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.

Wherever 40% of local housing was built before solder rules changed — as is the case in Nathrop — a faucet-level sample closes the gap that aggregate utility data cannot.
