Abstract
Analysis of water samples drawn each month of the experimental year 2015-16 from Ramganga river for various physico-chemical quality parameters were done by employing standard APHA guidelines. The range for demand parameters viz Dissolved Oxygen, Biochemical Oxygen Demand and Chemical Oxygen Demand were observed 5.8-7.8, 1.2-2.6 and 72-128 mg/l respectively. The values of calcium in analyzed samples were well within the BIS standard but that of magnesium breached the standard. The free CO 2 was found to be absent in pre-monsoon period for six consecutive months whereas in case of carbonates the absent status was found in post monsoon for six sequential months. The total hardness values ranged between 224-446mg/l with highest value in September. Strong positive and significant correlation was observed between chloride and DO as well as between BOD and carbonates present in the samples, whereas negative correlation was observed for free CO 2 with pH, DO, bicarbonate and chloride.
