Abstract
A process for removing contaminants from soil or aquifers. The process uses wick drains which include an outer filter medium supported by a rigid inner perforate member. The wick drains are inserted into the contaminated soil or aquifer, water is injected into one or more of the wick drains, and water and contaminants are removed from one or more wick drains. The wick drains are inserted by placing the wick drains in mandrels and driving them into the soil or aquifers, in a manner similar to that in which piles are driven, at a rate of up to about 8,000 to 10,000 linear feet per day.
