H. A. Sayeswara, H. S. Ravikumar Patil and Mahesh Anand Goudar

Purle pond of Shivamogga is one of the important sources of water supply to agricultural areas receives domestic waste water almost throughout the year and exhibits abundance of phytoplankton population. An year long study was conducted to measure various physico-chemical parameters like temperature, turbidity, conductivity, hydrogen ion concentration, free carbon dioxide, dissolved oxygen, BOD, alkalinity, hardness, presence of various radicals etc., The turbidity of pond water was found to be highest during June-July and lowest in the month of November. BOD was highest in the month of July while lowest in December. The study revealed that there is greater degree of pollution in the studied pond and hence, preventive measures are required to avoid further deterioration of the pond water quality. The estimated water quality parameters were compared with the WHO and IS standards.
