Assessment of Surface Water Quality of Wadhwana Irrigation Reservoir, Gujarat, India

Abstract

A

Assessment of seasonal variation in surface water quality is important for evaluating the
limnological changes in a reservoir. The present study was carried out in Wadhwana
irrigation reservoir for understanding changes in different physico-chemical parameters of
water quality from July 2016 to May 2017. The values of selected physico- chemical
parameters were observed to vary considerably as per the seasons for pH (7.02-
8.85),Temperature (12.80 ºC -33.00ºC),Electrical Conductivity (0.29 mS-14.15 mS), Dissolved
Oxygen (4.30 mg/l-8.71 mg/l),Turbidity (3.70 NTU-91 NTU), Acidity (20 mg/l as CaCO3-80
mg/l as CaCO3), Alkalinity (80 mg/l as CaCO3-280 mg/l as CaCO3), Chlorides (1.2 ppt -10
ppt), Salinity (0.04 ppt-18.06 ppt), Total hardness (200 mg/l as CaCO3-600 mg/l as CaCO3),
Calcium hardness (21 mg/l as CaCO3-105 mg/l as CaCO3), Magnesium hardness (104 mg/l as
CaCO3-600 mg/l as CaCO3) and Nitrates (0 mg/l -42.30 mg/l) on other hand, seasonal
variations were observed to be insignificant for the nutrients like Nitrites (0.01 mg/l -0.18
mg/l) and Phosphates (0.03mg/l -2.90mg/l). Temperature and Electrical Conductivity were
found to be high during summer season; Turbidity, Acidity, Alkalinity, Total hardness,
Magnesium hardness, Nitrates and Nitrites were high during monsoon season whereas pH,
Dissolved Oxygen, Calcium hardness, Chlorides and Salinity were high during winter season.
The present study revealed that water of Wadhwana Irrigation Reservoir is suitable for
fisheries, irrigation and drinking purposes.
