ABSTRACT
The main report provides a comprehensive summary of the currently available hydrogeologic information and data for American Samoa and then details and prioritizes the existing knowledge gaps that hinder progress towards a more water sustainable future. The report provides necessary background by covering the conceptual hydrogeologic model of the island and by presenting available recharge estimates. All available groundwater well data including average chloride concentrations (Cl-), drilling water levels, pumping water levels, well pump-rates, and values of aquifer specific capacity, transmissivity (T) and hydraulic conductivity (K) from aquifer tests is organized by wellfield and presented for all known current and historical wells on Tutuila. The report concludes by providing water management recommendations for groundwater use and development, aquifer testing, and for filling hydrogeologic data gaps.
