Survey of Some Water Quality Parameters in Sistan Drinking Water Sources (Chahnimeh Reservoir Number 1) and Compares Them with Existing Standards
Background And Objective
The Chahnimeh reservoirs in Sistan currently provide main source of drinking water for Zabul and Zahedan Cities. Therefore the survey of quality factors in this region appears to be essential. The aims of this study are survey of water quality factors (sulfate, nitrate, magnesium, ammonia, alkalinity, calcium, chlorine and hardness) and comparison among sampling stations and available standards.
Samples for laboratory studies were collected from 6 stations including 19 points in August 2010 from the surface of Chahnimeh. During sampling the EC and pH were measured. Then each factor was obtained with photometer 8000 Palintest. The statistical analysis was promoted with SPSS software and Excel was used for graphs.
Findings: According to the results, Sulfate obtained between 106-124 mg/l, Magnesium concentration based on CaCo3 measured between 416-600 mg/l, Ammonia concentration between 0.02-0.10 mg/l, Nitrate concentration between 0.52-0.93 mg/l, Alkalinity between 125-215 mg/l, Hardness between 182.66-205.33 mg/l Calcium Carbonate, EC between 559.33-604 Calcium, Chloride and Hardness µm/cm and pH between 8.45-8.79 was variable. Based on statistical analysis, any factors was not show significant different among stations.
Accordingly, these factors have the same distribution among the stations and they are not affected by point sources. Each factors was compared with available standards for drinking water. These comparison were suggest the factors including sulfate, nitrate, ammonia, alkalinity, calcium, chlorine, hardness, pH and EC have been lower than the standards set for drinking water While, The concentration of magnesium was higher than the levels them. According to the results, Chahnimeh Reservoir has desirable quality.
