In the present research study, the physical, chemical and bacteriological parameters of the waters of the Amazon River - Indiana district - Maynas province - Loreto region were evaluated. For this, two samplings were carried out at different times (rising and emptying). The water quality study was set at four sampling points (P1, P2, P3 and P4) located along 450 meters of the shoreline of the Indiana district. The samples collected from monitoring were taken to the Industrial Chemical Analysis laboratory of the Faculty of Chemical Engineering UNAP and to the Microbiology laboratory of the Faculty of Food Industries for their respective analyses. Relatively significant results were obtained, such as phosphate (1.1 mg/L), magnesium hardness (30.5 mg/L), dissolved oxygen (6.1 mg/L) and oils and fats (9.3 mg/L) in times of increasing exceeded the LMP according to the RCTs; In periods of empt...
