BAM and ABC+ Treating PCE Plume
The subsurface beneath a currently busy, multi-business structure is delineated as the source area for impacted groundwater. The soil matrix is predominantly silt. Remedial DPT injections targeted migrating plumes emerging from the source area. ORIN first conducted a pilot test around MW3 and MW-4, proving the effectiveness of the combined treatment chemistries. BAM was allocated into two thirds of the DPT injection locations in a grid like pattern. The remaining one third injection locations received ABC+. Non-detectable levels of PCE were measured in MW-4 with no rebounding. ORIN later proceeded with full scale remedial activities around several additional target wells of the plume areas and a polish around MW-3. These results are amalgamated below.
