Access:  NC-EWDP-7S is in a remote location an is accessible via a poorly maintained road.   Please contact the Nye County Nuclear Waste Repository Project Office (NWRPO) to arrange access to this site.

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

NC-EWDP-7S is located on a paleospring deposit at the south end of Crater Flat.  This site was selected to determine the depth to groundwater, the chemical nature of that groundwater, and to provide samples of the paleospring deposits.  The paleospring likely discharged to the land surface in Pleistocene time during a wetter climate.  A better understanding of these spring deposits along with those at NC-EWDP-1D and NC-EWDP-9S could provide insight into the likely consequences of future climate change on the performance of a repository at Yucca Mountain.
