GEOCHECK® - PHYSICAL SETTING SOURCESUMMARY <br /> GROUNDWATER FLOW DIRECTION INFORMATION <br /> 1 ' Groundwater flow direction for a particular site is best determined by a qualified environmental professional <br /> using site-specific well data. If such data is not reasonably ascertainable, it may be necessary to rely on other <br /> sources of information,such as surface topographic information, hydrologic information, hydrogeologic data <br /> F�, <br /> collected on nearby properties,and regional groundwater flow information(from deep aquifers). <br /> TOPOGRAPHIC INFORMATION <br /> Fi Surface topography may be indicative of the direction of surficial groundwater flow. This information can be used to <br /> assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, <br /> should contamination exist on the target property,what downgradient sites might be impacted. <br /> FiTARGET PROPERTY TOPOGRAPHY <br /> USGS Topographic Map: 38120-A8 VALLEY SPRINGS SW, CA <br /> General Topographic Gradient: General WSW <br /> FAi <br /> Source: USGS 7.5 min quad index <br /> SURROUNDING TOPOGRAPHY:ELEVATION PROFILES <br /> Pi <br /> c <br /> `3 w w <br /> O o N <br /> N <br /> N � <br /> Fill <br /> F <br /> } North <br /> South <br /> TP <br /> Fi <br /> F <br /> i <br /> F1 <br /> � N <br /> V <br /> Q1 J r N N N r D1 r r N pN 2 a 1 <br /> W 41 _ _ N _ .4 .�. g_ S V, �' _ N C� O _ W - . - . _ . _ . - . <br /> OI <br /> N <br /> Fj` <br /> West East <br /> TP <br /> 0 1/2 1 Miles <br /> Pf Target Property Elevation:216 ft. <br /> Fj <br /> Source:Topography has been determined from the USGS 7.5' Digital Elevation Model and should be evaluated <br /> on a relative(not an absolute) basis.
