The main goal of this study was to see how water-soluble fractions of light crude oil from the Taq taq refinery influenced those physicochemical parameters in drinking water from the Dukan River and Sarchnar spring sources. According to statistical analysis, water quality parameters such as pH, electrical conductivity, temperature, turbidity, color, total solids, total dissolved solids, total suspended solids, ammonium, sulfide, and phosphorus have all been impacted by this crude oil when compared to controls (water resources) and drinking water quality standards. The results showed that the values of turbidity, color, ammonium, sulfide, and phosphorus in water samples that have been treated with various percent of crude oil water-soluble fractions are increased due to the high effects of crude oil on the physical and chemical characteristics of water resources (% 0 controls). According to our findings, the effect of crude oil contamination on water quality has been linked to a variety of factors.
