It will be prolonged that the Upamayo river is contaminated due to the effluent from the oxidation pond of the Daniel Hernández district of the Tayacaja province, since the quality standards exceed the parameters of pH, fecal coliforms, Escherichia coli, TSS and salinity for water intended for animal drinking. Likewise, they exceed the environmental quality standards (ECA) in pH, Escherichia coli, TSS and salinity for unrestricted irrigation waters. In that, the mitigation alternatives to this problem will be the reduction of the discharge mouth of the oxidation pond, optimization of disinfection before the effluent is discharged, the application of projects to fines to increase the flow of the Upamayo river, the inclusion of a phytoremediation system within the ponds of oxidation or the execution of a public investment project for the construction of a large-scale wastewater treatment ...

The objective of this article is to restore soil contaminated by dumps through the microorganism Bacillus cereus. The methodology includes 5 samples of soils contaminated by dumps, where experiments will be carried out, which will be mutually contrasted and it will be determined if the bioremediation microorganism is efficient or not for the restoration of contaminated soil. The results show that a bad practice in solid waste management are illegal dumps that cause soil contamination, this problem afflicts the district of Pampas, specifically in the San Cristóbal hill, in the investigation a sample of the hill was analyzed San Cristóbal where the initial pH, temperature and texture is 7.5 pH, 22 C ° and clayey, respectively, through the remediation method with the Bacillus cereus bacterium, the pH changes and drops to 6.6 pH, the temperature also changes to 21 ° and the texture chang...
