Technical Report WRD91026 Viewed at 15:07:48 on 29/07/2010 Page 43 of 107. To prevent future bores drilled into this aquifer from interfering with '.ater levels in other bores in the aquifer, available data indicates that bores should be located at least one kilometre apar't. 4.7 FURTHER IN';'ORMATION REOUIRED It should be noted that an assessment is only as good as the data used for that, assessment. Additional information required for a more accura'te assessment of the groundwater resource at East Alligator to 'take place is as follows; 4.7. 1 Water Leyel.. More frequent wate,r level measurements are required, at least on a monthly basis, from RN 20559 and 20636. Provision should be made for taking water level measurements in the pumped bores RN 23449 and 23450 on a monthly basis, but also at times when bore pumps fail to prod,.lce. The available water level information is insufficient for an accurate assessment to be made. 4.7.2 Metering The meters on the pumped bores and storage tank outlets should be read, preferably on a weekly basis during the dry season, to ascertain the amount of water being taken from the aquifer. The present demand for water has been estimated based on monthly visitor numbers and an assumed per capita usage. A more accurate assessment of the groundwater resource would result from knowing the actual water usage. 4.7. 3 Geophysics Further geophysics is needed to ascertain the extent of the aquifer, and to aid in future bore site selection. The resistivity technique was utilised with success in 1980 to locate prospective sites. Diagram 4 shows the traverse 10Gation and Diagram 6, the results. 005MJ
