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.
Most sources of PFAS pollution are from firefighting, industry wastewater discharge, and landfills, and humans are generally exposed to PFAS through diet and drinking water. PFAS are associated with adverse health effects, such as cancer , decreased fertility , and impact on child development.
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 ...
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 ...
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.
In the new EPA regulations, PFOA and PFOS, two of the most well-studied and potentially toxic chemicals, cannot exceed 4 parts per trillion in drinking water. The prior health advisory set a limit ...
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 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 ...
