Industrial Park Several factories exist in an area near the wetlands called Industrial Park. The site was a good location because it was near a river and a major highway that could both be used to ship and receive products for the factories. The following is a list of the factories and some of the plastics and metals that they ship or receive that might be linked back to the illegal dump site.
