Eight “layers” Toxic Chemical Releases Lead Hazards Superfund Smog and Particulates Hazardous Air Pollutants Clean Water Act Watershed indicators Animal Waste Environmental justice analysis Health effects data 400+ databases TRI Air Quality System National Emissions Trends National Air Toxics Asst. US Census California chemical lists Risk scoring systems 100 Gb of data processed to 5-7 Gb Scorecard’s Structure

  6. Data integration • Scorecard uses set of identifiers to align datasets • CAS numbers, FIPS codes, facility identifiers • Creates tables of releases aggregated by zipcodes, counties, states • Raw release data converted to toxic equivalencies, risk scores, sorted by health effect • Over 100 scripts run to generate ranking tables and graphics

  7. Maintaining a rich resource…

  8. Summary • Scorecard uniquely combines EPA exposure and release data with health effects data • Future of Scorecard unclear at this point
