- Abstract
The article presents a study which evaluates long-term trends in total phosphorus (TP) concentrations using flow-adjusted TP concentration in the Illinois River of Oklahoma. The study uses self-reporting data from wastewater treatment plants and flow-adjusted estimate for in-stream P concentration. The study reveals the difficulty in quantifying long-term trends in TP concentrations. It also demonstrates the need to use statistical methods in detecting changes in long-term water quality data sets and identify change point and nonlinear responses.
