GROUND-WATER YIELD AND POTENTIAL FOR IRRIGATED AGRICULTURE IN THE AREA OF THE NAVAL MAGAZINE AND RADIO TRANSMITTING FACILITY, LUALUALEI, OAHU, HAWAII

It appears likely that an estimated additional two million gallons per day of fresh and slightly brackish water can be developed in Lualualei Valley for the agricultural outleasing project. Several additional wells could be located in the volcanic aquifer which presently produces water of excellent quality. A secondary line of wells designed to develop water from the coralline aquifer would capture the flow not captured by the wells in the volcanic aquifer. The chloride concentration of the water pumped from these wells is expected to range between 500 and 1,500 milligrams per liter. The amount of acreage devoted to crops would depend primarily on the water quality and quantity requirements of the type of crops cultivated and on the type of irrigation system employed. The remaining acreage could be allocated for pasture to graze beef cattle.
