IDEM 2020 Screening Levels Update

Polyfluoroalkyl substances (“PFAS”) continue to make waves, this time in the Hoosier State as the Indiana Department of Environmental Management (“IDEM”) announced at the beginning of March that three PFAS compounds are now listed in its annual “Screening Level” update. 

“With it’s annual updates, IDEM does a good job of keeping its screening levels refreshed with the latest scientific research,” says James Hogan, President & CEO of The ELAM Group. 

This year’s announcement could financially impact the regulated community more significantly than in year’s past as IDEM grapples with PFAS. Its announcement calls for publication following the U.S. EPA’s publication of PFAS screening levels. The U.S. EPA is currently moving forward with the development of enforceable levels for PFOA and PFOS. What’s more, IDEM has also added an Asbestos MCL. 

“With the new announcements about Asbestos and PFAS, environmental liability could become an even larger financial consideration than in years past,” cautions Hogan. 

IDEM’s 2020 Screening Level Tables (Table A-6 and A-7), effective March 2, 2020, have been published and are now available on IDEM’s website located at:  There is a 6 month transition period in place, ending on September 2, 2020.
