Abstract
This paper is envisioned to be a study concerning with surface water quality in Janivara water body, Hassan District, Karnataka (India) based on physicochemical and nutrient status and water quality according to water quality guidelines. Water bodies are sometimes subjected to sewage and wastewater discharges originating from different sources. Some of the chemical and nutrients such as nitrogen, phosphorus and carbon in certain concentrations might twist and disorder the characteristics of lentic aquatic ecosystems. This study, purposing to determine water quality characteristics of Janivara water body, located in Channarayapatanme taluka, Hassan district, began in April 2013 and was carried out for 12 months by taking bimonthly intervals water samples from four different locations. Water quality parameters of temperature, pH, dissolved oxygen, chemical oxygen demand (COD), total alkalinity and hardness, ammonia, nitrite, nitrate, phosphate, sulphate, chloride, potassium and sodium analyses were done. Changes in water quality parameters of Janivara water body indicates that not yet Janivar water body reached the eutrophic stage and degradation stage. The study also reveals that all physico-chemical water parameters of the Janivara water body are well within the permissible limit of ICMR, BIS and WHO
