Access:  Take Highway 95 north from the   Lathrop Wells Jct. 7.5 miles to the gate on the north side of the Highway.  Take the gravel road 0.15 miles north; turn east and follow the tire tracks.

Purpose:  1) provide lithologic samples of deposits; 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-3S is located along a key groundwater pathway between Crater Flat and the Amargosa Desert.  The well was completed as a satellite to NC-EWDP-3D to provide water level and water chemistry data from the upper Tertiary volcanic aquifers.  The well has three monitoring zones.  The upper zone is in the upper Tertiary volcanic rocks in a fractured, bedded tuff.  The middle zone is completed deeper in the same unit and the lower zone is completed in a thick sequence of ash fall tuffs.  Water samples were collected for analysis.
