		+	New Delhi : Showing signs of sustainability, the city recharged more groundwater than it extracted in FY 2021-22, according to a report by Central Ground Water Board (CGWB).
		+	This is the first time since at least 2009-2010 that the city’s recharge is more than its extraction.  The report, titled ‘Dynamic Ground Water Resources Assessment of India – 2022’, said compared to 2020-21, the total annual groundwater recharge increased from 0. 32 bcm (billion cubic metres) to 0. 41 bcm. The annual extraction, including artificial and due to natural discharge, went up too, from 0. 322 bcm to 0. 4 bcm. Therefore, overall, extraction decreased from 101. 4% to 98. 1%.
		+
		+	The study highlighted some concerns too. For instance, the city’s extraction is the fifth highest in the country after Punjab (165%), Daman & Diu (157%), Rajasthan (151%) and Haryana (134%), and much higher than the national average, which is over 60%.
		+
		+	Afew areas are now out of overexploited zones, the report said. Out of 34 units, or tehsils, 15 have been categorised as ‘overexploited’, seven as ‘critical’, eight as ‘semi-critical’ and four as ‘safe’.  In terms of area, out of 1,487. 6 sq km that is ‘rechargeworthy’, 709. 8 sq km (47. 7%) is‘overexploited’, 179. 3 sq km (12%) ‘critical’, 396. 7 sq km (26. 6%) ‘semi-critical’ and only 201. 5 sq km (13. 5%) ‘safe’.
		+
		+	An area is overexploited when the stage of groundwater extraction is more than recharge or over 100% while 90-100% extraction falls under critical, 70100% under semi-critical and less than 70% under safe.
		+
		+	Delhi, the report stated, is critical in terms of groundwater extraction. About 89% of the city is occupied by alluvium and groundwater is being tapped mostly through tubewells.
		+	“The increase in groundwater extraction can be attributed to refinement in the database. About 12,000 private tubewells, which have been registered with DJB, have been incorporated in the estimation. Refinement of data on piped water supply and increased piped water supply by DJBin many areas led to an increase in recharge due to return seepages,” the report stated.
		+
		+	Experts said the news of groundwater extraction being less than recharge is welcome, but also pointed out that the report was “silent” on many aspects.
		+
		+	“In Delhi, out of 34 assessment units, over 44% are overexploited, which is higher than the national average. In those tehsils, overexploitation will lead to a sharp decline of water levels and depletion of groundwater levels,” said Dr SK Sarkar, distinguished fellow, water division, TERI.  He pointed out that the report stated that due to additional data, both total extraction and recharge have gone up.
		+
		+	“The artificial recharge and rainwater harvesting augments groundwater. If piped water supply is high, the dependence on groundwater is less. In Delhi, recharge has gone up, but how? The report is silent on this aspect,” he said, adding that the report also does not mention the quality of groundwater.

		+
		+	Large parts of the capital have seen a drop in the groundwater table by four metres or more, a decadal analysis carried out by Central Ground Water Board (CGWB) between 2005 and 2014 has shown. A more recent analysis says Delhi is losing groundwater at 0.2 metres on average every year.
		+
		+	While Delhi has the potential to utilise 457 million cubic metres of surface runoff rainwater, waterlogging on streets during the season’s first downpour showed the capital was failing to capture a large chunk of it.
		+
		+	According to data, around 87% of Delhi’s monsoon occurs between June and September (533.1mm out of 611.mm of rainfall), making it a key period to recharge groundwater aquifers. CGWB’s decadal data shows that while the groundwater table has fallen by 2-4 metres in almost every location, parts of Delhi along the Yamuna floodplain, central Delhi, southwest near Najafgarh and a part of northwest have shown an increase, indicating more recharge over extraction.
		+
		+	For central Delhi, rainwater harvesting has played a key role with a number of government buildings utilising such units to increase groundwater recharge. According to the National Project for Aquifer Management (NAQUIM) report released by CGWB recently, areas such as JNU and Sanjay Van recorded good groundwater recharge, but just next to it Hauz Khas and Greater Kailash showed considerable extraction, more than what was being replenished through rainwater harvesting.
		+	The NAQUIM report recommended groundwater extraction only along the Yamuna floodplain or in parts of north and northwest Delhi, while also highlighting poor groundwater quality in southwest district, largely along Najafgarh and Dwarka.
		+
		+	The latest CGWB data from May 2019 showed that out of 73 wells analysed across Delhi, six had a depth of over 40 metres below ground level (mbgl) and 13 wells were between 20 and 40 mbgl. The deepest point was 62.6 mbgl in South district, while the shallowest point was in South West district at 1.1 mbgl. North district had the best water levels, all ranging between 2 and 10 mbgl.
		+
		+	Diwan Singh, a water activist, who has worked on the revival of several waterbodies in Dwarka, said simple utilisation of stormwater drains could help capture millions of litres of rainwater, which could be diverted to recharge pits or waterbodies. “Over time, these waterbodies recharge the groundwater table naturally. Instead of letting rainwater go to waste, there are ways to utilise it better,” he added.

