Computerized Stratified Random Site-Selection Approaches for Design of a Ground-Water-Quality Sampling Network

摘要

The report describes approaches and computer software that can be used during the design of a ground-water-quality sampling network. The software includes several options for stratified random selection of sites. The region of interest can be any combination of one or more irregular polygons. The software can be used to randomly select sites from a single hydrogeologic or land-use setting or from several different settings. The computer program is designed to select sites from each category, one category at a time. The report first presents the theoretical discussion of various approaches for designing a ground-water-quality sampling network. The discussion is followed by a description of software that can be used for applying the approaches. The description includes application of the software to a hypothetical study region. Statistical analysis of the approaches presented in the report is described in an appendix.
