Background The Ichu River serves as the primary water source for urban and agricultural use industrial operations, but anthropogenic pollution has a serious negative impact on its quality. Methods investigation measured quality health-related risks by analyzing physicochemical parameters, heavy metals, microbial pollutants at eight sampling points, site 1 (S1) through (S8). Results research data showed that worsened progressively from upstream to downstream locations such turbidity, TDS, conductivity, BOD levels increased. Oil oxygen depletion arose reduction in dissolved 6.3 4.5 mg/L different sites (S1 S8). Heavy metals (As, Pb, Cd, Cr) samples exceeded standards established World Health Organization (WHO) because of mining wastewater local discharge. presence excessive Escherichia coli (E. coli) total coliforms tests proved was severely contaminated fecal matter. Principal Component Analysis exist with organic load main sources decline, indicators were found establish powerful relationships depleted levels. Conclusion severe contamination this study justify immediate control measures, treatment enforcement, sustainable watershed management practices. Urgent action is necessary vital parameters surpass set WHO (United States Environmental Protection Agency (USEPA) avoid enduring environmental damage health problems. This demonstrates value continuing assessments while enforcing policies raising public awareness improve River.
