East Independence Water Hardness & Quality Report (2026)

The City of Independence Water Department operates the Courtney Bend Water Treatment Plant in Jackson County, Missouri, serving approximately 250,000 people including Independence residents and 12 wholesale customers. Water is supplied from 42 groundwater wells drawing from the Missouri River Alluvial Aquifer, a Quaternary-age deposit underlying the Courtney Bottoms north of Independence. The well water is softened and disinfected at the treatment plant before distribution. The utility consistently meets or exceeds all federal and State of Missouri drinking water standards with no maximum contaminant level violations.

The Missouri River Alluvial Aquifer is a shallow groundwater system fed by precipitation and surface water infiltration, underlying the Courtney Bottoms alluvial plain. The aquifer overlies Paleozoic limestone and dolomite formations, which contribute dissolved minerals as groundwater percolates through the aquifer matrix and carbonate bedrock below. This continuous mineral exchange produces the moderately hard character of the supply, reflecting the region's widespread carbonate geology and the aquifer's intimate contact with underlying Paleozoic formations.

At 124 mg/L, moderately hard water causes scale buildup in kettles, water heaters, and pipes, with reduced soap and detergent efficiency and spotting on glassware and fixtures. Dishwashers and washing machines are most affected. A water softener is recommended for households seeking to reduce these effects and extend appliance lifespan. The 2022 Consumer Confidence Report recorded a pH of 9.72, total alkalinity of 64 mg/L, calcium at 13.7 mg/L, and magnesium at 16.8 mg/L — all within acceptable drinking water parameters and reflecting the treated groundwater quality after softening and disinfection at the plant.
