New research from UC Berkeley reveals that public water wells in rural, predominantly Latinx communities may be disproportionately affected by PFAS (per and polyfluoroalkyl substances) contamination. 

These PFAS, or “forever chemicals,” are linked to various health risks and have been widely used in industries and consumer products for decades. The EPA recently set limits for PFAS in drinking water, and traditional water monitoring is missing the mark. Current methods fail to consider pesticides as a potential source of PFAS contamination. This study, a first of its kind, highlights a gap in our water safety net, particularly for rural communities. 

Key Takeaways for Water Treatment Professionals: 

  • PFAS from Pesticides: This research suggests a new pathway for PFAS to enter drinking water sources. Be aware of potential PFAS presence in areas with high agricultural activity. 
  • Environmental Justice Concerns: Rural, Latinx communities may be at greater risk due to reliance on small water systems and historical exposure to environmental hazards. Expanding PFAS monitoring to these areas is crucial. 
  • The Need for Proactive Measures: Water treatment professionals should consider including PFAS testing in their protocols, especially for clients in at-risk areas. Partnering with local organizations serving rural and minority communities can be a powerful step towards ensuring equitable access to safe drinking water. 
  • The Future of PFAS and Water Safety: The UC Berkeley researchers are continuing their work with a follow-up study that will directly test wells in vulnerable communities. This ongoing research will provide valuable data to guide future regulations and treatment strategies. 

By staying informed about emerging contaminants like PFAS and prioritizing environmental justice, water treatment professionals can play a key role in safeguarding public health.
