rXPLORA TORY BORING NO TrS:

1. EXPLORATORY BORINGS TH-1P THROUGH TH-6P WERE DRILLED BY TTRMC ON 7-12. 7-13
AND 7-14-2004 WITH A TRUCK MOUNTED CME-75 DRILL RIG.

2. BORINGS TH-l, TH-2, TH-3 AND TH-6. IN WHICH PIEZOMETERS WERE CONSTRUCTED, WERE
DRILLED WITH a" 0.0. HOLLOW STEM AUGERS.

3. BORINGS TH-4 AND TH-5 WERE DRILLED WITH 4-INCH DIAMETER, SOLID STEM. CONTINUOUS
FLIGHT AUGERS.

4. BORING LOCATIONS AND ELEVATIONS WERE LOCATED WITH A HAND-HELD GPS UNIT AND
SPOTTED ON THE OVERALL MAP.

5. LINES BETWEEN SAMPLED MATERIALS REPRESENT APPROXIMATE BOUNDARIES BETWEEN TYPES.
TRANSITIONS MAY BE GRADUAl.

6. GROUNDWATER LEVELS SHOWN ON THE BORE LOGS WERE MEASURED AT THE TIME OF
DRILLING. GROUNDWATER LEVELS WILL FLUCTUATE SEASONALLY WITH RESERVOIR LEVEl.
