01The verdict: is Amherst water safe?
Amherst's tap water meets most EPA standards but has areas that warrant attention. With a grade of B+ (81.5/100), some contaminant levels or compliance issues suggest that residents may benefit from additional filtration. The city's 1 water system serves approximately 2,231 residents using surface water (rivers, lakes, or reservoirs).
1 unresolved violation on record
EPA records show an open compliance item for this system. Most are administrative, but unresolved items are worth watching.

Recent compliance history is the best predictor of future problems — the year-by-year record is below.
See the record ↓Amherst's drinking water received a grade of B+ (81.5 out of 100), indicating good water quality. The city's 1 water system serves approximately 2,231 residents using surface water.
Lead levels were measured at 0.7 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 60 violations on record, including 8 health-based violations. 1 remains unresolved.
Amherst ranks #139 out of 229 cities in Virginia for water quality, placing it below average in the state. The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection. As a small community water system, Amherst may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

03Amherst'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 60 violations on record, including 8 health-based violations. 1 remains unresolved.
6 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 0.26 ppb since 1993. Latest reading: 0.74 ppb (2025) — 5% of the action level. Sampled at higher-risk homes (90th percentile).
04Where Amherst's water comes from
Amherst's drinking water comes primarily from surface water sources such as rivers, lakes, or reservoirs.
Surface Water
Rivers, lakes, or reservoirs — more exposed to runoff, agriculture, and seasonal swings than groundwater.
Local treatment
Multi-barrier treatment: coagulation, sedimentation, filtration, and disinfection to meet EPA standards.
1 system
1 water system, operated under local government ownership.
2,231 people
Residents served across Amherst's service area.
Surface water systems require multi-stage treatment including coagulation, sedimentation, filtration, and disinfection to meet EPA Safe Drinking Water Act standards. These sources can be impacted by seasonal changes, stormwater runoff, upstream agriculture, and industrial discharge. The system is operated by local government ownership and serves approximately 2,231 people through 1 water system.

As a surface-water system, these water bodies may directly influence Amherst's drinking water supply.
05Pressure on Amherst'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.
Industrial discharge
2 facilities within 10 miles reported 2k lb released to surface water in the latest EPA Toxics Release Inventory. Proximity doesn't equal tap contamination — treatment and hydrology decide — but it's pressure on the watershed.
Flood & storm history
8 federal disaster declarations on record for Amherst County. Flooding and severe storms can overwhelm treatment plants, cause sewage overflows, and push runoff into supplies.
Superfund proximity
1 National Priorities List site within 10 miles. Proximity does not necessarily indicate tap-water contamination — the connection depends on hydrology and treatment.
Drought
Amherst County is in D3 (extreme 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.
