Eunice Water Hardness & Quality Report (2026)

Eunice, Louisiana, in Saint Landry Parish — a Saint Landry Parish city adjacent to Opelousas and Basile in the south-central Louisiana prairie — receives its water from the City of Eunice Water Department, drawing from the Chicot Aquifer through the south-central Louisiana distribution.

The hard 166.5 mg/L hardness and TDS of 444.7 mg/L reflect the Saint Landry Parish supply's hard Gulf Coastal Plain character — the Quaternary Chicot Aquifer and Pleistocene Prairie Formation are calcareous formations in the south Louisiana coastal prairie; the Chicot Aquifer at Saint Landry Parish concentrates moderate to hard dissolved mineral content from the Gulf Coastal Plain geological corridor (compare Opelousas LA: 162/434 in Saint Landry Parish comparable; Basile LA: 170/455 in Saint Landry Parish comparable; Eunice consistent hard from the same Saint Landry Parish Chicot Aquifer Quaternary calcareous supply). The Chicot Aquifer at Saint Landry Parish — Quaternary Chicot Aquifer (calcareous — primary hardness contributor), Pleistocene Prairie Formation (calcareous — secondary contributor), and Holocene Gulf Coastal Plain alluvium (calcareous — TDS contributor).

At 166.5 mg/L with TDS 445, Eunice's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 14.0 ppt is very high — a certified filter with PFAS removal is strongly recommended. Review the City of Eunice's annual water quality report.
