No. NC-EWDP-12D SITE SUMMARY
36o 41' 37.057" North
116o 35' 13.992" West
Township 14S Range 48E
Section 32 NW 1/4 SE 1/4
774.56 meters AMSL (2,541.18 feet) GPS
Access: Take Highway 95 west from the
Lathrop Wells Junction 12.9 miles to the gravel road on the south side of the
highway. Go south 0.3 miles, turn east on the powerline road. Follow the road
for 0.4 miles and take the right fork in the road. Continue another 1.7 miles to
the well site located on a slight rise.
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-12D is located in the northwestern Amargosa Desert
about one mile south of the wells at NC-EWDP-1D and about 1.25 miles west of the well at
NC-EWDP-9S. The Highway 95 Fault runs between NC-EWDP-12D and the other two sites.
Three piezometers (NC-EWDP-12A, 12B and 12C) have been installed to serve as
observation wells for a test of NC-EWDP-12D. This test is designed to determine if
there is hydraulic leakage across the Highway 95 Fault. Current plans call for the
completion and testing of NC-EWDP-12D in EWDP Phase III.
