Legal Description:            
Township 14S Range 48E    
Section 29 NW 1/4 NE 1/4 1/4

Elevation (Datum NGVD-29): 
803.12 meters AMSL (2635.4 feet) GPS

Access:  Take Highway 95 west from the Lathrop Well Junction 11.0 miles to the gate on the north side of the Highway.  Take the gravel road 0.2 miles to the turn-around on the white spring deposits.

Purpose:  1) provide lithologic samples of spring deposits; 2) define valley-fill stratigraphic sequence and groundwater flow paths down-gradient of proposed repository; 3) provide aquifer test data; and 4) provide water level and water chemistry data.

NC-EWDP-1S is located on paleospring deposits near the boundary between the Crater Flat and Amargosa Desert hydrographic basins.  The site is located down-gradient of fractured volcanic rocks that provide a pathway for groundwater flow from the Yucca Mountain area.  The paleospring deposits are of note as these types of deposits are associated with past climates.  Two zones, one in the upper Tertiary volcanics, and one in the underlying Tertiary sedimentary rocks, were selected for long-term monitoring.  Deeper zones are monitored in NC-EWDP-1D.   Prior to completion, a 48 hour constant discharge test was completed.  Water samples were collected for analysis.
