Discharge and water-quality data for selected streams at low flow including some bottom-material analyses, and limnological study of six lakes, Westchester County, New York

Chemical quality of the Saw Mill River, Westchester County, New York, 1981-83

“…In 1976, bottom sediments from four sites on the Saw Mill River were analyzed by the U.S. Geological Survey for organochlorine compounds (Archer and Turk, 1977 [Analyses by the Geological Survey. Concentrations in ug/kg; concentrations of organophosphorous and other organochlorine comp.ounds were below minimum detection limits; see table 4 for a complete list of compounds on the analysis list.…”

“…The lower section of the river flows through the City of Yonkers, a heavily urbanized section of the county. Results of a 1976 study by the U.S. Geological Survey (Archer and Turk, 1977) suggest that bottom sediments in the downstream (southern) section of the river are enriched in metals and organochlorine compounds .…”
