GROUNDWATER FACTS
The Santa Susana Field Lab has an aquifer (groundwater) directly below it. DTSC claims the SSFL aquifer doesn’t impact local groundwater but EPA has questioned that assertion.
The SSFL groundwater is regulated by the DTSC. The SSFL surface water and NPDES are regulated by the Los Angeles Regional Water Quality Control Board.
According to the Water Board, groundwater is difficult, costly, and extremely slow to remediate.
500,000 gallons of TCE contaminate the SSFL groundwater, in addition to perchlorate, radionuclides, and other contaminates of concern.
Boeing’s Groundwater Covenant will last “in perpetuity” and allows the highly polluted groundwater under the Santa Susana Field Laboratory to remain polluted for “an indeterminate amount of time.”
