Notes
Bold color highlighted concentrations indicate highest exceedance of the EPA Mid -Atlantic Risk Assessment regional screening levels (RSLs) for soil, June 26, 2015, for the category listed below:
©- Concentration > Than Soil RSL - Residential-
®- Concentration > Than Soil RSL - Industrial -Use Scenario Note 1: If analytical method detection limit > soil RSL
- Detection limit > Than Residential Soil RSL
- Detection limit > Than Industrial Soil RSL
- Indicates support/rationale for sediment COPC potentially attributable to coal ash.
- Indicates constituent is not a sediment COPC potentially attributable to coal ash.
S.U. = Standard Units
mg/kg = milligram per kilogram
% = percent
DUP = Duplicate
< = concentration not detected at or above the reporting limit.
j = indicates concentration reported below Practical Quantitation Limit (PQL), but above Method Detection Limit (MDL) and therefore concentration is estimated
