The NGT said in its order that the problem noted of management of waste and sewage, removal of encroachment and disposal of sodium sulphate waste/sludge generated from salt refining units still remain to be fully tackled .
The wetland was in the news in November last year after more than 20,000 birds died due to botulism, a neuromuscular illness caused by bacteria, to the concern of environmentalists and ornithologists.
Sambhar Lake’s polluted ecosystem is believed to be responsible for the country’s largest death toll in the last 30-40 years of waterfowls, who are believed to have fed on maggot-infested carcasses leading to deadly neuromuscular disease, botulism.
The NGT bench ordered that the National Wetland Authority, State Wetland Authority, Rajasthan State Pollution Control Board and Jaipur district magistrate to file a joint factual and action taken report before the next date of hearing on January 22, 2020.
