Document Description
The Remedial Action Plan addresses vadose zone soil impacted with volatile organic compounds (VOCs) above Site cleanup goals. The proposed remedial action for the soil consists of: 1) removing soil containing trichloroethylene (TCE) and cis-1, 2-dichloroethylene (cis-1, 2-DCE) above site cleanup goals; and 2) restricting the property use to commercial and/or industrial uses. Both TCE and cis-1, 2-DCE have also been detected in shallow groundwater at the Site. However, shallow groundwater will be addressed in a separate remedy selection document. The objective of the current remedy is to address surface exposures and soils as a source of groundwater contamination.
