Which counties score best and worst on the EPA Environmental Quality Index?
Using the published EPA county Environmental Quality Index, which counties sit at each end of the national distribution?
What this study shows
Counties at both ends of the published overall index value, with their national group. The published scale states which direction is better.
What it cannot show
The index is a composite of historic domain measures for 2006–2010. It describes county conditions over that period and says nothing about an individual's exposure or about any health outcome.

Association is not causation: co-occurrence in the same county does not show that any exposure caused any outcome.
