Springfield Water Hardness & Quality Report (2026)

City Utilities of Springfield operates the water supply for Springfield and parts of Greene County, Missouri. The Fulbright Water Treatment Plant utilizes Fulbright Spring, a deep well, and McDaniel Lake, while the Blackman Water Treatment Plant draws from Fellows Lake and the James River, with supplementation from Stockton Lake as needed. An additional deep well in the distribution system provides backup capacity. These mixed surface and groundwater sources serve approximately 170,000 residents in the city and surrounding areas.

The watershed encompasses the James River basin within the Springfield Plateau section of the Ozark Plateaus, characterized by karst topography developed on Mississippian limestones and dolomites. Surface waters from Fellows, McDaniel, and Stockton Lakes interact with these carbonate formations, while Fulbright Spring and deep wells directly access groundwater from the Ozark Aquifer. This geology contributes to a hard supply through dissolution of calcium- and magnesium-bearing minerals from the Burlington and Keokuk Formations and Springfield Formation dolomites.

At this hard level, scale buildup occurs in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and lifespan. Soap scum forms readily, and spotting appears on glassware and fixtures. Regular maintenance including deliming appliances and using high-efficiency detergents helps mitigate these issues; a water softener is recommended to prevent long-term plumbing and appliance damage. The 2025 Consumer Confidence Report indicates no violations for fecal coliform or E. coli; conventional treatment including coagulation, sedimentation, filtration, and disinfection is applied at both plants, with ongoing monitoring for potential contaminants from urban and agricultural runoff in the watershed.
