Golder Associates Inc. (Golder)conducted two aquifer pumping tests and performed numeric modeling to characterize and evaluate the water-bearing properties of the Brunswick aquifer system of the Brunswick aquifer system (also known as the upper and lower Brunswick aquifers) in Glynn County, Georgia. Multi-level observation wells were utilized to evaluate possible hydraulic communication between the Brunswick aquifers and the Altamaha River due to concerns that long term pumping might adversely impact sturgeon habitat in the vicinity of Ebenezer Bend. No leakage between the Brunswick aquifers and overlying aquifers or the river was observed during the test period. A numeric model was created to estimate the long-term effects of pumping. The results of the model simulations indicated that well planned development of the upper and lower Brunswick aquifers should not significantly impact the source of subsurface recharge to the Altamaha River at Ebenezer Bend.
