01The verdict: is Convent water safe?

Convent's drinking water has significant quality concerns based on EPA testing data. With a grade of B+ (80.8/100), the system has issues across multiple categories. A water filter is recommended for all residents. The city's 2 water systems serve approximately 14,713 residents using surface water (rivers, lakes, or reservoirs).

The concern

10 unresolved violations on record

EPA records show open compliance items for this system. Most are administrative, but unresolved items are worth watching.

The good news

Lead is well under the limit

90th-percentile lead is 5.0 ppb — beneath the 15 ppb federal action level and under the 5 ppb watch threshold.

Keep watching

lithium is approaching its limit

Measured at 11.0000 µg/L — 120% of the 0.004 µg/L limit. Within the rules, but with less headroom than you'd want.

See the ledger ↓

Convent's drinking water received a grade of B+ (80.8 out of 100), indicating good water quality. The city's 2 water systems serve approximately 14,713 residents using surface water.

Lead levels were measured at 5.0 ppb (90th percentile), well within EPA limits. UCMR 5 testing detected 2 PFAS compounds in the water supply. The system has 71 violations on record, including 30 health-based violations. 10 remain unresolved.

Convent ranks #99 out of 309 cities in Louisiana for water quality, placing it mid-range in the state. The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection. PFAS compounds were detected in testing, though levels remain within current EPA limits. Residents seeking extra precaution may consider an activated carbon or reverse osmosis filter. Hexavalent chromium (chromium-6) was detected at 0.13 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.

05Pressure on Convent's watershed

Outside forces that shape what reaches the treatment plant. None of these is a verdict on the tap by itself — but each adds pressure worth knowing about.

Industrial discharge

Moderate — reported releases upstream

5 facilities within 10 miles reported 1,562k lb released to surface water in the latest EPA Toxics Release Inventory. Proximity doesn't equal tap contamination — treatment and hydrology decide — but it's pressure on the watershed.
