Modern study It turns out that technologies installed to remove eternal chemicals from drinking water also do twice, removing harmful other materials-in these, some substances associated with some types of cancer.
. testPublished on Thursday in the ACS ES & T Water journal, it appears when the Trump administration draws a principle ordering water systems to take action to spotless chemicals in drinking water forever.
Per- and polyphluoralkilic (PFA) substances, commonly referred to as eternal chemicals, are the class of thousands of chemicals that do not degrade in the environment and have been associated with lots of disturbing health results, including various cancers, hormonal disorders and developmental delays. Because they do not degrade, they are extremely ubiquitous: a 2023 study From the American geological examination, it estimated that 45 percent of the US tap water may contain at least one PFAS chemicals.
Last year, the Biden administration finalized the principle establishment The first legal boundaries in drinking water in history, setting strict boundaries for six types of PFAS chemicals and ordering that the water tools needed to spotless drinking water at these borders until 2029. But in May, the Environmental Protection Agency stated that this would be re -considering the provisions regarding four of the six chemicals in the original principle and extend the current principle and extend the current two years. Changes appear after universal indignation from water tools who to talk that the costs of installing PFAS filtration systems would be much beyond what the agency originally estimated.
“Based on historical activities aimed at taking care of PFA during the first Trump administration, EPA deals with PFA from all our program offices, developing research and tests, stopping PFA before entering drinking water systems, pulling pollutant responsibility and not only” – said Brigit Hirsch, press secretary of EPA, said in the statement. “This is just a fraction of the work that the agency performs on PFA during the second term of President Trump so that the Americans have the purest air, earth and water.”
Hirsch also emphasized that as part of the EPA standards again, the four chemicals resident in question, “it is possible that the result may be more stringent requirements.”
Experts say that PFA cleaning costs can bring different benefits, apart from obtaining, they believe chemicals from the supply of Americans. The authors of the fresh study – all employees of the Environment Working Group (EEC), non -profit organization that conducts research on chemical safety – this technology that gets rid of PFA can also filter a number of other harmful substances, including some created as by -products of the water treatment process itself.
In the study, there are three types of water filtration technologies, which have been proven that they remove PFA. These technologies “are really widespread, they have been used for a really long time and are well documented to remove a large number of pollution,” says Sydney Evans, a senior analyst at EEC and co -author of the report.
Most routine water disinfection processes in the USA entail the addition of chemicals – usually chlorine – into water. Although this process removes harmful pathogens, it cannot rinse PFA or other types of impurities, including bulky metals and elements such as Arsen.
