[phone] RE: Water Quality Monitoring Report 2017 Annual Sampling Event Rowan County Closed Sanitary Landfill, Permit No. 80-01 Rowan County, North Carolina
Dear Jackie:
On behalf of Rowan County Environmental Services (Rowan County), Golder Associates NC, Inc. (Golder) is submitting this Water Quality Monitoring Report, which documents the results of the July 24 -
25, 2017, annual compliance monitoring event at the above-referenced facility. A site location map is included as Figure 1.
Monitoring wells MW-1, MW-2, MW-3S, MW-3D, and MW-4 were purged and sampled on July 24 - 25,
2017; surface water monitoring points US-1 and DS-1 were also sampled on these dates. Figure 2 shows the approximate locations of these monitoring points. The field sampling logs for this event are included
in this report. The samples were sent to Environmental Conservation Laboratories, Inc. in Cary, North Carolina (NC) and were analyzed for the NC Appendix I list of volatile organic compounds (VOCs) and
eight Resource Conservation and Recovery Act (RCRA) metals.
As presented on Tables 1, one RCRA metal (barium) was detected above the Solid Waste Section Limit (SWSL) in samples from one or more downgradient monitoring wells during the July 2017 annual water
quality monitoring event. The barium concentrations were below the North Carolina (NC) Groundwater Quality (2L) Standard and generally consistent with historical results.
Nine NC Appendix I volatile organic constituents (VOCs) were detected in samples from one or more
compliance monitoring wells above their respective SWSLs during the July 2017 sampling event: benzene; chloroethane; 1,4-dichlorobenzene; 1,1-dichloroethane; 1,2-dichloroethane; 1chloromethane;
tetrachloroethene; toluene; and vinyl chloride. Of these VOCs, the following constituents were detected above their respective NC 2L Standards: benzene (MW-2); 1,1-dichloroethane (MW-2); 1,2-
dichloroethane (MW-2); chloromethane (MW-2); tetrachloroethene (MW-1); and vinyl chloride (MW-2). The July 2017 results are generally consistent with historical data.
No inorganic or organic constituents were detected in samples from the surface water monitoring points
above the applicable surface water standards or SWSLs during this event. In general, the detected constituents and concentrations from the July 2017 annual event are consistent with historical data.
Based on these results, Rowan County Environmental Services will continue monitoring the annual water
quality at this facility for NC Appendix I VOCs and RCRA metals. The next event is tentatively scheduled for July 2018. If you have any questions, please contact the undersigned at 336-852-4903.

3.0 LABORATORY QUALITY CONTROL REVIEW
WB Laboratory analyzed at least one internal blank for each method, where applicable.
WB Laboratory blank is interference-free.
WB Surrogate recoveries are provided for each analytical method, where applicable.

WB Surrogate recoveries for each method are within the acceptable limits (i.e., at least 50% of the surrogates were within range).
WB MS/MSD/LCS data results are provided for each analytical method.
WB MS/MSD/LCS recoveries for each method are within the acceptable limits (i.e., at
least 1 of the 3 were within range).

4.0 ANALYTE LISTS/METHODS

WB The proper number of constituents are present for each analyte list as identified above
(including detects where applicable).
WB Proper EPA SM 2540C-1997 analytical methods were used for analysis.

5.0 DATA REPORTING

WB All analytical reporting associated with the event was performed by the contracted
lab.
WB Trip, field and/or equipment, and laboratory blank results have all been reported. All

detects for blanks are listed below by constituent. All laboratory method blanks, if any, have been ‘flagged’ with a ‘B’ where detected in other samples as appropriate and a
laboratory narrative was provided. If the sample was flagged by the laboratory and is
not within 5X of the concentration in the blank (or 10X for commonly detected laboratory contaminants-acetone, methylene chloride and phthalates), list below with explanation if flags should be removed. If flags need to be added for samples, also
list below.

 Trip Blank:
• Acetone @ 12 ug/L (J), B flag should be added to:
 MW-2 @ 22 ug/L (J)

WB It is clear from the laboratory report that samples have or have not been diluted during analysis, and if the samples have been diluted, the result is reported as a multiple of
the dilution (e.g., a sample diluted 10x resulting in an analytical detection of 1.0 should
be reported as 10). Those that have been diluted are listed below with the dilution factor.
WB The report provides the reporting limit for each constituent.
WB The results were reported at or below their proper reporting limits (i.e., MDLs with
SWSLs reported). Those that are not reported correctly are listed below (by
constituent) with the proper reporting limit listed beside them. State if the reporting limit error is due to dilutions.
WB No organic or organic constituents were reported above their respective NC 2L
Drinking Water Standards/GWPS in wells, or field/equipment/trip blanks, or above applicable surface water standards in surface water points.

 1,1-Dichloroethane (NC 2L = 6 ug/L)
• MW-2 @ 7.8 ug/L
 1,2-Dichloroethane (NC 2L = 0.4 ug/L)
• MW-2 @ 1.5 ug/L
 Benzene (NC 2L = 1 ug/L)
• MW-2 @ 8.6 ug/L
 Chloromethane (NC 2L = 3 ug/L)
• MW-2 @ 5.0 ug/L
 Tetrachloroethene (NC 2L = 0.7 ug/L)
• MW-1 @ 2.3 ug/L
 Vinyl Chloride (NC 2L = 0.03 ug/L)]
• MW-2 @ 1.1 ug/L
WB No inorganic or organic constituents were detected in a well or surface water point at
quantified concentrations outside of their historical range (more than 5X previous
concentrations or first-time detections).
 MW-2
• Bromoform @ 0.69 ug/L (J), first time detection
