Problem Perchlorate detected in a shallow supply well within the southern portion of the Locust Valley Water District (LVWD) has prompted interest in determining the possible existence of a deeper confined aquifer (North Shore Aquifer) that may be protected from shallow contamination (fig. 1). Previous USGS studies in this area indicate the northern part of Nassau County has a complex hydrogeologic framework (Stumm and others, 2004). A previously mapped buried glacial valley may extend and be present at this location. If such a buried valley exists, all Cretaceous age deposits (Magothy aquifer, Raritan clay, and Lloyd aquifer) may have been eroded and Pleistocene-aged deposits including the North Shore aquifer...
