Housing & Infrastructure in Ixonia
With 43% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
Tap water lead levels are shaped by two factors: what the utility delivers, and what the household plumbing adds to it. Older homes contribute disproportionately to that second variable because lead solder was standard in copper plumbing before 1986, and lead pipes were common before 1970. In Ixonia, where the median build year is 1990, a substantial share of the housing stock falls into these older categories. The bar chart above breaks out the pre-1970, 1970-to-1986, and post-1986 segments — the key ages for understanding where plumbing-era risk concentrates across the city.
Most homes in Ixonia were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Ixonia Homeowners
Remediation costs in Ixonia are small relative to typical property values — the cost-to-value ratio here is favorable.
Remediation costs in Ixonia are relatively low compared to home values. The $2,000–$4,000 estimated range is a small fraction of median property value. Home values are 50% above the Wisconsin average.
Lead Exposure Risk for Children in Ixonia
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Practically, the structural drivers in Ixonia — 43% pre-rule stock and citywide monitoring at or beyond the regulatory benchmark — make an in-home draw the practical way to translate aggregate averages into the specific conditions at one address.

Flood & Climate Risk in Ixonia
Flood activity in Ixonia is neither negligible nor at the level of the highest-exposure areas in the NFIP dataset. The 1-claim record and 100% flood zone coverage suggest a community that has experienced recurrent events but has not faced the kind of sustained, severe exposure where water-supply contamination becomes a primary public health concern. It sits in a middle range where flood history merits inclusion in any complete local water quality picture.
Ixonia has a moderate flood history with 1 FEMA claims. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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. Flood damage can add significantly to the estimated <strong>$3,000</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
