Office(s): Environmental Management, Savannah River Operations Office

An acidic plume emanating from the H-Area Seepage Basins has caused the mobilization of metals and radionuclides into the groundwater flowing toward Fourmile Branch. Subsurface barriers have been constructed up and down gradient of the seepage basins to mitigate the release of tritium and metals to Fourmile Branch. Thirty-one injection/monitoring wells will be installed to inject a base solution to raise pH of groundwater.
