GEOCHECe-PHYSICAL SETTING SOURCE SUMMARY GEOCHECe-PHYSICAL SETTING SOURCE SUMMARY GROUNDWATER FLOW DIRECTION INFORMATION HYDROLOGIC INFORMATION Groundwater flow direction for a particular site is best determined by a qualified environmental professional Surface water can act as a hydrologic barrier to groundwater flow Such hydrologic information can be used to assist using sde-specific well data.If such data is not reasonably ascertainable,It may be necessary to rely on other the environmental professional in forming an opinion about the impact of nearby contaminated properties or,should sources of information,such as surface topographic information,hydrologic information,hydrogeologic data contamination exist on the target property,what downgradient sites might be impacted collected on nearby properties,and regional groundwater flow information(from deep aquifers) Refer to the Physical Setting Source Map following this summary for hydrologic information(major waterways and bodies of water). TOPOGRAPHIC INFORMATION FEMA FLOOD ZONE Surface topography maybe indicative of the direction of surfcial groundwater flow. This information can be used to FEMA Flood assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or.
