RE: 14-DAY NOTIFICATION AND ALTERNATE SOURCE
CLOSED HENDERSON COUNTY LANDFILL, PERMIT NO. 45-01
HENDERSON COUNTY, NORTH CAROLINA
Dear Jackie:
On behalf of Henderson County, Golder Associates NC, Inc. (Golder) is submitting this 14-Day Notification as required by North Carolina Solid Waste Management Regulation (NCSWMR) 15A North Carolina
Administrative Code (NCAC) 13B .1633(c)(1). The 14-Day Notification of Groundwater Protection Standard Exceedance(s) form is included as Attachment 1.
1.0 14-DAY NOTIFICATION [15A NCAC 13B .1633(C)(1)]
Table 1 (shown below) summarizes the NC Appendix I constituents that were detected at concentrations
above their respective solid waste section limits (SWSLs) and NC 2L Groundwater Standards or Solid Waste Section groundwater protection standards (GPSs) during the second Semi-annual Water Quality
Monitoring Event conducted at the closed municipal solid waste (MSW) landfill on September 20 - 22, 2016. Laboratory certificates of analysis are included as Attachment 2. It is noted that the closed MSW landfill is
in corrective action for volatile organic compounds (VOCs); therefore no notifications for groundwater standard exceedances for VOCs are required for this facility.

2.0 ALTERNATE SOURCE DEMONSTRATION [15A NCAC 13B .1633(C)(3)]
As allowed under 15A NCAC 13B .1633(C)(3), we have prepared an alternate source demonstration (ASD)
in reference to the concentrations of arsenic and barium in the sample from downgradient monitoring well MW-6, which were above their respective NC 2L Standard and SWSLs during the September 2016
compliance monitoring event.
The Summary of Statistical Analysis (Attachment 3) summarizes the statistical methods and results used
to determine an appropriate background concentrations for arsenic and barium at MW-6. The statistical analyses were completed using WQStat software in accordance with 40 CFR 258 and 15A NCAC 13B

5.0 DATA REPORTING
DR All analytical reporting associated with the event was performed by the contracted lab.
DR 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.

 Field Blank
o Copper @ 3.37 ug/L (J)
o The following copper detections have been blank qualified: MW-5, MW-8, AMW-1S, AMW-1D,
AMW-2S, AMW-2D, BR-1, and BR-3
DR 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. DR The report provides the reporting limit for each constituent.
DR 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.
DR No organic constituents were reported above their respective SWSLs, and no inorganic 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.
