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.
If aggregate samples sit below the EPA action level and just 21% of North Sioux City's inventory comes from the pre-rule era, systemic lead is not a dominant local concern. The aggregate still cannot tell a homeowner what is actually flowing from a specific faucet on a specific morning, which is why an in-home draw exists as a separate measurement at the household tier.
