US EPA proposes for the first time to limit ‘chemicals forever’ in drinking water

The United States Environmental Protection Agency has advocated national standards for a number of chemical pollutants related to PFAS – per- and polyfluoroalkyl substances. Scientific studies have shown that these substances pose a health hazard.

The EPA’s proposed standards would cover six PFASs that contaminate drinking water in the United States. Prior to this, individual states had already imposed restrictions on the relevant particles. However, this is the first time the EPA has proposed national regulations. The list would include: For PFOC and PFOS, the agency has set the maximum allowable concentration at 4 particles per trillion particles of water. For other substances, the EPA has proposed limits based on a hazard index, which is calculated from the cumulative effects of chemicals. Fully implemented, the rule would prevent thousands of deaths and reduce tens of thousands of PFAS-related illnesses. The EPA’s own estimate is that passing the reforms and implementing them would cost about $772 million a year. But a study commissioned by the AWWA suggests the cost could be around $2.9 billion a year. The EPA says more than $9 billion is already available through the US Infrastructure Act passed in late 2021, but the AWWA estimates the cost over 20 years at $58 billion. The EPA first warned of PFAS in drinking water in 2001, but was never able to approve a national limit. PFAS include approximately 14,000 chemicals commonly used to protect various consumer products from water, heat and contamination. These chemicals are called “forever” due to the fact that they do not break down naturally. Various studies have linked PFAS to the development of cancers, autoimmune disorders, liver and kidney damage, and other serious diagnoses.

The United States Environmental Protection Agency (EPA) has advocated national standards for a number of chemical pollutants related to PFAS – per- and polyfluoroalkyl substances. Scientific studies have shown that these substances pose a health hazard.

The standards proposed by the EPA would cover six PFAS that contaminate drinking water in the United States. Prior to this, individual states had already imposed restrictions on the relevant particles. However, this is the first time the EPA has proposed national regulations. The list would include:
perfluorooctanoic acid (PFOA)
perfluorooctane sulfonic acid (PFOS)
perfluorononanoic acid (PFNA)
perfluorohexane sulfonic acid (PFHxS)
perfluorobutane sulfonic acid (PFBS)
hexafluoropropylene oxide dimer acid (HFPO-DA, commonly known as GenX compounds).

For PFOC and PFOS, the agency has set the maximum authorized concentration at 4 particles per trillion water particles. For other substances, the EPA has proposed limits based on a hazard index, which is calculated from the cumulative effects of chemicals.

“It’s a huge deal, in terms of protecting public health, but also in terms of what it will take to accomplish,” says Michelle Crimi, an environmental engineer at Clarkson University in Potsdam, New York.

The EPA also offers:

Monitor these PFAS by implementing specific requirements for its levels. They are based on the EPA’s long-standing general principles that the frequency of monitoring depends on past results.
Inform the public of the levels of these PFAS. Public water system operators would be required to notify the public if PFAS levels are found to exceed those required by proposed regulatory standards.
Reduce levels of these PFAS in drinking water if they exceed proposed standards. Water utility managers will be required to take action to reduce PFAS levels in drinking water if these are exceeded under proposed regulatory standards
The agency said it expects final approval of the regulations by the end of the year, adding that if fully implemented, the rule would prevent thousands of deaths and reduce dozens. thousands of PFAS-related illnesses.

“For facilities large and small, adding PFAS filtration will need to be balanced against other priorities, such as replacing lead pipes,” says Chris Moody, regulatory analyst at the American Water Works Association ( AWWA).

The EPA’s own estimate is that passing the reforms and implementing them would cost about $772 million a year. But a study commissioned by the AWWA suggests the cost could be around $2.9 billion a year. The EPA says more than $9 billion is already available through the US Infrastructure Act passed in late 2021, but the AWWA estimates the cost over 20 years at $58 billion.

The EPA first warned of the presence of PFAS in drinking water in 2001, but was never able to approve a national limit.
Scientists discover an easy way to destroy ‘chemicals forever’

PFAS include approximately 14,000 chemicals commonly used to protect various consumer products from water, heat and contamination. These chemicals are called “for all timedue to the fact that they do not break down naturally. Various studies have linked PFAS to the development of cancers, autoimmune disorders, liver and kidney damage, and other serious diagnoses.
