Study of Leachate Penetration in Shallow Groundwater Around Jabon Landfill Sidoarjo

Abstract

This study was conducted at Jabon Landfill located in Jabon District, Sidoarjo. Jabon Landfill has been operating since 2003 with the Controlled Landfill system. Laboratory test results of samples taken at 18 sampling points in the east, south and west zones of the landfill for Total Dissolved Solid (TDS), Turbidity, Manganese (Mn) and Chloride (Cl⁻) parameters showed that they were higher than the quality standards except Iron (Fe). According to the groundwater elevation, contaminants were dispersed towards the east and south of the Landfill. Leachate pollutant index was 7.70 which means it was moderately polluted. A well was used as a source of clean water but the well water has a quality status of moderately polluted and lightly polluted. The distance and depth of initial groundwater have a significant effect on the status of water quality.
