Lexington Water Hardness & Quality Report (2026)

The City of Lexington Water Company supplies drinking water to about 11,479 residents in Lexington, Nebraska. Operating from 406 E 7th Street, the utility draws all its water from groundwater sources, which are then treated before reaching the public. Lexington's water originates in the High Plains Aquifer, a vast underground reservoir stretching across the Great Plains. This aquifer is composed of sand and gravel layers from the Quaternary period resting atop sediments of the Tertiary Ogallala Formation. As the groundwater travels through these layers and the underlying limestone and chalk, it picks up substantial amounts of calcium and magnesium, leading to the water's characteristic hardness.

The High Plains Aquifer system in this area features Quaternary sand and gravel deposits overlying the Tertiary Ogallala Formation; groundwater passing through limestone and chalk layers dissolves calcium and magnesium, resulting in hard water.

Homeowners in Lexington will likely observe scale deposits forming in appliances like water heaters and kettles over time. You might also notice that soap doesn't lather as easily, and dishes and glasses could come out of the dishwasher spotted. To combat these issues and help your appliances last longer, installing a water softener is a good idea. The City of Lexington Water Company has also noted potential contamination concerns, including copper and certain chemicals like dinoseb. For the most current information on water quality testing, treatment processes, and regulatory compliance, it's best to review their latest Consumer Confidence Report.
