Jose Suarez is a physician and epidemiologist at the Herbert Wertheim School of Public Health at UC San Diego who studies environmental health and the effects of chemicals on health. The wells on the southern end, not over the limit for PFAS, are now supplying the base with drinking water, Ramsey said.ĭr. When water from the northern wells tested beyond those new guidelines in February, the base shut down some wells - eight of them - and notified base personnel and military families. In October, California set new lower limits on PFAS in drinking water. ![]() Water is pumped from several wells concentrated in the north and south ends of the base.
