Toxic Air and America's Schools
USA Today have used Google Maps to show the locations of 128,000 schools and track the path of industrial pollutants. The aim of the site is to enable parents to determine the exposure levels to toxic chemicals of schools in their area.
It is possible to view each school on its own individual web page with a Google Map showing its location, the location of nearby schools and the locations of nearby industrial polluters. The page will also tell you in which percentile the school is and how many schools in the country have worse pollution.
The individual school pages also chart the school's exposure to cancer-causing toxics and exposure to other toxic chemicals using two simple graphs. The graphs show the school's exposure on a simple best to worst scale.
