Abstract
Pennar is one of the major rivers in south India and it has significant impact on water chemistry. This investigation intended to assess the water quality parameters of Pennar river estuary, Nellore, South East coast of India. A total of 20 bottom water samples were collected from chosen sample points during February 2020 and evaluated at fortnightly intervals to acquire baseline information on the estuarine water quality. Significant variations were observed in physicochemical parameters of water at different stations and these are as follows: pH (7.29–8.47), bottom water temperature (28.8–31.8 °C), air temperature (32.9–30.1 °C), EC (44.24–53.54 μmho/cm), Dissolved Oxygen (3.7–4.6 mg /l), Organic Matter (0.61–1.7 mg/l), Salinity (29.24–35.93 ppt), Nitrates (1.4–2.2 mg/l), and Sulphates (120–192 mg/l), respectively. Multiple statistical techniques such as Pearson Correlation Analysis, Factor Analysis (FA), and Hierarchical Cluster Analysis (HCA)were effectuated to the obtained datasets to determine the relationship among the selected parameters.
