Hydrobiological study on Summer, Rainy and Winter season of river Deorania at Bareilly
The waters of the Deorania River have been found to be a good model for studying the effects of sewer pollution. Therefore, the effect on hydrobiology was tested during different extreme points of the winter, summer and rainy season. Samples were collected from three different sites. Site A (unpolluted near Thana Bhojipura), site B (near the city Shamshan Bhoomi, about 50 meters away from the point where major drains of city joint the river) and site C (it is about 3 Km. away from the point where major drains join the river). The water of the river was analysed for hydrobiological parameters; temperature, colour, TSS, transparency, pH, DO, free CO2, COD, BOD, TDS, and salinity. The results indicate that all parameters at site B and C are beyond the permissible limit and unsuitable for human consumption and unfit for irrigation, dairy form, industrial use. Industrial effluent and domestic sewage contribute a source of pollution in river water. Till date there is no hydrobiological study performed on this river with respect to all three seasons therefore the study will be very beneficial for the whole scientific community.
