*Exponentiated coefficient from logistic regression model with reported delinquency as dependent variable.

^†1,949 children in the dataset relying on private well water were matched to 1,949 with community-supplied water on race, biological sex, age at time of blood test, blood test year, year home was built, and home value quartile.
