Protecting Children from Lead in Afton
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.
In Afton, the average of the 90th-percentile lead results reported for its ZIP codes is at least 0.010 mg/L, the concentration EPA's 2024 rule sets as the lead action level for each water system's own 90th-percentile result starting in November 2027, not for an area average. No single system's compliance follows from this figure, and 100% of local homes predate 1986.
