Abstract This work evaluates the effect of mining activity on sediments and water from the Lunar and Cumunni lagoons, in Puno. Surface waters were evaluated in the dry season and rainy season in 2018. The physical-chemical analysis included: pH, conductivity, DO, BOD₅, COD, hardness, chlorides and suspended solids. It also included metáis (As, Cd, Cu, Fe, Hg, Ni, Pb and Zn) in water and sediments. The results were compared with Peruvian and Canadian environmental quality standards and reference levéis for the United States of America. The results show valúes outside the established norms, mainly acid pH and hard water. The metáis Cd, Ni, Pb, Fe and Zn also exceed the limits of the standards. The concentration of Hg in sediments reached high valúes of 20.13 and 33.32 mg / Kg in the rainy and dry season respectively.

Keywords : Pollution; lagoons; mining; mercury; sediments.
