This research has included quarterly and periodically physical and chemical analysis of treatment wastewater in the rural areas of Latakia city during year 2011 by testing three treatment plants similar in the mechanism of action and distributed in three villages (Happit, Al-Harah, Marg Moairban). This study has included the measurement of temperature T, pH, and determination of sodium, potassium, calcium concentrations, and sodium adsorbed rate (SAR). This study was based on the potentiometrictechnic using Ion Selective Electrodes (ISEs). SAR measurements have shown that there are clear differences between autumn and other seasons, and between treatment plants. The highest values was in the Happit treatment plant in all seasons and the highest value was (88.25 mg/L) in the autumn which is much larger than the allowable limit. The highest concentrations of sodium ion were in the autumn in all treatment plants (1002.67-7130.33) mg/L, which is off limits. As for the potassium ion concentration was highest (72.46 mg/L) in Happit treatment plant in the autumn. While calcium ion concentrations in Al-Harah treatment plant was exceeded (670.33-800.00) mg/L the allowable limit in all seasons except the summer. The statistical study has demonstrated and showed strongand sometimes weak correlation coefficient R2 so that gives clear indications about the sources of pollution.
