Abstract

This preliminary study represents the study on hydrogeochemical of caves drip water throughout Peninsular Malaysia. All samples were analysed for pH, Total Dissolved Solid (TDS), Dissolved Oxygen (DO), Conductivity, cation and anion. Despite local hydrological and geological differences among sampling sites, the monitoring revealed significant synchronous intersite variations that related to rainfall variation and control the volume of water input. The constant hydraulic pressure is expected in karst system as a result of moist condition of tropical region and rainfall throughout the year. Drip sites were classified into to two classifications which are seepages flow and seasonal flow. A simplified conceptual model that show the physical and hydrogeochemical evolution of karst system is proposed. In generally, drip water consists of Ca, Mg and HCO3 as dominant elements. The source rock deduction analyses strongly suggest that the hydrogeochemical properties of drip water are originated from carbonate weathering. SIcalcite determined that drip water is saturated with calcite. The water rock interaction process involves in the karst system are dissolution, dilution, ionic exchange and prior calcite precipitation that lead to saturated SIcalcite index. Each of drip possesses a unique hydrogeochemistry characteristic, must be significant related to the host rock properties, flow path characteristic, fracture system behavior and volume of water input.
