1.0 INTRODUCTION
1.1 Site Information
The Wilkes County Roaring River Landfill is owned and operated by Wilkes County under Permit No. 97-04. The landfill property is located near the town of Roaring River, North Carolina. The site is located on a group of knolls rising over 150 feet above the floodplain of the Yadkin River. The approximate property boundary and disposal area are indicated on an
enlarged portion of the USGS 7 ½ minute topographic map for Ronda, North Carolina
(Figure 1).
Wilkes County submitted a Design Hydrogeologic Report in 1991 to North Carolina Department of Environment and Natural Resources (NCDENR) and the facility began accepting waste in the Subtitle D lined Phase 1 in 1993. This cell, which occupies approximately 11.7 acres of the
facility, reached final capacity in 1999. The Phase 2 disposal area reached final capacity in July
2006. A Design Hydrogeologic Report for the 6.6 acre Phase 3 was completed in May 2004 and construction was completed January 2006. Phase 4 of the waste disposal unit will be a vertical expansion of the Phase 3 area, as agreed upon in a December 10, 2002, site meeting with Sherri Coghill of the NCDENR. A leachate lagoon is located southwest of the approximately 12-acre
lined area.
1.2 Site Geology
The site is located at the boundary of the Inner Piedmont Belt and Blue Ridge Belt in the Brevard Fault Zone. In the vicinity of the site, the Brevard Fault Zone is a five-mile wide, east-northeast trending fault zone with a complex structural and metamorphic history. Finely interlayered
gneiss and schist within the zone are amphibolite facies, with peak metamorphism as high as the
kyanite zone for pelitic assemblages. Typically, the more highly-strained and faulted parts of the zone have experienced retrograde metamorphism to greenschist facies. Rocks in the Brevard Zone have undergone various degrees of both ductile and brittle deformation. Espenshade and others mapped four continuous faults that either bound the zone or separate rock units
consistently over long distances. These faults contain both mylonitic and cataclastic rock, and
exhibit the greatest degree of retrograde metamorphism. Two of these faults cross on or near the site. Bedrock at the site and in the Brevard Zone generally is more highly fractured than rock typical of most Piedmont and Mountain sites.
1.3 Regulatory Status
Wilkes County completes groundwater monitoring at the Roaring River Landfill in accordance
with the North Carolina Solid Waste Management Regulations (NCSWMR) § 1633 (Detection Monitoring Program). The facility currently monitors groundwater for the 40 CFR Part 258 Appendix I incorporated by reference into the NCSWMP (NC Appendix I) constituents and leachate for parameters listed under Section 2.2 Leachate Monitoring Program. Statistical
analyses of the laboratory data have been prepared in accordance with the required compliance
demonstration Rule .1632 (g) and (h) of the NCSWMR.

2.0 FACILITY MONITORING PROGRAM
2.1 Groundwater Monitoring Program
Eleven active groundwater monitoring wells comprise the monitoring network at the Roaring River Landfill. The current compliance network consists of the following monitoring wells: MW-13 (facility background well), MW-5, MW-6, MW-7, MW-8, MW-9, MW-10, MW-12S, MW-12D, MW-17, and MW-18. The approximate locations for the monitoring wells can be
found in Drawing 1.

MW-17 8/26/03 Compliance Detection 24.63 Saprolite
MW-18 8/26/03 Compliance Detection 46.85 Saprolite
Monitoring well MW-13 is the current background monitoring well for the facility. Monitoring wells MW-5, -6, -7, -8, -9, and -10 are monitored to detect potential releases from Phase 1. Monitoring wells MW-12S and -12D were installed in March 2000 to be incorporated into the monitoring network to effectively monitor Cell 2. Wells MW-17 and MW-18 were installed during the Design Hydrogeologic Investigation for Phases 3 and 4 and were incorporated into the
facility network after the June 2006 approval of the revised Groundwater Monitoring Plan.
2.2 Leachate Monitoring Program
One leachate monitoring point (Leachate) collected from the leachate collection pond is sampled on a semiannual basis at the Roaring River Landfill. The approximate location for monitoring point Leachate is included in Drawing 1 and the laboratory results are included in Appendix 1.
The following constituents are required for laboratory leachate analysis:
• North Carolina Appendix I Metals (plus Manganese, Molybdenum, and Mercury)
• North Carolina Appendix I 8260 Volatiles
• Biochemical Oxygen Demand
• Oil & Grease
• Cyanide
• Total Suspended Solids
•

