How Old Is Duke's Housing Stock?
With 77% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
The character of Duke's housing stock is one of deep historical layering - a median build year of 1978 signals a city built largely before the plumbing era changes of 1986 and 1970. Lead-soldered copper joints and, in the oldest properties, lead service lines are commonly present in this inventory. That context shapes what individual water testing may reveal, particularly in neighborhoods where the oldest housing is concentrated.
Over half of homes in Duke were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Duke: Remediation Cost in Perspective
For most homeowners in Duke, the estimated cost of water and safety remediation represents a proportionally modest share of what properties are worth - placing this area in the lower tier of the remediation share scale.
Remediation costs in Duke are relatively low compared to home values. The $300–$1,500 estimated range is a small fraction of median property value. Home values are 24% below the Oklahoma average.
Protecting Children from Lead in Duke
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.
Despite citywide averages serving as the standard public reference point, those aggregates cannot resolve what is happening at one specific faucet - and where 77% of Duke homes come from before the solder rule or where utility samples sit at or above the action mark, the gap between system data and faucet reality matters more than it does in lower-exposure communities. An in-home draw closes that gap, with certified filtration through retailer networks available where confirmed faucet results warrant additional measures.
