Acknowledging @Gprp’s comment about EGL only at very early stage of PFAS technology the scale of the problem is huge so worth EGL pursuing?

“The US Environmental Protection Agency (EPA) has identified more than 120,000 locations around the US where people may be exposed to a class of toxic “forever chemicals” associated with various cancers and other health problems that is a frightening tally four times larger than previously reported, according to data obtained by the Guardian.

The list of facilities makes it clear that virtually no part of America appears free from the potential risk of air and water contamination with the chemicals known as per- and polyfluoroalkyl substances (PFAS).

Colorado tops the EPA list with an estimated 21,400 facilities, followed by California’s 13,000 sites and Oklahoma with just under 12,000. The facilities on the list represent dozens of industrial sectors, including oil and gas work, mining, chemical manufacturing, plastics, waste management and landfill operations. Airports, fire training facilities and some military-related sites are also included.

The EPA describes its list as “facilities in industries that may be handling PFAS”. Most of the facilities are described as “active”, several thousand are listed as “inactive” and many others show no indication of such status. PFAS are often referred to as “forever chemicals” due to their longevity in the environment, thus even sites that are no longer actively discharging pollutants can still be a problem, according to the EPA.

The tally far exceeds a previous analysis that showed 29,900 industrial sites known or suspected of making or using the toxic chemicals.”
