The investigation focuses on characterization of the hydrogeologic setting using hydrogeologic mapping methods to identify geologic and hydrologic features that control ground-water flow to springs to aid in delineating protection zones. These techniques were applied at two public-supply springs selected to represent diverse geologic settings. One spring discharges from a fractured carbonate system and one from a clastic-rock aquifer. Results of this investigation allowed development of the conceptual model for site hydrology and identification of potential controls on ground-water flow at each site. The report discusses results from these case studies and a general methodology for applying these techniques to delineation of protection zones around springs. The hydrogeologic conceptual model resulting from the use of these tools provides the framework for identifying significant data gaps and implementing studies to obtain any additional informatiuon required for reliable and practicable protection zone delineation.
