Bandhwari landfill: leachate spills again, pollution office collects samples
Following repeated complaints from residents and environmentalists about the leachate spill in forest areas adjacent to the Bandhwari landfill, officials from the Haryana State Pollution Control Board visited the site and took samples on Friday.
A team from the wildlife department also visited the area for an inspection and found that the leachate mixed with the water in a drinking trough set up for animals in the forest area.
“Conditions are very bad there, with dirty leachate water pouring into the forest areas. There was leachate dumped in large quantities on the kuchha road (on the dump side) which leads to the villages inland, through the forest area. Samples have been collected by the Pollution Control Board, after which we will prepare a report and take action accordingly, ”a wildlife official said on condition of anonymity.
Vaishali Chandra, an environmentalist in the city, said: “Time and time again, leachate is released into the forests near the landfill, polluting the soil and their drinking water sources. We found two ponds formed behind the landfill filled with leachate and a third was a water trough for wildlife. If wildlife drinks water from there, their health will also be affected. ”
Kuldeep Singh, HSPCB Regional Manager, Gurugram North, said: “We collected samples from three sites which were sent for analysis. We will take action against the relevant authorities after the report is released within two weeks, combined with the findings of last month’s report.
Meanwhile, officials at Ecogreen Energy, the Gurugram Municipal Corporation’s concessionaire for Bandhwari landfill waste management, said they should check whether the water released is leachate or water. dirty.
Sanjeev Sharma, spokesperson for Ecogreen Energy, said: “To our knowledge, there is no release of leachate from the landfill; it will be necessary to see if it is dirty rainwater or leachate. The pollution control office can take samples at any time, we do not interfere with that.
Also in the second week of August, the HSPCB collected leachate samples from the Bandhwari landfill, which were analyzed to contain chemicals in excess of allowable limits as well as toxic substances.
According to the report, biochemical oxygen demand (BOD), chemical oxygen demand (COD), zinc, chloride and fluoride were all found to be significantly above allowable standards. The BOD level of samples taken from a pond inside the forest area was 540 mg / l, while the COD was 1680 mg / l, chloride was 420 mg / l, and fluoride was 1 mg / l.
Experts then said that things like fluoride, even in tiny amounts, can be harmful because they affect the bones of the human body. According to the standards of the Central Pollution Control Board, the BOD of a river or body of water must be less than 30 mg / l and the COD must be less than 250 mg / l.
