NIDHI SINHA AND AMAR NATH JHA

Abstract

Studies on the analysis of physico-chemical factors of three ponds at B.R.A. Bihar University campus Muzaffarpur, Bihar, India was undertaken during of January to December 2010. The study revealed that the water temperature ranged from 13.18-28.5°C, pH varied from 7.3-8.9, and water transparency 37.4-72.1cm. The dissolved oxygen varied between 3.8-7 ppm, free carbon dioxide ranged from 4.6-12ppm, total alkalinity varied from 62.1-132.9 ppm, total hardness varied in between 61.8-135.0ppm. In the present study phosphate content varied between 0.42-1.78ppm, Nitrate content was between 0.92-1.70ppm. Both the BOD and COD varied in between 20.8-49.3 mg/L and in between 58.8-122.0mg/L respectively.
