Excavation of contaminated soil from a site involves digging it up for “ex situ” (above-ground) treatment or for disposal in a landfill. Excavation also may involve removing old drums of chemicals and other buried debris that might be contaminated.
Soil contamination is considered hazardous waste and needs to be professionally removed and treated right away. Contaminated soil can become a major problem if you don’t take care of it quickly. When left in place, contaminated soil can leach toxic chemicals into the ground and surface waters.
There are many methods of treating or cleaning-up contaminated soils/sediments including both in-situ (treating in the ground) and ex-situ (removal of soil to treat) remediation considerations. The main methods used include: containment, soil washing, thermal treatment, vapor extraction, bio-remediation, incineration, and other physical ...
The Citizen's Guide series is a set of 22 fact sheets that summarizes cleanup methods used at Superfund and other sites. This guide covers Excavation of Contaminated Soil in which polluted soil is removed and transported to another location to be treated or destroyed.
Excavation of contaminated waste, such as soil, sludge and debris from a site, involves digging it up for “ex situ” (aboveground) treatment or for disposal in a landfill. Excavation also may involve removing old drums of chemicals and other buried debris.
Before treatment standards apply to contaminated soils, a soil must first “contain” hazardous waste. Under RCRA, soil is not a solid waste, but is must be managed as a hazardous waste if it “contains” hazardous waste.
What is Contaminated Soil? Soil containing chemical compounds potentially harmful to human health or the environment; contamination from sources that are not naturally occurring (i.e. man-made).
The basic approaches to cleaning contaminated soil include: Containment. Bio-remediation. Chemical oxidation. Soil washing. Thermal treatment. Containment. Soil containment involves containing the soil in one spot so that any contaminants do not spread.
