Prepared by: BER LAM Checked by: KLS
Notes:
Bold highlighted concentration indicates highest exceedance of the EPA Mid -Atlantic Risk Assessment regional screening levels for soil, June 2015, for the category listed below:
- Soil RSL - Industrial Health
- Soil RSL - Residential Health
- Protection of Groundwater
% = percent
S.U. = Standard unit
mg/kg = milligram per kilogram
NE = Not established
< = 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.
