Rivers in Kerala detect increase in cyanobacteria after floods
Palakkad: A rising level of contamination is reported in the water bodies across the state after floods, reports the Centre for Water Resources Development and Management. The degree of contamination in the southern rivers of the state has crossed more than 75 percent.
The contamination is mainly caused due to septic tank waste released into the water bodies. Due to this, the color of water turned green and it stinks badly. Cyanobacteria produces toxins like cyanotoxins. The water contaminated by cyanobacteria causes neuralgia and kills the fish in the water bodies.
Before floods, 29 out of 44 rivers in the state were found contaminated. The presence of cyanobacteria increased in Chalakkudi river, Meenachilar and Achankovil after floods. The centre for water resources development suggests that the State Pollution Control Board should regulate the waste water disposition into water resources.
The centre for water resource development has also warned that there could be more pollution issues as the rivers in the state have undergone changes during the floods. More details can be revealed based only on this year's north east monsoon. Inspection of water in the wells in flood affected areas are undergoing. When it is completed, studies will be conducted based on more rivers.
