SCV Water’s November 2019 quarterly well sampling of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) found one well in excess of the state’s nonregulatory notification levels for PFAS chemicals, the agency reported Wednesday.
This well is in addition to 28 wells identified during the previous rounds of sampling in May and August 2019. Per- and polyfluoroalkyl substances (PFAS) are a group of manmade chemicals that are prevalent in the environment and were commonly used in industrial and consumer products to repel grease, moisture, oil, water and stains.
These chemicals enter the environment through treated wastewater discharge, landfills and areas where the substances were used outdoors. Exposure to these chemicals may cause adverse health effects.
“Like many communities across the nation, small amounts of PFAS have shown up in some of our water supply. We have a treatment facility that will be online by summer, and we will continue to seek the best strategies to attack this issue,” said SCV Water General Manager Matt Stone.
“Our customers are our top priority, and we are committed to rigorously testing our water thousands of times per year to ensure it meets or surpasses all water-quality standards and is safe to drink for our customers,” Stone said.
In August 2019, the State Water Resources Control Board – Division of Drinking Water (DDW) updated state guidelines and lowered the notification levels by more than half, to 6.5 parts per trillion (ppt) for PFOS and 5.1 ppt for PFOA, making them some of the most stringent guidelines in the nation.
