Volatile organic compounds (VOCs), including tetrachloroethylene (PCE), trichloroethylene (TCE), and other compounds were present in groundwater, and soil vapor in a relatively deep water table condition (70 feet). The site was redeveloped with multi-family homes. The local Department of Toxic substances required the installation of a sub-slab remediation system. The best solution for this problem was defined to be a soil vapor extraction system.
Mutch Associates was retained to simulate and optimize the number and locations of wells for the full-scale SVE system, based on a previous pilot SVE test conducted by the Engineering firm. The key goal of the project was to determine the optimal number and location of SVE wells to maintain a downward gradient, eliminating the VI pathway and therefore any risks to the homes.
