Crowley Water Hardness & Quality Report (2026)

The Crowley Water System, operated by Louisiana Water Company, supplies water to about 19,489 residents in Acadia Parish, Louisiana, primarily serving the city of Crowley. This utility draws its entire supply from groundwater sources within the Chicot Aquifer, a part of the Mississippi River Alluvial Aquifer system located in the Mississippi Embayment region. Recharge for these surficial aquifers comes from local precipitation and infiltration from nearby rivers. While specific treatment plant names weren't detailed, the Louisiana Water Company can be reached for more information.

Geologically, the Crowley water originates from unconsolidated sedimentary deposits, including sands, gravels, clays, and silts, dating back to the Pleistocene and Holocene epochs. These layers are interbedded with limestone and other calcareous materials, remnants of ancient marine sediments. As groundwater filters through these carbonate-rich strata, it dissolves minerals like calcium and magnesium, resulting in a moderately mineralized water supply. This geology differs from harder bedrock regions, but the presence of these dissolved minerals contributes to the water's overall chemistry.

Homeowners in areas with moderately hard water, like Crowley, might notice a gradual buildup of scale in appliances such as water heaters, coffee makers, and dishwashers, which can reduce their efficiency over time. You may also find that soap doesn't lather as readily, potentially leading to increased detergent use. To combat scale, consider descaling fixtures and appliances annually. If scale issues become persistent and you want to protect your plumbing and appliances, installing a water softener is often a good idea for this level of hardness. The 2024 Louisiana Department of Health Water Grade report indicated secondary water quality issues but confirmed the system meets primary health standards.
