What Makes Rosenberg's Water Unique?
Local geology and source profile
Rosenberg, Texas, in Fort Bend County — a major southwest Fort Bend County city (Rosenberg is one of the older established cities in the Houston southwest suburban corridor — a historic railroad and agricultural city in Fort Bend County that has experienced significant growth as part of the greater Houston metro expansion), adjacent to Richmond (the Fort Bend County seat) in the Fort Bend–Richmond–Rosenberg city pair on the Brazos River corridor, a diverse Fort Bend County community with a significant Hispanic-American, African-American, and Vietnamese-American population, and a major logistics and distribution city in the southwest Houston corridor — draws its municipal water supply from the Chicot Aquifer via the City of Rosenberg Water Division. Water hardness in Rosenberg measures 70.5 mg/L — classified as moderately soft.
Rosenberg's moderate softness — softer than neighboring Mission Bend (173 mg/L) — reflects the City of Rosenberg's effective treatment of the Gulf Coast Chicot Aquifer. The Chicot Aquifer at Rosenberg–Fort Bend County draws from the Holocene–Pleistocene Beaumont Formation (calcareous-moderate coastal plain clay and sand). City of Rosenberg applies more effective treatment than some neighboring Fort Bend County water districts, producing the moderate 70.5 mg/L.
With hardness at 70.5 mg/L, Rosenberg residents enjoy moderately soft water. City of Rosenberg Water Division consistently delivers water meeting all Texas TCEQ and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Gulf Coast Aquifer (Chicot Aquifer) via the City of Rosenberg Water Division — the Fort Bend County southwest Houston suburban Gulf Coastal Plain (Holocene–Pleistocene calcareous-moderate Gulf Coastal Plain alluvium and Chicot Aquifer sand; Fort Bend County west Gulf Coast supply; effective Rosenberg treatment); moderately soft supply at 70.5 mg/L in Fort Bend County.
