Quality Monitoring - an Indian Experience

Foreword
The present volume is the fifteenth publication
of the series (ADSORBS) on assessment and development study of river
basins in India undertaken( by the Central Board for the Prevention
and Control of Water Pollution.lt is devottid to the study of the
current status of pollution in the Subarnarekha basin.
Though the Subarnarekha basin is the smallest of the 14 major river
basins of India draining an area of 19,296 square kilometres and
covering hardly 0.6 percent of India's land surface, yet it is an
important inter-Stat~ river flowing through one of the most important
industrial belt and mineral-rich areas of India. The basin therefore
n~eds careful envlronmenta1 management planning.
Having completed the study of the Ganga basin in three vo.umes,
the Centerfor
Study of Man and Environment was commissioned for" the present

between
different aspects of economic activities within the basin and the
resultant water quality in the Subarnarekha river. The Subarnarekha
and its major tributaries have been classified into segments on the
basis of designated best use of the stream water, thereby laying down
the current minimum levels of water quality requirements for different
stream segments. The Subarnarekha in its upper and middle sections
is now highly polluted, as has been observed in this study based on
the water qua lity data collected by the Bihar State Pollution Control
Board. Finally, an action programme has been suggested here integrating
water reasource plan and water quality management within the Subarnarekha
basin.
The data base for socio-economic information incorporated in this
volume generally relates to 1981 situation. The stream water quality
data used here, however, concern a longer period from 1979 to 1985.
It is obvious that preparation of a comprehensive report like the
present one requires cooperation of different Central and State Government
organizations and relevant statutory bodies. In this regard, the Central
Board recognizes the cooperation received from the State Pollution
Control Board of Bihar in particular as also from those of Orissa
and West Bengal.
The Center for Study of Man and Environment was entrusted with the
difficult task of collection of information from the States, analysis
of the data, and final preparation of the report along with the drafting
and preparation of the multicoloured maps appended with ~his volume.
The Center saw through the final print ing of the report as well.
The Central Board acknowledges the service thus rendered by the Center
for Study of Man and Environment. particularly by Shri S. P. Das Gupta
(Editor and Chief Coordinator), Professor A. K. Saha and Shri A. B.
Biswas of the Center.
This report has been prepared in the hope that the recommendations
and action plan put forward here would go a long way to help set up
a suitable environment management authority for ecological development
and pollution abate ment in the Subarnarekha basin. |
