Research has been carried out which aims to determine the quality of drinking water in refill drinking water in Lala Village, Namlea District, Buru Regency. This type of research is quantitative descriptive with a laboratory experimental approach which aims to obtain an overview of the content of Escherichia coli and calcium carbonate (CaCO3) bacteria in refill drinking water. Based on the results of the study, it was found that for the biological quality of drinking water samples at the refill drinking water depot in Lala Village there were two polluted refill drinking water depots and were detected to have an average total Escherichia coli in sample I was 5/100 ml and sample II 5/100 ml. As for the chemical quality, it shows that all drinking water samples consist of 4 samples, the hardness as CaCO3 is still within the normal limit, namely 200.927 to 285.007 mg / l. So it can be concluded that all refill drinking water depots in Lala Village are safe for CaCO3 hardness, while for the biological quality of depot I and depot II are not suitable for consumption.
