Greenville: Lead Risk & Vulnerable Populations
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.
A tap test is the direct way to learn the lead level in a given Greenville home; 22% of local housing predates 1986.
