    The objective of this study is to characterize the physical-chemical and bacteriological parameters of the waters of Laguna de Langos, located in the Guano Canton of the Province of Chimborazo, since there are no studies on the parameters of this lagoon and it is a problem of type sanitary for the inhabitants and tourists who visit it. A descriptive and exploratory study was proposed, where the main parameters, physical, chemical and bacteriological were analyzed following the NTE INEN 1105 Standards for sampling and microbiological water examination, obtaining the following results: temperature (16.01 ° C), color (Colorless), odor (Unpleasant), pH (7.14), conductivity (1913 uS / cm), Dissolved Total Solids (975 mg / L), Turbidity (5.32 UTN), sulfates (918.4 mg / L), nitrates (0.44 mg) / L), nitrites (0.0046 mg / L), alkalinity (260 mg / L), Ammonia (0.48 mg / L), Escherichia coli count (4.3 CFU / mL), total coliform count (318 CFU / mL), total aerobic count (864 CFU / mL). Which in comparison with the Environmental Quality and Resources: Water Standard, 45% of parameters are outside the allowed limit values and it was determined that the water is not safe for any of the uses specified in this norm. Also, we identified 9 bacterial strains and their antibiotic susceptibility patterns, Escherichia coli (Imipenem), Enterobacter agglomerans (Ofloxacin), Enterobacter sakazakii (Cefotaxime), Klebsiella pneumoniae (Imipenem), Klebsiella oxytoca (Cefotaxime), Klebsiella ozaenae (Cefotaxime), Citrobacter freundii (Cefotaxime), Proteus vulgaris (Imipenem) and Serratia liquefaciens (Cefotaxime). The antibiotics that are in parentheses are those that presented greater sensitivity each bacterial strain. In conclusion, the water in the lagoon represents a risk to health, both for the population living in its surroundings and for visitors.
