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.

Before the federal solder ban, lead solder was a routine plumbing material, and 59% of the Wanamingo inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.
