Removing metals from soil
Article Abstract:
An untried treatment technology, called soil washing/soil leaching and developed by Bescorp, Fairbanks, Ala, was undertaken by the US army in the summer of 1993 to remove the metals-contaminated soils. The process resulted in the successful removal of lead. 9 tons of live ammunition, 37 tons of bullet projectiles and 100 tons of cartridge casings were also recovered. This project has given new hope for future progress in transforming hazardous metals for beneficial reuse. The proceedings of the project has been described.

Soil heating quickly captures contaminants
Article Abstract:
A six-phase heating system for soil has been set up by the Department of Energy Pacific Northwest National Laboratory in Richmond, Washington DC. The soil-venting system is designed to treat soil with a high water content. It is cost-effective in comparison to other treatment technologies. Pilot systems have been installed at various treatment centers in the US such as the one at Fort Richardson, Alaska. The technology costs up to 85 dollars per cubic yard.

Oil in the soil
Article Abstract:
Soil polluted by light sweet crude oil near Milan, Italy, was cleaned through a combination of land-farming, biopiling, bioventing and bioslurping, or vacuum-enhanced pumping. Approximately 95% of the crude oil was recovered over 18 months and the land was returned to active farming.
