Desarrollo de un sistema de monitoreo comunitario de calidad del agua en la Mancomunidad del Chocó Andino.

Abstract

The objective of this titling project was to develop a community water quality monitoring system in selected sections of the course of the Alambi, Pachijal, Chirape and Mashpi rivers, located in the Mancomunidad del Chocó Andino (MCA). Based on technical-operational knowledge, it contributed to the strengthening of local capacities to monitor the water quality of these rivers and therefore the result of the implementation of public policies and private initiatives. In a first stage, theoretical and practical trainings were carried out for the team made up of the MCA. The topics addressed were the fundamentals of the sampling and analysis of water quality parameters, as well as the causes of its contamination. In addition, they were instructed on the use of in situ measurement equipment, recommended methods for the conservation of samples and requirements for community monitoring of rivers. In the second stage, a baseline of water quality in the four rivers was drawn up, after determining the monitoring points. The parameters that were determined: temperature, pH, electrical conductivity (EC), turbidity, dissolved oxygen (DO) and total dissolved solids (TDS). In addition, the following were analyzed: metals, chemical oxygen demand (COD), biological oxygen demand (BOD5), nutrients and fecal coliforms (CF). In the third stage, a virtual manual was developed which describes the training topics along with links of interest. The steps to be followed for the sampling and measurement of parameters in situ and information for the interpretation of the data obtained from community monitoring are indicated. This resource will be a consultation document for those in charge of monitoring in the Commonwealth. Finally, the results were shared with the local team and the current president of the MCA.
