Biological Treatment of Contaminated Soils

John Poullain, P.E.

This three-hour online course serves as general guide for the treatment of contaminated soils. The course documents are intended to aid in the selection of remedial actions and treatment of hazardous waste contaminants by various biological methods or combinations of them. The biological treatment methods discussed include bioventing, phytoremediation, biopiles, composting, slurry bioreactor, biosparging and constructed wetlands. Treatment methods for contaminated groundwater are also discussed. Several biological methods used for soils are applicable for treating contaminated liquid. Remedial actions must comply with federal and state regulations. The text provides web links and references for additional information.

State and federal regulations have to be complied with at hazardous and toxic waste sites in order to remove any threat to human health, welfare or to the environment. Hazardous and toxic waste includes hazardous substances and pollutants. Among the substances are heavy metals, including lead, cadmium and mercury and PCBs, dioxins, chlorine, sulfur, potassium and explosives. Bioslurry Reactors and other bioremediation methods discussed can be used to decontaminate soils prior to final disposal and reduce the land needed for disposal.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
