizes the groundwater flow velocities for the monitoring wells.

3.0 ANALYTICAL DATA
Analytical results for the landfill monitoring wells, surface water locations, and private
supply wells are summarized in Tables 4 through 6. Field measurements of pH,
conductivity, and temperature are summarized in Table 3. Well sampling logs containing
this information are included in Appendix I. The monitoring wells and surface water
stations were sampled for volatile organics by EPA Method 8260B and for RCRA metals.
3.1 Monitoring Well Sampling

No volatile organic compounds (VOCs) were detected in the background monitoring
well, MW-1, or monitoring wells MW-5 or MW-10.

Nine (9) VOCs were detected in monitoring well MW-2, none of which were detected at
a level at or above their respective NCAC 2L .0202 Groundwater Quality Standard (2L
Standard) and/or respective SW GWP Standard.

Ten (10) VOCs were detected in monitoring well MW-4, three (3) of which were
detected at levels at or above their respective 2L Standard and/or respective SW GWP
Standard (1,2-Dichloroethane, 1,4-Dichlorobenzene, and Benzene).

Seven (7) VOCs were detected in monitoring well MW-6, none of which were detected at
or above their respective 2L Standard and/or respective SW GWP Standard.

Seven (7) VOCs were detected in monitoring well MW-6A, one (1) of which was
detected at or above its respective 2L Standard and/or respective SW GWP Standard (1,4-
Dichlorobenzene).

Eight (8) VOCs were detected in monitoring well MW-7, none of which were detected at
or above their respective 2L Standard and/or respective SW GWP Standard.

Seven (7) VOCs were detected in monitoring well MW-7A, none of which were detected
at or above their respective 2L Standard and/or respective SW GWP Standard.

Two (2) VOCs were detected in monitoring well MW-8, none of which were detected at
or above their respective 2L Standard and/or respective SW GWP Standard.

One (1) VOC was detected in monitoring well MW-9 at a concentration at/or above its
respective 2L Standard and/or respective SW GWP Standard (Tetrachloroethene).
3.1.2 Metals
Barium was detected in each of the eleven monitoring wells, including the background
monitoring well MW-1. Barium was detected at a concentration of 752 micrograms per
liter (µg/L) in MW -4 and in MW-6A at a concentration of 805 µg/L , which is above its
2L Standard of 700 µg/L.

Cadmium was detected in monitoring wells MW-2, MW-6, and MW-7. Cadmium was
detected above its 2L Standard of 2 µg/L in monitoring well MW-7 at a concentration of
5.44 µg/L.

Chromium was detected in monitoring wells MW-1, MW-2, MW-4, MW-7, MW-9, and

Please note that the concentrations of metals in the monitoring wells fluctuate with time
and may be due to suspended solids rather than actual dissolved metals.

No other metals were detected in the monitoring wells.

Notes:
(1) Hydraulic Conductivity was calculated from slug tests performed after well construction.
(2) Effective porosity was estimated from soils collected within the saturated portion of screen interval during
well construction.
(3) Hydraulic gradient calculated by measuring linear feet between selected contour intervals.
(4) Seepage velocity v = (K*i)/ne

Notes:
(1) Recorded measurements are in percent methane.
(2) Methane monitoring wells 5 through 9 were installed during the 2008 assessment activities.
(3) Methane monitoring wells 1 and 3 were removed from the monitoring plan following the 2008 assessment
activities due to their close proximity to the edge of waste.
(4) Highlighted data are above 100 percent of the lower explosive limit.
(5) Lower explosive limit for methane is 5 percent.
(6) Upper explosive limit for methane is 15 percent.
(7) N/A = Not Available
