Heavy Metals of Landfill Leachate in Klotok Kediri, East Java

This study aims to determine the content of heavy metals from waste landfill leachate Klotok Kediri. Samples using leachate from the leachate treatment plant with a collection type is composite sample. Sampling point means S 07°49.017' E 111°494', S 07°49.020' E 111°492', S 07°49.023' E 111°493' and S 07°49.023' E 111°492'. Sampling was conducted in July-September 2013, in dry season. Heavy metal analysis performed using AAS. The results, found heavy metals Fe, Mn, Cu, Zn, Cr6+, Cr tot, Cd, Hg, Pb, Ni, Co, CN, As, Se and Sn. The heavy metal concentrations are respectively 2.010; 0.967; 0,040; 0,040; <0.002; <0.0269; <0.0067; <0.0002; <0.00547; 0.093; 0.047; 0.018; 0.006; 0.571 and 1.164 mg.L-1. Metal concentrations were then compared with the appropriate quality standards Decree Head of BAPEDAL No. KEP/04/BAPEDAL/09/1995, showing the only Se was beyond the quality standard. The conclusion, this study was found 15 types of metals from landfill leachate Klotok Kediri. Metal concentration have beyond the quality standard is Se, which is 1.164 mg.L-1 of 0.05 mg.L-1 was allowed, whereas the other metal concentrations are still well below the standards. This characterisation was reasonable considering the landfill was operated is >10 years old
