Drilling and testing of a new groundwater production well APCEL 14 at Snuggery has indicated a production rate of about 8000 cubic m/day (80,000 gallons per hour), which should have only minimal effects on groundwater levels in both the upper unconfined and lower confined aquifers in the Gambier Limestone. Beneath the paper factory site, well drawdown interference should be limited to a drop of 2-3 m within the confined aquifer. The water level in the unconfined aquifer can be expected to drop by only about 1 m near the new well, because it has been cemented off from accessing this aquifer. Using the aquifer characteristics obtained during this drilling programme it can be demonstrated that the decline in groundwater levels in existing production wells over the period 1973-1975 is a result of dewatering of the upper unconfined aquifer in the vicinity of each well. The time over which this has occurred is very sensitive to pump rate and aquifer thickness: the higher the rate and thinner the aquifer, the faster the dewatering. This explains why production wells APCEL 11 and 12, with their higher pump rate and thinner aquifer, took much less time (2-4 years) to dewater the unconfined aquifer than, say, APCEL 8 and 10 (7-8 years). Groundwater level monitoring has shown essentially stable conditions in both aquifers in and around the well field. With a shift in the pumping centre at Snuggery once APCEL 14 is in production, redistribution of heads will occur in both aquifers, but these should stabilize to new equilibrium levels within a few years as APCEL do not intent to significantly change the overall production rates. Continued monthly monitoring of selected observation wells should continue.
