Assessment of groundwater vulnerability to pollution in the metro downstream watershed using the sintacs method / Muhammad Farhan Adi Wibowo

Abstrak
Assessment of groundwater vulnerability in the Metro Hilir watershed is necessary because most people use well water to meet basic needs. Identification and spatial analysis are the first steps to determine the potential for groundwater pollution in the area. The SINTACS method is used to assess the intrinsic vulnerability of groundwater using the parameters of groundwater table depth effective infiltration material in the unsaturated zone soil texture type aquifer media hydraulic conductivity and slope. Data processing is carried out with the help of Geographic Information System (GIS) techniques. The weighting uses scenarios based on the hydrological conditions of the study area. The weight scenarios used are Normal Impact and Drainage/seepage . The SINTACS index results are classified at several levels of vulnerability. The high vulnerability class is spread across the east to the south side while the low vulnerability class is more dominant in the western area. The results of Sensitivity Analysis using the Map Removal technique show that in both scenarios soil texture parameters have the highest variation index value of 1.73% in the Normal Impact scenario and 2.13% in the Drainage/Seepage scenario. Parameters with high variation index values have a sensitive influence on vulnerability class values.
