Oxidation by electrochemistry can treat PFAS-laden waters without creating a secondary waste stream. Traditionally, other water treatment methods only remove PFAS constituents and concentrate them into a waste stream that must then be disposed.
On April 28, 2022, ten water organizations representing American utilities that treat public wastewater, drinking water, stormwater, and reuse water, submitted a letter to Congress for an exemption from PFAS liability under CERCLA.
January saw 29,000 counterfeit water purifying filters from China. The problem is that not only will contaminants remain in your water, but fake filters can also leach chemicals into otherwise clean taps.
Confusion created around PFAS testing requirements for industrial stormwater. While the EPA permit (MSGP) is very detailed on what operators need to do if they reach or exceed the screening level for PFAS, it is not clear on how to practically sample in New Mexico's arid desert.
Since EPA has not yet finalized their methodology for measuring PFAS in non-drinking water, the Department of Defense has defined a methodology to sample and analyze 40 PFAS in environmental media (water, soil, air) to meet requirements under CERCLA, CWA, and RECRA.
Rather than attempting to find sources of PFAS (polluters) via large sampling programs of stormwater effluent, some states are requesting, requiring, or ordering local wastewater treatment plants to provide PFAS concentration data.
