Housing Age Profile
Reading the housing data for Maryville, with a median build year of 1996, 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 Maryville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Locally, 37% of Maryville homes carry interior plumbing from the era when lead solder was still permitted in new builds, and citywide monitoring approaches or crosses the EPA action benchmark. Households can find a draw-test kit and certified filtration through verified retailers.
