The EPA recently finalized its $111-million plan for containing and remediating contaminated ground water beneath the western side of the Aerojet Superfund site outside of Folsom, Calif.
Nine water supply wells have been lost to ground water contamination emanating from the Aerojet Site, and an estimated 13 additional public water supply wells could be lost over the next 25 years if the contaminated ground water is not contained and remediated. The ground water is contaminated with several compounds, including very high levels of perchlorate, a suspected human carcinogen and known developmental toxin.
