Water levels measured in 15 wells were used to define conditions in the surficial aquifer system. Groundwater in the surficial aquifer system typically is in contact with the atmosphere (referred to as an unconfined or water-table aquifer), but locally, especially in coastal Georgia, the water may be under pressure exerted by overlying sediments or rocks (referred to as a confined aquifer). Where unconfined, water levels change quickly in response to recharge and discharge. Consequently, hydrographs from these wells show a strong relation to climatic fluctuations. In parts of coastal Georgia the surficial aquifer system is used as a source of irrigation supply and shows a response to local pumping.

Well Locations with Ten Year Trend Icons
Arrow icons represent upward or downward water level trend. Calculations based on last 10 years of data.
Dot icon represents trend slope less than 0.01 ft/yr. or less than 100 data points from the last 10yrs. of data.
Split color icons represent wells with graphs.
