In situ and on-site soil remediation techniques : a review

Reliable in situ and on-site remediation techniques has been compiled and summarized in order to review remedy options. These techniques have been monitored by their general function, feasible environment, target contaminants, removal efficiency, environmental impact, overall cost and compatibleness with other remediation options. Few conclusions are possible to make but a majority of the most efficient treatment methods tend to have a major environmental impact and in most remedy options cost varies substantially. Moreover, a high content of organic matter and clay combined with low permeability in multi –element contaminated soil seems to pose most difficulties for soil remedy selection. Often mentioned critical variables in soil remediation technologies are the distribution efficiency of a reactive media in the contaminated area and the reactivity of the target compound/s present. Combined treatment could generally serve to enhance contact contaminant/ added reactive media and thereby to lower emissions. Combinations of methods have been discussed based on literature.Validerat; 20101217 (root
