One factor causing water quality degradation both for surface water and groundwater leachate that will Sitrate into the ground and conhmhak the groundwater. Considering that health groundwater is very important to support human life, solid waste disposal should be managed properly so that it will not disturb hydrology system in and around M disposal area. Therefore, research on the impact of the existence of final disposal to groundwater quality is urgent to be implemented. Research objectives are to identify groundwater flow pattern, to identify type and pattern of impact distribution of leachate contamination, and to review correlation ktween pollutant distances towards groundwater substance contents. Hydrogeology method was used to obtain infodon on surface hydrology, geology and hydrology of groundwater. Statistical technique was also used to obtain Con tamination Index, Evaluation Status of Water Quality and correlation of pollutant distances towards water quality content. Research muits indicated that location used for Galuga hd waste disposal has god &all catchments. Identification of general flow-pattern for North-South direction showed centralized form generating basin pattern and it is called as "Galuga groundwater basin" at 1% m above sea level elevation. Leachate was identified as the main pollutant with Pollutant Index of 180% and 200%. Result h m the calculation of Water Quality Evaluation System showed at scale 1, meaning that contamination level in the grounwater is low. It was scientifically proven with negative correlation of monitoring well distance to pollutant with content of pollutant substance in the groundwater. This research concluded that Galuga groundwater basin is permanently polluted area at the elevation level of 196 m above sea level.
