|a AMD stands for Acid Mine Drainage. AMD results from the mining activitiesinvolved during mineral exploration. When minerals interact with each other in the presenceof atmospheric oxygen and water AMD is the end product. AMD also accumulates from theweathering of sulphide minerals through the process of oxidation and hydrolysis. This casestudy was being carried out for the investigation of the occurrence of Acid Mine Drainage(AMD) and contamination of the heavy metals in the active and abandoned mining sites inBentong Pahang. This case study deals with the traces of heavy metal toxins found in thewater bodies causing the discoloration of the water catchment, downstream of the Old Repasdam. This discoloration of water proved the occurrence of AMD which is a very bad pollutant.To get a better understanding of the situation, site reconnaissance and survey were carried outto examine those areas closely that have been affected by AMD. Two different samplingpoints were recognised which had traces of AMD contamination. Water testing and samplingwere to be carried on these particular sampling points. Four in-situ parameters and five heavymetals were selected for sampling. These parameters included PH of water, dissolved oxygencontent, Total dissolved solids and Ammoniacal Nitrogen while the heavy metals includedZinc, Lead, Tin, Mercury and Arsenic. A total of four samples were collected on two differentsampling points and on two different sampling days. Sampling was carried out, theseparameters were measured and surface water with sediments were also collected and analysedfor heavy metals. Based on the investigations done during this project, these sampling pointshad acidic PH values which indicate the occurrence of the Acid Mine Drainage, which hadbeen a major find in this case study. During the Heavy Metal analysis the concentration of Pb,Sn, Hg, As & Zn was observed to exceed the allowable standard limits for treated water bythe Malaysian Ministry of Health. I concluded this with the believe that there was an urgentneed for appropriate treatment of this site to prevent further environmental deterioration
