What Makes La Porte's Water Unique?
Local geology and source profile
La Porte, Texas, in Harris County — a major southeast Houston industrial and residential community on Galveston Bay (La Porte is on the shoreline of Galveston Bay and San Jacinto Bay — a major southeast Houston petrochemical and industrial community adjacent to the Houston Ship Channel), home of the San Jacinto Battleground State Historic Site (the site of the decisive Battle of San Jacinto on April 21, 1836, where Sam Houston's Texas army defeated Mexican General Santa Anna, winning Texas independence in a stunning 18-minute battle — one of the most decisive battles in North American history), adjacent to the Houston Ship Channel (one of the most heavily industrialized waterways in the United States — the primary petrochemical corridor of the Texas Gulf Coast), and a diverse Harris County community — draws its municipal water supply from the Trinity River via the Trinity River Authority. Water hardness in La Porte measures 190 mg/L — classified as hard.
La Porte's hard supply reflects the southeast Harris County Gulf Coast Beaumont Formation geology and Trinity River characteristics. The Trinity River (Lake Livingston) drains the east Texas Gulf Coastal Plain (Pleistocene Beaumont and Montgomery Formations — calcareous-moderate coastal plain clay and sand) and the east Texas Piney Woods calcareous-moderate terrain. Trinity River Authority treatment and distribution to La Porte produces the hard 190 mg/L.
At 190 mg/L, La Porte residents face regular hard water challenges. Monthly descaling with citric acid solution is recommended. City of La Porte Water Division consistently delivers water meeting all Texas TCEQ and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Trinity River (Lake Livingston) via the City of La Porte Water Division (Trinity River Authority) — the Harris County southeast Houston Gulf Coastal Plain (Holocene–Pleistocene calcareous-moderate Gulf Coastal Plain Beaumont Formation and Trinity River alluvial supply with treatment; southeast Harris County La Porte distribution zone); hard supply at 190 mg/L in Harris County.
