WERI's National Mandates

Under the Water Resources Research Act of 1964, the National Institutes for Water Resources Research are explicitly charged to 1) arrange for competent research that addresses water problems or expands understanding of water and water-related phenomena, 2) aid the entry of new research scientists into the water resources fields, 3) help train future water scientists and engineers, and 4) get results of sponsored research to water managers and the public.

WERI's Objective

Trustworthy and timely scientific research, instruction, and advice to support sustainable development and effective management of the freshwater resources of Micronesia.

WERI's Mission

Trustworthy and timely research, instruction, and advice to support scientifically informed development and effective management of the freshwater resources of Guam, CNMI, and FSM.

WERI's Vision

WERI’s vision is to remain the acknowledged local and regional source of choice for scientific and technical advice on water resource exploration, development, and management; and a nationally-ranked and internationally recognized center of excellence for research in its strategic specialties.
