Abstract

Groundwater is the water resources necessary for living things and the most desirable human. Groundwater needs to increase as the population increase. One example is in the Alluvial Plain of Semarang. To supply water necessary, the population use a tap of aquifer shallow wells. Shallow aquifer vulnerable to contamination due to the effect of shallow depth and human activities. Therefore there is a needed to conduct for research on the groundwater vulnerability due to contamination. GOD is the system to determine of value groundwater vulnerability due to contamination. The parameters used are the type of aquifer (G), type of lithology aquitard (O), and the depth to groundwater table (D). These three parameters derived from resistivity data and hydrogeology data. The results of the analysis by this method has three levels of vulnerability of groundwater due to contamination the area of the vulnerability of low, moderate, and high. So it is recommended that the analysis can be made of the green open area to reduce contamination and groundwater catchment area is formed, and restrict the activities to achieve economic gains and reduce the danger of environmental contamination.

Abstract

emarang lowland-alluvial area is in the state of salt water intrusion, that has a direct impact to the groundwater quality. Groundwater quality is not only triggered by water level decreasing factors due to the groundwater exploitation,but also by the factor of lithology and aquifer condition. The purpose of this research is to know the resistivity rocks value, the value of groundwater quality, and to analyze the distribution of the estimated area that has been instuited by salt water. The result of processed data with Progress 3.0 is in the form of resistivity value which is correlated with groundwater quality testing value with salinity, electrical conductivity, dissolved oxygen, andpH parameters. Based on the geo-resistivity and groundwater geochemical data shows that there is intrusion salt water distribution area which occur in Trimulyo area with the resistivity value of 0,27 Ωm as the indicator of salinity and groundwater quality value parameters which show the salinity value of 3.600 mg/L, electrical conductivity of 6.370 μS/cm, dissolved oxygen of 0,8 ppm, and pH 7,7.
