Under new water quality standards issued by the state, the Pico Rivera water supply is now considered tainted.
The city will soon be sending notices to all residents about high levels of perfluorooctanoic acid and perfluorooctanesulfonic acid, more commonly referred to as PFOA and PFOS.
Dubbed “forever chemicals,” the two are “readily absorbed, but not readily eliminated from the human body,” according to the state’s Water Resources Control Board. Long-term exposure can damage an individual’s immune system, thyroid and liver. It can also cause cancer and harm developing fetuses and infants alike.
