| Summary: | <p>Landfill is a place for disposal of waste materials by burial and is method for organized waste disposal. There are many impacts that can occur when a landfill is operated such as contamination (chloride) of groundwater and wastes can come from different places such as industry, house, market, and so on which can produce chloride concentration are different. In 1992, Jatibarang landfill has been operated and is the biggest landfill in Semarang city. Everyday the wastes in Semarang which are collected to dump in Jatibarang landfill are about 3140 m3 that can produce leachates which give value of chloride concentration is 2612,98mg/L. In order to understand the nature of chloride plume and to understand chloride loads to the river (near Jatibarang landfill) from Jatibarang landfill, study of analytical model 1-D and mass balance approach are carried out to estimate chloride plume and chloride loads to the river. Finally, the result of chloride plume map and amount of chloride loads from landfill can provide some understanding in order to support the groundwater and surface water management by the community and different government agencies to protect water resources.</p>
