Microplastics in drinking water to get EPA scrutiny
The Environmental Protection Agency (EPA) has taken a significant step by proposing to include microplastics and pharmaceuticals on the list of contaminants in drinking water for the first time. This move could potentially lead to new limits on these substances for water utilities, addressing concerns raised by Americans about the safety of their drinking water.
EPA Administrator Lee Zeldin acknowledged the public’s worries about plastics and pharmaceuticals in drinking water and emphasized the agency’s commitment to addressing these issues. The proposal is also seen as a response to the pressure from Health Secretary Robert F. Kennedy Jr.’s MAHA movement, which has been advocating for stricter regulations on environmental contaminants.
The EPA’s Contaminant Candidate List identifies contaminants in drinking water that are not currently regulated under the Safe Drinking Water Act. The agency has released the draft of the sixth version of the list, initiating a 60-day public comment period before finalizing it by mid-November.
Studies have shown the presence of microplastics in drinking water and their potential impact on human health. Similarly, concerns have been raised about pharmaceutical drugs entering the water supply through human excretion and inadequate removal by wastewater treatment plants.
While the EPA uses the list to prioritize research and regulatory decisions, it rarely sets limits for pollutants in public drinking water based on the list. Despite criticism from some environmental advocates about the limited impact of the listing, others view it as a positive first step towards regulating microplastics in water supplies.
Dr. Philip Landrigan of Boston College emphasized the importance of addressing the root cause of plastic pollution to make a meaningful difference. The U.S. is participating in global discussions on a treaty to tackle plastic pollution, but there is resistance to imposing limits on plastic production.
Kennedy’s MAHA movement has been actively engaging with the EPA on various environmental issues, including plastic pollution and pesticide regulation. The EPA has hinted at an upcoming MAHA agenda that will address key issues such as forever chemicals, food quality, and lead pipes.
In addition to the proposed listing of microplastics and pharmaceuticals, the EPA’s draft list includes other contaminant groups like PFAS and disinfection byproducts. The agency is seeking public feedback on the draft list before finalizing it.
Overall, the EPA’s proposal to include microplastics and pharmaceuticals on the list of contaminants in drinking water marks a significant step towards ensuring the safety and quality of drinking water for all Americans. The agency’s efforts to address emerging environmental challenges are crucial in safeguarding public health and the environment.
