Aquifer Test Report Galena Airport Alaska
In August 1993, the Air Force conducted aquifer tests near the POL saddle Tank Site (ST05) at Galena Airport, Alaska. Aquifer test data was acquired in seven observation during a short-term (9.5 hour) pumping test in conjunction with downhole heat-pulse flowmeter recordings in six wells. Analysis of...
