【 摘 要 】

This study aims to determine the quality of groundwater in densely populated areas in the Pasar Minggu district, which focuses on examination of Escherichia coli bacteria as biological parameters. E.coli analysis was conducted in 3 sub-districtin the Pasar Minggu district, South Jakarta (106° 45′0″E - 6° 15′40″S), which included Pejaten Barat, Jati Padang and Kebagusan sub-district based on topography. The method used is Most Probable Number (MPN), referring to SNI 01-2332.1-2006. The results showed that the presence of E. coli in the highest groundwater ranged from 1100 MPN/100 ml to > 1100 MPN/100 ml, present in Pejaten Barat sub-district (06° 16′39 "S-106° 49′48" E) whereas the lowest number ranged from 11.5 MPN/100 ml to 23 MPN/100 ml occurred in Jati Padang sub-district (06° 17′6 "S - 106° 49′48" E).The correlation test results show that the amount of E.coli in ground water is affected by the distance of the septic tank to the groundwater well. The amount of E.coli contained in groundwater is also increasing, 1100 MPN/100 ml in groundwater samples at15 m depth. This study provides information that topography and water flow affect the amount of E. coli.
