Foreword
Water Quality Monitoring is an expensive, time consuming and tedious
exercise. Due to lack of background data, most of the carefully
drawn monitoring programme often turn out to be either over or under
representative. Thus to get optimum result the monitoring programme
need to be reviewed at regular interval.
The Water Quality Monitoring Programme sponsored by the Central
Pollution Control Board comprises of 480 stations. The monitoring
is conducted on monthly or quarterly basis to analyse 24 parameters.
To cover the maximum geographical area and the water bodies, it
is imperative to review the monitoring programme so tnat the monitoring
stations could be shifted from redundant sites. Also the parametric
list and the monitoring frequency could be optimised

The
present report covers the review exercise undertaken for Rationalisation
and Optimisation of Monitoring Programme for River Cauvery .As per
the existing monitoring programme, River Cauvery is monitored at 20
sites with a monthly frequency and for 24 parameters. The study revealed
that monitoring sites could be reduced to 15 from 20 and the frequency
from 12 per year to 8 per year, without loss of information. Also
9 parameters could be deleted from the existing list while 5 additional
parameters cou1d be added to comprehend the parametric list. As per
the recommended programme, the expenditure on monitoring of River
Cauvery could be reduced by 50%.
Mrs.Usha Ghosh with the assistance of Shri A.K.Sinha, Smt.Shashi Goel
and Mr. Jawed Manzar undertook the study.
I think this study could be used as a moder for undertaking similar
studies for other rivers. |