		+	The groundwater near the city’s three landfill sites at Bhalswa, Ghazipur and Okhla is highly contaminated with the level of total dissolved solid (TDS), chlorine and hardness being higher than the desired drinking water limit. Calcium and sulfate were also found to be higher than the desired limit. This was revealed in a report by Delhi Pollution Control Committee (DPCC), which had collected samples from 4-5 locations near each landfill site in July last year.
		+
		+	Experts said unsegregated waste at the landfill sites leaching into the soil was contaminating the groundwater. Priti Banthia Mahesh, chief programme coordinator of the NGO Toxics Link, said, “All types of waste are dumped at landfill sites. The unsegregated waste, including toxic materials, releases chemicals and it leaches into the soil and contaminates the groundwater.”
		+
		+	“The Solid Waste Management Rules state that all sources of waste should be segregated at source. However, segregation at the household level is not happening and there is little option of separating it at a later stage. The presence of toxic materials at landfill sites will have an impact in and around the area,” added Mahesh.
		+
		+	Shashank Shekhar, professor, department of geology, Delhi University, said, “These landfill sites are very old dumping grounds and were not scientifically designed. In due course, the leachate enters the groundwater and starts polluting it, which is occurring at all these sites.”
		+
		+	Suggesting proper remedial measures to stop the pollution load from travelling to far off areas where groundwater was currently being extracted for drinking purposes, Shekhar said, “Some reports have shown that landfill sites are polluting the groundwater, but the time has come for us to look for remedial solutions on what should be done to prevent it.”
		+
		+	The DPCC report states that the desired TDS limit for drinking water is 500 mg/l, but it was 5,280 mg/l at Bhalswa, the highest among all three landfill sites. The TDS level was recorded at 2,350 mg/l at Bhalswa Janta Colony and 3,330 mg/l at Bhalswa Dairy. The TDS limit was more than double the desired limit at three locations near Ghazipur landfill site, while the chlorine level was more than 1,500 mg/l at two sites. The level of chlorine was 1,625 mg/l near the Ghazipur entry gate against the desired limit of 250 mg/l. Similarly, the chlorine level was above 900 mg/l at three locations near Okhla landfill site.
		+	The report further stated that hardness through CaCO3 should not be more than 300 mg/l, but it was three times higher at Okhla. The calcium level was the highest in an area near Okhla at 280 mg/l against the desired limit of 75 mg/l. Calcium was higher than the desired limit at four sites each near Ghazipur and Bhalswa.

 The capital, already facing a severe drinking water shortage, is heading towards a more serious situation as the level of groundwater, continuously depleting in the last two decades, has resulted in 90% of the city being categorised as semi-critical or critical.
 Presenting a dismal picture, the Central Ground Water Board told the Supreme Court that the water level has been decreasing from 0.5 metre to over 2 metres per year at different places in Delhi and could lead to a crisis if not halted. Compiling data on groundwater levels from year 2,000 onwards, the board in its report said water levels at all its 20 monitoring stations have seen a steady decline with areas around Chhatarpur, Dwarka and the President’s Estate hit the worst.
 As per the report, 27% of the national capital territory’s 1,483 sq km had ground water at the level of 0-5 metres in 2010 but in 17 years this has shrunk to 11%. In 2000, ground water was available till 40 metres but at present water levels in 15% of Delhi, or around 222 sq km, have plunged to 40-80 metres.
 The board has placed almost all of Delhi in semi-critical or critical zones except a few pockets of west and central Delhi, which have been declared safe as per 2005-10 data. The problem might be serious in NCR because of over-exploitation of ground water for construction.

		+	''Court Takes Note Of Niti Aayog Report; Slams Centre, Delhi Govt''
		+
		+	With Delhi staring at an alarming situation to reach virtually zero groundwater level by 2020, the Supreme Court on Wednesday slammed the Centre and Delhi government for not taking steps and asked them to file response on how to ward off the crisis.
		+
		+	A bench of Justices Madan B Lokur and Deepak Gupta took note of a Niti Aayog report projecting a disturbing picture that no groundwater would be available in Delhi and 21 other major cities by 2020 and asked the authorities concerned to pull up their socks to deal with the impending emergency.
		+
		+	As per the report, nearly half of India’s population could end up with no access to drinking water by 2030. But the water crisis could be worse for some of biggest metros - Delhi, Hyderabad, Bengaluru - which will run out of groundwater as early as 2020, according to the ‘Composite Water Management Index’ (CWMI) report by Niti Aayog.
		+
		+	Central Ground Water Board also projected a very dismal picture and told the apex court that groundwater in the capital has been continuously depleting in the last two decades and now 90 percent of the city has come under ‘critical’ condition.
		+
		+	In a comprehensive report filed in the court, the Board said the water level had been decreasing from 0.5 meter to more than 2 meters per year at different places in Delhi and could lead to a crisis if it is not stalled in the near future.
		+
		+	Compiling the data on groundwater level from 2000 onwards, the Board in its report said water level at all of its 20 monitoring stations witnessed steady decline and areas around Chhatarpur, Dwarka and President’s Estate were the worst hit. It placed almost entire Delhi on ‘semi-critical’ or ‘critical’ zones except a few pockets of West and Central Delhi which have been declared safe as per the 2005-10 data.
		+
		+	Referring to the reports, the bench said government authorities could not ignore the findings and had to act fast as only one and half years are left to avert the catastrophe. The court expressed anguish over the recommendations made by ministry of water resources as it did not mention any concrete suggestion to deal with the problem. It also noted that the Delhi government and Delhi Pollution Control Board did not even bother to file response on the problem as per its order.
		+
		+	It granted four weeks’ time to the Centre to file a comprehensive report spelling out immediate, intermediary and long-term measures to check the depletion of groundwater in the capital.
