Protecting Children from Lead in Marseilles
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.
EPA advises using only cold water for drinking and cooking, a basic precaution for Marseilles households, where the ZIP-code mean of utilities' 90th-percentile lead values tops 0.015 mg/L and 65% of housing predates 1986.
1 ZIP code (100% of the city's ZIP records) is served by a water system whose 90th-percentile lead result exceeds the EPA action level of 0.015 mg/L.
