How Old Is Mountainburg's Housing Stock?
With 48% 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
Reading the housing data for Mountainburg, with a median build year of 1981, reveals a community where neither old nor new construction dominates. That balanced profile means lead-solder-era plumbing is present throughout a meaningful portion of the residential inventory — with risk concentrated in properties built before 1986 and most acute in those that predate 1970.
Most homes in Mountainburg were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Protecting Children from Lead in Mountainburg
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 48% of local housing was built before solder rules changed — as is the case in Mountainburg — a faucet-level sample closes the gap that aggregate utility data cannot.
