ABSTRACT

 

The present study deals with the study of water quality of Pitkati wetland, Assam, India for physic chemical parameters i.e, Dissolved oxygen (DO), Biological oxygen demand (BOD), Chemical oxygen demand (COD), Total hardness (TH), Total dissolved solids (TDS), Water temperature (WT) in the year 2014 for pre monsoon season . Low value of dissolved oxygen is observed during pre monsoon season and high values of COD, TDS, TH are observed..The correlation coefficient showed positive and negative relationships among the water quality parameters. Linear Regression equations of the parametrs are also evaluated. The study revealed that the wetland water is moderately polluted.
