The people in Tuntungan Village fulfill their drinking water needs by buying drinking water from the Refill Drinking Water Depot (DAMIU). The water at the depots around Tuntungan Village is sourced from springs in the Sibolangit area, North Sumatra, where this water is distribute using tank trucks to drinking water depots in Tuntungan Village. Then it will be processed and distributed in each water depot. The drinking water treatment process at DAMIU has the potential to cause water to contain E.coli. Therefore, this research was conducted to determine whether there was E. coli in the water distributed by DAMIU in Tuntungan Village.
