Description:
Methods commonly used to delineate protection zones for water-supply wells are often not directly applicable for springs. This investigation focuses on characterization of the hydrogeologic setting using hydrogeologic mapping methods to identify geologic and hydrologic features that control groundwater 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 constraints on ground-water flow and protective zones 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 information required for reliable and practicable protection zone delineation. This Project Summary was developed by EPA's National Risk Management Research Laboratory's Subsurface Protection and Remediation Division, Ada, OK, to announce key findings of the research project that is fully documented in a separate report of the same title.
