摘要

AbstractContamination of soil and sediment by pollutants represents a major environmental challenge. Remediation of soil during the original Superfund years consisted primarily of dig and haul, capping, or containment. The 1986 amendments to CERCLA—SARA—provided the incentive for treatment and permanent remedies during site remediation. Thermal treatment, which routinely achieves the low cleanup criteria required by RCRA land‐ban regulations, became one of the major technologies used for cleanup under the concept of ARAR. As the remediation industry matured and recognized specific market niches in soil remediation, a number of new technologies emerged. Thermal desorption, bioremediation, soil vapor extraction, soil washing, and soil extraction are being used on sites at which the technology offers advantages over incineration. In addition, a continuing stream of emerging technologies is being presented that requires careful evaluation relative to existing cleanup methods. Each of these technologies offers a range of options for achieving appropriate cleanup criteria, application to different soil matrices, cost, time of remediation, and public acceptability. Balancing cleanup criteria defined by regulation or risk assessment with technology cost and capability affords the opportunity to solve these problems with appropriate balance of cost and protection of human health and the enviro
