The description, location, log and meter tests of all the drilled wells on Oahu are given herein as of March 1 1938. Except for the discharges of plantation wells, which are published on pages 275 to 322 of Bulletin 1, head, chloride, and discharge records are listed only to the close of 1934, the date when this report was compiled. All head measurements and salt determinations made by the U.S. Geological Survey since 1934 will be found in the annual U.S. Geological Survey Water-Supply Papers entitled “Water levels and artesian pressure in observation wells in the United States.” Records of wells in the district of Honolulu are currently printed in the biennial reports of the Board of Water Supply, Honolulu. Most of the records of the plantation wells have been furnished by the owners.
Plate 2 shows the location of the wells, whether they are sealed, and whether the log is known. The static level or head of a well is the height above mean sea level to which the water will rise when all flow from the well is shut off. In the nonartesian wells the static level is the level of the water table of the basal zone of saturation in the basalts of the Koolau and Waianae volcanic series. Many of the wells are subartesian; that is, the water stands in the well above the level at which it was first encountered but does not overflow.
