Prepared by: KDF/SRW Checked by: MMS
Notes:
Bold highlighted concentrations indicate highest exceedance of the category listed below:
- EPA Region 4 Sail Screening Levels
- EPA Region 4 Effects Value for Sediment
- MDL is greater than EPA Region 4 Soil Screening Levels
- MDL is greater than EPA Region 4 Effects Value
Dup = Duplicate
mg/kg = miligram per kilogram
NE = Not established
S.U. = Standard Units
= percent
j = indicates concentration reported below Practical Quantitation Limit (PQL), but above Method Detection Limit (MDL) and therefore concentration is estimated.
< = concentration not detected at or above the reporting limit.
