NEW DELHI: As authorities hanker for a space to be utilized as landfill site, the existing Bhalswa-Jehangirpuri dumping ground of waste in the Capital has overflowed its capacity, posing a threat to groundwater resources.
The Comptroller Auditor of General (CAG), in its latest report, has said the dumping ground in north Delhi posed a major threat to the groundwater resources in the area.
According to the report titled 'Management of Waste in India' , the Total Solid Waste (TDS) as well as hardness content of groundwater near the site was 800 and 633 per cent respectively, which is more than the permissible limit.
Analysis of leachate from Bhalaswa landfill site revealed that TDS was higher by 2,000 per cent and the hardness content was 533 per cent in excess of the limit, the report says.
"The presence of high chlorides 4,100 mg per litres and 10,995 mg/litres against the desirable limit of 250 mg per litres also indicates the critical condition of the landfill site located in north Delhi ," it adds.
Similarly, TDS at Okhala landfill site was also 244 per cent more than the desirable limit.
"This shows that the groundwater of landfill sites has been critically contaminated with leachate generated from the site. Ambient air quality monitoring work for the year 2005 has been conducted which indicates critical levels of air pollution in the area," the study based on the analysis conducted last year said.
