A former foundry operated at this commercial building and utilized fuel oil that leaked into soil next to the building.  ERAS determined groundwater was not impacted (defined extent, LTCP #3), and removed oil-contaminated soil (removal of secondary source, LTCP #2).

 As a result of the presence of methane from degradation of oily contamination, ERAS installed a passive soil vapor mitigation system (VMS) to stop vapors from migrating into the building.  The Alameda County Department of Environmental Health (ACDEH) granted closure under the LTCP with the recording of a deed restriction that included an SMP.
