ABSTRACT:
Hydrocarbon contaminated soil from the excavation of a leaking underground storage tank is physically and chemically stabilized by combining the soil with a lime substance which is hydrated to form a flowable mixture. This mixture can then be used to fill the excavation and, if applicable, can be flowed around a replaced storage tank creating a low permeable liner. This monolithic mass prohibits hydrocarbons and heavy metals in the soil from leaching into the vicinity groundwater and prohibits leaking from possible future tank ruptures.
