Synopsis

Water quality is an issue that affects the health and well-being of the community. This article consolidates several investigations in the micro-basin of the Guachicos River that supplies the aqueduct for 100,000 inhabitants of the urban area of Pitalito andfive of its tributaries in the upper basin of the Magdalena River, monitoring physicochemical and biological variables with macroinvertebrates. There were 9 samples of macroinvertebrates in the period from April 2018 to August 2019, which were collected, characterized and evaluated with the methodology of BMWP/Col de Roldán. The physicochemical variables were measured according to IDEAM’s recommendations and
the following indexes were calculated: ICA, ICOTRO, ICOMO, ICOSUS and ICOMI. There are high values of ICOTRO, evidencing hypereutrophy due to leachings of fertilizers from coffee crops and discharges of residual waters, and also of ICOMO due to the presence of high values of total coliforms. 8347 macroinvertebrates were collected, the most abundant families being the Hydropsychidae with 47,17%, the Perlidae with 11,19 % and Leptophlebiidae with 7,89 % of the collection. These three families that indicate good quality waters were found in the upper and middle parts of the Guachicos River and the El Cedro Creek. The BMWP/Col values are more than 100 in the upper and middle parts of the Guachicos River and El Cedro Creek; values lower than 100 show moderately contaminated water in Aguas Negras and Caney Creek, highly contaminated in La Maralla, and in El Cedro and Guachicos River, deteriorating in quality as they flow through the settlements and crops. The results show the need to control the quality of water in the tributary streams and to continue monitoring it, both at the
main source and in the streams.
