Access:  From the intersection of US Highway 95 (US 95) and Highway 373, head west on US 95 about 6.2 miles and turn left onto an unnamed dirt road.  There is an unlocked gate at the edge of the US 95 right-of-way.  Proceed south along the unnamed dirt road about 0.7 miles and turn east (left).  Continue about 0.6 miles along the unnamed dirt road to the cleared well pad area. The well is in the northeast corner of the pad.   Click on the thumbnail image for a larger view.

Purpose
- Water Resource Conditions in the Amargosa Desert: 
NC-GWE-33PA is one of seven boreholes and monitoring wells to:
1) collect baseline flow and chemical data south and west of the Nevada Nuclear Security Site, and 2) determine head relationships near the Gravity fault to help determine the role of the Gravity fault in restricting or facilitating groundwater flow in the Amargosa Valley.
