Drinking water is one exposure route. These are the other federal datasets that cover ZIP 60416 and Grundy County, IL.

Radon risk in Grundy County, IL

The EPA places Grundy County, IL in Zone 1 - the EPA's highest-risk category, where the predicted average indoor radon level is above 4 pCi/L. Zone maps predict the radon potential of an area from geology and existing indoor readings - they do not describe any individual home. Radon is the leading cause of lung cancer among people who have never smoked, and the only way to know your own level is a test kit.

Lead paint risk in Grundy County, IL

Census figures show 42% of homes in Grundy County, IL were built before 1980, and 16% before 1950. Lead-based paint was banned for residential use in 1978, so older housing stock is the strongest available proxy for lead-paint exposure. This is a statistic about the county's housing, not a test of any particular property - if your home predates 1980, a lead swab test is the way to check.
