Chemicals known as PFAS, commonly called “forever chemicals”, were found in treated drinking water that goes to homes, businesses and schools in parts of West Des Moines. The contamination was discovered by the Iowa Department of Natural Resources.
The DNR is testing water in at least 59 cities at their sources and after treatment for human consumption. West Des Moines, the sixth-largest city in the state, was the only city to have detectable levels of two prominent PFAS in its treated drinking water, according to early results obtained by Iowa Capital Dispatch.
Based on the recent DNR test results, at least three of West Des Moines Water Works’ groundwater wells have the two most-studied PFAS, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). It’s unclear why the wells have the chemicals.
The chemicals have been commonly used in nonstick cookware and stain-resistant clothes and furniture. Groundwater contaminations in Iowa have been previously identified near airports, which have used firefighting foams that have the chemicals. To learn more about PFAS more generally, click here.
Concerns about the chemicals have grown in recent years because researchers have shown they can cause cancers and are widely distributed in the environment. The vast majority of people in the United States are believed to have detectable amounts of PFAS chemicals in their bodies.
