The studies sources: MH's "sources included the Environmental Protection Agency's (EPA) most recent tally of facilities creating hazardous waste; the EPA's Total Environmental Release data (courtesy of Scorecard.org), a.k.a. the amount of that waste being released into the air, water, and land; and, lastly, the number of Superfund sites, places so dirty they qualified for federal cleanup funds."
