During an environmental investigation, contaminant exposure risk is evaluated through several pathways. These exposure pathways include drinking water, direct contact, groundwater/surface water interface (GSI), and particulate or vapor inhalation. A conceptual site model (CSM), which is used to visualize the various exposure pathways that are applicable to a facility, is constructed through site characterization via soil and groundwater analytical data, soil borings, etc. If the level of exposure risk is unacceptable at a facility, the pathway is deemed potentially complete and additional action is necessary.
In the environmental field, an assortment of tools are available to characterize a facility during an environmental assessment. Recently, Envirologic has utilized various specialized methodologies to evaluate contaminated sites and study potential exposure pathways. The following tools have been incorporated into the Envirologic toolbox for environmental investigations.
