Estimated Drawdowns in the Floridan Aquifer due to Increased Withdrawals, Duval County, Florida.
Abstract
A simplified model of the Floridan aquifer system underlying Duval County consists of two highly permeable water-bearing zones separated by a semiconfining zone of relatively low permeability, all of which are confined above and below by much less permeable strata. At present (1979) only the upper permeable zone is tapped by production wells. Decreases in artesian pressure in the upper permeable zone of the aquifers induce upward leakage of water from the lower permeable zone resulting in reduced pressure in this zone. Thus, saline water from deeper strata can move upward, apparently along fractures and faults into the lower permeable zone.
