Sargent's drinking water received a grade of F (43 out of 100), indicating failing water quality. The city's 2 water systems serve approximately 3,328 residents using groundwater.

Lead levels were measured at 6.5 ppb (90th percentile), which is within EPA limits but above recommended levels. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 106 violations on record, including 76 health-based violations. 26 remain unresolved.

Sargent ranks #942 out of 1067 cities in Texas for water quality, placing it among the lowest-rated in the state. Sargent 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. While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection. The system has seen 57 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

Groundwater generally needs less treatment — typically disinfection and, where needed, mineral removal.

Distribution

2 systems

2 water systems (1 wholesaler), operated under local government ownership.

Delivery

3,328 people

Residents served across Sargent'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 3,328 people through 2 water systems.
