Chah-Nimeh reservoirs are important drinking water resources in Sistan and Baluchistan province in Iran. Their water is widely used to supply drinking water of Zabol and Zahedan cities and for agricultural and recreational purposes in this province. An environmental monitoring program is designed and developed due to the importance of investigating the qualitative water condition of Reservoir No. 1, which only has the main entrance and exit water from the Sistan River. To this end, 23 physical, chemical, and biological parameters are monthly studied in 8 sampling stations. Then multivariate statistical methods, ANOVA, cluster analysis, factor analysis, component analysis were used to determine index parameters, main and secondary stations, and sampling frequency in order to determine and design an appropriate water quality monitoring system. Finally, the findings of our experiments showed that the, Stations 4, 5, and 6 are main sampling stations and temperature, turbidity, dissolved oxygen(DO), chemical oxygen demand(COD), magnesium, sodium, calcium, phosphate, chloride, nitrite, sodium absorption rate (SAR), and pH are indicator parameters between 23 parameters. |
