Alliance Water Hardness & Quality Report (2026)

The City of Alliance, Ohio operates a municipal water utility serving approximately 22,322 residents in Stark County. The system draws from surface water sources in the Mahoning River watershed and operates treatment facilities employing biological filtration, conventional filtration, chlorine, and chlorine dioxide disinfection. The utility is located at 12251 Rockhill Avenue NE, Alliance, OH 44601 and can be reached at 330-829-2241. The system meets or exceeds federal Safe Drinking Water Act standards according to the 2024 Consumer Confidence Report, which confirms no regulatory violations.

Alliance's water supply originates from the Mahoning River watershed, which flows through northeastern Ohio's Appalachian region. The underlying geology consists primarily of Pennsylvanian-age sandstones and shales with interbedded coal seams, underlain by Devonian and Carboniferous limestone formations. These carbonate rock layers are highly soluble, causing groundwater and surface runoff to dissolve significant quantities of calcium and magnesium minerals. This geological setting produces a hard water supply typical of the region.

Alliance's hard water supply creates practical challenges for residents and municipal infrastructure. Scale accumulation in water heaters, pipes, and appliances accelerates noticeably, reducing efficiency and lifespan. Dishwashers, washing machines, and water heaters are particularly vulnerable to mineral buildup, and soap and detergent effectiveness diminishes, requiring higher doses for cleaning. A water softener is commonly recommended for households to mitigate these effects and reduce long-term maintenance costs and energy consumption. The utility has reported three contaminants above EPA health-based guidelines (MCLGs); treatment includes conventional filtration and disinfection with chlorine and chlorine dioxide. Residents are advised to review the annual Consumer Confidence Report for detailed contaminant monitoring data.
