Impact of seasonal variation on water quality of Hindon River: physicochemical and biological analysis

Abstract Water is the basic necessity for a living being and detritions in quality of water led to many harmful impacts. It important regulate maintain balance all variation lives. In present study, samples were collected during pre-monsoon post-monsoon periods February 2015–January 2017 from Mohan Nagar barrage, Ghaziabad (Uttar Pradesh, India). The assessment seasonal its impact on Hindon River was evaluated by physicochemical biological analysis. Samples analyzed twelve parameters such as Dissolved Oxygen (DO), Biological Demand (BOD), Chemical (COD), Total Hardness (TH), Nitrate Nitrogen, Phosphates, Sulphates, Heavy metals (Cadmium (Cd), Lead (Pb) Iron (Fe), Zinc (Zn) Coliform count (TCC), Fecal (FCC) Standard Plate (SPC). Besides this, Metal Pollution Index Integrated also calculated found above permissible limits (RMPI > 1 IMPI 2). trend heavy metal load observed be Fe Zn Pb Cd. Lower recorded values DO higher levels EC, TDS, BOD, COD, TH, Sulphates indicate high pollution water. TCC (MPN/100 ml) 7.4 × 10 4 season 5.8 season, FCC 4.5 3.6 whereas SPC (CFU/ml) 75 62 post-monsoon. Analysis performed per Methods (APHA, 1998). Correlation coefficient matrix has been obtained validate interrelationship between different parameters. results our study show regular monitoring integrity aquatic flora, fauna, human health.
