(Civil) No. 725/1994, titled as News Item Published in Hindustan Times titled ‘And Quite Flows the Maily Yamuna’; directed- - “Central Pollution Control Board to submit a report before this Court as to how many STP are working to their optimum capacity and whether the treated affluent or domestic discharge is again put back into the main polluted drain.” - “The Board to inform the Court as to the measures that can be directed to be taken by the concerned authorities in order to ensure that the treated discharge/affluent is not put back into the polluted drains. The team, which shall visit and inspect the sites, in terms of orders of this Court and submit a report thereto, shall consist of Member Secretary of the Central Pollution Control Board and the Chief Engineer of the Delhi Jal Board” Central Pollution Control Board submitted the Interim report on “River Yamuna- Wastewater Management Plan in Delhi” to Hon’ble Supreme Court of India on 9th November, 2012. The Hon’ble Court in its order dated 09/11/2012 further order and directed- - “At the request of the learned counsel , we grant him three weeks' time to complete the joint inspection. Let the final inspection report be filed before this Court within the aforesaid period.” - “We make it clear that we expect definite suggestions from the Joint Committee in regard to providing of proper drainage system as well as the manner in which the pollution of Yamuna can be controlled and it will be converted from Maily Yamuna to Clean Yamuna, in the larger interest of the public.” 2.0 INTRODUCTION 2.1 AREA The National Capital Territory of Delhi is spread over an area of 1,483 km2 out of which 783 km2 (302 sq mi) is designated rural and 700 km2 urban. There are three local bodies managing the affairs in Delhi namely, Municipal Corporation of Delhi (area of 1,397.3 km2), New Delhi Municipal Committee (area of 42.7 km2) and Delhi Cantonment Board (area of 43 km2) 1 2.2 POPULATION Delhi is the eighth largest metropolis in the world by population with 1, 67, 53,235 inhabitants as per the 2011 Census. There are nearly 22.2 million residents in the greater National Capital Region urban area (which also includes Noida, Greater Noida, Ghaziabad, Gurgaon and Faridabad along with other smaller nearby towns). The name Delhi is often used to include urban areas near the NCT, as well as to refer to New Delhi, the capital of India, which lies within the metropolis.

  • Bird Species in Delhi-“Birdwatching” Tourism
    Conference Proceedings: 2 nd International Scientific Conference ITEMA 2018 BIRD SPECIES IN DELHI-“BIRDWATCHING” TOURISM Zeba Zarin Ansari 63 Ajay Kumar 64 Anton Vorina 65 https://doi.org/10.31410/itema.2018.161 Abstract : A great poet William Wordsworth once wrote in his poem “The world is too much with us” that we do not have time to relax in woods and to see birds chirping on trees. According to him we are becoming more materialistic and forgetting the real beauty of nature. Birds are counted one of beauties of nature and indeed they are smile giver to human being. When we get tired or bored of something we seek relax to a tranquil place to overcome the tiredness. Different birds come every morning to make our day fresh. But due to drainage system, over population, cutting down of trees and many other disturbances in the metro city like Delhi, lots of species of birds are disappearing rapidly. Thus a conservation and management system need to be required to stop migration and disappearance of birds. With the government initiative and with the help of concerned NGOs and other departments we need to settle to the construction of skyscrapers. As we know bird watching tourism is increasing rapidly in the market, to make this tourism as the fastest outdoor activity in Delhi, the place will have to focus on the conservation and protection of the wetlands and forests, management of groundwater table to make a healthy ecosystem, peaceful habitats and pollution-free environment for birds. Delhi will also have to concentrate on what birdwatchers require, including their safety, infrastructure, accessibility, quality of birdlife and proper guides.

