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 Health
Q Concentration > Than Soil RSL - Industrial Health Note 1: If analytical method detection limit > soil RSL
L�Q Detection limit > Than Residential Soil RSL
Detection limit > Than Industrial Soil RSL
- Indicates support/rationale for sediment COPC potentially attributable to coal ash.
Ni -Indicates constituent is not a sediment COPC potentially attributable to coal ash.
S.U. = Standard Units
mg/kg = milligram per kilogram
< = 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
