Statistical and economic considerations for improving regulatory water quality monitoring networks
The assignment of sampling frequencies in regulatory water quality monitoring networks has often been performed with little or no statistical or cost-effectiveness analysis. The research effort described here has attempted to address this problem through the development of appropriate statistical and economic analysis tools which might be applied by regulatory agencies. A technique is presented for predicting confidence interval widths about annual means or annual geometric means for water quality constituents while considering (1) serial correlation and (2) seasonal variation of the quality ...
