Pump testing of existing supply well indicated high nitrate levels and limited supply life. 2 exploration wells were drilled. The first yielded greater than 800 m3/day with total dissolved salt level of 2737 mg/L. The second yielded water supply of less than 5 m3/day and 1958 mg/L. Nitrate levels were low in both wells. Sufficient alternative supplies of low salinity water have not been found at or near the opalfield. Further drilling at 2 other sites is recommended.
