Geologic and hydrologic research at the Western New York Nuclear Service Center, West Valley, New York. Annual report, August 1981-July 1982
This report details the research accomplished during the second part of the New York State Geological Survey's (NYSGS) three part program of geologic and hydrologic investigations at the Western New York Nuclear Service Center (WNYNSC) at West Valley, New York. During this reporting period, July 1981-July 1982, the surficial gravel and the underlying till surface of the North Plateau area were measured using core log data and seismic techniques. Contour and isopach maps are included and show the surficial gravel layer to be lenticular in cross section and approximately forty feet thick at its center. The history of drilling at the site and all available subsurface information pertaining to site stratigraphy has been compiled and standardized. Geologic sections based upon the locations of all wells and their geologic logs show that a sandy stratum, previously reported to extend under the entire site at an elevation of 1350 feet, is not a continous layer. Analyses of surface and subsurface till samples show that Lavery Till can be subdivided into three subfacies using grain size distributions and the Kent Till can be distinguished from it by its higher silt content. Initial measurements for movement determination on two landslides yield an average downslope movement rate of 0.23 meters/year. A site slope domain map, establishing five domains of varying sliding potential, has been compiled from aerial photos and field mapping. The final phase of the Buttermilk Creek investigation and the study of the erosional history of the Cattaraugus Creek drainage basin have been initiated. A preliminary characterization of the relationship between precipitation and runoff on the North Plateau shows the income to outflow ratio is 3:1 during the summer and nearly equal to one in the winter.
