EXPLORATORY BORINGS WERE DRILLED FROM JANUARY 26, 1987 TO JANUARY 28, 1987 WITH A 4-INCH DIAMETER CONTINUOUS FLIGHT POWER AUGER AND A 7-INCH DIAMETER CONTINUOUS FLIGHT HOLLO'll STEM POWER AUGER. 2. ELEVATIONS AND LOCATIONS OF BORINGS WERE MEASURED BY KNAPP ENGINEERING AND SURVEYING SERVICES. 3. THE BORING LOCATIONS AND ELEVATIONS SHOULD BE CONSIDERED ACCURATE ONLY TO THE DEGREE IMPLIED BY THE MElItOD USED. 4. THE LINES BEll/EEN MATERIALS SIlOWN ON THE BORING LOGS REPRESENT TIlE APPROXIMATE BOUNDARIES BETWEEN MATERIAL TYPES AND THE TRANSITIONS MAY BE GRADUAL. 5. GROUND WATER LEVELS SIlOWN ON THE LOGS WERE MEASURED AT THE TIME AND UNDER CONDITIONS INDICATED. FLUCTUATIONS IN THE WATER LEVEL MAY OCCUR WITH TIME. 6.
