How large is a site wheree hazardous waste clean up requires bioremediation?

The size of a site requiring bioremediation for hazardous waste cleanup can vary widely depending on the extent of contamination and the specific contaminants involved. Sites can range from small industrial lots to large Superfund sites covering several acres. Generally, bioremediation is applicable to areas with contaminated soil or groundwater, which can be as small as a few hundred square feet to several hundred acres. The determination of size is based on environmental assessments conducted prior to remediation efforts.
