The pollution status of freshwater ponds in Chavara, an industrial area in Kollam district, south west coast of India was studied seasonally for a period of one year from January 2014 to December 2014. The parameters determined for the study were pH, conductivity, total dissolved solids, alkalinity, total hardness, Chloride, Dissolved oxygen (DO), Biological oxygen demand (BOD), Chemical oxygen demand (COD), sulphate and nitrate concentrations. The study revealed that maximum conductivity, TDS, Chloride, Total Hardness, BOD, sulphate and COD were recorded during summer and minimum during the monsoon season. pH and total alkalinity was found to be high in post monsoon period and low on summer. Maximum DO was recorded during monsoon and minimum on summer. Highest value of Nitrate was observed during pre monsoon and lowest value on summer. The study indicated that the waste water from the industrial area is deteriorating the water quality of nearby water bodies.
