HEC3: Exposure to Potentially Hazardous Materials


  • Morbidity and mortality from physical hazards (i.e. radiation, noise, light)
  • Morbidity and mortality from materials hazards (existing air, water, and soil hazards)
  • Morbidity and mortality from project-specific hazards (dependent on project type, i.e. coal dust for a coal mining project)


  • Human biomonitoring data
  • Subsistence food contaminant levels
  • Water quality monitoring data
  • Drinking water quality data
  • Air quality monitoring/modeling data
  • Soil quality/contamination data
  • Presence of public water systems
  • Existing contaminated sites