  • Current Condition of the Yamuna River - an Overview of Flow, Pollution Load and Human Use
    Current condition of the Yamuna River - an overview of flow, pollution load and human use Deepshikha Sharma and Arun Kansal, TERI University Introduction Yamuna is the sub-basin of the Ganga river system. Out of the total catchment’s area of 861404 sq km of the Ganga basin, the Yamuna River and its catchment together contribute to a total of 345848 sq. km area which 40.14% of total Ganga River Basin (CPCB, 1980-81; CPCB, 1982-83). It is a large basin covering seven Indian states. The river water is used for both abstractive and in stream uses like irrigation, domestic water supply, industrial etc. It has been subjected to over exploitation, both in quantity and quality. Given that a large population is dependent on the river, it is of significance to preserve its water quality. The river is polluted by both point and non-point sources, where National Capital Territory (NCT) – Delhi is the major contributor, followed by Agra and Mathura. Approximately, 85% of the total pollution is from domestic source. The condition deteriorates further due to significant water abstraction which reduces the dilution capacity of the river. The stretch between Wazirabad barrage and Chambal river confluence is critically polluted and 22km of Delhi stretch is the maximum polluted amongst all. In order to restore the quality of river, the Government of India (GoI) initiated the Yamuna Action Plan (YAP) in the1993and later YAPII in the year 2004 (CPCB, 2006-07). Yamuna river basin River Yamuna (Figure 1) is the largest tributary of the River Ganga. The main stream of the river Yamuna originates from the Yamunotri glacier near Bandar Punch (38o 59' N 78o 27' E) in the Mussourie range of the lower Himalayas at an elevation of about 6320 meter above mean sea level in the district Uttarkashi (Uttranchal).

  • Hydrogeological Characterization and Assessment of Groundwater Quality in Shallow Aquifers in Vicinity of Najafgarh Drain of NCT Delhi
    Hydrogeological characterization and assessment of groundwater quality in shallow aquifers in vicinity of Najafgarh drain of NCT Delhi Shashank Shekhar and Aditya Sarkar Department of Geology, University of Delhi, Delhi 110 007, India. ∗Corresponding author. e-mail: [email protected] Najafgarh drain is the biggest drain in Delhi and contributes about 60% of the total wastewater that gets discharged from Delhi into river Yamuna. The drain traverses a length of 51 km before joining river Yamuna, and is unlined for about 31 km along its initial stretch. In recent times, efforts have been made for limited withdrawal of groundwater from shallow aquifers in close vicinity of Najafgarh drain coupled with artificial recharge of groundwater. In this perspective, assessment of groundwater quality in shallow aquifers in vicinity of the Najafgarh drain of Delhi and hydrogeological characterization of adjacent areas were done. The groundwater quality was examined in perspective of Indian as well as World Health Organization’s drinking water standards. The spatial variation in groundwater quality was studied. The linkages between trace element occurrence and hydrochemical facies variation were also established. The shallow groundwater along Najafgarh drain is contaminated in stretches and the area is not suitable for large-scale groundwater development for drinking water purposes. 1. Introduction of this wastewater on the groundwater system is even more profound. There is considerable contam- The National Capital Territory (NCT) of Delhi ination of groundwater by industrial and domestic (figure 1) is one of the fast growing metropoli- effluents mostly carried through various drains tan cities in the world.

  • Metal Fractionation Study on Bed Sediments of River Yamuna, India C.K
    ARTICLE IN PRESS Water Research 38 (2004) 569–578 Metal fractionation study on bed sediments of River Yamuna, India C.K. Jain National Institute of Hydrology, Roorkee 247 667, India Received 26 June 2002; received in revised form5 June 2003; accepted 22 October 2003 Abstract The pollution of aquatic ecosystem by heavy metals has assumed serious proportions due to their toxicity and accumulative behavior. The toxicity and fate of the water borne metal is dependent on its chemical form and therefore quantification of the different forms of metal is more meaningful than the estimation of its total metal concentrations. In this study fractionation of metal ions on bed sediments of River Yamuna has been studied to determine the eco-toxic potential of metal ions. The investigations suggest that copper have a tendency to remain associated with residual, reducible and carbonate fractions. The Risk Assessment Code reveal that about 30–50% of lead at most of the sites exist in exchangeable fraction while 30–50% of cadmium at almost all the sites is either exchangeable or carbonate bound and therefore comes under the high risk category and can easily enter the food chain. Most of the copper is in immobile fraction at Delhi while at other sites, a sizable portion (10–30%) is found in carbonate fraction thus posing medium risk for the aquatic environment. Fractionation pattern of zinc shows low to medium risk to aquatic environment. r 2003 Elsevier Ltd. All rights reserved.

