“…In this way, water quality assessing through routine and costly analyzes such as physical-chemical and microbiological, only Certainly the macroinvertebrates as indicators alternative are adequate to measure the mountain springs water quality (Callisto et al, 2023;Galdean et al, 2001;Mimeche et al, 2019;Ramírez Villalobos et al, 2015). They are used today by the ease collecting of the samples (Gamboa et al, 2008;García-Barreras et al, 2023) and, adaptability of them to environmental changes in ecosystems (Mancilla-Villa et al, 2022;Terneus et al, 2012) product of the anthropogenic activities impacts on the ground (Hofstede, 2001;Patiño et al, 2021). The objective of this work was to determine the water quality of common use mountain springs through the biological index FBI-ANIMAS similar to FBI-PR, taking into account aquatic insect communities, but adjusting tolerance values.…”
