According to the World Health Organization (WHO), in countries wheremost population have not been utilized the safe water supply or the polluted water with microbialpollution, people have risked with many kind of diseases including intestinal diseases. Therefore, theassessment of the water quality, especially on microbial contamination level in drinking water is verynecessary. This paper presents the observation results on coliform density in drinking water in differentdistricts in Hanoi city during the period from 2015 to 2017. The results show that most of drinking watersamples from tap water in Hanoi are not contaminated by Coliforms. However, microbial contaminationwas found for well water (at Gia Lam, Tu Liem and Thuong Tin ) with high total Coliforms and E.colidensities exceeded the permissible limit of the QCVN 02:2009/BYT, column I. The results revealed theneed for regular monitoring of drinking water, especially water from household well
