Objective: Analyze the water quality of two dams in Arequipa, Peru. Materials and Methods: A cross-sectional study was conducted in which the water samples of "El Pañe" and "Aguada Blanca" were evaluated, two dams located in southern Peru. The presence of bacterial growth and metals was sought. Algae samples were also collected for characterization. Samples were processed in the laboratory following national (MINSA, MINAM and SUNASS) and international (PAHO / WHO, APHA, AWWA and WEF) guidelines. Results: Eleven water samples were positive for bacterial growth. After the IMViC test, nine samples were found to be positive for coliforms. In addition, the presence of arsenic was detected in both “Aguada Blanca” and “El Pañe”, (0.027 mg / L and 0.024 mg / L, respectively). Finally, Euglenophyta sp, Bacillariophyta sp and Chlorophyte sp. Conclusion: water samples from both dams were contaminated by fecal and arsenic coliforms. Different species of algae were found, which were not toxic.
