Lead Exposure Risk for Children in Decatur
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 Decatur do not determine the lead level at an individual tap. Testing is the only way to confirm your water's lead content.
