    The present work entitled “Evaluation of the Microbiological and Physicochemical Quality of Drinking Water from Dispensers in Pharmaceutical Offices of the Human Settlement Mariscal Cáceres, District of San Juan de Lurigancho – Lima, 2019” aimed to evaluate the microbiological and physicochemical quality of drinking water from dispensers. The study was non-experimental, developed in a descriptive and cross-sectional manner, and the analysis consisted of 53 samples. The membrane filtration method was used for the microbiological analysis. The results showed that 15.1% presented values above 500 CFU/mL of heterotrophic bacteria, 24.5% exceeded the maximum permissible limits of total coliforms, 9.4% showed the presence of Escherichia coli, and 28.3% of dispensers were observed in poor condition, of which 20.8% did not meet proper hygiene standards. Meanwhile, 71.7% of dispensers were observed in good condition, but within these, 1.9% did not comply with the recommended hygiene. Regarding physicochemical parameters, two aspects did not meet the permissible limits: appearance and residual free chlorine. In conclusion, 49.1% (n = 26) did not comply, while 50.9% (n = 27) did comply with the microbiological and physicochemical quality of the water. The results were evaluated according to the Regulation on the Quality of Drinking Water for Human Consumption: D.S. No. 031-2010-SA / Directorate General of Environmental Health – Ministry of Health. Lima – Peru, 2011.
