People living in Hispanic and Black communities in the U.S. are disproportionately exposed to toxic “forever chemicals” pollution in drinking water systems, according to a new public study published in the journal Environmental Science & Technology on Monday. Why it matters: The study contributes to previous research showing that people of color and low-income communities are excessively affected by other forms of pollution, too, including fine air particulate, lead and other drinking water contaminants. Driving the news: In March, the Environmental Protection Agency (EPA) proposed drinking water regulations on six compounds of a family of over 12,000 types of chemicals collectively called per- and polyfluoroalkyl substances (PFAS).
