What Makes Texas City's Water Unique?
Local geology and source profile
Texas City, Texas, in Galveston County on Galveston Bay — a major Gulf Coast industrial city known for the 1947 Texas City Disaster (the deadliest industrial accident in US history — ammonium nitrate cargo ship explosions killed approximately 581 people and injured thousands), a major petrochemical and refining corridor adjacent to the Port of Texas City, and a diverse working-class community adjacent to Galveston Island — draws its municipal water supply from the Galveston Bay watershed via the City of Texas City Water Division and Gulf Coast Water Authority (GCWA). Water hardness in Texas City measures 342.5 mg/L — classified as very hard.
Texas City's very hard supply reflects the Texas Gulf Coast Galveston Bay watershed's concentrated calcareous geology. The GCWA supply drawing from Trinity River and Brazos River drains: the Texas Cretaceous calcareous formations (Cretaceous Austin Chalk, Eagle Ford Shale, and Taylor Marl — highly calcareous marine formations of the Texas Coastal Plain); the Gulf Coastal Plain calcareous Pleistocene marine terrace deposits (calcareous shell marl and coastal plain); and Galveston Bay estuarine concentration. The calcareous Texas Coastal Plain Cretaceous and Pleistocene marine terrain, combined with Gulf Coast evaporative concentration, produces the very hard 342.5 mg/L at Texas City.
At 342.5 mg/L, Texas City residents face severe hard water challenges. Scale deposits form very rapidly on all fixtures and appliances — weekly descaling and appliance protection measures are strongly recommended. City of Texas City Water Division consistently delivers water meeting all Texas TCEQ and EPA Safe Drinking Water Act requirements.
Geology & Source: Surface water from the Trinity River Authority (TRA) Galveston Bay watershed via the City of Texas City Water Division — the Galveston County Gulf Coast Texas Coastal Plain (Pleistocene–Holocene calcareous coastal deposits and Trinity River calcareous watershed); very hard supply at 342.5 mg/L — reflecting the Texas Gulf Coast calcareous coastal supply at Texas City.
