Discover why the EPA targets six PFAS chemicals for new regulations, focusing on their health risks, prevalence, and extensive scientific research. ... Additionally, the EPA added a hazard index ...
Even at very low doses, PFAS can pose health risks. The EPA’s minimum reporting level – the lowest concentrations reliably measured by most laboratories – for some PFAS are measured in parts ...
In April 2024, the EPA announced the final National Primary Drinking Water Regulations (NPDWR) for six PFAS compounds, specifying a maximum contaminant level (MCL) of 2000 parts per trillion (ppt) for PFBS and a "hazard index" limit on mixtures of PFBS, PFHxS, PFNA and HFPO-DA. [9] [10]
Of the 66,000 public drinking water systems impacted by the new standards, the EPA estimates that between 4,100 and 6,700 will eventually have to take action to reduce PFAS contamination.
The CompTox Chemicals Dashboard is a freely accessible online database created and maintained by the U.S. Environmental Protection Agency (EPA). The database provides access to multiple types of data including physicochemical properties, environmental fate and transport, exposure, usage, in vivo toxicity, and in vitro bioassay.
The standards, enforced by EPA and state agencies, require all public water systems in the U.S. to monitor for GenX and treat their water, if necessary to meet the 10 ppt standard. [43] EPA also announced the availability of grant funds to assist small and disadvantaged communities in testing for and treating PFAS contamination in their water ...

EPA created the database to provide a consistent approach to risk assessment practices across the various environmental laws that the Agency implemented and enforced. [citation needed] The program was created by the EPA in 1985. Initially, the goal of the program was to foster consistency's in the agency's evaluation of chemical toxicity. [1]
