Sebaran Indikasi Air Tanah Terkontaminasi Lindi Di Sekitar Tempat Pembuangan Akhir Sampah Bukit Pinang Kota Samarinda

Abstract

The final waste disposal site (TPA) Bukit Pinang of Samarinda City applies open dumping method so that it can potentially produce leachate that can pollute the surrounding environment. This study aims to determine the distribution of groundwater contaminated leachate. We used the geoelectric method by analyzing the geological and geomorphological characteristics around the landfill to produce an alleged model of the shallow leached groundwater distribution contaminated around the landfill. The results indicated that there is an indication that shallow groundwater has been contaminated by leachate indicated by the result of measurement of the distribution of resistivity value, the distribution of chargeability value. The contamination indications are located in the northern, eastern and southern parts of the landfill with spreading pattern following the rock layer strike pattern (N 20 E) and the river flow pattern of the eastern part of the TPA.
