Lead Exposure Risk for Children in Copperopolis

25%
Homes Built Before 1986
0.0018
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.

Since the federal solder ban took effect, new plumbing has been built without that pathway, and Copperopolis's pre-rule stock at 25% reflects a contained footprint.
