Industrialization, urbanisation and agricultural development cause pollution in water bodies due to the discharge of wastewater directly or indirectly. The present study aims to assess the water quality of water bodies in and around A D Nagar, Badharghat, Dukli and Budhjungnagar Industrial Estates, West Tripura during pre-monsoon and post-monsoon in the year 2016 to 2018. Biological parameters namely DO, BOD, Total Coliform, Faecal Coliform and COD, Physico-chemical parameters namely pH, EC, TDS, Bicarbonates, Chlorides, Sulphates, Total Hardness, Calcium, Magnesium etc. and heavy metals were analysed using standard methods as prescribed by APHA. The analysed parameters were compared with the standards prescribed by BIS. The BOD values for all the water bodies were beyond the prescribed standard limit except the pond located at the southern side of Jutemill, Hapania (S-3) during pre-monsoon season. The Total Coliform values for water bodies located at the eastern and northern side of Badharghat Industrial Estate were beyond the prescribed standard limit. The seasonal variations of water quality have also been observed. Water Quality Index values reflected that the 75% of surface water samples were of poor quality and 25% were of good quality in both the season. Correlation study revealed that positive and significant correlations between the pairs of selected parameters in surface water samples were observed. This study reveals that the surface water of these water bodies needs proper treatment before consumption and it also needs to be protected from the domestic as well as industrial contamination.
