Prepared by the Task Committee on the State of the Art in Long-Term Groundwater Monitoring Design of the Environmental and Water Resources Institute of ASCE.

This report contains detailed descriptions of the leading methodologies for groundwater monitoring network designs and guidance for the implementation in a variety of field conditions. Addressing the needs of analysts and practitioners, this report reviews the methods available for for the design of groundwater monitoring networks. The report examines the analytical and quantitative procedures that identify optimal sampling locations and times so that representative groundwater quality data—essential in the development of groundwater management strategies—can be obtained. 

Topics include:

•  the objectives of long-term groundwater monitoring,
•  data requirements in groundwater monitoring network design,
•  case studies, and
•  future research and technology transfer needs in groundwater hydrology and hydrogeology.
