The EPA will begin regulating the six PFAS substances in public drinking water systems across the country on June 25. Anna Reade, PhD., director of PFAS Advocacy at the Natural Resources Defense ...
PFAS, or per- and polyfluorinated substances, were invented in the late 1930s and have been used to make coatings and products that resist heat, grease, stains, oil and water, according to the ...
All of these methods promote the formation of hydroxyl radicals or other oxidizing agents that can oxidize PFAS and break its C−C bonds. [3] [4] However, the remediation of PFAS depends on the environmental medium where the these compounds reside. For example, the treatment of contaminated soil, biosolids and water is not the same, and risk ...
Used since the 1950s to make consumer products nonstick, oil- and water-repellent and resistant to temperature change, PFAS chemicals have been linked to serious health problems, including cancer ...
Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic organofluorine chemical compounds which have been studied extensively due to potential human health concerns. Regulations for some PFAS compounds in public water systems have been published in the 21st century.
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 Red List and the Living Building Challenge. The Living Building Challenge includes seven performance categories, titled as petals. The red list falls under the materials petal. A building project may not contain any of the Red List chemicals or chemical groups. There is an exception for small components in complex products. [4]
San Pellegrino's sparkling water is solidly in the safe zone when it comes to PFAS levels at .31 ppt ("safe" PFAS levels are seen as being below 1 ppt). If you've yet to try their Essenza cans ...
