It also requires that one or more additional physical setting sources be sought <br /> when(1)conditions have been identified in which hazardous substances or petroleum products are likely <br /> to migrate to or from the property, and(2)more information'than is provided in the current USGS 7.5 Minute <br /> Topographic Map(or equivalent)is generally obtained, pursuant to local good commercial or customary practice, <br /> to assess the impact of migration of recognized environmental conditions in connection with the property. Such <br /> additional physical setting sources generally include information about the topographic, hydrologic, hydrogeologic, <br /> and geologic characteristics of a site, and wells in the area. <br /> Assessment of the impact of contaminant migration generally has two principle investigative components: <br /> + 1.Groundwater flow direction,and <br /> 2.Groundwater flow velocity. <br /> • Groundwater flow direction may be impacted by surface topography, hydrology,hydrogeology,characteristics <br /> of the soil,and nearby wells. Groundwater flow velocity is generally impacted by the nature of the geologic strata. <br /> EDR's GeoCheck Physical Setting Source Addendum is provided to assist the environmental professional in <br /> forming an opinion about the impact of potential contaminant migration. <br /> i <br /> TC1302893.2s Page A-1 <br />
