200 million Americans may be drinking contaminated water

Various studies conducted in the United States have revealed the presence of contaminants in drinking water, posing a significant public health risk. Here are some key findings:

PFAS Contamination ("Forever chemicals")

• Widespread exposure: A 2020 study by the Environmental Working Group estimated that over 200 million Americans could be consuming drinking water contaminated with perfluoroalkyl and polyfluoroalkyl substances (PFAS). (es.wired.com)

• Impact on vulnerable communities: 2023 research indicated that water systems in areas with a higher percentage of Hispanic and African American residents had higher PFAS levels, highlighting inequalities in exposure to these contaminants. (larepublica.es)

Health risks from chemicals in drinking water

• Increased cancer risk: A study by the Keck School of Medicine at the University of Southern California found a link between the presence of certain chemicals in drinking water and a higher incidence of various types of cancer. (eltiempo.com)

Regulatory actions and challenges

• Measures to eliminate contaminants: In response to these findings, U.S. authorities have implemented regulations to reduce and eliminate PFAS from drinking water, recognizing their persistence and harmful effects. (es.wired.com)
