How Old Is Wilburton's Housing Stock?
With 61% 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
For residents trying to assess tap water risk in Wilburton, the median build year of 1989 is the starting context. It signals that a majority of homes were constructed before 1986 — the year federal rules prohibited lead solder in new plumbing — and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.
Over half of homes in Wilburton were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Wilburton: Remediation Cost in Perspective
Looking at how documented remediation costs fit within Wilburton's property market, the equity share lands in the elevated tier — a result that positions the household financial perspective as one requiring structured preparation, where mapping costs against household budget, documenting scope early, and sequencing by urgency are the practical tools that distinguish manageable outcomes from financially disruptive ones.
At 2.5% of home value, remediation costs in Wilburton represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,500–$4,000. Home values here are 35% below the Oklahoma average.
Protecting Children from Lead in Wilburton
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 61% of the Wilburton inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.
