This study determined whether the drinking water in urban areas in the municipality of Cundinamarca Bojacá, met the physical, chemical and microbiological criteria established in Resolution 2115 of 2007 To this end, there were two samples from different parts of the distribution system, natural sources and storage tanks at home. Photometric, electrometric and volume methods were used in the respective physical and chemical analysis; additionally for microbiological parameters was used the membrane filtration technique. The results showed that most samples did not meet the minimum permissible value of free residual chlorine, therefore, according to the Risk Index Water Quality Water for human consumption (IRCA), are classified as non-unfit for human consumption. However, other microbiological parameters were met including the parameters set out in Resolution 2115 of 2007. Water quality must be maintained throughout the distribution system. Therefore, in addition to carrying out the treatment processes, the service provider must keep a strict control of the factors that may affect water quality.
