Caracterización de la calidad hídrica de la Microcuenca del río Guano

Abstract

It was conducted a study on the characterisation of the wáter quality of Guano River microwatershed,

located in Guano canton, belonging to Chimborazo province in order to pick enough information about the resource and potentially optimize their socio-environmental behaviour. Firstly, at the beginning of the this research, five sections of monitoring were established in the 18,8 Km of the micro-watershed of Guano river and its flow was determined by using the float method to the monitoring period from August to December 2014, also, in these points previously mentioned, it was conducted the characterisation of the water quality by using the wáter quality rate (WQI) as well as the Andean biological rate (ABI) that include the analysis and assesment of physical-chemical, microbiological, and biological parameters. As a result, it was identified a flow rate of 287,60 L/s for the monitoring period in the micro-watershed; while the wáter quality rate ABI and WQI provided these outcomes: Section 1, whose score is 76,50 which corresponds to “Good” and 67,50 corresponding to “accetable”; then section 2, has a score of 56,39, corresponding to “medium” and 27 correspondind to “suspicious”; followed by Section 3: 49,12 which correspons to “poor” and 21 corresponding to “critical”; next, point 4: 53,55 corresponding to “medium” and 31,4 corresponding to “suspicious” and finally point 5: 51,45 corresponding to “medium” and 32 corresponding to “suspicious”. It is concluded that wáter quality of the watershed of the Guano river ranges the “media” criteria with a value of 57,4% and “suspicious” with a value of 35,76% according to the WQI and ABI rates, respectively; in addition to this, the use of the Andean biological rate is helpful for studies involved to wáter resources in áreas ranging altitudes around 2000 and 4000 meters above sea level (m.a.s.l). It is recommended to submit to the appropiate environmental regulations to reduce pollution in rivers, improving the quality of life of the population.
