New EPA List Could Curb Water Contaminants

The Environmental Protection Agency (EPA) announced a proposal on Thursday to include microplastics and pharmaceuticals on the Contaminant Candidate List, a significant move that could result in new federal limits for these substances in drinking water. This draft list is subject to a 60-day public comment period before potential finalization by mid-November.

This action addresses growing public concern regarding plastic particles and pharmaceutical residues in water supplies. Studies have indicated the prevalence of microplastics in various bodily tissues, prompting scientific assessment of potential health risks. Similarly, the incomplete removal of pharmaceuticals by conventional wastewater treatment plants raises alarm.

While the EPA uses the list to guide research and funding, regulatory action has historically been rare. Nevertheless, environmental advocates like Judith Enck of Beyond Plastics view the inclusion as a crucial first step towards regulating microplastics in public water. Dr. Philip Landrigan noted that curbing plastic production is essential for meaningful impact.

The EPA's proposed list also identifies PFAS and disinfection byproducts as contaminant groups, alongside 75 chemicals and nine microbes. This initiative aligns with the MAHA agenda, which seeks to address various environmental issues, including plastic pollution and forever chemicals. The Safe Drinking Water Act mandates the EPA to review and publish this list every five years.
