Lead Exposure Risk for Children in Williamston
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.
Households with young children in Williamston have two area numbers to weigh. One is the mean of 90th-percentile lead values reported for local ZIP codes, which is at or above 0.010 mg/L; the other is the 45% share of housing that dates from before 1986. Neither describes one home, and sending a tap sample to an accredited laboratory is how a family measures its own lead level.

Historical NFIP Claim Context in Williamston

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies.
