Description:
The research program was conducted to develop statistically acceptable, experimentally determined maximum holding times (MHT) from quantitative, legally defensible data acquired from representative real-world samples. Ten National Pollutant Discharge Elimination System (NPDES) and two Safe Drinking Water Act (SDWA) compliance parameters were studied in a total of 18 experiments. Experimental results were compared to EPA-proposed, recommended, or required MHT values. Large volumes of samples were collected from three different water sources and used for the experimental analyses of each study parameter. The development of a statistical protocol to specify experimentally determined MHTs included statistical tests to: choose the best model (zero or first order), evaluate the lack of linear fit for the model, and calculate MHTs and the 90-percent lower confidence level of the calculated MHT.
