The use of soil fracturing coupled with sonic devices for the insituremediation of contaminated soil

摘要

The removal of hazardous substances from soil and rock is a major problem in the United States.Low permeability geomaterials such as silt,clay,or tight bedrock present a special remediation challenge,since they.exhibit low transport rates and high adsorption potential.Available and emerging treatment technologies may be generally classified as ex situ [above ground] or in situ [below ground].of these,the latter approach is generally preferred since it is less costly,and also minimizes potential exposures.
