Freshwater has a significant role in determining the ecological environment, public health
and socio-economic development. This study analyzed the spatio-temporal variation in
surface water quality of the tropical reservoir Mettur, India, to determine whether its water
is suitable for human consumption and aquatic ecosystem. Thus, 21 water quality parameters
were monitored seasonally (pre-monsoon, monsoon and post-monsoon) at nine sampling
sites covering riverine, transitional and lacustrine zones of the reservoir during 2018. The
study revealed spatial variation, which was due to input from industrial and domestic
wastewater in the lacustrine zone of the reservoir. However, temporal variability often
exceeded spatial variability. The factor analysis indicates that basin geology, anthropogenic
stress and agricultural applications simultaneously act vital roles in deciding the reservoir
water quality. Based on similarity of water quality parameters, cluster analysis grouped all
the nine sampling sites into three clusters of high, moderate and less polluted sites. Correlation
analysis also indicated that multiple sources influence the reservoir water quality
during all the seasons. Based on BIS and WHO values, the calculated water quality index
(134–158) indicates that water of the reservoir is not fit for human consumption, while the
trophic state of this reservoir is moderately-eutrophic to eutrophic. However, with precaution,
this aquatic body seems to be suitable for aquatic life and fish growth. The overall water
quality deterioration of this reservoir indicates a strong need for development of a regular
monitoring system for implementation of an effective management system to safeguard
human and environmental health.
