Housing & Infrastructure in Wilkinson
With 74% 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
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Wilkinson's median build year of 1963 reflects a housing stock where these older materials are a pervasive feature — not a rare legacy — of the residential plumbing landscape.
Over half of homes in Wilkinson 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 Wilkinson Homeowners
Given current Wilkinson valuations, the remediation-to-property-value ratio is low — most homeowners are looking at a proportionally modest share that fits within routine financial planning.
Remediation costs in Wilkinson are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 53% above the Indiana average.
Lead Exposure Risk for Children in Wilkinson
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 74% pre-rule share in Wilkinson keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
