Abstract
The study on Water Quality Assessment of Educational Institutes in Hamirpur District of
Himachal Pradesh was conducted during 2019-2020 in the Department of Environmental Science, Dr.
Y.S. Parmar University of Horticulture and Forestry, Nauni (Solan) Himachal Pradesh. The temperature
of drinking water at various educational institutes on annual basis varied from 19.5 to 28.6oC, pH
from 7.88 to 6.79, EC from 0.47 dS m-1 to 0.19 dS m-1, TDS from 234.17 mgl-1 to 62.93 mgl-1,
BOD from 3.05 mgl-1 to 0.58 mgl-1, COD from 144.33 to 62.17mgl-1. These parameters were
found within the permissible limits as prescribed by BIS and varied with location. The physicochemical
parameters were found higher during the summer season as compared to the winter
season. In drinking water of different educational institutes, the concentration of Cd on annual
basis varied from zero to 0.002, Zn from zero to 0.001, Pb from zero to 0.001, Cu from zero to
0.007, Fe from 0.163 to 0.742, Mn from 0.03 to 0.05 and Ni from zero to 0.015 mg per liter (mg
l-1). The interaction effect of locations and seasons was found significant for all these heavy
metal except Cd for which it was non-significant. The concentration of all the heavy metal was
observed higher during the summer season compared to winter at all the location but was within
the permissible limits as prescribed by BIS. Therefore, more care is required towards the supply
of drinking water of these institutes during the summer season to avoid the spread of any water
borne diseases and illness in the study area in particular and in whole state in general.
