    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.

    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 ...

    In humans, PFHxS binds to blood albumin, [8] and relatively little PFHxS is found in the liver compared to longer chain PFASs such as PFOS. [9] The half-life of PFHxS in adult blood serum is 5.3 years (4.7 years for women and 7.4 years for men). [10] The half-life of PFASs in human blood generally decreases with decreasing backbone (CF 2) length.

    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.
