<br />NOTES FOR CRMW -02:
<br />1. EXPLORATORY BORINGS WERE DRILLED BETWEEN JUNE 16th TO THE 18th IN 2004 USING A TRUCK MOUNTED BK -66 RIG
<br />2. BORINGS WERE DRILLED WITH A 6.75 -INCH O.D. HOLLOW -STEM AUGER.
<br />3. ELEVATIONS OF BORINGS WERE SURVEYED. LOGS ARE DRAWN TO DEPTH.
<br />4. UNES BETWEEN MATERIALS REPRESENT APPROXIMATE BOUNDARIES BETWEEN TYPES. TRANSITIONS MAY BE GRADUAL.
<br />5. PIEZOMETERS WERE CONSTRUCTED USING 2 -INCH 81 SCHEDULE 40 PVC, AND 0.02 INCH SLOTTED SCREENS. THE OUTER
<br />ANNULUS WAS NATURALLY CAVED IN THE ALLUVIUM AND PACKED WITH A MINIMUM 3' BENTONITE CHIP SURFACE SEAL. THE
<br />PIEZOMETER WAS COMPLETED WITH A CONCRETE PAD AND STEEL SURFACE CASING. GROUNDWATER LEVELS WILL FLUCTUATE.
<br />NOTES FOR CRMW -41:
<br />1. EXPLORATORY BORINGS WERE DRILLED IN 2005
<br />2. BORINGS WERE DRILLED WITH A TRUCK MOUNTED PERCUSSION DRILL RIG USING 4 -INCH HOLLOW -STEM AUGER AND 1
<br />3. 1/2 -INCH CORE SAMPLER.
<br />4. LOGS ARE DRAWN TO DEPTH.
