GEOCHECK° PHYSICAL SETtING SOURCE SUMMARY `F <br /> I # <br /> GROUNDWATER FLOW DIRECTION INFORMATION <br /> .. 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 /> collected on nearby properties,and regional groundwater flow information(from deep aquifers). <br /> F11TOPOGRAPHIC INFORMATION <br /> 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 /> FTARGET PROPERTY TOPOGRAPHY <br /> USGS Topographic Map: 38121-A3 LODI SOUTH,CA <br /> General Topographic Gradient: General SW <br /> Source: USGS 7.5 min quad index <br /> SURROUNDING TOPOGRAPHY.ELEVATION PROFILES <br /> L, <br /> c <br /> p <br /> - > 9 lb NW J 6Ni A N N N N N <br /> W . .. . _ . .. . - _ _ _ _ _ _ <br /> North South <br /> TP <br /> 0 <br /> 1{^ t.7 N U t4 U <br /> i li!
