The holy river Saryu has been facing serious pollution problem as the input of sewage, industrial, agricultural and domestic wastes are contaminating the river resources. Therefore, it was envisaged to analyze the hydrological characteristics and level of metals of holy river at four major sites (A-Kakarahi Bazar, B-Retia, C-Jamthara Ghat and D-Sahebganj Nalla) of Ayodhya-Faizabad. A laboratory study was conducted to understand the hydrological characteristics (pH, Temperature, EC, Free CO2, TDS, DO, BOD, COD, Total Hardness, Nitrate-N, Phosphate-P and Sulphate as SO4) and the level of metals (Cu, Cd, Zn, Fe, Pb, Mn and Cr) of city sewage water which was released into holy Saryu river through four major discharging sites. The results revealed that out of the four sites, site-D was more polluted, as all these parameters were found to be beyond the permissible limit. Since the municipal sewage treatment plants are not available, therefore it is suggested that before releasing the sewage, treatment plants should be properly made to maintain ecological balance of the holy river for the growth and survival of the organisms including human health.
Water is one of the most important natural resources. Unfortunately, industrialization, urbanization and population explosion have led to deterioration in the standard of water quality. A major portion of domestic sewage water flows into open drainage in which various plants and weeds are present. The discharge of waste water into the open drainage through several drains enhances the pollution level.
