An increase in the cancer rate of up to 33% is suggested by research conducted by the University of Southern California’s (USC) Keck School of Medicine from exposure to “ubiquitous chemicals” detected in tap water.

Polyfluoroalkyl substances, (PFAS), now known as “ubiquitous chemicals,” are found in nearly half – 45% – of drinking water supplies in the United States and are linked, according to researchers, to an increase in the incidence of certain digestive, endocrine, respiratory, oral and throat cancers.
