Housing & Infrastructure in Wenona
With 81% 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
When a city's housing median build year is 1958, as in Wenona, the implication for water quality research is straightforward: municipal-level data captures what leaves the treatment plant, but household plumbing from before 1986 determines what actually arrives at the tap. In cities where older housing predominates, that gap between system-level and household-level data is widest.
Over half of homes in Wenona were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Wenona Homeowners
The equity impact of remediation in Wenona sits at a moderate level — real enough to plan for, within reach for most.
Remediation costs are moderate relative to home values in Wenona. The estimated $950–$2,100 range is manageable for most homeowners but still worth budgeting for. Home values are 31% below the Illinois average.
Lead Exposure Risk for Children in Wenona
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 81% pre-rule share in Wenona keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

What You Can Do in Wenona

- Check your home's plumbing. With 81% of homes built before 1986, lead solder is a real possibility.
