Water quality studies within the Eagle Creek watershed, Indiana, were done by the U.S. Geological Survey in August 1980, October 1982, and December 1982 in cooperation with the city of Indianapolis, Department of Public Works. Streambed-material and water samples were collected from Finley and Eagle Creeks at various flow rates and were analyzed for selected metals, non-metals, insecticides, and acid-extractable and base-neutral-extractable compounds. Water samples also were analyzed for volatile organics. This report lists all the data collected and analyzed by the U.S. Geological Survey during the 1980 and 1982 surveys but does not interpret the data. (Author 's abstract)
