Coffey Geoscience has more than two decades experience preparing successful pre-partition groundwater reports in other Oregon counties and are well staffed to carry out groundwater assignments in Clackamas County. We use Oregon Department of Water Resources and Clackamas County Assessors files to locate properties and wells. These are plotted on GIS based maps that create mandated areas of influence with required quarter-mile buffers. Senior Hydrogeologist, Scott Thompson supervises these projects which are performed in our West Linn offices.
