The table provides laboratory data for target analytes reported above method detection limits. 2. All laboratory data is in milligrams per kilogram (mg/kg).3. "<" = None detected above method detection limit.4. NE = Not Established 5. J = Value between Method Detection Limit and Pratical Quantitative Limit6. PID = Photo-Ionization Detector 7. ppmv = parts per million vapor 8. b = Elevated reporting limit(s) due to matrix interference9. Target analyte concentrations were compared to the established Branch SRGs and EPA Soil-to-Groundwater RSLs, published 2-2013.10. No target analyte concentration exceeded established North Carolina Department of Environment and Natural Resources (NCDENR) Inactive Hazardous Sites Branch (IHS Branch) SRGs and EPA Soil-to-Groundwater RSLs, published 2-2013. 11. Methylene chloride was detected in the laboratory method blank at an estimated concentration of 0.0054 mg/kg, which suggests that the estimated analytical detection of 0.0067 mg/kg in Sample C-1 represents laboratory bias.
