Determinación de puntos de muestreo para el estudio de la calidad de agua de la acequia Pumamaqui

Abstract

The objective of our Grade Work is to take sample points through the topographic research and make water Quality Analysis of the Pumamaqui irrigation channel that has an extension about 12 Km, and it is located in the Pesillo community, Cayambe City, Pichincha Province. During our research through the channel, we found critical points to analyze; it gave us 16 important sites to study, starting from La Chimba River to the Imbabura Province limits. The water samples were taken by January 2019, and they were analyzed with Physic and Chemical parameters like PH, temperature, turbidity, dissolved oxygen, electrical conductivity, all solids, Biochemical Oxygen demand (BOD) and Chemical Oxygen Demand (COD), and a fecal coliforms microbiological analysis. Once we obtained the laboratory results, we proceeded with the data interpretation, were we were able to confirm that the Pumamaqui irrigation channel is not good for human consume and it could only be used for agriculture environments or for short sites irrigation due the high level of fecal coliforms in the water. The BOD and the dissolved oxygen surpass the standard, and it confirms that the water channel has an organic contamination level. In addition, the solid’s value are in high levels. We compared these results with the maximum levels permitted established in the TULSMA’s Environmental Quality and Effluent Discharge Standard: Water Resource BOOK VI APPENDIX 1.
