17 May 2022, Boston, Massachusetts: The health risks and contamination associated with per- and polyfluoroalkyl substances (PFAS) are propelling state and federal legislators to crack ...
Highly affected U.S. states, such as Michigan, New York, and New Jersey have sought to implement their own regulatory limits on PFAS concentrations in drinking water ahead of a slower moving federal government. Now, with the U.S. Environmental Protection Agency in the position to crack down on these chemicals in various water sources, including implementing drinking water maximum contaminant levels for PFOA & PFOS by Fall 2023, all states find themselves in the position of growing PFAS remediation need.
With state and federal governments increasing their focus on PFAS regulations, public water systems, including investor-owned utilities, will need to make significant investments to meet existing and impending standards. Bluefield estimates total annual expenditure for PFAS treatment systems across the U.S. to grow from US$335.0 million in 2022 to US$1.1 billion in 2030.
While the US$1.2 trillion Infrastructure Investment and Jobs Act (IIJA) ushers in US$55 billion of newly dedicated water sector investment, it also includes a sizeable US$10 billion for fiscal years 2022-2026 devoted to addressing contaminants of emerging concern. Central to the focus of this funding is the chemical class known as per- and polyfluoroalkyl substances.
Globally, per- and polyfluoroalkyl substances (PFAS) are gaining priority as a real water concern. This has been demonstrated by recent policy proposals in Europe seeking to rein in the usage of these manmade chemical substances that are increasingly found in drinking water supplies.
On 29 July 2021, the State of California Office of Environmental Health Hazard Assessment proposed Public Health Goals (PHGs) for drinking water concentrations of the synthetic chemicals PFOA (perfluorooctanoic acid) & PFOS (perfluorooctane sulfonic acid).
