Housing & Infrastructure in Delevan
With 60% 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
The lead that enters tap water in older homes often comes not from the municipal supply but from the home's own plumbing — from solder used in copper joints before the 1986 federal ban, or from lead pipes installed before 1970. In Delevan, where the median build year is 1988, these older materials are widespread. More than half the residential stock predates the 1986 solder ban, and a significant fraction predates 1970 as well. For residents in those homes, the city-wide water quality picture is a less relevant frame than the specific materials inside their own walls and under their own street.
Over half of homes in Delevan 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 Delevan Homeowners
The household financial perspective in Delevan reflects a moderate cost-to-value ratio — an equity share that is not trivially small but remains within the range where most homeowners can address documented water and safety issues by treating the expense as a real line item in property planning rather than a discretionary one.
Remediation costs are moderate relative to home values in Delevan. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 71% below the New York average.
Lead Exposure Risk for Children in Delevan
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.
Households with kids in the home — for whom CDC guidance places particular weight on minimizing exposure — face a specific local picture in Delevan. 60% of homes here come from the pre-rule era, and aggregate utility samples either approach or cross 0.015 mg/L. A baseline draw-test kit and certified lead-removal filtration are available via retailer networks for households confirming conditions at a specific tap.
