dc.description.abstractDuring the period August, 1971 to April, 1973, water and stream-bottom sediment samples were collected from 225 sites distributed throughout the Maumee River basin in northwestern Ohio, southeastern Michigan and northeastern Indiana. Split sediment samples were treated with a weak and a strong extractant before being examined by an atomic absorption spectrophotometer. Water samples were analyzed without specific preparation. The water and sediment samples were analyzed in order to determine the concentration of Ag, Al, As, Cd, Co, Cr, Cu, Hg, Ni, Pb, Sn, Sr, and Zn. The concentration of these elements in both water and sediment included a wide range, but in most cases, the concentrations in water are very small while in sediment it may be very large. Seven municipalities within the basin are characterized by large concentrations of one or more elements in water or sediment. These localities include Fort Wayne and Butler, Indiana; Hudson, Michigan; and Maumee, Findlay, Defiance, and Decatur, Ohio. The high concentrations are probably the result of Industrial and municipal waste disposal. Not all anomolous concentrations are restricted to industrial centers. A large number of samples from small streams in rural areas contained high concentrations of arsenic, mercury, lead, zinc and nickel. These may be related to the agricultural use of pesticides. A natural source, however, may be related to the discharge of mineralized ground water, which reflects the chemical composition of the strata through which the water has migrated. Some high concentrations may be more apparent than real, particularly for those elements characterized by a low wave length. This is due to instrument error, and analytical techniques. In particular, these elements include arsenic, mercury and tin.en
