Water comes from St John Water District 2
St John Water District 2 supplies Garyville: about 71% of residents live in its service area. About 29% of homes are outside any mapped community water system, most likely on private wells, which EPA doesn’t regulate. It draws surface water (EPA lists St John Water District 1 as seller) and serves 3,702 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 80% of the 5,012 systems serving 3,301–10,000 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2023–Dec 2025, was 0.0 ppb, below the 15 ppb action level that applied. The highest in five years was 2.0 ppb. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
