Pamba River is the third largest river in the South Indian State of Kerala. Due to the lack of conservation and protection by human beings, the Pampa is under the threat of Pollution. Physical and chemical parameters degrade water quality causing health issues in living organisms. The present study examines the variation in these parameters in the Pamba River at Ranni. Water samples were collected from five different sources at Mamukku, Ranni and tested at CEPCI, Kollam. In the laboratory, the physio-chemical parameters like pH, BOD, TDS and heavy metals like copper, chromium, Cadmium, lead and mercury (Cu, Cr, Cd, Pb, Hg) content in water were analyzed. The study showed that the water quality at Ranni is fit for domestic use in terms of heavy metals. However, BOD levels were elevated due to the pressure of organic waste that could have been entered due to the presence of chemical and sewage wastes in water bodies at Ranni. Among the five heavy metals, Copper and Chromium were below the standard limit and the other three heavy metals Lead, Cadmium and Mercury were below the detected level. The regular water treatment methods adopted in the area due to recent floods may be the result of water quality in Ranni with respect to heavy metals. The physical parameters like pH of water sources in Ranni are normal except well water which is slightly acidic due to chemical runoff and wastewater discharge. The TDS levels are normal in all five sources but BOD levels are elevated due to the presence of organic wastes entered from chemical and sewage disposal in water bodies. Follow-ups are required to monitor the overall quality of the river.
