The processing of amang or tin-tailing in Malaysia has been an important on going radiological as well as environmental issues in Malaysia. Large volume of water is used in the extraction of valuable minerals from amang and it has become a potential source of environmental pollution depending on how the water is managed. An environmental impact study of one such amang processing plant using the open water management system was conducted. Four sampling locations were identified; amang effluent containment pond - before the water is discharge into the river (C1), effluent discharge point - in the middle of the river (C2), the river upstream (C3) and the river downstream (C4). Water Quality Indices and activity concentrations of 238U and 232Th were used as indicators of environmental and radiological impact of such water management system to the immediate water body. Results obtained showed that such water management system does not appear to impact the environment and may be the answer for some mitigation measures to reduce environmental problem related to effluent discharge from such plants. This study discuss current finding and provides cautionary statements to ensure conservation of the environment.
