Environmental Effects
- Lead risk from housing
- Proximity to hazardous waste facilities
- Proximity to National Priorities List sites (Superfund Sites)

In addition to health measures, the EHD map also includes overlays. These are sets of information that are not used as part of the rank calculations. Overlay examples include locations of hospitals or hazardous waste sites. Currently, there are over 30 overlays (PDF) that can be selected to show more related information to the population in a specific community in Washington.
