RE: SUMMARY OF PIEZOMETER ABANDONMENTS, GROUNDWATER AND LANDFILL GAS MONITORING WELL INSTALLATIONS, MONITORING WELL DEVELOPMENT,
GROUNDWATER MONITORING WELL IMPROVEMENTS, AND AQUIFER TESTS GREAT OAK LANDFILL, PERMIT NO. 76-07
Dear Ms. Ritter:
On behalf of Waste Management of Carolinas, Inc. (Waste Management), Golder Associates NC, Inc.
(Golder) is submitting this letter report summarizing environmental services associated with the Great Oak Landfill in Randolph County, North Carolina. This report details piezometer abandonments,
groundwater and landfill (LFG) monitoring well installations, monitoring well development and aquifer tests, and well improvements conducted by Golder in April and May 2016.
ABANDONMENT OF PIEZOMETERS
Between April 18, 2016, and May 10, 2016, Golder geologists provided oversight for the decommissioning
of twenty piezometers in accordance with Title 15A of the North Carolina Administrative Code (NCAC) 2C .0113(b). The piezometers were decommissioned by South Atlantic Environmental Drilling and
Construction Company, Inc. (SAEDACCO) of Fort Mill, South Carolina, a North Carolina certified well drilling company. Six piezometer locations (PZ-24, PZ-44, PZ-50, PZ-61S, PZ-61D, and PZ-62) are
outside of the future waste units and were abandoned by grouting in place. Four piezometers (OW-8, PZ-27, PZ-28, and PZ-52), which were installed in saprolite or partially weathered rock (PWR), were
overdrilled to remove well construction materials and then grouted due to their locations in the future waste units. Ten piezometers (OW-1, OW-2S, OW-2D, OW-3, PZ-29, PZ-30, PZ-31, PZ-33, PZ-34, and
PZ-64), which were installed into bedrock, were abandoned by a combination of grouting the annular space in bedrock in place, and overdrilling the portion of the piezometers in saprolite and PWR to remove
well construction materials. The piezometer locations are shown on Drawing 1. Copies of the well abandonment records (Form GW-30 Rev. 5/06) for the decommissioned piezometers are included as
Attachment A. Details of each abandonment procedure are provided below.
Grouting in Place
For piezometers located outside of the proposed waste units, abandonments were performed by filling the
polyvinyl-chloride (PVC) well annulus with neat cement grout from bottom to ground surface via tremie pipe. Additionally, surface completions of each piezometer were removed. The following table
summarizes the piezometers and total depths that were abandoned in place.

Overdrilling
Piezometers located within proposed waste units that were completed above bedrock were overdrilled
with hollow stem augers (HSAs) of sufficient size to remove all well construction materials from the borehole before being back-filled with neat cement grout from the bottom of the borehole to the top of
proposed base grades via tremie pipe procedures. The remaining annulus was backfilled with cuttings. Surface completions of each piezometer were removed. The abandonments were performed with
Deidrich D-60 Turbo, track-mounted drilling rig with either 4.25-inch inner diameter (ID) HSAs or 6.25-inch ID HSAs. The following table summarizes the piezometers, total depths, and top of base grades for
piezometers installed above bedrock.

Grouting in Place and Overdrilling
For piezometers located within proposed waste units that were completed within bedrock, the portion below the top of bedrock was backfilled (via tremie pipe) with neat cement grout and allowed to cure for
24 hours. Once sounded and depth of grout confirmed to meet the specified depth, the remaining upper borehole was overdrilled with HSAs to remove well materials and grouted to the top of proposed base
grades via tremie pipe procedures. The remaining annulus was backfilled with cuttings. Surface completions of each piezometer were removed. The abandonments were performed with Deidrich D-60
Turbo, track-mounted drilling rig with either 4.25-inch inner diameter (ID) HSAs or 6.25-inch ID HSAs. The following table summarizes the piezometers, total depths, top of bedrock, and top of base grades for
piezometers installed into bedrock.

