Water quality assessment in the River Godavari, Near Manthani, Telangana.

Abstract

The present paper deals with the assessment of water quality in the river Godavari, near Manthani, Telangana. The water samples were collected for a period of 18 months (May 2017- October 2018) to assess the quality of water. The assessment of water quality has been made in the river Godavari on the basis of physico-chemical and phycological characteristics. In the former a number of anions, cations and other parameters have been estimated in the river water samples. Benthic algae were taken into consideration under phycological parameters. The algae were analysed quantitatively and quantitatively for different groups. The percentages of various groups are also been calculated. The results are compared with standards given by WHO and ISI for water quality. In the river Godavari four groups of algae Bacillariophyceae, Cyanophyceae, Chlorophyceae and Euglenophyceae were encountered. Bacillariophyceae were dominant at all the stations followed by Chlorophyceae, Cyanophyceae and Euglenophyceae. The maximum growth of diatoms was recorded during winter, minimum numbers were attained during summer and rainy season. From the data obtained it is concluded that the parameters analysed are within the permissible limits of drinking water standards in the river investigated.
