| Summary: Based on water and stream sediment sampling during wet and dry seasons, this study aims at determining the seasonal variation of environmental pollution caused by the currently working Murgul copper deposit. Temperature, dissolved oxygen, As and Ba were found to have some differences between sampled water types. Except for Ba, which has differences between untreated and strained samples, all other parameters have similarity in strained and filtered water samples but differences in untreated samples. Comparison of sampled water types indicates that filtered samples are necessary where accuracy and element concentration are highly significant.All analyzed inorganic parameters were found to be highly polluted in untreated water samples collected when the mine is inactive. The resting of such samples and following straining gave rise to clean water for all inorganic parametres with respect to Class III criteria for water. Subsequent filtering achieved highly clean water with respect to first class water criteria concerning inorganic components. However, straining of water samples during active periods of the mine prevented all inorganic pollutants except for Cu based on the third class water criteria. After additional filtering, Cu, Zn and Mn pollution, and Cu pollution were found to be persistent with respect to third and first class water criteria, respectively. This indicates that prior to or following the straining and filtering processes, some chemical treatments are required to deposit or precipitate such pollutants to be able to obtain drinkable waters excluding organic pollutants. In the year of 2005, the Fe, S, As, Ba, Cd, Cu, Hg, Pb and Zn contents of the stream sediments were increasing from the mine dumps due to the effective working of mine and the sampling in the dry season but in the year of 2006, concentrations of these elements were decreasing owing to inefficient mining activities and wet sampling period. However, Si exhibited different behavior with decrement in the 2005 and increment in the 2006.Key Words: Murgul mine, Environmental pollution, Untreated water, Strained water, Filtered water, Water geochemistry, Stream sediments
