Project Highlight: Design and Implementation of PFAS Injection Pilot Test

At a former metal plating facility, soil and groundwater was contaminated with production waste including hexavalent chrome and PFAS (PFOS, PFHxS). Cascade was brought in to perform a pilot test to demonstrate the feasibility of full scale remediation of groundwater. The pilot test was conducted in the center of the plume consisting of 10 direct push injection locations in the vicinity of 2 newly installed monitoring wells.

Cascade utilized our ColloidalChem + ISCR^TM technology for hexavalent chrome reduction and PFAS sequestration.
During monitoring events post injection, MCIs were met for hexavalent chrome and PFOS/PFHxS.
