Superfund Sites More Dangerous Than Brownfields: When compared to a Brownfield site, Superfund sites and their cleanup are considered more carefully, and for good reason. Usually, these sites are not simply abandoned industrial areas but rather have experienced active dumping of dangerous chemicals in the past. These sites usually have unsafe contamination levels of petroleum products, toxic chemicals or both.
This increases the dangers associated with cleanup so the EPA oversees the projects internally. There are, however, some opportunities for communities wishing to get involved in the process in some way.