3.0 SECOND SEMIANNUAL SAMPLING EVENT OF 2017
3.1 Field Work
On October 18-19, 2017 personnel from Joyce Engineering (JOYCE) visited Roaring River landfill to conduct the Second Semiannual Sampling Event of 2017. The sampling event included obtaining water levels to the nearest 0.01 foot, purge and collect groundwater samples from eleven monitoring wells (MW-5, MW-6, MW-7, MW-8, MW-9, MW-10, MW-12S, MW-
12D, MW-13, MW-17 and MW-18) and one leachate monitoring point (Leachate). Monitoring
wells MW-5, MW-6, MW-7, MW-10, and MW-12S were either dry, the bailer was unable to reach the water column, or there was not enough groundwater to purge and sample. The approximate locations for the monitoring wells and surface water monitoring points are shown in Drawing 1.
Monitoring wells were purged and sampled using disposable bailers. Measurements of
temperature, pH, specific conductivity, and turbidity were recorded prior to purging, after each purge volume, and after sampling. Copies of the field data logs are presented in Appendix 1 and the field parameters are provided in Table 3. Prior to sampling, laboratory-supplied containers were prepared with the following information:
• Monitoring well number (completed by laboratory/field personnel),
• Date and time of sample collection (completed by laboratory/field personnel),
• Initials of sampling personnel (completed by laboratory/field personnel),
• Project name and number (completed by the laboratory/field personnel),
• Chemical preservative (completed by the laboratory/field personnel); and
• Requested chemical analysis (completed by the laboratory/field personnel).
Groundwater samples from each monitoring well were collected directly from the bailers in the provided laboratory containers within 24 hours of the final purge volume. Immediately after collection, the samples were placed in a laboratory provided cooler and chilled on ice.
Leachate samples were collected from a leachate lagoon. Prepared sampling containers were filled, placed in a cooler, and chilled on ice. At the time of sampling, leachate was measured for
temperature, pH, specific conductivity, and turbidity. Field Logs are included in Appendix 1.
3.2 Laboratory Analysis and JOYCE Quality Control
The October 2017 groundwater and leachate samples were submitted to Pace Analytical Laboratories, Inc. of Huntersville, North Carolina under chain-of-custody control for analysis. JOYCE requested a Level II data report for the final laboratory reports. The samples were
received by the laboratory on October 20, 2017, in good condition, properly preserved in the desired temperature and within the hold times for each analytical method.
In addition to samples collected for compliance monitoring at the Roaring River Landfill, a Field Blank was collected by JOYCE personnel as part of the October 2017 sampling event. Also, a Trip Blank that was prepared by the laboratory accompanied the volatile sampling containers to
Second Semiannual Water Quality Monitoring Report of 2017 Joyce Engineering Wilkes County Roaring River Landfill, Permit No. 97-04February 2018 4
and from the laboratory. The Field Blank was analyzed for the NC Appendix I listed
constituents while the Trip Blank was analyzed for NC Appendix I volatile organics only.
Upon receipt of the laboratory data package, the data was reviewed by JOYCE personnel for the following:
• General typographical errors,
• Correct analyses performed and within method specified hold times,
• Biased data results based on Matrix Spike, Matrix Spike Duplicate, and Laboratory Control Samples,
• Blank qualified data (B-flags),
• Detections above the NC 2L Groundwater Standards or Groundwater Water Protection Standards (GWPS); and
• Detections that are above historical levels.
4.0 HYDROGEOLOGICAL CONDITIONS
Surface water at the site flows to the south-southwest in three site drainage features to the Yadkin River, which borders the southeastern facility boundary. Regional groundwater flow in the vicinity of the facility is also generally to the south-southwest and discharges to the Yadkin River. Groundwater beneath the site flows in surficial aquifers, compose of porous medium and
a fractured bedrock. Most of the groundwater flowing in this surficial discharges either to the alluvial sediment of the Yadkin River floodplain, or to the lowermost reaches of the three site surface drainage features before reaching the river.
Depth to groundwater was measured in the compliance monitoring wells at the site prior to purging. The groundwater elevations were calculated by subtracting the depth to groundwater
from the surveyed measuring point elevation (top of casing) for each monitoring well. The historical groundwater elevations are summarized in Appendix 2. The groundwater elevation contours shown on Drawing 1 are based on data from the October 2017 sampling event.
The estimated horizontal groundwater gradients from October 2017 groundwater levels ranges from 0.0411 to 0.093 ft/ft are presented in Table 4. The average horizontal gradient is
approximately 0.062 ft/ft.
Hydraulic conductivities (K) of 5.5E-01 for the site was estimated were based on slug test values from the Design Hydrogeologic Report submitted in October 2004. An effective porosity of 16% was used to estimate average linear groundwater flow velocities. Linear groundwater flow velocities for wells screened in saprolite were computed using the following modified Darcy
equation:
V = Ki/ne
where V = average linear velocity (feet per year), K = hydraulic conductivity (ft/day), i = horizontal hydraulic gradient, and ne = effective porosity.
Second Semiannual Water Quality Monitoring Report of 2017 Joyce Engineering Wilkes County Roaring River Landfill, Permit No. 97-04February 2018 5
Based on calculations from the most recent sampling event, the average estimated linear
groundwater flow velocity for the site is approximately 78.41 ft/year (Table 4). This falls within
the range of historical estimates for groundwater flow velocities at this site. The linear velocity equation and resulting rates are based on simplified assumptions of a homogeneous and isotropic aquifer. This equation can over-estimate velocities when applied to heterogeneous and/or anisotropic conditions such as are believed to exist at this site. The regolith and fractured
bedrock common in Piedmont terrain are characteristically heterogeneous. Site boring logs
record that regolith sampled at the site commonly exhibits relict foliation. These structures can result in locally anisotropic groundwater flow directions.
5.0 DATA ANALYSIS AND STATISTICAL RESULTS
Results from the October 2017 sampling event were received on October 20, 2017 from Pace
Analytical Laboratories, Inc. and are found in Appendix 1. Due to an instrument error, results
showed detections arsenic in monitoring well MW-12. The samples were reanalyzed and showed no detections of arsenic in MW-12. The revised version of the analytical results were received on January 04, 2018.
5.1 Analytical Results for Groundwater and Comparisons to Standards
Zinc was detected at quantified concentrations in MW-9, MW-12D, MW-17, and MW-18 during
the monitoring event; however, they did not exceed the NC2L standard or GWPS for each constituent. Cadmium was detected at quantified concentration in MW-17 and exceeded the NC2L standard. Chloromethane was detected with a “B” in monitoring wells MW-9, MW-17 and MW-18 due to blank contamination (Appendix 2). The analytical results are summarized in
Appendix 1 and the field parameters can be found in Table 3, respectively.
Concentrations of constituents reported for leachate samples collected during the October 2017 monitoring event from the leachate lagoon are consistent with historical data. The analytical results are summarized in the Appendix 1 and the leachate field parameters can be found in Table 3.
5.2 Statistical Methods and Results
When needed, the background data for inorganic constituents were evaluated using the Shapiro-Wilk Test, Parametric Prediction Limits, Parametric Tolerance Intervals, Aitchison’s Adjustment, Non-Parametric Prediction Limits, and Poisson Prediction Limits as appropriate. Background data, tests for normality, outliers, Aitchison’s adjustment, tolerance interval, or
prediction limits are used, as appropriate, based on the background data. The statistical test by
which downgradient data are compared to facility background data is based upon the nature of the data and the number of data values that are less than the laboratory limit of detection. All statistical tests are evaluated at the 0.05 level of significance, 95% confidence level, and are conducted as one-tailed tests.
Cadmium was detected at quantified concentrations above their respective NC 2L Standards in
MW-17 during the October 2017 sampling event. Therefore, in accordance with the procedures
Second Semiannual Water Quality Monitoring Report of 2017 Joyce Engineering Wilkes County Roaring River Landfill, Permit No. 97-04February 2018 6
outlined in 15A NCAC 13B.1632 (g) and (h), analysis was required. Statistical analysis
indicated a value of 18.0 µg/l. A summary of the October 2017 statistical background
calculations are provided in Appendix 7.
6.0 CONCLUSION
Based on analytical results from the monitoring event, the Roaring River Landfill will remain in the Detection Monitoring program as outlined in Title 15A NCAC 13B .1633. The next
semiannual sampling event is tentatively scheduled for April 2018.

