The dependence of the auto‐refining process of the Lavin River, Iran, on the types and the quality of chemicals and organic compounds discharged into the river as the wastewater generated by sugar beet industries located nearby, was investigated. For the purposes of this study, sampling was performed utilizing a design‐based static stationary sampling pattern. Several study stations were selected around the waste discharge location in order to perform sampling and field investigations during three sampling campaigns within two years. Numerous analytical procedures were performed on the samples for water quality assessment. In addition, a recently developed dispersive liquid‐liquid microextraction method was employed as a more sensitive sample preparation method for the instrumental chemical analysis, in order to enhance the limits of detection of the trace biocide residues. The evaluation and validation of the data acquired from the field observations, sampling, and river water quality assessment was performed using statistical methods. The obtained results showed that the auto‐refining process is an exclusive river remediation factor that indicates a variety of auto‐refining capacities for various chemical, physical and biological contaminating parameters affecting the water quality of the Lavin River.
