EPA Designates Forever Chemicals as Hazardous Substances
/Synthetic human-made chemicals called PFAS have been rapidly infiltrating many of the world’s vital water supplies, damaging Earth’s environment in the process. These per-and polyfluoroalkyl substances (PFAS) are incredibly difficult to break down, often lasting for thousands of years, even contaminating rainfall in certain regions. With increasing knowledge over the last few decades, the United States Environmental Protection Agency (EPA) has decided to submit an official proposal to classify many of these chemicals as hazardous substances, influencing many additional federal protocols associated with their use and disposal. The decision also comes as new research has been exploring better ways for PFAS management and disposal.
Many PFAS are common household products like cooking pans, oils, cleaning supplies, and abrasives. PFAS chemicals often produce coatings and products that can repel water, oil, heat, and grease. The chemicals are dangerous because they break down slowly and have been observed leaching into water and soil, leaving trace amounts detectable in the blood of humans and animals.
Recent studies about the effects of exposure to PFAS suggest earlier assumptions were incredibly limited concerning the risks and knowledge of dangerous exposure levels. Prolonged exposure can result in reproductive complications, heart issues, respiratory disease, cancer, and immunosuppressant responses in communities. PFAS causes various complications as they primarily settle in the body’s blood, kidneys, and liver. These chemicals have been in the commercial market since the 1940s, and previous studies suggest they are present in more than 98 percent of the US population.
The EPA’s submitted proposal will list at least two of these harmful PFAS as hazardous substances, encouraging effective waste management at facilities that handle these chemicals, with much more likely to be added later. The Federal Drug Administration and many chemical manufacturers have already voluntarily phased out the use of these chemicals, especially in commodities that deal directly with food products. However, the unfortunate reality still suggests more than 70 percent of imported products still contain remnants of older PFAS. Since these chemicals are so slow to break down, they easily contaminate products transported into air, dust, food, ground soil, and water.
The EPA’s decision to begin managing PFAS use and disposal has had to navigate complicated relationships with the prominent chemical industry leaders, but at the neglect of community and environmental health. Critics of the EPA’s new proposal claim the action is a little too late, without any real repercussions or plans to mitigate the damages from the prolonged incorporation of these harmful chemicals in American communities. The other misfall of the EPA’s new proposal is that it fails to address any future solutions, only acknowledging current problems and only a few harmful PFAS.
There is little acknowledgment in the proposal to develop plans for future mitigation as these hazardous chemicals continue to leach into the environment and are already waning vital resources of fresh water. Although the proposal may lack future mitigation efforts, chemical scientists have been researching how to dispose of these chemicals effectively, and there may still be some good news.
Scientists have discovered that effective use of heat in contaminated water can initiate a chemical reaction to break down the strong PFAS bonds, removing them from the water without any remaining byproducts. This new information means water processing plants can effectively remove the harmful PFAS from water without releasing any byproducts into the environment, gradually diminishing their communal effects globally.
