What Makes Farmers Branch's Water Unique?
Local geology and source profile
Farmers Branch, Texas, in Dallas County — a major north Dallas County suburban community (Farmers Branch is one of the first-ring north Dallas suburbs — a primarily residential and light industrial community in the north Dallas corridor, home of a significant corporate and commercial base including major call centers and corporate offices), a diverse Dallas County community with a significant Hispanic-American, South Asian-American, and corporate professional population, home of one of the most controversial municipal immigration enforcement attempts in the US (Farmers Branch attempted to ban renting to illegal immigrants in 2006 — a nationally publicized legal battle that resulted in the ordinance being struck down), and an inner-ring north Dallas suburb in the LBJ Freeway–I-35E corridor — draws its municipal water supply via the City of Farmers Branch Water Division. Water hardness in Farmers Branch measures 415.5 mg/L — classified as extremely hard.
Farmers Branch's extremely hard supply — one of the highest in the Dallas metro — reflects the north Texas Trinity River basin's highly calcareous Cretaceous geology combined with elevated TDS. The Dallas Water (Trinity River, Lake Lewisville) supply distributes to Farmers Branch, with the highly calcareous Austin Chalk and Eagle Ford Shale geology producing extremely mineralized water at 415.5 mg/L.
At 415.5 mg/L, Farmers Branch residents face severe hard water challenges. Water softeners and regular appliance descaling are essential. City of Farmers Branch Water Division consistently delivers water meeting all Texas TCEQ and EPA Safe Drinking Water Act requirements.
Geology & Source: Mixed supply from the Trinity River (Lake Lewisville) and Dallas Water via the City of Farmers Branch Water Division — the Dallas County north Texas north Dallas suburb Farmers Branch corridor (Cretaceous calcareous Austin Chalk and Eagle Ford Shale — the highly calcareous north Texas Cretaceous Coastal Plain chalky carbonate; Dallas area Trinity River supply with TDS very high); extremely hard supply at 415.5 mg/L in Dallas County.
