01The verdict: is Milton water safe?
Milton's drinking water has significant quality concerns based on EPA testing data. With a grade of F (43.2/100), the system has issues across multiple categories. A water filter is recommended for all residents. The city's 4 water systems serve approximately 13,362 residents using groundwater (wells).
102 unresolved violations on record
EPA records show open compliance items for this system. Most are administrative, but unresolved items are worth watching.
See what was cited ↓Lead is well under the limit
90th-percentile lead is 0.0 ppb — beneath the 15 ppb federal action level and under the 5 ppb watch threshold.
See the trend ↓lithium is approaching its limit
Measured at 12.2000 µg/L — 120% of the 0.004 µg/L limit. Within the rules, but with less headroom than you'd want.
See the ledger ↓Milton's drinking water received a grade of F (43.2 out of 100), indicating failing water quality. The city's 4 water systems serve approximately 13,362 residents using purchased ground water.
Lead levels were measured at 0.0 ppb (90th percentile), well within EPA limits. UCMR 5 testing detected 1 PFAS compound in the water supply. The system has 134 violations on record, including 40 health-based violations. 102 remain unresolved.
Milton ranks #259 out of 309 cities in Louisiana for water quality, placing it among the lowest-rated in the state. Milton purchases its water from a regional wholesaler, meaning quality depends on both the supplier's treatment and the local distribution system's condition. 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 63 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
02What's in Milton's water
Every contaminant flagged in Milton, on one shared scale: distance to its own legal limit. The red line is the limit — anything past it is out of compliance, and the closer a bar gets, the less headroom the system has.

04Where Milton's water comes from
Milton purchases its water supply from a regional wholesale provider rather than treating raw water directly.
Purchased Groundwater
Water is bought from a regional wholesaler; quality starts at the supplier's intake and treatment.
Wholesale supplier
Primary treatment happens at the wholesaler; the local utility maintains disinfectant residual in its pipes.
4 systems
4 water systems (1 wholesaler), operated under private ownership.
13,362 people
Residents served across Milton's service area.
Water quality depends on both the wholesaler's treatment standards and the condition of Milton's local distribution pipes and storage facilities. Purchased water systems are common in suburban areas and smaller communities that lack the infrastructure for independent treatment. The system is operated by private ownership and serves approximately 13,362 people through 4 water systems.

Water bodies near Milton
These water bodies shape the regional watershed and can indirectly affect groundwater quality.
05Pressure on Milton'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
5 facilities within 10 miles reported 0 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.
