Groundwater Quality Assessment in Jakarta Capital Region for the Safe Drinking Water

摘要

This study aims to determine the quality of Jakarta Capital Region's groundwater and its recommendation based on the standards set by the Indonesian government especially The Health Minister Decree No. 907 / Menkes / SK / VII / 2002 about The Drinking Water Monitoring. The study activity uses the data that carried out by Geological Agency, Ministry of Energy and Mineral Resources, Indonesia from March to April 2015. The methods used in this study are direct observation and hydrogeological measurement to measure physics and chemistry parameters. The results show that most places in the study area have the low quality of groundwater which is below the drinking water quality standards according to the government. However, at the unconfined aquifer (depth of 0-40 meters), the certain areas such as in the Kramat Jati, Halim Perdana Kusuma, Tongkol-Pademangan, and Duren sawit are still relatively safe for consumption as drinking water. In addition, the confined aquifer (deptii> 40 meters) such as in the area of Cibubur, Pasar Rebo, and Jagakarsa are considered safe for consumption as drinking water. This study is expected to be used as a benchmark for researchers, especially academics in the region in order to maintain the sustainable groundwater resources in the area.
