Toxic foam caused by sewage flow into Marina Beach
On Sunday, 8th February, snow-like foam appeared along Marina Beach from Napier Bridge to Kannagi Statue. People could be seen playing with the foam and going into the water. Researchers have pointed out that the foam is actually caused by toxic algal blooms when there is free flow of sewage into water bodies.
According to a report carried out by National Coastal Research Center, toxic algal blooms have appeared eight times in India over the last eight years or so. In the case of Marina, researchers trace the sewage from the Cooum River, mixing with the saline coastal waters, resulting in these algal blooms. The phenomenon usually occurs due to high amounts of phosphate in the water, especially during or after monsoons, when the phosphate content in the sewage is high.
The phenomenon affects fisher communities in particular, as it poses a great threat to their livlihood. According to S Palayam from Coastal Resource Center, fishing hamlets from Ennore to Besant Nagar have depended on the two rivers for their livelihood, but due to indiscriminate inflow of sewage in the past few years and inadequate drainage systems implemented for fishing hamlets, both rovers have become extremely toxic and not viable for fishing.
