Owen Stefaniak is a Physical Scientist with the Upper Midwest Water Science Center.

Owen Stefaniak is a Physical Scientist with the U.S. Geological Survey Upper Midwest Water Science Center, Wisconsin office. His current research interests focus broadly on investigating anthropogenic impacts on surface water quality. He has been involved in a range of projects including assessment of organic contaminants in sediment and porewater of Great Lakes tributaries, monitoring aircraft and pavement deicer runoff in airport adjacent waterways, extent of waterborne pathogens and pharmaceutical compounds in rivers and streams, and monitoring concentrations of polycyclic aromatic hydrocarbons (PAHs) in urban stormwater runoff. He has also participated in field efforts that support investigations of harmful algal toxins in the Fox River/Lake Winnebago watershed, and polychlorinated biphenyls (PCBs) in the Clinton River Area of Concern. Prior to joining the Upper Midwest Water Science Center, Owen worked as a marine science technician on the U.S. EPA research vessel Lake Guardian (2014-2018), and a science educator on the educational tall ship S/V Denis Sullivan (2011-2014). In addition to the EPA's biannual long-term monitoring cruises, his time on Lake Guardian included field work on a diverse range of projects including the Great Lakes Sediment Surveillance Program, CSMI benthic monitoring in Lakes Erie, Michigan, Superior, and Huron, and the National Coastal Condition Assessment survey of the Huron-Erie connecting corridor. He has broad experience in pelagic monitoring and sampling methodologies as well as the planning and logistics of offshore scientific operations. He holds a U.S. Coast Guard 100-ton near coastal master's license.
