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.

Plans to revive much awaited Sriperumbudur Railway line
The Railways Department is planning on reviving the Sriperumbudur to Guduvanchery new line nine years after including plans for the same in the 2013-14 budget.

However, the project was frozen by railways, before construction could begin, as they wanted to invest in priority projects.
The line would help commute freight and passengers working in the industrial belts in the western and southern parts of the city. These areas include: Ambattur, Sriperumbudur, and Orgadam. The project costs around 839 Crores and is said to develop in phases.

Palar Bridge diversion leaves commuters stranded for hours
Palar Bridge near Chengalpet is currently undergoing repair work, leading to diversions in traffic on the Chennai-Tindivanam Highway to make way for the work. On Monday and Tuesday night, vehicles coming in from Madurai, Trichy, Coimbatore and Salem, on their way to Chennai, were stranded on the national highway for 5 hours. On Tuesday evening, many vehicles in order to avoid delay, took the Thirukazhukundram- Kelambakkam route to get into the city, however, this resulted in excess traffic in OMR.
The work is taking place over the two bridges which span across Palar River. It was actually supposed to be completed back in 2020 by National Highways Authority of India (NHAI), but was delayed due to the pandemic and heavy rains. The work involves replacing expansion joints and damaged hand rails and is said to continue for the next 60 days.
