The majority of the restoration work is removal of soil. After the soil is removed, more tests will be performed to ensure it meets the most stringent standards set forth by the Environmental Protection Agency (EPA) for residential development.
A monitoring well is used to obtain water quality samples and measure groundwater levels.
Approximately 400 acres of the 2,200 acres on the property require remediation and clean-up. There has never been any industrial activity on the remainder of the site, most of which has remained virgin desert. The evaporation ponds are now inactive. The soil underlying the ponds will be excavated and transported to a lined and monitored Corrective Action Management Unit(CAMU), off site. No excavated soils will be disposed of on-site.
The site's soil will be analyzed before and after the remediation. Each home site will be retested again before any residential construction begins.
EPA is an acronym for Environmental Protection Agency
