Hurst Water Hardness & Quality Report (2026)

The City of Hurst utility in Tarrant County, Texas serves approximately 40,000 residents across a 10-square-mile area in the Dallas-Fort Worth metroplex. Treated surface water is purchased primarily from the Greater Tarrant Regional Water District and the North Texas Municipal Water District, with key reservoir sources including Lake Grapevine, Eagle Mountain Lake, and Lake Lewisville on the Trinity River system. No local treatment plants are operated; water is received post-treatment with chloramines for residual disinfection and distributed directly to customers.

The Trinity River watershed spans North Texas, with reservoirs impounded amid Cretaceous formations such as the Denison and Woodbine sandstones overlying limestone aquifers like the Trinity Aquifer. These carbonate and evaporitic rock layers, formed 100–145 million years ago, contribute dissolved minerals to the supply. The geology promotes moderate buffering capacity and elevated mineral content, with surface runoff through clay-rich soils adding minor organic influences, yielding a moderately mineralised supply.

Moderately hard water in Hurst leads to moderate scale buildup in appliances like water heaters, dishwashers, and coffee makers, reducing efficiency and increasing energy costs by 20–30%. Laundry may feel stiffer, and soap lathering is less effective, often requiring more detergent. Annual descaling of fixtures and heaters is advised; a water softener is recommended for households with aesthetic concerns or sensitive equipment. pH typically ranges 7.0–8.5, chloramines are used for disinfection, and lead levels are well below the 15 ppb action level per monitoring data.
