Scheduling a Private Well Sample Related to the Muddy Branch PFAS

The County was notified in May of elevated PFAS levels in local streams. These levels are significantly higher than naturally expected, and ingesting stream water or eating fish from the area may pose health risks. More information and FAQs are available at MontgomeryCountyMD.gov/MuddyBranch.

As a precaution, the County is offering drinking water well testing within a 1?mile radius of the highest MDE sampling results. Residents in this area were contacted directly by the County.
