Evaluación del nivel de contaminación del agua y elaboración de una propuesta de mitigación en el canal de riego Chambo-Guano, bloque 1.

Abstract

This research aimed to evaluate the contamination levels of Chambo - Guano los Chingazos Irrigation System (JURECH), block 1, which included the points of the Bocatoma and Molobog. This study was carried out in three phases: workshop, water analysis and elaboration of the mitigation plans. Descriptive statistics were used to analyze and process the data together with water analysis and mitigation plans. A workshop was held to get data and identify the main causes of water pollution and these are the use of agrochemicals and incineration of solid waste on the borders of the canal. The results of the water analysis showed that 5 out of 34 parameters are outside the permissible limits by the TULSMA book, bicarbonates with 158,5 mg/L, iron with 0,70 mg/L, floating matter 4,2 mg/L, oils and fats with <0. 1 mg/L and faecal coliforms with 2300 CFU/100mL for the Intake, on the other hand, for Molobog it was obtained in Bicarbonates with 132.6 mg/L, iron with 0.62 mg/L, floating matter 4.5 mg/L oils and fats with <0.1 mg/L and faecal coliforms with 3000 CFU/100mL. According to the Global Environmental Impact Matrix, Block 1 has a result of -0.72, which is a highly significant negative impact, so seven Impact Prevention and Mitigation Programmes were carried out. It is concluded that five parameters are outside the permissible limits which affect the agriculture of block 1 that is why the mitigation programmes were implemented.
