Lake Jackson Water Hardness & Quality Report (2026)

The City of Lake Jackson operates the municipal water utility serving approximately 27,529–28,750 residents in Brazoria County, Texas. Water is sourced from 12 groundwater wells tapping the Gulf Coast/Chicot Aquifer and surface water purchased from the Brazosport Water Authority, derived from the Brazos River. The city's treatment facilities apply chloramine disinfection to ensure pathogen control throughout the distribution system. Emergency customer service is available 24/7 at 979-415-2400, and the main office is located at 25 Oak Dr, Lake Jackson, TX 77566.

The Brazos River watershed spans over 45,000 square miles, originating in the Texas Plains and flowing through diverse geological provinces to the Gulf of Mexico. Groundwater from the Chicot Aquifer, part of the broader Gulf Coast Aquifer System, moves through Pleistocene sands and clays overlying calcareous formations. Limestone-rich layers including elements from the Beaumont Formation contribute dissolved calcium and magnesium, yielding a hard supply with elevated natural mineral content.

Very hard water promotes scale buildup in pipes, heaters, dishwashers, washing machines, and water fixtures, reducing efficiency, shortening appliance lifespan, and increasing energy costs. Soap scum forms readily, diminishing lathering and leaving residues on skin, hair, and laundry. Regular descaling of affected appliances, installing sediment filters, and flushing hot water heaters are recommended maintenance steps. Water softeners are strongly recommended via ion exchange to prevent mineral accumulation. The 2023 Drinking Water Quality Report confirms compliance with all federal EPA requirements; TCEQ oversees monitoring, with past concerns including Naegleria fowleri control via chloramine residuals.
