It is believed that groundwater is naturally protected from the pollutants. However, it gets contaminated from percolation of dissolved salts and heavy metals associated with wastewater from the surface of the earth. The main purpose of the study was to assess the concentration of dissolved salts and heavy metals present in the groundwater. The amount of sodium and potassium was determined by flame photometer. Titration method is applied for the examination of other dissolved salts. Heavy metals were investigated by Atomic Absorbance Spectrophotometer. It was found from the analyses that the concentration of chlorides in the groundwater samples was five times higher than European Union guidelines values. The values of sodium, potassium, magnesium, calcium and sulfates were 5, 3, 2, 2 and 1 times higher than the standards respectively. The amount of heavy metals was low except cadmium, lead and nickel. Their results were 3.5, 2.5, and 1.1 times higher than World Health Organization Standards respectively. It was concluded that the groundwater quality was deteriorated by the percolation of dissolved salts and by two heavy metals namely cadmium and lead.
