Housing Age Profile
What does a median build year of 1961 mean for water safety in Duncan? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used - making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in Duncan 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 Duncan Homeowners
At current valuations, Duncan falls in the moderate remediation-share tier - a level where treating this as a budgeted line item rather than an ad-hoc expense is the practical approach.
Remediation costs are moderate relative to home values in Duncan. The estimated $950–$2,100 range is manageable for most homeowners but still worth budgeting for. Home values are 17% below the Nebraska average.
Lead Exposure Risk for Children in Duncan
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 78% of the Duncan inventory was built in that earlier era - a share large enough to move household-level reads onto the standard list.
