TOXIC ‘FOREVER CHEMICALS’ DETECTED IN DRINKING WATER SUPPLIES ACROSS CALIFORNIA

Drinking water sources for 74 community water systems serving 7.5 million Californians are contaminated with the highly toxic fluorinated chemicals called PFAS, according to an Environmental Working Group review of the latest state data.

Very low doses of PFAS chemicals in drinking water have been linked to an increased risk of cancer, reproductive and immune system harm, liver and thyroid disease, and other health problems. All of the detections in California water systems’ sources exceeded 1 part per trillion, or ppt, the safe level recommended by the best independent studies and endorsed by EWG.

More than 40 percent of the systems had at least one sample with a level of total PFAS over 70 ppt, the U.S. Environmental Protection Agency’s inadequate lifetime health advisory level for the two most notorious fluorinated chemicals, PFOA and PFOS. In addition to those two compounds, some California water systems detected up to six other PFAS chemicals.
