… In 1994, Los Angeles County’s water quality watchdog made a troubling discovery: Beneath the Phillips 66 refinery’s Carson site, there was a lake — of oil. … For more than a century, after all, the refinery polluted the surrounding groundwater and air by producing toxic chemicals. … The regional watchdog, the Los Angeles Regional Water Quality Control Board, ordered Phillips 66 to clean up the lake by pumping out the toxic waste and treating contaminated water. Those remediation efforts continue to this day. … But there is still no estimated date, [Los Angeles Water Board spokesperson Ailene] Voisin said, for when the cleanup effort will be done.
