The US Environmental Protection Agency (EPA) announced that it will improve transparency of environmental enforcement by making their Enforcement and Compliance History Online (ECHO) tool integrated with environmental justice (EJ) metrics.
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.
