Broussard Water Hardness & Quality Report (2026)

Broussard, Louisiana, in Lafayette Parish — a Lafayette Parish city adjacent to Lafayette and Youngsville in south-central Louisiana's Cajun Country — receives its water from the City of Broussard Water Department or Lafayette Utilities System, drawing from the Vermilion River watershed through the south-central Louisiana distribution.

The moderately hard 127 mg/L hardness and TDS of 294.6 mg/L reflect the Lafayette Parish Vermilion River supply's moderate Coastal Plain character — the Quaternary coastal plain alluvium contains calcareous shell beds from the south Louisiana depositional environment, and the Holocene Gulf Coastal sediment contributes dissolved mineral content from its marine carbonate heritage (compare Lafayette LA: 124/287 in Lafayette Parish comparable; Youngsville LA: 129/301 in Lafayette Parish comparable; Broussard consistent moderate from the same Lafayette Parish Vermilion River Quaternary alluvial supply). The Vermilion River watershed — Quaternary coastal plain alluvium (slightly calcareous — primary hardness contributor), Holocene Gulf Coastal sediment (calcareous — secondary contributor), and Holocene Vermilion River alluvium (slightly calcareous — minor TDS).

At 127 mg/L with TDS 295, Broussard's water is moderately hard — mild scale buildup. Semi-annual descaling is appropriate. The PFAS level of 11.4 ppt is very high — a certified filter with PFAS removal is strongly recommended — the Lafayette Parish south Louisiana petrochemical and military (NAS JRB Fort Worth area legacy) corridor contributes to Broussard's very elevated PFAS readings.
