Lead Exposure Risk for Children in Orondo
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.
Whenever aggregate samples pass the federal action benchmark and pre-rule housing — 29% in Orondo — represents a smaller fraction, lead occupies a lower priority on the local picture.
