The quality of water may be assessed according to its physico-chemical and biological characteristics because of increasing industrialization, urbanization and anthropogenic activities from all fresh water bodies. At present industrial effluents sewage water, domestic wastes and agricultural wastes are being discharged into the river and oceans that causing degradation of water quality. An investigation was undertaken to assess the nutrient analysis, in Adirampattinam Mangrove region for four seasons (pre-monsoon, monsoon, post-monsoon and summer) during the year July 2010 - June 2011. For the present study two sampling stations were fixed viz. Mangrove water (Station I) and Adirampattinam coastal waters (Station II). Nutrients of water in the study area (Total Nitrogen, Total organic carbon, Total phosphate, nitrate, nitrite, free ammonia, calcium, magnesium, Iron and sulphate OC, PO4, SiO2, NO2, NO3, Calcium, Magnesium, Iron and Sulphate) also exhibited high values during the monsoon season and low values were recorded during the summer seasons. Except free NH3 which also exhibited high values during pre-monsoon season and low values during post-monsoon seasons.
