Editorial: Get the ‘forever chemicals’ out of our drinking water

A recent study by the U.S. Geological Survey found that nearly half of the drinking water in the United States is contaminated with “forever chemicals,” the per- and polyfluoroakyl substances known as PFAS that can cause cancer and other health complications. And Southern California is among a handful of regions nationwide with a higher probability of tap water contaminated with PFAS.

These findings are worrisome, particularly for communities that are already suffering from other sources of pollution. In Los Angeles County, water agencies in cities such as Commerce, Montebello, Monterey Park, Vernon, Downey were found to have PFAS higher than the recommended levels as early as 2019.

Los Angeles County supervisors this week launched an effort to assess the full extent of PFAS contamination in drinking water supplies. It’s a good first step, but state and local authorities must do more to ensure drinking water is free of these chemicals, which are found in many household products, including cookware and cosmetics.

PFAS were first classified as an “emerging contaminant” by the U.S. Environmental Protection Agency in 2016. But little is known about any disparities of PFAS contamination in different ethnic communities or the specific harms this pollution may be inflicting on these communities.

Last month, researchers at the University of Southern California began a new study on the health effects of PFAS contamination in drinking water in Los Angeles County, focusing on the predominantly Latino communities in the east and southeast that are overburdened with environmental pollution. The multidisciplinary study, which involves researchers from USC’s medical and engineering schools, aims to develop prevention strategies and large-scale, sustainable remediation solutions that can be implemented in a cost-effective manner.

Lead researcher Lida Chatzi, director of USC’s Center for Translational Research on Environmental Health, said previous research has linked exposure to PFAS to nonalcoholic fatty liver disease and metabolic disorders. Other research she has conducted found that a mixture of PFAS can cause the disruption of critical biological processes in youth, increasing the risk of cardiovascular and metabolic diseases, developmental disorders and many types of cancer. In the latest study, scientists will study the effect of newer PFAS that have been created to […]
