EPA to study carcinogens in tap water — science newsNovember 16, 1974
In some areas, there is evidence that clean drinking water may contain carcinogenic compounds. Many of the compounds detected contain chlorine, and some scientists believe that chlorine added to purify water can combine with organic materials not removed during filtration to form hazardous substances. I think there is a possibility that

These findings hastened the passage of the Safe Drinking Water Act, which gives the U.S. Environmental Protection Agency authority to set minimum standards for contaminant levels.SN: March 29, 1975, p. 208). Chlorine is still used to kill waterborne pathogens, but the EPA has limited levels of its byproducts, trihalomethanes and chlorine. haloacetic acid. Long-term exposure to these chemicals is associated with an increased risk of cancer. Currently, government agencies are targeting lead and PFAS, forever chemicals that have been linked to a myriad of health problems (SN: November 29, 2022). The EPA recently set standards for PFAS, requiring most lead pipe service lines to be replaced within 10 years.
