Characterization and Toxicity Study of Leachate from Closed Landfills in Selangor

Razi Ikhwan Md Rashid, Mohd Zikri Ibrahim, Mohd Azwat Abdullah, Ahmad Razali Ishak

Abstract

Objective: The main objective of this study was to characterize the physicochemical characteristics of the closed landfill of Sungai Kembong and Ampar Tenang in Kajang, Selangor. The efficiency of leachate treatment was also evaluated. In addi- tion, acute toxicity of the leachate effluent were tested using Syprinuscarpio species.

Method: The physicochemical parameters of leachate were determined according to APHA standard methods. The acute toxicity was conducted according to the OECD Guideline.

Result: The leachate from both landfill are categorized as stabilized landfill leachate. The treatment manage to significantly decrease the toxicity, BOD, COD and NH3N concentration but the final concentration still above the allowable standard limit.

Conclusion: Biological treatment is not sufficient to reduce the pollutants level below the discharge standard and require further additional treatment. However, the initiative to install the leachate treatment facility to the former open dumping site are commendable.

Keywords: Leachate, closed landfill, toxicity
