Resumen
La finalidad de este estudio fue determinar la variabilidad en las concentraciones de fitoplancton y coliformes
totales como indicadores de la calidad de agua en el río Milagro debido a la evidente contaminación por medio
de descargas de aguas residuales domesticas al río sin previo tratamiento. Se establecieron cuatro estaciones de
muestreo, dos en la zona rural de la ciudad de Milagro y dos en la zona urbana con incidencia de descargas de
aguas residuales municipales en los meses de junio y julio de 2018. Se identificaron las especies más
abundantes como la Flagilaria longissima, que es propia de aguas continentales con un alto contenido de
materia orgánica. Se determinó una baja biodiversidad de especies y altas concentraciones de coliformes
totales. Se concluyó que la calidad de agua del río Milagro no es apta para consumo humano ni para uso
recreacional, por lo que se propuso medidas que mejoren la calidad de agua en este cuerpo hídrico.
The objective of this study was to determine the variability in phytoplankton and total coliform concentrations as indicators of water quality in the Milagro River due to the evident pollution by means of discharges of domestic wastewater to the river without previous treatment. Four sampling stations were established, two in the rural area of the city of Milagro and two in the urban area with incidence of discharges of municipal wastewater in the months of June and July of 2018. The most abundant species were identified, such as Flagilaria longissima, which is typical of inland waters with a high content of organic matter. A low biodiversity of species and high concentrations of total coliforms were determined. It was concluded that the water quality of the Milagro river is not suitable for human consumption or for recreational use, for which measures were proposed that improve the water quality in this river.
