Lead Exposure Risk for Children in Ellsworth Afb
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.
Once federal rules removed lead-bearing solder from new plumbing, building practice changed quickly. Ellsworth Afb now carries just 8% of older inventory from that earlier era. Citywide readings remain compliant, though no system-level number can replace a one-home draw.
