Access:  From the intersection of Highway 95 and Highway 373, go west on Highway 95 approximately 0.2 miles to the intersection of Highway 95 and the Gate 510 road, go north 1.8 miles to powerline road just short of the 510 gate, and go west 2.5 miles along powerline road.

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

NC-EWDP-19D is located along a key groundwater pathway between Yucca Mountain and the Amargosa Desert.  This site was selected to define the number and types of aquifers present in the Fortymile Wash area down-gradient of Yucca Mountain.  The 19D site is the location of the Alluvial Testing Complex testing facilities.  Current plans include drilling injection wells and monitoring wells to be used in future tracer tests.  The lower part of the 19D borehole was deviated and was partially grouted and redrilled at the same location.
