Brownfields are typically located where industrial or commercial sites used to exist. Abandoned factories and other polluting operations have been known to produce brown fields in city and town industrial sections. Urban environments can be home to brownfields as well since dry cleaners and gas stations are capable of producing brownfield sites. Any entity that produces any type of hazardous waste that travels or is placed in the land is capable of creating a brownfield. Establishments that use contaminates such as asbestos, hydrocarbon, solvents, pesticides or heavy metals such as lead have a chance of creating a brownfield. The Environmental Protection Agency can assist anyone interested in locating brownfields within their neighborhood or state. This can assist anyone interested in acquiring a brownfield or cleaning one up for safety and health reasons.
