Upper Floridan: Southern Coast
Water levels in three wells were used to define groundwater conditions in the Upper Floridan aquifer in the southern coastal area of Georgia. In this area, water in the Upper Floridan aquifer is confined and influenced mostly by pumping to the south in the Fernandina Beach area, Florida, and by climatic effects and pumping to the west. Hydrographs for selected wells (below) illustrate monthly mean water levels for the period of record. The hydrographs show periodic upward or downward trends that primarily reflect changes in pumping.
