The freshwater lens on Home Island in the Cocos (Keeling) Islands
Groundwater resources have been investigated on Home Island, in the Cocos (Keeling) Islands, Indian Ocean, to assess the prospects of developing a reticulated water supply and sewerage system for the settlement there. Home Island is part of the South Keeling atoll and contains a lens of fresh groundwater overlying sea water. Measurements of water-levels in existing wells, and levelling with respect to mean tide-level, indicate that theoretically the freshwater lens is up to 19 m thick, and averages about 15 m over an area of about 30 hectares. Allowing for tidal fluctuations and for periods of drought, the sustainable yield of the aquifer would be about 200 000 litres per day. Recommendations have been made for the development of the aquifer by pumping from infiltration galleries; pumping should reduce the lens thickness by no more than half if saltwater contamination is to be avoided.
