Toxic Waste Sites

Data provided by the Environmental Protection Agency allows geo-spatial analysts to study the impact of toxic emissions on local communities. I obtained data from the EPA and created a map of Mississippi showing the location of toxic waste sites and the total pounds emitted:


This map shows two features – the clustering of waste sites and a smoothed visualization of their emissions. As can be seen from the map, the clustering of toxic waste sites is not necessarily a good predictor of high emissions. High emissions can also be found at single sites located in the Northeast, Southwest and just north of Jackson.

Another way to view the emissions is by creating a feature that encapsulates location and total pounds emitted. In the below map, each site is sized and colored according to the amount of total waste emitted: TOXIC EMMISSIONS TOTAL POUNDS
