Housing Age Profile
Reading the housing data for Mount Lemmon, 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.
A significant portion of Mount Lemmon's housing stock predates 1970, when lead pipes were commonly used. Residents in older homes should consider water testing.

Protecting Children from Lead in Mount Lemmon
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 46% of local housing was built before solder rules changed - as is the case in Mount Lemmon - a faucet-level sample closes the gap that aggregate utility data cannot.
