A new app from Esri called “My Place History” allows you to enter addresses of places you’ve lived or spent time and see public health information for those locations. The app uses publicly available data from the EPA Toxic Release Inventory and the NIH’s known chemical database. It also has a heart attack index to show where the most heart attacks occur in the country. Future versions will include additional databases for water quality, lead contamination, cancer, mortality, and poverty. Mapping API provided by ArcGIS API for iOS.
So far, the areas I have lived in that I thought would have more toxic chemical exposure have had less, and the areas I thought would have less, have more!
