The type of PFAS remediation technology selected is often a reflection of the PFAS contamination levels and the PFAS signature (i.e. the combination of short and long chain PFAS substances present) in conjunction with the site specific water chemistry and cross contaminants present in the liquid stream.
The new drinking water standard would limit contamination from six of the most toxic PFAS compounds by requiring water utilities to test for their presence and then take action to remove the ...
Last year, 3M reached a settlement worth $10.3 billion with water systems across the U.S. that will help pay to clean up drinking water contaminated with PFAS, while DuPont de Nemours Inc ...
Following initial discoveries of groundwater contamination in 2002, the Minnesota Department of Health conducted numerous studies –concluding in 2008, 2010, and 2014 – on the level of PFAs found in the bloodstreams of exposed residents. On February 20, 2018, the state of Minnesota settled its lawsuit against 3M in exchange for $850 million.
The U.S. Environmental Protection Agency on Wednesday issued new drinking water standards, directing public utilities to ensure the level of PFAS remains at a safe level for communities.Advocates ...
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. In April 2024 EPA published final drinking water standards for six PFAS: PFOA; PFOS
The EPA’s new standard is the first ever nationally for PFAS in drinking water. It sets limits of 4 parts per trillion for PFOA and PFOS and 10 parts per trillion for PFNA, PFHxS and “GenX ...
In 2024, a worldwide study of 45,000 ground water samples found that 31% of samples contained levels of PFAS that were harmful to human health; these samples were taken from areas not near any obvious source of contamination. Soil is also contaminated and the chemicals have been found in remote areas such as Antarctica.
