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.

While lead results averaged over Allendale ZIP codes come in under 10 micrograms per liter, that figure combines many 90th-percentile values and cannot describe one building, including the 25% of housing that predates 1986.
