Saint Thomas: Lead Risk & Vulnerable Populations

70%
Homes Built Before 1986
0.0086
mg/L Avg Lead (Limit: 0.015)

Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.

Confirming what arrives at a specific faucet is something utility-side averages cannot do. With 70% of Saint Thomas stock built before the lead-solder ban and citywide monitoring at or beyond the regulatory mark, a tap-level kit fits the standard diligence picture.
