    Water quality is a crucial factor for the health of ecosystems and human well-being, especially in protected areas such as Llanganates National Park. This park is renowned for its rich biodiversity and the significance of its water resources for wildlife and local communities. In this context, assessing water quality at intake points one and two in the Novillo Pungo sector becomes essential. This research focuses on determining water quality through a combination of biological, physicochemical, and microbiological methods, emphasizing the use of macroinvertebrates as bioindicators. In the Novillo Pungo sector, 1,195 macroinvertebrate individuals were identified, and distributed across 20 families. The results for the EPT, BMWP/COL, and ABI indices showed EPT values exceeding 50%, a BMWP/COL score greater than 101, and an ABI rating above 52, indicating that the water quality at the sampled points is good, attributed to the presence of macroinvertebrates that are not tolerant to pollution. This biological diversity suggests a healthy and well-balanced aquatic ecosystem. Physicochemical and microbiological analyses provide additional information that corroborates the results obtained through macroinvertebrate evaluation. The results from the ICA–NSF indicate that the water quality, according to classification, falls within the range of good quality, with values of 76.61 and 72.69 for intake points one and two, respectively. Furthermore, among the eight parameters analyzed according to the ICA, one did not meet the permissible limits established by current environmental legislation. Although dissolved oxygen was the only parameter that did not comply with the permissible limits outlined in Table 2 of Ministerial Agreement 097-A, its results were compared with Table 3 of the regulations, demonstrating that the values are suitable for aquatic life. It can be concluded that the water quality is adequate for the implementation of an irrigation system. Additionally, the integration of these analytical methods provides a comprehensive assessment of water quality, as well as a multidirectional approach to environmental monitoring.