  • E-Flow) in River Yamuna
    Environmental flow (E-Flow) in river Yamuna Context: The Hon’ble NGT in its judgment dated 13 January 2015 and through subsequent directions in OA No 6 of 2012 and 300 of 2013 given directions for the maintenance of requisite environmental flow in river Yamuna downstream of the barrage at Hathnikund in Haryana and at Okhla in Delhi so that there is enough fresh water flowing in the river till Agra for restoration of the river’s ecological functions. The Hon’ble Supreme Court had in W.P. ( C ) 537 of 1992 directed on 14 May 1999, that “a minimum flow of 10 cumecs (353 cusec) must be allowed to flow throughout the river Yamuna”. The report of the three member committee of MoWR, RD and GR on Assessment of Environmental Flows (E-Flows) has in March 2015 determined scientifically that E Flows as % of 90% dependable virgin flow at downstream Pashulok Barrage, Rishikesh on river Ganga should be 65.80%. It may be noted that the situation of river Yamuna at the Hathnikund barrage in Haryana is comparable to the situation at Rishikesh on river Ganga. In addition river Ganga at Rishikesh carries far more virgin flow in it as compared to leaner river Yamuna at Hathnikund. E – Flow in river Yamuna In view of the above it has been estimated that the E Flow in river Yamuna downstream of the barrage at Hathnikund should be no less than 2500 cusec (around 70% of the average minimum virgin flow of 3500 cusec reported at Hathnikund barrage during the leanest month of January).

    P: ISSN No. 2231-0045 RNI No. UPBIL/2012/55438 VOL. -6, ISSUE-3, February-2018 E: ISSN No. 2349 - 9435 APeriodic…..A…. Research Study of Abundance and Diversity of Phytoplankton at z- Minor of Gang Canal in Sriganganagar, Rajasthan, India Abstract Phytoplanktons are assemblages of heterogeneous microscopic algal forms whose movement is more or less dependent upon water currents. The present study was undertaken to explore the effect of different seasons on abundance and diversity of phytoplankton in one sites i.e. z-minor of gang canal in Sriganganagar, Rajasthan, India. The present observations were made for a period of fifteen months from September, 2012 to November, 2013 and covering all the seasons. The flora was identified by following standard taxonomic keys and illustrations. The identified phytoplankton belonged to four different families of Chlorophyceae, Bacillariophyceae and Myxophyceae and Xanthophyaceae. The phytoplankton comprises of 16 species belonging to 15 genera. Out of these, 8 species belong to Bacillariophyceae, 5 to Chlorophyceae, 2 to Myxophyceae and 1 to Xanthophyceae. The family Bacillariophyceae was dominating the canal with much abundance throughout the study period. Both the number of genera and number of Manjeet Jaitly species belonging to each genera was maximum in case of family Research Scholar, Bacillariophyceae followed by Chlorophyceae, Myxophyceae and Deptt.of Zoology, Xanthophyaceae. Maximum population abundance of Phytoplakton was Govt. Dungar College, observed in the summer season followed by winter and rainy. Bikaner, Rajasthan Keywords: Phytoplankton, Z- Minor, Gang Canal, Sriganganagar. Introduction The word plankton is derived from the Greek planktos, meaning wandering. It is used to describe the small, usually immotile, freely floating organisms living in aquatic habitats (Powell et al., 1975).
