Roscoe's drinking water received a grade of D+ (50.7 out of 100), indicating poor water quality. The city's 1 water system serves approximately 1,238 residents using groundwater.

Lead levels were measured at 0.0 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 139 violations on record, including 71 health-based violations. 36 remain unresolved.

Roscoe ranks #766 out of 1067 cities in Texas for water quality, placing it below average in the state. Roscoe 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, Roscoe may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities. The system has seen 16 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

04Where Roscoe's water comes from

Roscoe'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

1 system

1 water system, operated under local government ownership.

Delivery

1,238 people

Residents served across Roscoe'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 1,238 people through 1 water system.
