Randolph: Lead Risk & Vulnerable Populations

0.0013
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.

Available area-level lead records for Randolph do not determine the lead level at an individual tap. Testing is the only way to confirm your water's lead content.
