01The verdict: is Breaux Bridge water safe?

Breaux Bridge's drinking water has significant quality concerns based on EPA testing data. With a grade of D (45.5/100), the system has issues across multiple categories. A water filter is recommended for all residents. The city's 3 water systems serve approximately 13,980 residents using groundwater (wells).

The concern

Copper is over its legal limit

Measured at 1.50 mg/L against the EPA Action Level of 1.3 mg/L. The ledger below shows how far over — and which filter removes it.

The good news

Lead is well under the limit

90th-percentile lead is 4.6 ppb — beneath the 15 ppb federal action level and under the 5 ppb watch threshold.

lithium is approaching its limit

Measured at 46.2000 µg/L — 120% of the 0.004 µg/L limit. Within the rules, but with less headroom than you'd want.

See the ledger ↓

Breaux Bridge's drinking water received a grade of D (45.5 out of 100), indicating poor water quality. The city's 3 water systems serve approximately 13,980 residents using groundwater.

Lead levels were measured at 4.6 ppb (90th percentile), well within EPA limits. UCMR 5 testing detected 1 PFAS compound in the water supply. The system has 60 violations on record, including 34 health-based violations. 31 remain unresolved.

Breaux Bridge ranks #237 out of 309 cities in Louisiana for water quality, placing it among the lowest-rated in the state. Breaux Bridge relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff. 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. The system has seen 12 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

04Where Breaux Bridge's water comes from

Breaux Bridge's drinking water is drawn from underground aquifers through wells.

Source

Groundwater

Underground aquifers reached by wells — naturally filtered, but can carry minerals like arsenic and nitrate.

Treatment

Local treatment

Groundwater generally needs less treatment — typically disinfection and, where needed, mineral removal.

Distribution

3 systems

3 water systems (1 wholesaler), operated under local government ownership.

Delivery

13,980 people

Residents served across Breaux Bridge's service area.

Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals. Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds. The system is operated by local government ownership and serves approximately 13,980 people through 3 water systems.

05Pressure on Breaux Bridge'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

Present — monitored

5 facilities within 10 miles reported 119 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.
