Water Quality in Sioux Falls, SD

Like most of South Dakota, Sioux Falls faces common regional water quality challenges. Groundwater here typically carries elevated hardness (calcium and magnesium minerals), often combined with iron that causes staining on fixtures and laundry. Municipal customers in Sioux Falls also receive chlorinated water that, while safe, affects taste and can cause dryness for skin and hair. Well water users in the Sioux Falls area should test regularly for hardness, iron, nitrates, and bacteria — and increasingly, PFAS compounds that have been detected across the Midwest.

Sioux Falls Water Quality Overview

Sioux Falls draws its municipal water primarily from the Big Sioux River and Big Sioux Aquifer. The water is treated but arrives at taps with significant hardness (14–19 GPG), chlorination for disinfection, and occasional elevated iron in some parts of the distribution system. Sioux Falls has a growing population and expanding service area — water quality can vary by neighborhood and pipe age.

For homeowners in the newer western suburbs of Sioux Falls as well as older neighborhoods near downtown, a complete water treatment approach typically includes a Hague water softener for whole-house hardness removal combined with an RO system for premium drinking water. See our complete water softener guide for system options.
