Abstract

Multiple regression analyses of water quality survey data produced a large number of statistically significant prediction equations with similar standard errors of estimate. The equations developed were not sensitive to changes in the independent variables or to omission of some readings in the input data sets. Authors conclude that input data from several years are necessary for equation development and that multiple regression techniques for water quality estimation should be used with caution. Nevertheless, by judiciously selecting appropriate equations it is possible to estimate effects of wastewater loadings on lake water chemistry.
