Scorecard ranks geographic areas or pollution sources by health risks, pollutant exposures or toxic chemical releases. First select what you want to rank -- states, counties, zip codes or facilities. Then select your ranking criteria -- hazardous air pollutants, smog and particulates, toxic chemical releases, Superfund sites, lead hazards in housing, or animal waste. Result pages let you modify your ranking criteria, or drill down to local geographic areas.
