Land Clearing for tin ore mining on Bangka Island for hundreds of years produces mine ponds calledkolong. Water resources at the old age kolong have been utilized by the community as a source ofdomestic water, including the source of water by Regional Drinking Water Company (PDAM). Illegal tinore mining since 2000 until now by the community (unconventional mining) has caused pollution ofPDAM water resources by mining waste of tailings. Primary and secondary data collection has beendone on Kolong PDAM Tirta Bangka, PDAM Tirta Pinang and PDAM Sejiran Setason. Physical datacollection of water and sediments to obtain parameters of temperature, smell, soluble and suspendedsolids and turbidity. Chemical analysis of water and sediments including pH, heavy metal of Fe, Al, Pb,and Cu using AAS and XRF. Feasibility evaluation of the water using Permenkes RI Number907/Menkes/SK/VII/2002. Heavy metals were founded on all the water of kolong are Fe, Al, Cu andPb. Heavy metal in sediment are Fe, Cu, Pb, Sn and As. Kolong Merawang has a large distribution ofFe, Al, Cu and Pb in water and sediment. Al metal exceeds the threshold in Kolong Merawang andPedindang (1.01 mg/L and 0.35 mg/L). The Fe composition at all kolong sediment is very large innumber. The distribution of dissolved Pb metal in water exceeds the threshold at all kolong, especiallyon sediment of Kolong Merawang and Pedindang. Water resources at all kolong have met in physicalfeasibility but exclude their chemistry

Rare earth element REE is very potential future prospect mineral resources in Bangka Island, hence awell developed REE must have a high economic value in the future. As one of the biggest region thatproducing tin ore mining (cassiterite) for hundreds of years, REE potential not yet explored andexploited well until now days in Bangka Island, and was left abundant in ex-mining area. They carriedout from the tin ore mining and become mine waste or tailing and then through the stream flows to besuspension or bed load sediment. The aim of this study is to identify the present rare earth Ce and Ybased on shallow surface sediment samples and their spatial distribution from a number of mineponds called kolong. Primary data collection of shallow surface sediments has been collected onKolong Argotirto and Menjelang West Bangka District, Kolong PLN and Merawang in Bangka District,Kolong Rentensi Kacang Pedang and Pedindang in Pangkalpinang City. Geochemical sedimentsanalysis just for identification the presence of rare earth Ce and Y. Rare earth element of cerium(Ce) just presence in a few sample sediment, but for yittrium (Y) almost presence at all shallowsurface sediment 0,9 - 31,6 ppm. The spatial distribution of rare earth Ce and Y show heterogeneity inlaterally.
