Housing & Infrastructure in Sumner
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. Sumner's median build year of 1967 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 Sumner 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 Sumner Homeowners
Across Sumner, the equity share taken up by estimated remediation is small — a favorable ratio for most property owners.
Remediation costs in Sumner are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 40% below the Nebraska average.
Lead Exposure Risk for Children in Sumner
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 Sumner keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
