In a one-hour presentation before the Pease Restoration Advisory Committee Amy Quintin of Wood PLC outlined the process of determining the human health risk posed by the flow of the PFOS/PFOA/PFBS chemicals from the former Pease Air Force Base.
Quintin explained the process of where the chemicals are coming from and going to, how and where might people come into contact with the chemicals, how much is present at those locations, and whether the levels at those locations are unsafe.
She concluded that soil, surface water and sediment are safe for current use such as swimming and wading. However, concentrations in shellfish are unknown and that tissue sampling is proposed. Testing freshwater surface water/sediment samples are also proposed.
This was a lengthy report with many maps and scenerios for human exposure. This and previous reports to the Pease Restoration Advisory Board can be found at this location: https://www.afcec.af.mil/Home/BRAC/Pease-Archives/. The presentation from October 10, 2018 will be posted soon to this site.