METHANE MONITORING WELL INSTALLATIONS
Between April 19 – 21, 2016, Golder geologists provided oversight for the installation of four methane monitoring wells (MMW-1, MMW-2, MMW-3, and MMW-4) in accordance with 15A NCAC Subchapter
13B .0544(d)(2) and in the Landfill Gas Monitoring Guidance (November 2010). The methane monitoring wells were installed by SAEDACCO using a Deidrich D-60 Turbo drilling rig utilizing 4.25-inch ID HSAs.
The borings were advanced to auger refusal, which was interpreted as the top of bedrock. Groundwater was not encountered in any of the borings.
The methane monitoring probes were constructed with 2-inch schedule 40 PVC screen and riser pipe. The 0.010-inch slotted screen was installed from the bottom of each probe to 5 ft bgs. Concrete aprons
and lockable aluminum protective casings were installed at each methane monitoring well location. Sampling ports were installed on the top of each riser pipe. The methane monitoring wells were surveyed
by Charles Morgan Surveying, PLLC of Asheboro, North Carolina in May 2016. A sealed survey summary table is provided as Attachment B.
A summary of methane monitoring well drilling and construction information is attached as Table 1. Boring and well construction logs for the methane monitoring probes and the Well Construction Records
(Form GW-1B Rev. 2/09) are included in Attachment C. The locations of the methane monitoring probes are shown on Drawing 1. Photographs of the completed methane monitoring wells are included as
Figure 1.
GROUNDWATER MONITORING WELLS INSTALLATIONS
Between April 18, 2016 and May 9, 2016, Golder geologists provided oversight for the installation of two
monitoring wells (MW-2 and MW-3) in accordance with 15A NCAC Subchapter 2C .0100 and in the Draft North Carolina Water Quality Monitoring Guidance Document for Solid Waste Facilities; Solid Waste
Section, Division of Solid Waste Management; Department of Environment, Health and Natural Resources (March 1995). The wells were drilled and installed by SAEDACCO using a Deidrich D-60
Turbo drilling rig with 4.25-inch ID HSAs and a 4-inch outer diameter (OD) downhole hammer. Split-spoon samples were collected on 5-foot centers for geologic description and SPT blow-counts.
The borings were advanced through saprolite and PWR utilizing HSAs to auger refusal. Groundwater was not encountered above bedrock. The borings were then advanced to fractured water bearing zones
utilizing a downhole hammer with an external air compressor.
Ms. Christine Ritter, Hydrogeologist June 15, 2016 NC DEQ – Division of Waste Management 4 1547090

The monitoring wells were constructed of 2-inch schedule 40 PVC riser pipe and 10 ft of 0.010-inch
slotted pre-packed screens. Concrete aprons, lockable aluminum protective casings, and bollards were installed at each well location. A summary of well construction information is provided as Table 2.
Photographs of the completed monitoring wells are provided on Figure 2. The groundwater monitoring wells were surveyed by Charles Morgan Surveying, PLLC of Asheboro, North Carolina in May 2016. A
sealed survey summary table is provided as Attachment B. Boring and well construction logs for the groundwater monitoring probes and the Well Construction Records (Form GW-1B Rev. 2/09) are included
in Attachment D.
IMPROVEMENTS TO EXISTING GROUNDWATER MONITORING WELLS
On May 9, 2016, a Golder geologist provided oversight of improvements to existing groundwater monitoring wells. The improvements were made by a drilling crew from SAEDACCO. Steel bollards were
placed around monitoring wells MW-4 (formerly PZ-60), MW-5 (formerly PZ-32), and MW-6 (formerly PZ-47). A concrete apron and aluminum protective casing was installed at MW-1 (formerly PZ-22). The
concrete apron of MW-6 was replaced because the original apron was cracked. Photographs of the monitoring wells are provided on Figure 2.
GROUNDWATER MONITORING WELL DEVELOPMENT
Golder personnel developed the two newly-installed monitoring wells (MW-2 and MW-3) on May 23 and 24, 2016 using a Waterra Hydrolift Pump. Water levels were measured during the development activities
with an electronic water level indicator, and water quality measurements (pH, temperature, specific conductance, and turbidity) were collected during development. Between approximately 45 and 146
gallons of water were pumped from the wells MW-2 and MW-3, respectively. Monitoring well development data sheets are included in Attachment E.
AQUIFER TESTS
Between May 23 and 26, 2016, aquifer testing (slug tests) was performed by a Golder geologist on the six facility groundwater monitoring wells (MW-1, MW-2, MW-3, MW-4, MW-5, and MW-6) to estimate the horizontal hydraulic conductivity at each well location. Falling- and rising-head tests were performed on
each well except MW-2; because the water level in MW-2 intersected the well screen, only a rising-head test was performed. Prior to performing the slug tests, the wells were opened to the atmosphere for several minutes allowing groundwater levels to equilibrate. Groundwater levels were then measured
using an electronic water level indicator referenced to a surveyed point on the top of the piezometer casing. An In-Situ Level Troll 700 pressure transducer was lowered inside the well casing and placed approximately 5 to 25 feet below the top of the water table. A PVC slug measuring 5 feet in length was
then used to displace water inside the well.
After the slug was placed in the well, the pressure transducer measured water levels at logarithmic time intervals inside the piezometer casing until the water inside the piezometer casing returned to its static
level. This portion of the aquifer test is referred to as the falling-head test. Falling-head tests were terminated after water levels had recovered to within at least 99% of their pre-test level. After the completion of the falling-head test, a rising-head test was performed. At this point, the slug was removed from the piezometer as the pressure transducer measured the water level at a logarithmic time interval
inside the piezometer casing until the water level returned to its static water level measured before the start of the test.
The results of rising- and falling-head tests provide a quantitative estimate of horizontal hydraulic
conductivity. The slug test data were analyzed using the Bouwer and Rice (1976) equation, which is
applicable to fully or partially penetrating wells in unconfined or confined aquifers. An aquifer thickness of 50 ft was assumed for the bedrock portion of the aquifer. The computer software program AQTESOLV,
produced by HydroSOLVE, Inc., was used to assist in the analysis and plotting of data. The individual data points and computer plots of time versus groundwater displacement are presented in Attachment F. A summary of the aquifer testing and the calculated geometric mean for hydraulic conductivity of the hydrogeologic unit are presented in Table 3.