NOTES:
All concentrations are reported in micrograms per liter (ug/L).
Values in parentheses represent duplicate sample results.
MW = Groundwater monitoring well.
DL = Laboratory detection limit.
QL = Laboratory reporting limit (NC SWSL {or lower} June 2007 - present).
ND = Not detected above laboratory reporting limit.
--- = Not sampled and/or not reported
January 2004 results represent a resampling event. Sample was analyzed by ENCO Laboratories.
May 2004 results for MW-8 were analyzed by ENCO Laboratories. Well was damaged during regular sampling event.
NC 2L = North Carolina 2 L Standard.
GWPS = Groundwater Protection Standards.
Detections above the NC 2L/GWPS are highlighted.
MW-8 was damaged prior to the April 04 sampling event and no sample could be obtained; therefore, a sample was obtained during May 04 after well repairs were made.
MW-2 was replaced with MW-2R prior to the April 2002 sampling event
MW-2R was replaced with MW-13 prior to the November 2010 sampling event.
NI= Not installed
B = Reported detect considered to represent blank contamination.

Notes:
MW = groundwater monitoring well
--- = not measured and/or not reported
Jan-04 data are from a resampling event.
MW-8 was damaged prior to the April 04 sampling event and no sample could be obtained; therefore, a sample was obtained during May 04 after well repairs were made.
