Potable ground water in the Naples area along the coastal ridge of western Collier County, Florida, is available from two principal sources--the water-table zone and the pumped zone, both within the surficial aquifer. The primary source of public supply is from the pumped zone, locally known as the Coastal Ridge aquifer. Water levels in wells in the pumped zone respond rapidly to pumpage and usually indicate a cone of depression in most of the highly urbanized Naples area. The cone of depression caused by pumpage has created significant water-level differences between the water-table zone and pumped zone. Water-level differences in the two zones from 1975 to 1979 frequently exceed 10 feet. The maps have been drawn to be representative of hydrologic conditions in both zones for the wet and dry seasons from 1975-79. (USGS)
