Krishnan Marg, New Delhi - 12 FOREWORD The River Yamuna, the largest tributary of River Ganga has been one of the most prominent & important rivers of India. Unfortunately, certain stretches of River Yamuna are very polluted. Various urban centers e.g. Delhi, Mathura, Agra etc., which are located on the banks of Yamuna river, draw fresh river water for various activities. In return, almost the entire wastewater generated by these centers is disposed off into the river. This is the prime reason for deterioration of Yamuna River water quality from urban agglomeration of Delhi up to Chambal River Confluence. The objectives of the monitoring studies undertaken for water bodies are to assess variation in water quality with time, significance of various outfalls into water bodies, effectiveness of various steps undertaken for pollution abatement etc. With these objectives, Central Pollution Control Board is regularly monitoring the entire Yamuna river stretch alongwith major polluting sources since 1976. Several reports had already been published based on these monitoring studies. A project related with monitoring of Yamuna water quality under Yamuna action plan has been assigned to CPCB by National River Conservation Directorate (NRCD), Ministry of Environment & Forests. The present report covers the findings of studies under NRCD project and National Water Quality Monitoring Programme of CPCB. The water quality status of River Yamuna presented in this report is for the period 1999- 2005. It is believed that this report would be useful to various agencies engaged in the work of restoring and preserving the water quality of Yamuna River. (V.

The total basin area of the river is 366223 km2 which covers part of geographical area in the states of Uttaranchal, Uttar Pradesh, Himachal Pradesh, Haryana, Rajasthan, Madhya Pradesh & NCT – Delhi. ¾ The flow of the Yamuna River varies significantly during monsoon and non- monsoon seasons. The river constitutes maximum flow i.e. around 80% of the total annual flow during monsoon period. During non-monsoon period the Yamuna cannot be designated as a continuous river but segregated into four independent segments due to the presence of three barrages from where almost the entire water is being diverted for various human activities. ¾ The river water is used for both abstractive and in stream uses. Irrigation is the important use of Yamuna Water followed by domestic water supply, industrial and other uses. ¾ The sources contributing pollution are both point & non-point type. Urban agglomeration at NCT – Delhi is the major contributor of pollution in the Yamuna River followed by Agra and Mathura. About 85% of the total pollution in the river is contributed by domestic sources. The condition of river deteriorate further due to abstraction of significant amount of river water, leaving almost no fresh water in the river, which is essential to maintain the assimilation capacity of the river. ¾ About 580 km long river stretch in between Wazirabad barrage and Chambal river confluence is critically polluted. This stretch is characterized by high organic contents, high nutrients, significant depletion or increase in dissolved oxygen, severe odours etc. The 22 km long Delhi stretch is polluted severely. ¾ Central Pollution Control Board is regularly monitoring River Yamuna at 19 locations alongwith its main tributary, the Chambal River at Udi. Twenty eight major drains outfalls into Yamuna are also being monitored to measure the pollution load contributed by these drains into the river. ¾ This report covers the findings of monitoring studies undertaken between the periods from 1999 to 2005. ¾ Though, there was gradual increase in organic pollution from origin till the river reaches Delhi, but the water quality is quite good in this stretch of river. The organic pollution level increase significantly at Delhi and BOD level does not confirm the standard till the confluence of river Chambal. ¾ In the critically, polluted stretch of Yamuna river from Delhi to Chambal confluence, there was significant fluctuations in dissolved oxygen level from Nil to well above saturation level. This reflects presence of organic pollution load and persistence of eutrophic conditions in the river. ¾ Bacteriological contamination is significantly high in the entire Yamuna River stretch. Total Coliforms are generally well above the prescribed water quality standard even sometimes at Yamunotri also.
