Housing Age Profile
A median build year of 1991 in Clarkrange points to a housing stock where post-1986 construction is the norm. That matters because lead solder in plumbing — banned federally in 1986 — is a primary pathway by which older homes can elevate tap water lead above what enters the distribution system.
Most homes in Clarkrange were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Clarkrange
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.
Pre-rule stock in Clarkrange accounts for 29% of the inventory — a modest fraction — and citywide samples land safely beneath the federal action mark.
