Ramsar site East Kolkata Wetlands damaged; Measly compensation awarded

---

• The story: The cost of damage caused by garbage dumping and contamination of the 55-acre East Kolkata Wetlands, a Ramsar site, is Rs 1.46 crore, according to a joint report by state and central government agencies. Experts said this was ridiculous, and the actual cost is much higher and the duration of the study was very short.
• The study was carried out in October 2020 over three days, which the experts feel was too short for this kind of assessment. The report was ordered by the National Green Tribunal in context to a petition filed by a local environmentalist in May 2019.

1. Nearly 3,00,000 metric tonnes of solid waste has been dumped over Mollar Bheri (water body) in Salt Lake since the city came up in the 1970s in the northeastern fringes of Kolkata.
2. The study was done by West Bengal Pollution Control Board, National Environmental Engineering Research Institute (NEERI) and Central Pollution Control Board. The investigation found that the levels of several highly toxic heavy metals in the areas adjoining the dumping site “violate the acceptable limits for pond water and ground water”.
3. The petitioner Subhas Datta had alleged that the dumping of waste in Mollar Bheri by Bidhannagar Municipal Corporation and other urban local bodies has severely polluted the water bodies.

• Claims were correct: The report submitted to NGT vindicated Datta’s claims. It said that "It is observed that attributes like TDS (total dissolved solid), alkalinity, hardness, magnesium and TC (total colliform) … violates the acceptable limits. Volumes of lead, iron, manganese, cadmium, zinc and aluminum violate the acceptable limits for the pond water and that of aluminum, manganese, iron, cadmium violate the acceptable limits for the ground water."
• Toxic hazard: Most of the metals mentioned are highly toxic and contaminates aquatic plants and animals, particularly fishes. The toxins pose health hazards to a sizable population of Calcutta and Bidhannagar who consume these fishes, said a public health expert. The study was completed in haste during monsoon when the pollution level naturally get diluted, and the agencies should have consulted an environmental economist. The damage cost has not been taken into account for most toxic metals due to “lack of damage values available”, the authors wrote in the report.
• Mollar Bheri: The site is highly vulnerable to the environmental impacts from solid waste dumping, poses a potential threat to the surrounding water bodies and also contaminate the ground water table. The area is a legacy waste dumpsite of concern, where unsegregated solid waste was accumulated through December 2019. Mollar Bheri is part of a unique ecosystem where 234 ponds are inter-connected, the report said. A senior official from the environment department accepted that the report should be reviewed.
