Kilgore Water Hardness & Quality Report (2026)

The City of Kilgore Water Utilities is the provider of drinking water for about 15,000 customers across Gregg and Rusk Counties in Texas. Water originates from the Sabine River, which feeds a reservoir located next to the city's water treatment facility. After treatment, the water is distributed to homes and businesses in Kilgore and nearby communities. The utility utilizes a standard surface water treatment process, incorporating coagulation, sedimentation, filtration, and disinfection to ensure the water meets all state and federal drinking water regulations.

The Sabine River watershed covers more than 10,000 square miles of East Texas, an area marked by gently rolling hills and pine forests. Underlying this region are Cretaceous bedrock formations, including chalky limestones and shales. As the river travels southeast, it dissolves calcium and magnesium from these rocks, giving the water a moderately hard quality. Any minor input from the Carrizo-Wilcox Aquifer, which contains minerals from sandstone and lignite, can further influence the water's mineral content, though the overall chemistry is largely dictated by the river's geological interactions.

This moderately hard water can lead to some scale buildup in appliances such as water heaters, dishwashers, and washing machines, potentially reducing their efficiency and causing spots on glassware. Homeowners might also notice soap scum forming on fixtures and find they need more detergent to create lather. While routine maintenance, like annual appliance deliming and using drain screens, can help manage these issues, installing a water softener is an option for those concerned about aesthetics or wanting to prolong the life of their appliances. The utility's 2022 report confirmed compliance with EPA standards for primary contaminants.
