Bottom of borehole at 85.1 ft bgs

Boring terminated at a planned depth.

RQD values provided on the boring logs are based onintact core pieces obtained between two naturaldiscontinuities. The majority of core obtained from thisboring is typically very weak to weak and does not meetthe "sound core" definition provided in the standard testmethod for RQD (ASTM D 6032). These RQD valuesshould not be used to evaluate rock mass quality.

At Elev 288.4', observed bedding joint, dipping 25 to15°.

At Elev 286.8', observed fault, dipping 55°, smooth,minor offsets of SILTSTONE beds.

Bottom of borehole at 109.0 ft bgs

Boring terminated at a planned depth.

Piezometer Sensor Installed at 36.7' (El. 356.7')

RQD values provided on the boring logs are based onintact core pieces obtained between two naturaldiscontinuities. The majority of core obtained from thisboring is typically very weak to weak and does not meetthe "sound core" definition provided in the standard testmethod for RQD (ASTM D 6032). These RQD valuesshould not be used to evaluate rock mass quality.

At Elev 206.5', observed bedding joint, dipping 50°,tight.

At Elev 206.0', observed fault, dipping 70°, 1/16" thicklean CLAY lining; tight. Truncates local SILTSTONEbeds. Rock becomes soft.

At Elev 201.0', observed fracture zone, tight, with up to1/8" thick lean CLAY lining.

Bottom of borehole at 225.0 ft bgs

Boring terminated at a planned depth.

Piezometer Sensor Installed at 124.5' (El. 300.5')

RQD values provided on the boring logs are based onintact core pieces obtained between two naturaldiscontinuities. The majority of core obtained from thisboring is typically very weak to weak and does not meetthe "sound core" definition provided in the standard testmethod for RQD (ASTM D 6032). These RQD valuesshould not be used to evaluate rock mass quality.

Bottom of borehole at 271.0 ft bgs

Boring terminated at a planned depth.

Piezometer Sensors Installed at 52' and 200' (El. 493.1',and 293.1')

RQD values provided on the boring logs are based onintact core pieces obtained between two naturaldiscontinuities. The majority of core obtained from thisboring is typically very weak to weak and does not meetthe "sound core" definition provided in the standard testmethod for RQD (ASTM D 6032). These RQD valuesshould not be used to evaluate rock mass quality.
