Background/Objectives: Near shore or coastal water bodies are important sources of marine environment. Water is inevitable properties for the living being. Water quality assessment is important in understanding biological phenomena of coastal zone.

Methods/Statistical analysis: Water and sediment samples were collected from Nagapattinam coastal water at monthly interval from July’ 2016 – June' 2017 to analyze various physico-chemical parameters in water and sediments.

Findings: The water temperature values ranged from 22°C to 32&#176C. Salinity ranged from 28ppt to 35ppt. The pH values ranged from 7.6 – 8.2. DO values varied from 4.1 ml L-1 to 5.2ml L-1. The water nutrient concentrations observed as: NO2:0.96 – 4.509 μg L-1, NO3:0.603 μg L-1 to 2.498 μg L-1, TN: 6.004 – 14.52 μg L-1, IP: 0.398 – 1.0198 μg L-1 and TP: 0.516 – 2.127 μg L-1 were recorded respectively. The nutrient concentration observed in sediment ranged from TN, 5.408 μg L-1 – 13.918 μg L-1, TP, 7.54 μg L-1 – 16.872 μg L-1 TOC, 6.68 μg L-1 – 13.882 μg L-1 respectively.

Application/Improvements: Physico-chemical variations of water are accountable for the aquatic organisms. Which is interactive with physical, chemical and biological processes of the coastal ecosystem for sustain life. The nutrients provide the potential fertility for water masses and it is necessary to collect the data for their distribution. Hence, the present work has been carried out the physico-chemical characteristics of Nagapattinam coastal waters in Tamil Nadu, India.
