For this, the physical-chemical analysis was first determined with the Canadian water quality index method (ICA CANADA); at three points established according to their characteristics and anthropic activities, corresponding to the Illagua community (P1), Ignacio Flores Parish (P2) and Belisario Quevedo (P3). In a period of three weeks between the months of May and June, samplings were carried out to analyze the physicochemical parameters. As a result of the study of the 9 selected parameters (pH, temperature, DO, electrical conductivity, nitrates, chromium, COD, calcium and magnesium), it was observed that the water quality index (ICA) in the first two points its quality is good and in the last sampling point it is regular, likewise each parameter was related to the maximum permissible limits of the TULSMA standard of the Ministerial Agreement 097 A, for aquatic and wildlife life and irrigation for agriculture. For macroinvertebrates, a total of 856 individuals of 12 different species were obtained. Where the most abundant classes correspond to OLIGOCHAETA and INSECTA, these individuals were evaluated using the Biological Monitoring Working Party (BMWP), Andean Biotic Index (ABI), Ephemeroptera, Plecoptera, Triichoptera (EPT) and Shannon Weaver methods. According to the BMWP/col index, the quality of the river varies between doubtful and critical, likewise the ABI and EPT indices released a result from fair to bad, being classified as low diversity in the Shannon Weaver index with values between 1 and 2. Then Having carried out these analyzes, an Ishikawa diagram was generated, where the different causes and effects that alter the river in a negative way were determined, finally a table of proposals was made that focused on the most important aspects that contaminate the river, being These are the agricultural and livestock activities and the waste residues that exist in the adjacent areas of the water resource. |
