Basin Sub Basin Inventory of Water Pollution - The Ganga Basin Part One
: The Yamuna sub - basin

                                               Foreword
It would be rather ambitious and hardly practicable to restore and maintain all waters at the pristine quality. Planning pollution-control activities to attain such a goal is bound to be deterrent to developmental activities and also cost-prohibitive. Natural waters have got to be used for various competing as well as conflic- ting activities. Therefore, the aim has been to restore and maintain waters at various places to such qualities as are needed for their designated best-uses. With this objective the Central Board for the Prevention and Control of Water Pollution has undertaken the task of river basinwise pollution potential assessment to frame control management programmes and the information available is disseminated through the Assessment and Development Study of River Basin Series (ADSORBS).

The present publication is the second in the ADSORBS series and brings to the fore the basin-wise pollu- tional studies conducted in the Ganga

which has held India 's heart captive and drawn uncounted millions to her banks since the dawn of history. Part I of the present treatise covets the river Yamuna, a major tributary of the Ganga and would be followed by Part II which would coveF the entire Ganga Basin excluding the Yamuna Sub-basin. It is believed that this report would be found useful to the agencies participating in the work of restoring and preserving the quality of natural water bodies, and would serve as a model for conducting similar studies in the other major river basins in the country.

The data in support of this report have been scrutinized, processed and compiled by Km. Usha Madan and Shri S. K. Agrawal under the overall supervision of Dr. R. N. Bhattacharyya. Dr. G. D. Agrawal as Con- sultant, analysed the data and enriched the report with cFitical and analytical approach which helped in deriving the major recommendations for implementation of pollution control. Appreciation is also due to Dr. S. P . Chakrabarti for his association in finalising the report. Shri Bidhi Chand took the overall responsibility for typing the manuscript.

The Central Board also acknowledges the co-operation of the Center for Study of Man & Environment, Calcutta in preparing the final maps and also in printing of the report. The base year of all the statistical data used in this report is 1975-76.
