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.

98% of Mar Lin homes were constructed before 1986, when federal law began limiting lead in pipes, solder and flux. Across the city's ZIP codes, water systems' 90th-percentile lead results average no less than 0.010 mg/L. That average can mix higher and lower systems, so it neither confirms nor rules out a problem at a single address; asking the utility how the home's service line is classified in its inventory is a practical next step.
