| Status
and Trend of Water Quality of River Ganga (1983-89) |
| Foreword
TThe River Ganga
is part of the life of millions of people through the ages along its entire course
from its origin at Gangotri in the Himalayas to its confluence with the sea in
the Bay of Bengal. The river is put to several uses ranging from drinking, bathing,
propagation of fisheries and wildlife, agriculture besides serving as a recipient
of both domestic and industrial discharges from many towns/cities on its banks.
The Central Pollution Control Board has brought out in the past a comprehensive
basin report ADSORBS/7/1982-83 on the river Ganga. Based on the report the Gahga
Action Plan (GAP) was prepared in the year 1984 followed by the establishment
of Central Ganga Authority (CGA) to implement the GAP.
The Central Board
has been conducting water quality monitoring on this river since 1979 at 43 locations
under its Monitoring of Indian Aquatic Resources (MINARS) programme. However,
there has been a slight change after CGA |
|
came into
being with water quality being currently monitored at 27 locations under GAP spread
over the three states ut tar Pradesh, Bihar and West Bengal. The three State Pollution
Control Boards (SPCBs) conduct the sampling and water analysis.
The central
Pollution Control Board receives, water quality data from the SPCBs, compiles
& analyses these data. since water quality data upto 1982 has already been discussed
in CPCBs report ADSORBS/7/1982-83 in the present report, the water quality status
of the river is presented graphically and in the form of statistical tables based
on the data collected between the period 1983-1989.
The participation
and co-operation extended by the State Pollution Control Boards is gratefully
acknowledged.
This
report containing about 150 graphs along with the statistical tables provide a
comprehensive view of the quality of the R. Ganga. |
