f <br /> OW w+rt <br /> GEOCHECK® PHYSICAL SETTING SOURCE SUMMARY <br /> .: <br /> F1 GROUNDWATER FLOW DIRECTION INFORMATION <br /> Groundwater flow direction for a particular site is best determined by a qualified environmental professional <br /> i 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 /> �j collected on nearby properties, and regional groundwater flow information(from deep aquifers). <br /> TOPOGRAPHIC 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 /> TARGET PROPERTY TOPOGRAPHY <br /> USGS Topographic Map: 38121-B2 LOCKEFORD,CA <br /> General Topographic Gradient: General North <br /> F# Source: USGS 7.5 min quad index <br /> F1 <br /> SURROUNDING TOPOGRAPHY:ELEVATION PROFILES <br /> Fj <br /> o , <br /> W 4 - V.- ld. -;j - 1. - v- - S - <br /> i <br /> F!
