See the risk factors ↓Geneva's drinking water received a grade of A+ (96.8 out of 100), indicating excellent water quality. The city's 1 water system serves approximately 2,217 residents using groundwater.
Lead levels were measured at 1.5 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 1 health-based violation. All violations have been resolved.
Geneva ranks #3 out of 196 cities in Nebraska for water quality, placing it one of the best in the state. Geneva 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, Geneva may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.
02What's in Geneva's water
Every contaminant flagged in Geneva, on one shared scale: distance to its own legal limit. The red line is the limit — anything past it is out of compliance, and the closer a bar gets, the less headroom the system has.

03Geneva'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 1 health-based violation. All violations have been resolved.
All ten of the last ten years were clean — no EPA violations recorded for Geneva.
▲ Up 0.40 ppb since 2004. Latest reading: 1.5 ppb (2024) — 10% of the action level. Sampled at higher-risk homes (90th percentile).
04Where Geneva's water comes from
Geneva'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.
2,217 people
Residents served across Geneva'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 2,217 people through 1 water system.

05Pressure on Geneva'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 0 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
4 federal disaster declarations on record for Fillmore County. Flooding and severe storms can overwhelm treatment plants, cause sewage overflows, and push runoff into supplies.

What health violations has Geneva's water system had?
Geneva has 1 health-based violation on record. The most recent violation was recorded in October 2000. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. All health violations have been resolved.
Is Geneva's groundwater at risk of contamination?
Geneva uses groundwater, which can be affected by naturally occurring contaminants like arsenic, radon, and nitrate, as well as agricultural runoff and industrial activity. The system has 2 violations on record that may relate to groundwater quality. Groundwater systems are generally less susceptible to surface contamination but should be monitored for emerging contaminants like PFAS.
How does Geneva's water compare to other cities?
Geneva ranks #3 out of 196 cities in Nebraska (better than 98% of state cities) and #145 out of 15382 cities nationally (99th percentile). The grade of A+ reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
Does Geneva's small water system affect quality?
Geneva's system serves approximately 2,217 residents. Small community water systems (under 3,300 people) may have fewer financial resources for infrastructure upgrades and advanced treatment technologies. However, they are held to the same EPA drinking water standards as larger systems. This system has 2 violations on record.
