Mr. Arntzen is a geologist who supports research projects evaluating and monitoring aquatic habitat, groundwater/surface water interaction, and water quality within large river systems. Mr. Arntzen completed a graduate thesis evaluating the hydrogeology and water quality of the groundwater/surface-water mixing zone within the Hanford Reach of the Columbia River between 1997 and 2002. Since 2002, Mr. Arntzen has conducted research evaluating how physicochemical properties of the hyporheic zone affect habitat quality. His work includes evaluations of water quality, contaminant transport, and physical habitat quality, all with an emphasis on the impact to aquatic organisms that are dependent on the hyporheic zone. He has worked in areas including the Hanford Reach of the Columbia River, the Columbia River Gorge, the Snake River, and the Grayâ€™s River watershed.
