What Makes Moss Bluff's Water Unique?
Local geology and source profile
Moss Bluff, Louisiana, in Calcasieu County — a Calcasieu County census-designated place adjacent to Lake Charles and DeQuincy in southwest Louisiana — receives its water from the Calcasieu Parish Water or City of Lake Charles Water, drawing from the Calcasieu River through the southwest Louisiana distribution.
The hard 153 mg/L hardness and TDS of 390.1 mg/L reflect the Calcasieu County Coastal Plain supply's hard calcareous character — the Quaternary Gulf Coastal Plain alluvium and Tertiary Midway Group marine sediments both contribute dissolved calcium, magnesium, and sulfate minerals to the southwest Louisiana water supply (compare Lake Charles LA: 150/382 in Calcasieu County comparable; DeQuincy LA: 156/398 in Calcasieu County comparable; Moss Bluff consistent hard from the same Calcasieu County Calcasieu River Gulf Coastal Plain supply). The Calcasieu watershed — Quaternary Gulf Coastal Plain alluvium (calcareous — primary hardness contributor), Tertiary Midway Group (slightly calcareous — secondary contributor), and Holocene Calcasieu River alluvium (calcareous — TDS contributor).
At 153 mg/L with TDS 390, Moss Bluff's water is hard — scale builds in appliances and fixtures. Quarterly descaling is appropriate. The PFAS level of 13.1 ppt is very high — a certified drinking water filter with PFAS removal is strongly recommended — Calcasieu Parish is home to one of the largest petrochemical industrial corridors in the US (Lake Charles chemical plants, refineries) which are primary contributors to Moss Bluff's very high PFAS readings.
Geology & Source: Moss Bluff in Calcasieu County draws from the Calcasieu Parish Water on the Calcasieu River (Calcasieu County, southwest Louisiana) — the Calcasieu watershed at Calcasieu County drains Quaternary Gulf Coastal Plain alluvium (calcareous) and Tertiary Midway Group (slightly calcareous) — Louisiana Calcasieu County Calcasieu River Gulf Coastal Plain supply produces hard water at 153 mg/L with TDS 390.1 mg/L.
