Fowler's drinking water received a grade of B (76.1 out of 100), indicating good water quality. The city's 1 water system serves approximately 1,169 residents using ground water under influence.

Lead levels were measured at 3.0 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 46 violations on record, including 25 health-based violations. 4 remain unresolved.

Fowler ranks #96 out of 244 cities in Colorado for water quality, placing it mid-range in the state. Fowler 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, Fowler may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities. The system has seen 8 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

04Where Fowler's water comes from

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

Source

Ground Water Under Influence

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

1 system

1 water system, operated under local government ownership.

Delivery

1,169 people

Residents served across Fowler'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 1,169 people through 1 water system.
