Soil remediation description

Sources of tliis information include site descriptions mid data from the preliminary assessment (PA), site inspection (SI), and remedial investigation (RI) reports. Other sources include local soil sur eys, wetland maps, aerial photographs, and reports by the National Oceanograpliic and Atmospheric Association (NOAA) and tlie U.S. Geological Sur ey (USGS). One cmi also consult with appropriate tecluiical e.xperts (e.g., hydrogeologists, air modelers) as needed to cluuacterize tlie site. 

Based on these studies, the utilization for surfactants as a soil-washing agent appears to be a promising strategy for many future site remediations. Figure 3 illustrates three conceptual systems that will aid the description of the physicochemical concepts of CAD partitioning in the systems of soil and micellar surfactant solution. 

Present a general description of remediation processes for saline and sodic soils. Explain a possible modification of these processes for polluted soils in your country. 

Modelling in the field of soil and groundwater remediation usually requires to deal with a complex system of processes and interactions among a mixture of reactive solutes as well as between the solutes and the solid phase. In hardly any case this system is completely known. And, therefore, mathematical models must use simplified approaches. Most of the models are based on descriptions including parameters that cannot be measured or directly derived from site characteristics relevant to contami-...
