Document Description
The Department of Toxic Substances Control (DTSC) is proposing Corrective Measures for soil and groundwater at the Gardena Sumps (Site). Corrective measures would involve excavating the Haack Rework Area and a portion of sludge overflow along the eastern perimeter of the Cooper Sumps and consolidating the materials above the Cooper North and South Sumps. A cap consisting of a stabilization layer, foundation layer, low-hydraulic conductivity layer, and erosion resistance layer would be constructed above the sumps. A vapor control and monitoring system would be installed beneath the cap and around the sumps, and existing groundwater monitoring occurring at the Site would continue.
