A recent report from the U.S. Geological Survey (USGS) reveals concerning findings about per and poly-fluoroalkyl substances (PFAS), commonly known as “forever chemicals,” in American tap water.
Extent of Contamination
According to the USGS study, conducted between 2016 and 2021 across 716 locations in the U.S., PFAS were detected in at least 45% of American tap water samples. This widespread presence indicates a significant public health concern, as PFAS are known to persist in the environment and the human body for long periods without breaking down.
Health Implications
PFAS have been linked to serious health problems including cancer, thyroid disease, liver disease, kidney disease, infertility, and autoimmune disorders. The National Institutes of Health (NIH) categorizes PFAS as “forever chemicals” due to their persistent nature and associated health risks.
Geographic Distribution
The study highlights a higher likelihood (approximately 75%) of finding PFAS in tap water samples from rural areas compared to urban areas (25%). Regions such as the Great Plains, Great Lakes, Eastern Seaboard, and Central/Southern California are noted as particularly high-exposure areas based on the study’s findings.
Study Details and Recommendations
USGS research hydrologist Kelly Smalling, the report’s lead author, emphasizes the comprehensive nature of the study, which included testing water directly from kitchen sinks across the nation. The study found comparable PFAS concentrations in tap water from both public water systems and private wells.
Public Awareness and Action
The findings underscore the importance of public awareness and action in addressing PFAS contamination. Homeowners relying on private wells are advised to test and potentially treat their water supplies, while the Environmental Protection Agency (EPA) oversees testing and regulation of public water supplies.
Conclusion
In light of these findings, it’s crucial for individuals to stay informed about the quality of their drinking water. Concerned citizens can use this research to assess their own risks and seek guidance from local health authorities on testing and treatment options for PFAS contamination in their area.
