Underhill: Lead Risk & Vulnerable Populations

0.0014
mg/L Avg Lead (Limit: 0.015)

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.

After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted - but 65% of the Underhill inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.
