See the risk factors ↓Urbana's drinking water received a grade of A- (86.7 out of 100), indicating good water quality. The city's 1 water system serves approximately 1,554 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 1 violation on record, including 0 health-based violations. 1 remains unresolved.
Urbana ranks #312 out of 430 cities in Iowa for water quality, placing it below average in the state. Urbana 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, Urbana may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

04Where Urbana's water comes from
Urbana'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.
1,554 people
Residents served across Urbana'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 1,554 people through 1 water system.

Water bodies near Urbana
These water bodies shape the regional watershed and can indirectly affect groundwater quality.
05Pressure on Urbana'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
1 facility 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
9 federal disaster declarations on record for Benton County. Flooding and severe storms can overwhelm treatment plants, cause sewage overflows, and push runoff into supplies.
