PFAS & Water Quality in Des Moines, IA

Where Des Moines's drinking water comes from

Much of the Des Moines area's drinking water has long been tied to surface water from the Des Moines and Raccoon Rivers, which drain a heavily agricultural watershed across central Iowa, sometimes supplemented by groundwater and shallow wells along the rivers. The region tends to lean on these river sources, so the broad supply picture here is shaped by central Iowa's river systems and the farmland they flow through.

Around Des Moines, the system serving your address is the one that actually answers for your water, and homes across the metro can be on different public systems even within a few miles. So the city summary above is orientation, not your specific tap. When evaluating an address, identify the utility listed for it here, then read that utility's annual Consumer Confidence Report and call the contact it publishes. That free step lays out the real source and testing record for your street, which is genuinely worth reviewing.

Des Moines water hardness

Groundwater and river supplies across much of central Iowa tend to run hard, as a lot of Midwestern water over limestone-rich ground does, though that's a regional lean and not a number for your address. No hardness figure lives in the federal records behind this page. So if your showerhead keeps clogging and you'd like to decode that, a cheap test strip from the hardware store settles it, and your utility's annual report often lists hardness in the fine print.

Reading this when you're evaluating a Des Moines address

City-level numbers describe the broad pattern around Des Moines; two homes a mile apart can sit on different water systems with very different profiles. The address report fills that gap — it identifies the public water system serving a specific property, lists any PFAS detections on that exact system, and maps the nearby industrial and Superfund sources.
