Pre-Design Investigation SSS-3

Site-Wide Soils & Sediments
PDI SSS-3 Sub-slab Soil Characterization


Similar to PDI SSS-1, the lateral and vertical extent of contamination in soils beneath the former building slabs will be assessed to identify areas that need remediated based on possible leaks from utilities.

Composite subsurface soils will be collected via GeoProbe to depths of up to 26 feet and analyzed for site Constituents of Concern (COCs). Data collected during the PDI SSS-3 will be provided to EPA and incorporated into the 30% Design.
