mg/L average of reported water-system 90th-percentile lead results (the 0.015 action level applies to each system's result, not to this average)

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 Cassopolis ZIP codes, 0.010 mg/L or more, is a reason to check at home, particularly in the 61% of housing built before 1986.
