RE: 14-Day Notification of Groundwater Protection Standard Exceedance(s)

Dear Ms. Drummond:

In accordance with 15A NCAC 1313.1633(c)(1), Western Carolina University (WCU) is submitting a 14-Day
Notification of Groundwater Protection Standard Exceedance(s) form following the identification of an
exceedance of the concentration of 1,4-dioxane at WCU's Closed Municipal Solid Waste Landfill (MSWLF).
Groundwater and surface water samples were collected at WCU's Closed MSWLF on February 25, 2019 and
submitted for analysis of Appendix I volatile organic compounds according to EPA Method 8260, Appendix I
metals according to EPA Methods 6020A and 7470A, and 1,4-dioxane according to EPA Method 8260 SIM
(selective ion monitoring). The compound 1,4-dioxane was detected in groundwater samples collected from two
monitoring wells (MW-3 and MW-4) at concentrations greater than the North Carolina Groundwater Standard of
3 micrograms per liter, as summarized in the table below. Concentrations of 1,4-dioxane were not detected
above the method detection limit in the groundwater samples collected from monitoring wells MW-1 and MW-2,
or in the surface water samples collected at locations SW-1 and SW-2. The analytical report was received on
March 11, 2019, and the results were verbally communicated to you on March 12, 2019. This is the first time that
1,4-dioxane has been analyzed and detected, so there is no historical data with which to compare the February
2019 results. Further monitoring/evaluation will be necessary to determine a potential cause and significance of
the exceedances. This data, tabulated below, will be included in the February 2019 Semi-annual Water Quality
and Landfill Gas Monitoring Report that will be submitted to NCDEQ.
