133119144491771, Local number, 18-3149-05 Wettengel Exploratory Well EX-7

LOCATION.--Lat 13° 31' 19' N., Long 144° 49' 17" E., Hydrologic Unit 20100003, 200 ft east of junction of Routes 1 and 3, Wettengel. Owner: Government of Guam

AQUIFER.--Barrigada Limestone

WELL CHARACTERISTICS.--Drilled basal ground water exploratory well. Sounded depth at time of drilling 698 ft, Sounded depth for this study 499 ft, Borehole diameter 8 in., Casing diameter 5 in., cased to bottom.

DATUM.—Altitude of land surface datum is 283 ft. Measuring point and new altitude (determined for this study): black inked triangle on top of PVC 6-in. casing, 282.93 ft above mean sea level. Old measuring point and previous measuring point altitude: top of steel surface casing, 283.31 ft above mean sea level.

PERIOD OF RECORD.—

Water Level: Occasional measurements, August 1981 to May 1983. Manual measurements for this study, May 17, 2004 to February 24, 2005. Water-level recorder (float system) June 1983 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, September 1981 to March 1985. Specific-conductance profiles: using Ocean Sensors conductivity-temperature-depth logger: from May 15, 2001 to February 26, 2004, and for this study, May 17, 2004 to February 24, 2005. Fixed-depth specific-conductance hydrographs, from May 21, 2004 to February 24, 2005.
