Record of ground-water exploration and development, 1975-76, Moen, Truk, eastern Caroline Islands

The exploration for and development of ground water described in this report consisted of the drilling and testing of 22 holes and the conversion of 8 of the holes into production wells on the island of Moen, Truk Islands, in the period November 1975 to July 1976. The objective of the program was to find sources of water to provide an improved supply for the reservoirs and pipelines of the Moen water system. The bulk of the report consists of records collected at the drilling sites during drilling and testing. Given for each test hole are a description of the drilling operation; a record of development of the hole; a record of each pumping test; and a log of the hole giving a summary description of rock units penetrated by the bit. For wells, there are records, where they are available, of the reaming of test holes to production-well diameter; data on casing, screens, gravel pack, and grout seal; and records of pumping tests.
