Pearland Water Hardness & Quality Report (2026)

The City of Pearland Water Utility serves Pearland, Texas, operating a mixed water supply system. The utility manages 10 groundwater wells drawing from the Evangeline and Chicote aquifers, supplemented by surface water purchased from the City of Houston and Gulf Coast Water Authority through two connection points. A third connection with Clear Brook City MUD exists but is not currently utilized. Combined, the system produces approximately 3.5 billion gallons of clean drinking water annually to serve the community.

Pearland's water supply is part of the Gulf Coast Watershed. Groundwater from the Evangeline and Chicote aquifers naturally contains elevated levels of dissolved minerals, particularly calcium and magnesium, due to the geological composition of these aquifers. Surface water contributions sourced through agreements with the City of Houston and Gulf Coast Water Authority add to the overall mineral content, creating a consistently mineralized and very hard supply across both sources.

Very hard water in Pearland causes significant limescale buildup on showerheads, faucets, and inside pipes and appliances, with water heaters, dishwashers, washing machines, and plumbing fixtures experiencing accelerated wear and reduced efficiency. Whole-home water softeners using ion-exchange processes are recommended to prevent scale formation at the source; regular descaling and periodic maintenance are necessary mitigation strategies. Third-party testing has detected arsenic above health guidelines, occurring naturally in soil and bedrock in the region. The utility produces an annual Consumer Confidence Report covering all testing each year, and reverse osmosis systems are available for homeowners concerned with drinking water purity and taste improvement.
