The Llaviuco, Matadero, and Tomebamba rivers, originating from Cajas National Park, are crucial water sources for the city of Cuenca, supplying water for purification and supporting recreational and agricultural activities. The increase in activities has raised concerns about their impact on water quality. For this reason, a water quality assessment was conducted using the NSF-WQI Water Quality Index, which includes physical, chemical, and microbiological parameters. These parameters are: temperature, turbidity, pH, total dissolved solids, nitrates, phosphates, dissolved oxygen, biochemical oxygen demand (BOD), and fecal coliforms. The study was carried out over a two-month period, with analyses conducted at five sampling points along the three rivers. The results indicated that the water quality is generally good. The findings were compared with the limits established by the TULSMA regulation Annex 1, Table 1: Maximum permissible limits for water intended for human consumption and domestic use, which require only conventional treatment, and with previous studies. High levels of fecal coliforms were detected at sampling point 5 (Tomebamba River near Italpisos S.A.), exceeding permissible limits during the first two weeks of the study. When compared to previous studies, it was found that from point 5 onwards, this trend persists. However, the same studies confirmed that the water quality of the rivers has not shown significant changes over time.
