Between March and April 2010 SOPAC and the Government of Nauru conducted a survey of every well in Nauru to determine water quality, usage, and possible areas of contamination.
Nauru has no significant surface water resources, limited groundwater resources, and is extremely vulnerable to drought.

Water for domestic use comes from a mixture of desalinated water delivered by truck, rainwater harvested from roofs, non-potable coastal groundwater, seawater and limited use of the thin freshwater lens found under Nauru’s central plateau. Two locally based teams surveyed 336 wells by going house to house over 5 weeks. 30% of Nauru’s population rely on water from domestic wells for bathing, washing, general cleaning, and toilet flushing.
