EX-10 Exploratory Well

133224144495271, Local number, 18-3249-02 Finegayan Exploratory Well EX-10

LOCATION.--Lat 13° 32' 24' N., Long 144° 49' 52" E., Hydrologic Unit 20100003, near NAVCAMS housing area, 200 ft East of Route 3, Finegayan, Guam.

AQUIFER.--Barrigada Limestone

WELL CHARACTERISTICS.--Drilled basal ground water exploratory well. Sounded depth at time of drilling 704.5 ft, Sounded depth for this study 488 ft, Borehole diameter 8 in., Casing diameter 5 in., cased to bottom.

DATUM.—Altitude of land surface datum is 348 ft. Measuring point and new altitude (determined for this study): black inked triangle on top of PVC 5-in. casing, 348.24 ft above mean sea level. Old measuring point and previous measuring point altitude: top of steel surface casing, 348.54 ft above mean sea level.

PERIOD OF RECORD.—

Water Level: Occasional measurements, September 1981 to May 1984. Manual measurements for this study, May 17, 2004 to February 24, 2005. Water-level recorder (float system), June 1984 to May 2004. Water-level recorder, this study, May 21, 2004 to February 24, 2005.

Water Quality: Occasional chloride, various other constituents, and specific conductance measurements from thief sampler at specific depths, July 1982 to April 1995. Specific-conductance profiles: using Ocean Sensors conductivity-temperature-depth logger: from December 5, 2000 to February 26, 2004, and for this study, May 17, 2004 to February 23, 2005. Fixed-depth specific-conductance hydrographs, from May 17, 2004 to February 23, 2005.
