Description 859-869
Present study consists
the microbial and nutrient quality of water along three coasts of Odisha over a
period of three years (2008-2010) on seasonal basis (pre- monsoon, summer and
post-monsoon). Water samples were examined for total viable count (TVC) and
pollution indicator bacteria. Physico-chemical parameters (pH, salinity,
dissolved oxygen and biochemical oxygen demand) and nutrient concentration
(nitrate, nitrite, ammonium, phosphate, total nitrogen and total phosphorous)
were examined to assess the physical condition of water. Highest average value
of bacterial population was observed during summer, which may be due to the
higher concentration of nutrients and the optimum temperature for bacterial
growth. Lowest was recorded during pre-monsoon (Puri and Mahanadi)
and post-monsoon (Paradip) season.

Significant positive
correlation was observed between pollution indicator bacteria and pathogenic
bacteria which imply their co-presence, and also with the nutrient
concentration which suggest that elevated nutrient load favors the bacterial
growth.
