Paper Title
Groundwater Quality Assessment FOR Agricultural and Industrial Applications in the South Part of Tehran, Iran

This paper aims to investigate the groundwater quality for agricultural and industrial purposes in southern Tehran, Iran. In this regard, sampling was performed in 20 wells. Results indicated that about 25% groundwater samples (wells) had electrical conductivity(EC) higher than 3000 and therefore they are harmful for agricultural purposes. For the majority of samples, the sodium adsorption ration (SAR) was within the acceptable range and thus suitable for irrigation. Residual sodium carbonate (RSC) of all the water samples was negative that indicates the suitability of all wells for irrigation application. Also, findings suggested that about 80% of wells were not suitable to use for industrial purposes based on calculated saturation index of calcium carbonate.
