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 Grenloch, where the median build year is 1903, 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.

Grenloch: Lead Risk & Vulnerable Populations

77%
Homes Built Before 1986

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 77% of local housing was built before solder rules changed — as is the case in Grenloch — a faucet-level sample closes the gap that aggregate utility data cannot.
