Landmeyer, J.E. 1994. Description and application of capture zone delineation for a wellfield at Hilton Head Island, South Carolina. U.S. Geological Survey, Water-Resources Investigations Report 94-4012, 33 p.

Capture zone delineation for coastal wells was estimated using a combination of models designed to evaluate groundwater flow. Both analytical and numeric models indicate the current 100 foot radius of protection around a well underestimates the groundwater capture zone.


Landmeyer, J.E. and P.A.Stone. 1995. Radiocarbon and δ13C values related to ground-water recharge and mixing. Ground Water, 33:227-234.

Measurements taken during this study and others found radiocarbon and δ13C values varied among different locations on Hilton Head Island, South Carolina. The differences suggest these types of data may be useful indicators of groundwater mixing from different sources and for determining recharge-discharge patterns.


Landmeyer, J.E. and P.M. Bradley. 1998. Hydrologic and water-chemistry data from the cretaceous-aquifers test well (BFT-2055), Beaufort County, South Carolina. Southeastern Geology, 37:141-148.

A test well was installed to evaluate the potential of the Cretaceous aquifer beneath Hilton Head Island, South Carolina as a groundwater source. Results from the test showed the water to be non-potable.


Mack, J.B. 1994. Field Investigation of Saltwater Intrusion – Cumberland Island, Georgia. Masters Thesis. Georgia State University, Atlanta. 103 p.

The Pliocene-Miocene confined aquifer beneath the southern end of Cumberland Island, Georgia was investigated for saltwater intrusion. Measurements of hydraulic head were taken every half hour for 3 days in order to construct potentiometric maps displaying groundwater flow orientation at various times of the tidal cycle. The dominant direction of flow to the west appears to serve as a barrier to saltwater intrusion.

A National Park Service report presenting data from a Masters thesis focused on salt- water intrusion (see entry #81).
