City begins treating Grandview Well for forever chemicals

A forever chemical treatment system installed last week at Kalispell's Grandview Wells site is expected to be operational in the coming days.

Testing done in July found one of the two Grandview Wells to contain forever chemical levels twice the limit established by the Environmental Protection Agency in April 2024. 

Forever chemicals, scientifically known as per- and polyfluoroalkyl substances, or PFAS, were first detected in Kalispell’s public water supply during sample testing in March and June of 2022. The Armory Well, which sits next to a former armory and is near Kalispell’s airport, contained trace amounts of PFOS, part of the PFAS family.
