I- 10 (1) Dd, drawdown (2) This has been calculated by the single drawdown method using the following assumptions: The maximum drawdown is reached with 24 hours pumping. Well radius is 0.1 m. S is 0.001 4.4 Golf Course No pumping tests could be found for this area.

Well radius is 0.1 m. S is 0.001 (3) This bore was pumped for sampling and a drawdown recorded. Pumping time, based on the practise of pumping three bore volumes was estimated to be 1 hour.
