At the time, PFAS levels in drinking water were not regulated, though the federal government had non-enforceable “health advisory” levels for how much of the chemicals can be in drinking water ...
The EPA, which regulates public drinking water, advises a safety level of below 70 parts per trillion for the two most-studied PFAS chemicals. This is considered voluntary guidance. This is ...
The city of Salisbury, which serves an estimated 30,343 residents, was found to exceed safe PFAS levels by 400% in three tests in 20 which were completed. The results found two pollutants in the ...
Within three years, utilities which provide water to at least 15 service connections or 25 people will have to implement testing procedures and begin notifying the public about PFAS levels if they ...
Between 2016 and 2021 the U.S. Geological Survey (USGS) tested tap water from 716 locations across the United States, finding PFAS levels exceeding the EPA advisories in approximately 75% of samples from urban areas and in approximately 25% of rural areas. [80] In April 2024 EPA published final drinking water standards for six PFAS: PFOA; PFOS
The agency's health advisory level for the combined concentrations of PFOA and PFOS is 70 parts per trillion (ppt). [22] [23] In June 2020 the State of New Jersey published a drinking water standard for PFOA, the first state to do so. Public water systems in New Jersey are required to meet a maximum contaminant level (MCL) standard
The U.S. Environmental Protection Agency on Wednesday announced new drinking water standards limiting levels of per-and polyfluoroalkyl substances (PFAS), also known as "forever chemicals," which ...
For example, Minnesota recommends a guidance value of 0.027 μg/L for PFHxS, [23] and Michigan has a screening level of 0.084 μg/L for PFHxS. [4] In 2020, Michigan adopted drinking water standards for 5 previously unregulated PFASs including PFHxS, which has a maximum contaminant level (MCL) of 51 parts per trillion (ppt) or 0.051 μg/L.
