Protecting Children from Lead in Gray Summit
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Even though compliance with the federal lead action level is judged on each system's own 90th percentile, the average of those results across Gray Summit ZIP codes, 0.010 mg/L or more, is a reason to check at home, particularly in the 72% of housing built before 1986.
