Metallic contaminants in Andean water resources influenced by mining activities poses risks to aquatic ecosystems and a challenge regulatory agencies responsible for environmental compliance. In this study, the Ecological Risk Assessment (ERA) framework was adapted assess dissolved heavy metal concentrations at 283 surface monitoring stations near six projects during dry wet seasons. Reports from OEFA-Peru on Early Environmental (EEA) were used apply various criteria non-parametric statistical tests. They included ecological, ecotoxicological, chemical, factors. The main goal of research identify, analyze, characterize, compare present different trophic levels. These levels categorized as T1 (Microalgae), T2 (Zooplankton Benthic invertebrates), T3 (Fish). Individual risk (IR) estimated using quotient model, while total (TR) assessed additive probability rule. Rainbow trout (Oncorhynchus mykiss), representing level T3, showed highest sensitivity Fe Cu. Statistical tests ranked IR Fe>Cu>Zn>Mn>Pb (p<0.01). TR more prevalent season compared Notably, around 50% (n=142) classified high risk, 9% (n=13) extremely high-risk values Cu Fe. ERA demonstrated great effectiveness identifying critical points contamination under influence. However, specialized studies are suggested that allow sources pollution be associated with specific actions.
