ABSTRACT
The "Espinar" stabilization lagoon is a body of wastewater that is located in the district (region of Puno), which accumulates wastewater that comes from the population of the city of Puno-Peru. The present study was carried out in January and February of 2019 in affluent and effluent wastewater. The measures of pH, water temperature, total suspended solids, electrical conductivity and salinity were evaluated. The results showed that there are significant differences between the data of the affluent and effluent samples during the periods analyzed (Krustal Wallis). The median concentrations values of the effluent for the parameters of temperature (16.60 °C), salinity (0.67 mg/L), pH (7.70), total dissolved solids (669.00 ppm) and electrical conductivity (1463.07 µs/cm), they all show significant differences. Also, the removal efficiency was calculated by the total dissolved solids (TDS) and the positive removal of 7.80% of pollutant load was found. Although these results are within the established limits, the monitoring mechanisms must be established for an adequate control of the parameters evaluated and thus, there won't be a deterioration of the environment surrounding the lagoon.
