Access:  Take Highway 95 north to the Nevada Test Site (NTS) Gate 510 access road; turn north.  Go north about 1.8 miles to the gravel road just south of the NTS boundary; turn east and go 1.4 miles.

Purpose:  1) provide lithologic samples of deposits; 2) define stratigraphic sequence and groundwater flow paths down-gradient of proposed repository; and,  3) provide water level and water chemistry data.

NC-EWDP-5S is located adjacent to an existing powerline road immediately south of the Nevada Test Site boundary.  The site was selected for a shallow (500 feet) well to help define the hydraulic gradient between the Lathrop Wells area and Rock Valley.  The borehole was drilled and logged to a total depth of 1,200 feet.  During drilling, the first 500 feet were drilled with no indication of water, however, after a break in operations, groundwater was measured at 375 feet below land surface.  The borehole was advanced to a total depth of 1,200 feet and a single piezometer was set for long-term water level and water chemistry monitoring.
