TRACE METAL CHRONOLOGIES IN SEDIMENTS OF SARATOGA LAKE, NEW YORK

Dated sediments from Saratoga Lake provide historical insights on the development of Saratoga County, NY. Sediment cores from the deepest part of the lake provide near-ideal, unmixed radionuclide profiles--allowing for concise depositional modeling. Gamma counting was used for Cs-137 and Pb-210 analyses which yielded most consistent dating assignments. Several metals including lead, zinc, copper, and chromium were determined with high precision by X-ray fluorescence (XRF) analysis. The history of leather tanning around the lake, which dates back to approximately 1920, produced effluent with high chromium salt concentrations reflected in the sediment chronology. The chronologies and radionuclide-normalized inventories of the trace metals were compared to those reported for other freshwater systems in the northeast.
