Ground-water levels, 2001 - Lower Floridan aquifer

Lower Floridan Aquifer and Underlying Units in Coastal Georgia

Water levels in 10 wells were used to define groundwater conditions in the Lower Floridan aquifer and underlying units in central and southern coastal Georgia during 2001 (map and table, facing page). In this area, water in the Lower Floridan aquifer is confined and influenced mostly by pumping. Water levels in 9 of the 10 wells were within or above the normal range during 2001. The water level in one well was below normal. Water-level hydrographs for four Lower Floridan aquifer wells in coastal Georgia, (shown below) were chosen to illustrate monthly mean water levels during 1997–2001 and period-of-record water-level statistics. Water levels in all four wells declined from 1998 to mid-2000. In wells 38Q201 and 39Q024 in Chatham County, water levels were generally at or above normal during 1997–2001. Water levels dropped below normal in well 38Q201 in 2000, and in well 39Q024 during 1997 and 2000. Although the water level in well 34H391 in Glynn County declined during 1999–2000, it was within the normal range throughout 1997–2001. In well 33H188, the water level was below normal during parts of 1998–2001.
