Honolulu (HI): Water Resources Research Center, University of Hawaii at Manoa. WRRC special report, 07:21:87.http://hdl.handle.net/10125/18131The 'Ewa caprock aquifer has been a long-standing water source for southern Oahu, but the freshwater viability of the aquifer is being threatened with a gradual increase in the salinity level of pumped aquifer water in recent years.
