Abstract

Industries in the Nikiski area pumped about 4.2 million gallons of water per day from three aquifers in 1979. The upper confined aquifer, from which most of the water is pumped, is recharged by leakage from the overlying unconfined aquifer. The unconfined aquifer is hydraulically connected to lakes and streams. The lower confined aquifer, the deepest of the three aquifers, is hydraulically poorly connected to the other two aquifers. Drawdown caused by pumping appears to have stablized in all three aquifers, but water levels continue to fluctuate in response to annual changes in precipitation. In the lower two aquifers, the potentiometric surfaces near some production wells are below sea level; however, no salt water had intruded the aquifers as far as the pumped wells. If additional water supplies are needed, another potential site for ground-water development is the Beaver Creek basin, 7-10 miles east of the industrial area. (USGS)
