Abstract

The water quality of Sembrong River and Batu Pahat River might be affected by acid sulphate soils (ASS) which resulted from pyritic peat soils. The effect of pyrite oxidation in peat soils releases large amounts of Al and Fe and can impact nearby river water in contact with the soil. Other factors that can impact water quality comprise sediment (minerals) run - off, which is one of the main aspects that influenced the water quality in Malaysia. This research aims to characterize water quality and acidified peat soils based on the physicochemical properties (for soils and water) and geochemical elements (for soils only), analyze the effect of acidified peat soils characteristics (physicochemical properties) on water quality, correlate the effects of the geochemical elements of acidified peat soils on the physicochemical properties of water. Characterization of peat soils and water quality comprises in-situ measurements and laboratory analysis. The variables tested for water quality parameters comprise heavy metals (Al, Fe and Zn), anions (
