Technical Report WRD84006 Viewed at 14:07:13 on 29/07/2010 Page 34 of 60. 6. RECOMMENDATIONS It is recommended that A water level monitoring program be undertaken to monitor water levels in the available bores. These include bores RN 8476, RN 20921, RN 20922, RN 20925 and RN 20926. Measurement should be done in accordance with recommendations made in Section 2.3.1, and at an interval of no greater than six weeks. Levelling of the bores is also required. A continuous recorder should be installed to measure water levels in bore RN 5463. Water levels in this area are considered to be representative of the general aquifer behavior and performance. Several additional observation bores are adequately monitor the aquifer's behavior. be drilled when feasible. The location of bores is shown on Figure 2.3. required to These should the required A tidal efficiency test, as should be conducted as soon enable upgrading of the model. described in Section as possible. This 2.2.2 will Future upgrading of the system to include bores RN 20927, RN 20921 and RN 6252. Table 4.2 is a summary of the recommended pumping rates which will allow a maximum of 30 Lis to be obtained. This will meet the projected 1990 requirement. A reassessment of data should take place in 1990. Based on at least five years of water level data, a revision of the model should be attempted. New recommendations for the operation, monitoring and development of the borefield may be necessary as a result. The water should be treated to raise the pH to an acceptable level. This could be achieved by aerating the water before reticulating. All future developments that may present a pollution threat to the aquifer system should not be located over the recharge area (refer Figure 2.3).
