How Old Is Grandfield's Housing Stock?
With 72% 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
Federal plumbing rules changed in two stages — lead pipes were phased out before 1970, and lead solder was banned in 1986 — but in Grandfield, where the median build year is 1961, most of the housing was already in place before those rules took effect. The materials installed under older standards remain embedded in a substantial portion of the residential inventory today.
Over half of homes in Grandfield were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Grandfield: Remediation Cost in Perspective
Although the Grandfield remediation share is moderate, it remains reachable for most homeowners who plan for the expense in advance.
Remediation costs are moderate relative to home values in Grandfield. The estimated $300–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 61% below the Oklahoma average.
Protecting Children from Lead in Grandfield
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.
Wherever 72% of local housing was built before solder rules changed — as is the case in Grandfield — a faucet-level sample closes the gap that aggregate utility data cannot.
