I- 11 4.6 Discussion 4.6.1 Cainozoic Two of the bores above appear to be in alluvium. RN 6038 in the Golf Course area has a very thin saturated zone and is guessed to have a K of less than 20 m/day. RN 13624 has an estimated transmissivity of 82 m2/d. It may not have fully penetrated the aquifer. 4.6.2 Weathered Proterozoic Five bores were identified as yielding water from the weathered zone, and possibly a sixth. Transmissivities range from <0.05 to 39 m2/d, and K from < 0.005 to 6 m/d. For modelling a typical value would be <1 m/d. 4.6.3 Proterozoic Four bores were identified as producing water from the crystalline Proterozoic rocks, and a fifth possibly. Transmissivities range from <0.05 to 1 m2/d, and K from <0.02 to 7 m/d. It can be expected that permeability will depend on the presence and orientation of fractures. 4.7 Future Work If better estimates are needed it would be possible to carry out small scale pumping tests on some of the monitoring bores, using a small submersible pump. This would give significantly improved estimates, and give information on aquifer depth and hence which unit it is in. 4.8 Slug tests
