Determination of coliform bacteria sheet on water well in Bukittinggi City

Abstract

Aim: The aim of the study was to know the quality of drill water which is close to the source of high pollution in Bukittinggi City that is suitable for public consumption. Materials and Methods: Using most probable number (MPN) and total plate count (TPC) method were used. Results and Discussion: The number of MPN >2400 bacteria/100 ml in sample A, 150 bacteria/100 ml in sample B, and >2400 bacteria/100 ml in sample C. As for TPC calculation result obtained 3752 x 102 coliform/ml in sample A, 4414 x 102 coliform/ml in sample B, and 5941 x 102 coliform/ml in sample C. Conclusion: Drilling water near the source of high pollution in Bukittinggi City is contaminated with coliform bacteria. Drilling water near the source of high pollution in Bukittinggi City is not feasible to be consumed when compared to good quality condition according to Ministry of Health Republic of Indonesia 2010 and Indonesian National Standard (SNI) number 01-3553-2006.
