Key Contaminants Detected in Lake Geneva
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Lake Geneva's Housing Stock?
With 60% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Renovation history matters as much as age: in Lake Geneva, with a median build year of 1974, some older homes have been replumbed and some have not.
Over half of homes in Lake Geneva were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.
Source: U.S. Census Bureau ACS B25034.
Lake Geneva: Remediation Cost in Perspective
Neither the low nor the elevated band applies to Lake Geneva; its estimated remediation cost sits between those two cutoffs relative to home prices.
Estimated remediation costs in Lake Geneva can be compared with local home values. The estimated $3,000–$7,100 range is a planning estimate; get a property-specific quote and check it against your budget. Home values are 46% above the Wisconsin average.
Protecting Children from Lead in Lake Geneva
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
A citywide figure cannot tell a family in Lake Geneva what its own faucet delivers. Here, averaging each ZIP code's 90th-percentile lead value gives more than 15 micrograms per liter, and pre-1986 homes account for 60% of the housing.
1 ZIP code (100% of the city's ZIP records) is served by a water system whose 90th-percentile lead result exceeds the EPA action level of 0.015 mg/L.

Historical Flood-Claim Evidence for Lake Geneva
Historical NFIP data for Lake Geneva contains 13 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $9,141. Among ZIP codes with claim records, 0% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. The $4,700 remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.

What You Can Do in Lake Geneva
- Test your water at home. City-level data shows averages - your tap may differ. Consider testing your home's tap water for lead, since household plumbing can affect its level.
- Install a certified water filter. For Lead and Copper Rule, listed in the water-quality records for Lake Geneva: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it. Not every contaminant has a consumer filter certification.
- Check your home's plumbing. With 60% of homes built before 1986, lead solder is a real possibility.
- Review your water system's CCR. If you use a community water system, request its annual Consumer Confidence Report for system-level test results or find it online.
