Kalispell PFAS Rapid Response Project
Project: PFAS Rapid Response
Municipality: Kalispell, MT
Engineer: RPA
Watersurplus Contact: Jim Groose, Sr VP Municipal Water Treatment
Background: In July 2024, the City of Kalispell detected PFAS levels twice the limit established by the EPA in April of 2024 in its Grandview Wells site. Kalispell is one of two communities in Montana that have detected PFAS in their drinking water supply.
In response, the City of Kalispell approached WaterSurplus to design a proposed solution that not only promised rapid deployment but also provided proven treatment technologies for PFAS removal. WaterSurplus designed, fabricated, and delivered three WaterPlus pre-engineered quadplex 54” x 54” PFAS removal skids using anion exchange resin, contributing to Kalispell’s first-ever PFAS removal systems.
Solution: WaterSurplus deployed this anion resin-based PFAS Rapid Response system, started it up, and began treatment in a matter of months. This resulted in non-detectable PFAS levels and restored Kallispell’s freshwater well production using a system that required a significantly smaller footprint than a granular activated carbon system would have required.
