Description:
Ground-water monitoring is one of many management options for Wellhead Protection Program implementation. round-water parameters are monitored (1) to assess source-control measures, (2) to monitor compliance with drinking water standards at sites other then the wellhead, and (3) to provide advance warning of contaminants in ground water. ooperative research was conducted with five municipalities to develop long-term monitoring program for their existing wellhead protection areas. he product of this research is a Project Report which contains a methodology for planning and implementing a wellhead protection monitoring program. he methodology emphasizes source assessment, correct wellhead protection area delineation, and hydrogeologic characterization. ive case studies are included in the document to exemplify the monitoring methodology for different hydrogeologic and contaminant source settings. he five case study research sites include Stevens Point, Wisconsin; Littleton, MA; Sioux Falls, SD; Dover, New Hampshire; and Springfield, MO. he documentemphasizes a multi-disciplinary approach for hydrogeologic characterization, wellhead protection area delineation, and flowpath assessment. ydrogeologic characterization techniques include: well installation, water quality sampling and assessment, geologic and structural-control mapping,, aquifer testing, dye tracing, borehole geophysics, analytical solutions, and ground-water flow modeling.
