GEOCHECK® PHYSICAL SETTING SOURCE ADDENDUM <br /> TARGET PROPERTY ADDRESS <br /> LINNE ESTATES <br /> LINNE ESTATES <br /> TRACY,CA 95376 <br /> TARGET PROPERTY COORDINATES <br /> Latitude (North): 37.696491 -37'41'47.4" <br /> Longitude (West): 121.398811 - 121'23' 55.7" <br /> Universal Tranverse Mercator: Zone 10 <br /> UTM X(Meters): 641165.6 <br /> UTM Y(Meters): 4173142.2 <br /> EDR's GeoCheck Physical Setting Source Addendum has been developed to assist the environmental professional <br /> with the collection of physical setting source information in accordance with ASTM 1527-00, Section 7.2.3. <br /> Section 7.2.3 requires that a current USGS 7.5 Minute Topographic Map(or equivalent,such as the USGS Digital <br /> Elevation Model) be reviewed. 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 /> I <br /> f <br /> 4 <br /> r <br /> F <br /> t <br /> F <br /> k <br /> j TC890744.3s Page A-1 <br /> a <br /> l <br /> i <br />
