The aim of the current investigation is to encounter the causative agent for the pink coloration of water along with the nature of water quality in Chennai, Tamil Nadu. The pink water sample was collected near Perungudi garbage dump yard in Chennai. Water quality parameters for the sample including Appearance, Odour, Turbidity, Temperature, pH, Salinity, Dissolved Oxygen, TDS, TSS, Total solids, Electrical Conductivity, BOD, COD, Total Hardness, Alkalinity, Total ammonia, Nitrite-nitrogen, Nitrate-nitrogen, Calcium-hardness, Magnesium-hardness, Inorganic Phosphate, Oxidation-reduction potential were analysed. While analysing the algal composition, 22 algal species were identified from the sample. Cyanobacteria (blue-green algae) dominated the pink water. The commonly occurring genus identified in this study were Merismopedia, Oscillatoria, Chroococcus. Various pigments such as Chlorophyll a, Chlorophyll b, Carotenoid, total Chlorophyll, Phycocyanin and Phycoerythrin were also estimated. Abundant of Phycoerythrin (pink colour pigment) in sample water clearly depicts that the Cyanobacterial stood as the major contributor for pink colouration of water in that area
