Assessment of the HablehRood river water quality for drinking and irrigation purposes in Garmsar, Iran

Rivers are one of the most valuable sources of water for drinking, agricultural, and industrial use. In the presented study, water samples collected from different rivers of HablehRood from October Within 23, 2009, to the end of September 2014, were analyzed to assess qualitative analysis and suitability for domestic and irrigation usage. The electrical conductivity (EC) of the river water was within the range of 750–5000 μmoh/cm, sodium adsorption ratio (SAR) Classification indicated that all samples were excellent and good range, sodium percentage (Na %) 20–80%, residual sodium carbonate (RSC) < 1.25 and Wilcox diagram were class 3–4. However, the cation chemistry indicated that out of 73 water samples, average samples showed a dominant sequence of > \({\mathrm{Na}}^{+}{\mathrm{Mg}}^{2+}\)> \({\mathrm{Ca}}^{2+}\) and \({\mathrm{Cl}}^{-}\)> \({\mathrm{SO}}_{4}^{2-}\)>\({\mathrm{HCO}}^{-}_{3}\). The water quality showed high EC and total dissolved solids (TDS) in all water samples, which reduce quality for livestock and drinking because of high TDS levels. Still, according to the Wilcox diagram is suitable for agriculture.
