Evaluation of Water Quality of Padavagodu Tank, Sagar Taluk, Karnataka, India

摘要

The stagnant waters such as ponds or tanks and lakes are usually called lentic waters. The pollutants concentrate themselves differently in these zones based on prevailing physical and chemical conditions. These zones are usually inhabited by specialized organisms adopted to environment. The large number of chemical compounds are brought to the waters by discharge of sewage, industrial wastewater and agriculture runoff, and several of them are poisonous to life in varied concentrations and may affect the fish culture. The present study deals with physico-chemical characteristics like temperature, pH, EC, TDS, Cl, TH, total alkalinity, acidity, turbidity, NO_3, PO_4, dissolved oxygen, biochemical oxygen demand, free CO_2, calcium, magnesium, sulphates, dissolved organic matters in the Padavagodu tank water studied from December 2009 to November 2010. Data were collected from one sampling station to evaluate the water quality for human consumption and irrigation. The study revealed that physico-chemical data were within WHO and BIS standards. Hence, it was concluded that water is suitable for drinking, irrigation and fisheries.
