RE: Water Quality Monitoring Report 2016 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 August 3 -
4, 2016, 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 August 3 - 4,
2016; surface water monitoring points US-1 and DS-1 were also sampled on this date. 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 August 2016 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 VOCs (1,1-dichloroethane; 1,2-dichloroethane; 1,4-dichlorobenzene; benzene;
chloroethane; chloromethane; methylene chloride; tetrachloroethene; and toluene) were detected in
samples from one or more compliance monitoring wells above their respective SWSLs during the August
2016 sampling event. Of these VOCs, the following constituents were detected above their respective
NC 2L Standards: 1,1-dichloroethane (MW-2); 1,2-dichloroethane (MW-2); benzene (MW-2);
chloromethane (MW-2); and tetrachloroethene (MW-1). The August 2016 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 August 2016 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 2017. If you have any questions, please contact the undersigned at 336-852-4903.

Project Name: Rowan County Closed Landfill
Project Reference Number: 0626572016.101
Sampling Event Date: 08/03-04/16
Review Date: 09/06/16 Initials: TJM
Report #: CZ10887
Person(s) performing the review are to initial each item on this form as acknowledgement of data acceptance,
or as acknowledgement of a review issue. In the case of the latter, a brief explanation should follow the
applicable item.

Golder Associates Inc. has reviewed the laboratory certificates of analysis, chain-of-custody form, and laboratory
provided sample group quality assurance and quality control data for the above referenced sample group to identify
potential bias or inaccuracy, in general accordance with the following United States Environmental Protection
Agency documents:

 Region III Modifications to Functional Guidelines for Organic Data Review Multi-Media, Multi-
Concentration, September 1994;
 Region III Modifications to the Laboratory Data Validation Functional Guidelines for Evaluating Inorganic
Analyses, April 1993; and
 Laboratory Data Validation Functional Guidelines for Evaluating Inorganic Analyses, July 1998.

ANALYTE LIST(S)

 Method 8260 NC Appendix I + 8 RCRA Metals

1.0 CHAIN OF CUSTODY (COC) REVIEW

TM COC was properly signed by all parties.

TM Correct project name and number are on the form.

TM Sample receipt condition at laboratory was acceptable.

TM Each sample and blank submitted for analysis appears in the report.

Notes:
2.0 SAMPLE HOLDING TIMES

TM Holding times for extraction and/or analysis were met for each analytical
Method (see lab manual for holding times).

3.0 LABORATORY QUALITY CONTROL REVIEW

TM Laboratory analyzed at least one internal blank for each method, where applicable.

TM Laboratory blank is interference-free.

TM Surrogate recoveries are provided for each analytical method, where applicable.

TM Surrogate recoveries for each method are within the acceptable limits (i.e., at least
50% of the surrogates were within range).

TM MS/MSD/LCS data results are provided for each analytical method.

TM MS/MSD/LCS recoveries for each method are within the acceptable limits (i.e., at least 1 of
the 3 were within range).

Notes:

4.0 ANALYTE LISTS/METHODS

TM The proper number of constituents are present for each analyte list as identified above
(including detects where applicable).
TM Proper analytical methods were used for analysis.

Notes:

5.0 DATA REPORTING

TM All analytical reporting associated with the event was performed by the contracted lab.

TM 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.

TM 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.

TM The report provides the reporting limit for each constituent.

TM The results were reported at or below their proper reporting limits (e.g., MDLs, MRLs,
PQLs, etc.). 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.

TM No inorganic and organic constituents were reported above their respective NC 2L Drinking
Water Standards in wells, surface points, or field/equipment/trip blanks.
 MW-1
o Tetrachloroethene = 2.9 ug/L (NC 2L = 0.7 ug/L)
 MW-2
o 1,1-DCA = 7.2 ug/L (NC 2L = 6 ug/L)
o 1,2-DCA = 1.2 ug/L (NC 2L = 0.4 ug/L)
o Benzene = 5.6 ug/L (NC 2L = 1 ug/L)
o Chloromethane = 6.1 ug/L (NC 2L = 3 ug/L)

TM For sites with historical data, no inorganic and organic constituents were detected in a well
or surface water point at concentrations outside of their historical range (more than 5X
previous concentrations or first-time detections).

TM Other report issues/Communications with laboratory/etc.:

 The detection of toluene in sample MW-3S was confirmed by reanalysis on a secondary
instrument. Both results are included in the report.
