A new study from the Silent Spring Institute reveals that nearly one-third of Americans have been exposed to unregulated contaminants in their drinking water. The research found that 27% of public water systems serving over 97 million people had detectable levels of at least one unregulated chemical.
The study highlights a significant disparity in exposure to these pollutants, with Hispanic and Black communities facing higher risks due to geographical proximity to pollution sources. Researchers believe systemic issues like racism and historical redlining contribute to this unequal distribution of pollution.
Among the contaminants found were PFAS chemicals, which are more widespread than previously thought. The EPA has set new drinking water standards for six PFAS chemicals, but the study emphasizes a need for broader regulation and action to address environmental injustices.
The researchers hope that making their inventory of unregulated contaminants publicly available will aid policymakers in creating realistic plans for preventing and mitigating water contamination. This data is crucial for ensuring safe drinking water for all Americans, particularly those most at risk.
