Enterprise's drinking water received a grade of B (79.6 out of 100), indicating good water quality. The city's 2 water systems serve approximately 1,402 residents using groundwater.

Lead levels were measured at 0.5 ppb (90th percentile), well within EPA limits. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 158 violations on record, including 6 health-based violations. 8 remain unresolved.

Enterprise ranks #103 out of 319 cities in Mississippi for water quality, placing it mid-range in the state. Enterprise 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. As a small community water system, Enterprise may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities. The system has seen 9 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

04Where Enterprise's water comes from

Enterprise'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

2 systems

2 water systems, operated under local government ownership.

Delivery

1,402 people

Residents served across Enterprise'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 1,402 people through 2 water systems.
