Abstract: The study provides a baseline for the assessment of the inorganic pollution specially, metal contamination in the water Armağanköy dam, Ergene River basin. A survey of inorganic chemicals was performed in water samples collected in Armağanköy dam reservoirs during 2015. Water samples from six sampling sites were collected and analyzed for 10 different water quality parameters. Using these data, a regional irrigation water quality was assessed using one technique: United States Department of Agriculture Method (USDA). This method revealed that the dam water salinity, as represented by electrical conductivity, ECw, ranges from low salinity (C1: ECw < 250 micromhos cm–1) to medium salinity (C2: ECw < 750 micromhos cm–1). The sodium adsorption ratio (SAR) is low (S1) sodicity. Therefore, the water of the dam is dominantly of the C2–S1 class and C1–S1 classes at the sampling site of 1, 2, 3, 4, 6 and 5, respectively. Inorganic analyses were performed according to USEPA method. The cation concentrations are gradually decreases from the February towards the April. Cu2+ and Mo2+ displayed higher values in the dry season, while higher values for Fe2+ and Mn2+ in the wet season. The concentrations of Fe2+, Mn2+ and Mo2+ are generally higher than the other sampling sites at the sampling sites 1 and 6. Correlation analyses showed that metal content of Armağanköy dam water was affected by pH, ECw and TSS. The heavy metal concentrations in the water samples from the dam reservoirs followed the order: Mn2+ > Fe2+ > Mo2+ > Cu2+.
