Housing Age Profile
For residents trying to assess tap water risk in Kellnersville, the median build year of 1955 is the starting context. It signals that a majority of homes were constructed before 1986 — the year federal rules prohibited lead solder in new plumbing — and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.
Over half of homes in Kellnersville were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

At 4.3% of home value, remediation costs in Kellnersville represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $3,910–$8,920. Home values here are 36% below the Wisconsin average.
Lead Exposure Risk for Children in Kellnersville
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.
Confirming what arrives at a household tap is the practical question that utility-side averages cannot answer for one specific address. In Kellnersville, where 94% of housing predates the solder ban and citywide samples sit beyond the action level, a household kit and certified filtration are the household-level tools.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.
