FSM’s inhabited islands possess a considerably diverse range of freshwater systems. Approximately 60% of its water resources consists of surface water in the form of small streams, which are low for approximately 20% of the year. The other 40% is groundwater in small, dispersed sediment formations that are not suitable for drilling wells due to the high cost of drilling. Water storage problems are compounded from the unpredictability involved in seasonal rainfall variations associated with ENSO, droughts, and damage resulting from extreme weather events. Sea-level rise is likely to worsen issues of salt intrusion into groundwater and soils. Increased sea-levels also increase the risks of damage to water supply infrastructure from natural hazards.
