Hydrogeologic Investigation and Lineament Analysis

An investigation of the geology of the study area will be made. This will include a review of literature, geologic maps and well logs and a field investigation. The field investigation is necessary to confirm the accuracy of the geologic map and to identify important geologic features not on the map, such as joint sets, prominent bedding plane partings, chert or shale beds that might constitute confining layers, etc. A lineament analysis will be performed for the area within and surrounding the study area. Lineaments and fracture traces will be identified from topographic and geologic maps, the county soil atlas and aerial photographs. This information combined with field measurements of joints, strike and dip, etc. will provide indicators of possible groundwater flow routes. It will also provide important information for locating monitoring wells if needed. A map will be prepared showing the lineaments identified in the area.
