Understanding Pointe Coupee Parish’s Water

Drinking Water Quality Overview

EPA SDWIS

Pointe Coupee Parish's water systems carry a failing grade, scoring 40.0 out of 100. Over the past five years, EPA SDWIS records 10 health-based violations — a pattern that public water utilities are required to disclose and correct.

Watershed Conditions

EPA ATTAINS

Under the Clean Water Act §303(d), EPA ATTAINS tracks whether waterways meet quality standards for drinking, recreation, and aquatic life (reporting cycle: 2022). A large majority — 85.7% — of assessed waterways are impaired (66 of 77 water bodies) across Pointe Coupee Parish's watersheds. The leading impairment causes are dissolved oxygen and fecal coliform. Impairment does not mean tap water is unsafe — it measures ambient waterway conditions upstream of treatment, not finished drinking water.

Monitoring Network

EPA WQP

EPA's Water Quality Portal (WQP) aggregates monitoring data from federal, state, and tribal agencies. Pointe Coupee Parish has moderate coverage with 32 active monitoring sites with 29,353 recent measurements on record. Predominant monitoring categories include organics, pesticide and physical. More monitoring sites generally indicate greater scientific attention to local water conditions — and provide the baseline data that regulators use to set future impairment listings.
