The goal of this webcast series is to emphasize the importance of sound data for planning purposes at wastewater treatment plants, particularly those that are faced with upcoming effluent nutrient regulations, or stricter regulations. An interactive workbook has been prepared for members in question-and-answer format to allow plants to define how much sampling is enough. This tool helps to define how many days of sampling are sufficient, where samples should be taken, and what parameters should be analyzed. The results of the workbook often are additional to prescribed permit requirements, although some samples and parameters would correspond with mandatory permit requirements. A number of case studies will be discussed to exemplify sound sampling practices. The potential for on-line instrumentation and impacts on laboratory practices will also be discussed.
