See the record ↓Trezevant's drinking water received a grade of A- (89.2 out of 100), indicating good water quality. The city's 1 water system serves approximately 955 residents using groundwater.
Lead levels were measured at 1.3 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 2 violations on record, including 0 health-based violations. 1 remains unresolved.
Trezevant ranks #95 out of 299 cities in Tennessee for water quality, placing it mid-range in the state. Trezevant 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, Trezevant may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

03Trezevant's ten-year track record
Each box is one year. A green check means no EPA violations; a numbered badge counts that year's violations — red if any were health-based, amber if they were monitoring or paperwork issues. The system has 2 violations on record, including 0 health-based violations. 1 remains unresolved.
9 of the last ten years were clean. The numbered years had EPA violations — red when any were health-based, amber when they were paperwork or missed-testing issues.
▼ Down 1.7 ppb since 1993. Latest reading: 1.3 ppb (2025) — 9% of the action level. Sampled at higher-risk homes (90th percentile).
04Where Trezevant's water comes from
Trezevant's drinking water is drawn from underground aquifers through wells.
Groundwater
Underground aquifers reached by wells — naturally filtered, but can carry minerals like arsenic and nitrate.
Local treatment
Groundwater generally needs less treatment — typically disinfection and, where needed, mineral removal.
1 system
1 water system, operated under local government ownership.
955 people
Residents served across Trezevant'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 955 people through 1 water system.

05Pressure on Trezevant'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.
Drought
Carroll County is in D1 (moderate drought) per the U.S. Drought Monitor (week of Jul 2026). Drought can raise disinfection-byproduct levels and taste/odor issues as utilities draw from lower reservoirs.
