Evaluation of groundwater quality in a landfill using resist-ivity survey

Abstract EN

This paper describes the groundwater quality at Seri Petaling Landfill located in the state of Selangor, Malaysia.

Electrical resistivity imaging survey line was conducted on the top of the landfill.

Hydrogeological and hydrochemical studies were also carried out at the site.

Three boreholes drilled in the upstream, down stream, and within the landfill itself represent-ed the groundwater.

They are AH1, AH2, and AH3 respectively.

Total dissolved solids distribution were estimated and conducted on the same resistivity line.

The groundwater aquifer was determined to be unconfined.

The top of the aquifer is covered with dry superficial layer and underlined with the bedrock of Kenny Hill Formation.

The total dissolved solids (TDS) represented by Na+, K+, Ca++, Mg++, Cl-, SO4 --, and NO- 3 ions were estimated to be more than 4000 mS/cm at a depth of about 16 m and a distance of 190 m along the resistivity survey line.

The groundwater was determined as unfit for domestic purposes.
