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 risks of PFAS, sometimes known as "forever chemicals," have long been known. But it's more complicated than it sounds.
The so-called “forever chemicals” − a name attributed to PFAS' centuries-long half-life − are ubiquitous: In addition to drinking water, they are found in everything from non-stick ...
Per-and polyfluoroalkyl substances are found in thousands of products most Americans use or come into contact with daily, such as: Food containers that have PFAs are waterproof and grease-proof ...
Perfluorosulfonic acids (PFSAs) are chemical compounds of the formula C n F (2n+1) SO 3 H and thus belong to the family of perfluorinated and polyfluorinated alkyl compounds (PFASs).
Some, but not all, studies in humans with PFAS exposure have shown that certain PFAS may affect growth, learning, and behavior of infants and older children, lower a woman's chance of getting pregnant, interfere with the body's natural hormones, increase cholesterol levels, affect the immune system, and increase the risk of cancer."
What the EWG found is that filters’ effectiveness at reducing PFAS in tap water varied. Here’s how some of the most popular filters stacked up in EWG’s tests. Travel Berkey : 100% removal of ...
PFAS accumulates in the body, which is why EPA set their limits for drinking water at 4 parts per trillion for two common types — PFOA and PFOS — that are phased out of manufacturing but still are present in the environment. Health experts say low doses of the chemicals can build up in the body over time, so even small amounts are a problem.
