New Mexico Environmental Department's handling of the 2021 MSGP certification 
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.
