Des Moines Water Utilities Join “Forever Chemicals” Lawsuit


Josie Taylor | July 27, 2022

Trustees of two Des Moines metro area drinking water producers have voted to join hundreds of civil claims against manufacturers of firefighting foams that contain PFAS, also known as “forever chemicals,” which have contaminated Iowa water.

Des Moines Water Works and West Des Moines Water Works are pursuing the litigation to help offset anticipated future costs to remove the chemicals from their treated water. Tests of both systems’ drinking water in recent months have revealed concentrations of PFAS chemicals that exceed federal health advisories.

The U.S. Environmental Protection Agency is expected to set enforceable limits on the chemicals that could force water utilities to remove them as part of their treatment processes. Recent tests of the treated water that might again reveal PFAS contamination are pending.

Firefighting foam is a potential source of contamination in West Des Moines, and it’s the subject of the multi-state lawsuit that the two metro utilities recently voted to join. These utilities were approached by law firms that are helping litigate it.

The foam is believed to have contaminated groundwater near military bases, airports and other sites.
