A joint method is proposed for estimating the water quality in terms of BOD and DO and identifying both unknown magnitude and discharged location of the pollution load from the noisy measurements on the BOD and DO. In order to detect the discharged load, the innovation process for the water quality states plays an important role, and the idea of pseudo-measurements is introduced to identify the magnitude of the pollutive load for both cases of the point-source and nonpoint-source loads. The joint estimation and identification method is tested by simulation studies.
