Connecticut has some of the strictest lead-screening laws in the country – requiring every child to be tested for exposure twice, once between ages 1 and 2, and a second time before they reach age 3. But gaps exist in testing and some children are never screened as required.
This chart shows the percentage of children in each town under the age of 6 who have been screened for lead in 2017.
