Abstract
Ameenpur Lake, the Biodiversity Heritage Site of India is the first urban lake to
be given the status of a heritage site by the National Biodiversity Authority of
India in the year 2016. In the present study, the water quality of Ameenpur Lake
has been carried out using GIS technology. The water samples were collected during
Pre-Monsoon, Monsoon and Post-Monsoon seasons of the year 2019-20 and analysed for
various physico-chemical parameters such as pH, Electrical Conductivity, Total Dissolved
Solids, Turbidity, Total Hardness, Total Alkalinity, Calcium, Magnesium, Sodium,
Potassium, Chloride, Sulphates, Carbonates, Bicarbonates, Fluorides, Phosphates,
Nitrates, Dissolved Oxygen, Chemical Oxygen Demand and Biological Oxygen Demand
in the laboratory using American Public Health Association1 standard methods for
water and wastewater treatment. Obtained results were compared with Bureau of Indian
Standards.
The results indicate that lake water is slightly alkaline in nature and most of
the parameters were exceeding the permissible limits in all the three seasons. Statistical
analysis has been used to calculate the correlation coefficient of different parameters.
The correlation matrix shows that total alkalinity has significant correlation with
calcium and magnesium, EC with chlorides, nitrates and fluorides, total hardness
with calcium, magnesium, bicarbonates and total alkalinity and bicarbonates with
calcium.
