Producing high quality water from potentially contaminated supplies is made difficult by the high cost of measuring the wide range of chemical, biological, and physical parameters of concern. This article describes a study conducted at Water Factory 21 in Orange County, Calif., to identify chemical indicators that could be measured relatively inexpensively and used as surrogates for monitoring treatment process efficiency. Various collective parameters (e.g., total organic carbon, chemical oxygen demand, and electroconductivity) and individual contaminants (e.g., chloroform, barium, and copper) were evaluated.
