Document Description
Approval of a Removal Action Workplan by the Department of Toxic Substances Control pursuant to Health & Safety Code, chapter 6.8 as submitted on March 11, 2009 by DeNova Homes. The proposed removal action is Enhanced Bioremediation with Monitored Natural Attenuation for the groundwater at the Site. A former solvent washing operations impacted the Site's groundwater to approximately 500' laterally from the source area. Groundwater was encountered at approximately 50' below ground surface beneath the Site during the Site investigations. Based on the human health screening, the Site soil meets unrestricted land use standards. However, the risk calculations indicated consumption and exposures to groundwater would pose a significant threat to human health. Based on this evaluation, DTSC required remediation of the groundwater.
