I am trying to create a map of all Superfund sites in the U.S., and of course it isn't as easy as I thought it would be. I think I have downloaded all the necessary information, but can't figure put how to create this map. I have a basemap, I downloaded the shapefiles from the EPA, but now I am stuck. When I unzip the shapefiles, I have a bunch of excel tables, some of which do contain latitude, longitude information. I just need to do some preliminary mapping for a future project.
