The study aimed to know, and get a picture of the condition of groundwater quality in the area of Ciracas Urban Sub-District, Ciracas District, East Jakarta, Indonesia. Besides, to know the groundwater in the residential area of Ciracas Sub-district, East Jakarta has been contaminated or not based on Permenkes RI's clean water quality standard. No.۴۱۶ / Menkes / per / IX / ۱۹۹۰. This is a descriptive study based on laboratory analyses. To determine groundwater samples in the study area, we used a sampling technique based on settlement density. The results of the study exhibited that the condition of ground water quality in the study area, according to the physical quality parameters, was odorless. Total dissolved solids (TDS) ranged from ۴۸۹.۱ mg L-۱ to ۲۹۸.۲ mg L-۱; turbidity ranged from ۰.۳۰ to ۴۵.۰۸ NTU. Unwelcome, temperature was ۳۰ °C, color ranged between ۴ and ۱۳ TCU. Chemical quality of iron (Fe) ranged from ۱۶۰۰ MPN / ۱۰۰ mL, while total bacterial coliform content was allowed at ۵۰ MPN / ۱۰۰ mL. This means that groundwater in Ciracas Urban Sub-District, Ciracas District, East Jakarta can not be used as a source of clean water.
