Mr. Krause is an experienced hydrogeologist with a strong technical background. He designs, conducts, and manages investigations and remediations at contaminated sites involving a variety of contaminants, including petroleum and chlorinated hydrocarbons and fill-related organic and inorganic compounds. He is experienced in planning and executing remedial activities, including excavation, in-situ chemical oxidation, monitored natural attenuation of groundwater, vapor mitigation, and construction of engineering barriers. Additional experience includes aquifer characterization by collecting and analyzing hydraulic conductivity data using straddle packers in bedrock boreholes; sampling groundwater for human enteric viruses and emerging contaminants; and developing geologic and hydrologic inputs for groundwater flow models using ArcGIS and MODFLOW.
