Content:
um, average maximum, average, average minimum, and minimum monthly river discharge and flushing characteristics (from the ER and the general literature). The following groundwater data and information should be obtained: ` the areal extent of aquifers, recharge and discharge areas, elevation and depth, and geologic formations (from the ER and the general literature) ` piezometric contour maps and hydraulic gradients (historical, if available, and current) (from the ER and the general literature) ` flow travel times (from the ER and the general literature) ` soil properties, including permeabilities or transmissivities, storage coefficients or specific yields, total and effective porosities, clay content, and bulk densities (from the ER and the general literature) ` interactions between site surface and groundwaters (from the ER and the general literature) October 1999 2.3.1-5 NUREG-1555 ` historical and seasonal trends in groundwater elevation or piezometric levels; interactions between different aquifers (from the ER and the general literature) ` recharge rates, soil moisture characteristics, and moisture content in vadose zone ` existence of any local aquifers designated or proposed to be designated as “sole source aquifers.” II.
