Abstract : Water quality index (WQI) is valuable and unique
rating to depict the overall water quality status in
a single term that is helpful for the selection of
appropriate treatment technique to meet the
concerned issues. The present work aims at
assessing the water quality index (WQI) in the
surface waterbodies (Ambazari, Futala and
Gandhisagar lake) situated in Nagpur city,
Maharashtra, India, by monitoring five sampling
locations within all lake ( viz. Inlet1, inlet2, centre,
corner and outlet) for a period of 3 months from
August to October-2014. (pre-immersion,
immersion and post-immersion period) For
calculating the WQI, 14 parameters, namely, pH,
electrical conductivity, total dissolved solids, total
hardness, alkalinity, calcium, magnesium, sodium,
potassium, chloride, sulphate, nitrate, fluorides
and iron were considered. It is apparent from
WQI values that all studied lake water with WQI
values ranging from 42.28 to 169.37 especially
Futala lake (55.81 to 169.37), Ambazari lake
(42.28 to 109.66) and Gandhisagar Lake (60.82 to
120.10) falls under poor water category. It is
observed that the values of physicochemical
parameters significantly increased during the
immersion period and then declined in the post-
immersion period, however the general
trendobserved was : immersion > post –
immersion > pre-immersion values. The present
study revealed that all studied lake water are
polluted (due to surface run-off, bathing activities,
agriculture run-off, effuents from upstream from
surrounding industrial and garden area,
immersion of idols of God and Goddess during
festival season) and is unsuitable for human
consumption, irrigation, industrial purpose also
for the survival of life forms unless treated
properly.
Keywords: Physicochemical analysis, WQI, lake,
water pollution, festivals, surface water.
