Abstract

This research was conducted at Pasir Impun Landfill Site which had an unperfect sanitary landfill system, so that the groundwater contamination occurred in the surroundings area. In order to minimize the spreading of leachate as natural, basement rock properties of landfill site could be an important factor. Generally, the basement rock of Pasir Impun Landfill Site had a good geological characteristic, eventhough there was a poor value of hydraulic conductivity between 10-4 - 10-5 cm/sec (>10-7 cm/sec; minimum value for a good landfill site). The good basement rock properties of Pasir Impun Landfill Site were (i) the basement rock had a deep groundwater table, (ii) a highly clay content in the basement rock which caused a rising retardation factor. Procentage of clay mineral (kaolinite) in the basement rock of this landfill site could be 87,22 %, with the value of retardation factor was 2,63. On the other side, the poor value of dispersion at the Pasir Impun Landfill Site showed that natural attenuation did not occure yet intensively. So, it could be predicted for 10 years later that the leachate plume will bigger than now, but still in 200 meter radius of leachate spreading.

Abstract

Sustainability of production of bottled drinking water is highly dependent and influenced by the condition of the recharge zone. Thus, knowledge and understanding of local conditions and the behavior of groundwater recharge to the springs is required. To get a decent source of water produced and minimize the impact can inflict negative, then P.T. Tirta Investama implemented several stages such as literature study, identifying the area, a preliminary survey, detail survey, EIA studies, the production (construction and installation), and recharge area study at least one year. Protection of water resources taken from the aquifer is not used by people around in general (aquifers) as well as against the source of water which is generally utilized by the population (unconfined aquifer) translated in the construction of a well borehole. Meanwhile, study catchment areas become the crucial factor in the management of groundwater, natural feedback input is one of the factors associated with the process of infiltration.From this study obtained distribution of the origin of groundwater (recharge) to the water that comes out (discharge) and the layers that tend vulnerable to groundwater contamination. Studies recharge area for a minimum of one year is a very important study as sustainable groundwater resource management efforts in order water balance in a region.
