Part C, Section 4 Figure 18 In this document, a model for the movement of organic contaminants from soil to groundwater (see Appendix C), a model for the infiltration of volatile contaminants into indoor air via basements (Appendix H), a model for the movement of contaminants from soil into the food chain (Appendix C), and a model for the erosive movement of soil from an industrial site to an adjacent site (Appendix E) have been included. The two following examples illustrate use of these contaminant migration models. First, the guidelines derived for industrial sites should not allow for the cross-contamination of adjacent non-industrial sites by erosional forces. The model in Appendix E would call for a downward adjustment if the preliminary industrial guidelines would be projected to cause off-site contamination. Second, in an agricultural scenario, the model for bioconcentration of contaminants in food items (Appendix C) might also result in the preliminary soil guidelines being altered downward. The use of these models is described in Section 5.3. If the defined exposure scenario used in developing the generic guidelines is thought to be inappropriate for the particular site to be remediated, further guidance to allow modification of the generic guidelines 84 Significant Pathways of Human Exposure to Environmental Contamination
Part C, Section 4 within limits, through the setting of site-specific objectives has been developed (See Part A, Section 1.3.3). For example, this may involve the removal, addition, or calibration of exposure pathways to more accurately represent the exposure scenario present at a specific site. 85
