This study assesses temporal and spatial variations in water quality parameters within the Zarafshan River Basin using retrospective data and field measurements. Water quality indicators, including electrical conductivity (EC), total suspended solids (TSS), ammonium nitrogen (N-NH<sub>4</sub>), nitrite nitrogen (N-NO<sub>2</sub>), nitrate nitrogen (N-NO<sub>3</sub>), temperature (<i>T</i>), chemical oxygen demand (COD), dissolved oxygen (DO), and discharge, were analyzed using the Pearson's correlation coefficient and ANOVA, with the Mann–Kendall (MK) test detecting trends over time. Obtained results indicate significant seasonal effects with elevated TSS during summer, increasing sediment load and changing aquatic habitats. The strong inverse correlation (–0.89) between DO and N-NH<sub>4</sub> signifies ecological challenges particularly in low DO concentrations during summer (3.25 mg L<sup>–1</sup>). Long-term analysis identifies Navoiazot chemical factory as a major pollution hotspot. Spatial analyses based on extended sampling have revealed the Siab and Dargom canals and Samarkand City as major pollution sources of elevated N-NO<sub>2</sub> and COD, respectively.

The results showed concentrations ranging between 2 and 65 ng m<sup>−3</sup> and decreasing with distance from the former landfill. Given that the distance to other potential sources was similar in all sampling sites, the evidence found suggested that the former Lepanto landfill may contribute to the local PAH inventory.

It is easier to discover rules and obtain useful information from huge data set by the 3DV-HLM method.
