The thesis analyzed the evolution of the environmental parameters of the surface water of the Nanay River, as an effect related to the Construction of the Nanay Bridge and Access Viaducts, in the district of Punchana, province of Maynas. The study is quantitative of the observational, descriptive, analytical type. The information was obtained from the quarterly environmental monitoring of 2018 - 2021 expressed in the results of the physicochemical, microbiological, total metal analyzes and direct field measurements of the most important environmental parameters of the water carried out by the Construction Company Consorcio Puentes de Loreto. The physicochemical results show that in the concentration parameters of oils and fats, nitrates (NO3), hydrocarbons in surface water, their concentration levels are below the Environmental Quality Standards for water in each parameter evaluated. While for the surface water color parameter the values exceed the Environmental Quality Standard of 20.0 true color Pt/Co. scale; all of them determined by category 4 E2: rivers of the jungle, established in Supreme Decree No. 004-2017-MINAN. In the evolution of the concentration of microorganisms, mainly E. coli in surface waters report concentrations above the Environmental Quality Standard of 2000 MPN/100 ml for water, Category 4 -E2: Jungle Rivers. Regarding the concentration of total metals, values for arsenic and mercury are below the Water Quality Standard. While the evolution of the lead concentration presents concentration values that slightly exceed the Environmental Quality Standard of 0.0025mg/l. for water. In relation to direct evaluations of pH and conductivity in surface water, values within the pH range and conductivity below the Environmental Quality Standard of each parameter for category 4-E2 water are reported.
