Water Quality in Watertown, SD

Like most of South Dakota, Watertown 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 Watertown also receive chlorinated water that, while safe, affects taste and can cause dryness for skin and hair. Well water users in the Watertown area should test regularly for hardness, iron, nitrates, and bacteria — and increasingly, PFAS compounds that have been detected across the Midwest.

Watertown SD Water Quality

As our headquarters city, Applied Water Technologies knows Watertown water better than anyone. The city’s water is sourced from Kampeska Lake and is treated before distribution, but arrives at homes with very high hardness (18–24+ GPG), noticeable chlorine for taste and odor, and iron levels that vary across the distribution system.

Watertown residents see the effects of hard water every day — white scale on faucets and showerheads, reduced appliance life, and frustrating soap performance. Owner Joel Urban and the Applied Water team have solved these problems for thousands of Watertown families since we opened here.
