waterverge.com West Bend, WI — Water Quality Report
West Bend's drinking water received a grade of F (34.1 out of 100), indicating failing water quality. The city's 5 water systems serve approximately 32,624 residents using groundwater.
Lead levels were measured at 7.2 ppb (90th percentile), which is within EPA limits but above recommended levels. UCMR 5 testing detected 2 PFAS compounds, with levels exceeding EPA maximum contaminant levels in the water supply.
The system has 172 violations on record, including 11 health-based violations. 31 remain unresolved.
What to know about West Bend's water
West Bend ranks #445 out of 446 cities in Wisconsin for water quality, placing it among the lowest-rated in the state.
West Bend 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.
Of particular concern: PFAS "forever chemical" levels exceed the 2024 EPA maximum contaminant levels. These synthetic compounds don't break down naturally and require specialized filtration such as reverse osmosis or granular activated carbon.
Hexavalent chromium (chromium-6) was detected at 0.27 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.
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 73 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

What West Bend residents can do
Recommended: Reverse osmosis system. This addresses the specific contaminants found in West Bend's water.
Your water utility is required to publish an annual Consumer Confidence Report (CCR) with detailed testing results. Ask for the latest copy or check your utility's website.
Run cold water for 30 seconds before drinking, especially in the morning. Lead and copper leach from household plumbing when water sits in pipes.
West Bend's area has a history of flooding. After severe weather, watch for boil water advisories from your local utility.

Water source & infrastructure
Where West Bend's water comes from
West Bend's drinking water is drawn from underground aquifers through wells.
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 32,624 people through 5 water systems.
