title: [Bacteriological quality of drinking water in the City of Merida, Mexico].
abstract: With the aim of knowing the microbiological quality of drinking water in Merida, Yucatan, 383 paired samples of drinking water (two per house) were studied. Three hundred sixty four (95%) city water system samples and 283 (73.89%) tap water samples met the microbiological standards for drinking water. It was concluded that microbiological quality of drinking water from the city water system is satisfactory, except for the water system district Merida III, which has a significant aerobic plate count contamination level (21.7% of the samples). Domestic storage systems preserve water quality, with the exception of district Merida I, which has the highest level of contamination (4.8% of the samples) possibly from sewage water and fecal sources.
