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.
Earlier this year, the Food and Drug Administration said it found 31 different PFAS, in 570 cosmetic products, over the 12 months ending in March 2023. ... Instead, choose products made from ...
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 ...
The analysis found 66, or 14%, of all active ingredients in pesticides are PFAS, which are intentionally added to improve the product’s ability to eliminate pests, Andrews said.
One of twenty deer tested near Clark's Marsh was found to have a PFOS level of 547 parts per billion (ppb) taken from a muscle sample. It is unknown how PFAS could accumulate to the level seen in the deer found near Clark's Marsh. All deer except the one with elevated levels at Clark's Marsh were found to have no or very low levels of PFAS ...
The risks of PFAS, sometimes known as "forever chemicals," have long been known. But it's more complicated than it sounds.
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.
What are PFAS? Per- and polyfluorinated alkyl substances, or PFAS, are a group of nearly indestructible chemicals that build up in the human body over time. Known as "forever chemicals," they’ve ...
