Macrophytes are important component of the aquatic ecosystem and broad changes in the abundance of individual species and community composition provide valuable information on how and why an ecosystem might be changing. Santhapettai lake is one of the biggest fresh water lake in Villupuram district, Tamil Nadu. The physico-chemical parameters were analysed for one year (October 2012-September 2013). Quadrates were laid randomly and extending from shoreline towards the lake center. The macrophytes falling in each quadrate were sorted species wise, identified and data were recorded. The plants have been identified from fresh materials with the help of different floras. In this present investigation, a total of 33 species belonging to 23 families and 28 genera were identified under algae, pteridophytes, dicotyledons and monocotyledons. Further, the plants were classified in morphological group as floating (7), submerged (1), submerged anchored (13), floating leaved (1) and emergent anchored (11). The coverage/spread of macrophytes along the shorelines was higher compared to the centre of the lakes where the species composition was found reduced. Assessment of biota, continuous monitoring and conservation lake are the important components to safeguard the biological wealth of lentic and lotic freshwater ecosystem.

The present study deals with the statistical analysis of physico-chemical parameters and cyanophycean members of two pond water quality of Chidambaram, Cuddalore district (Tamil Nadu). The qualities of pond water were analyzed for six months. Eleven important parameters were included in statistical analysis. The qualities of pond water have been assessed by calculating mean, standard deviation and correlation coefficient. Correlation studies of hydrobiology with physico-chemical parameters revealed that the relationship between phytoplankton density in general and that of the specific groups are highly complex and often controlled by interactions of different factors. In the both pond water the correlation coefficient test revealed that cyanophycean members positively correlated with temperature, pH, CO2, alkalinity, hardness, nitrate, BOD and COD at 1 % and 5 % level significant, where as it is negatively correlated with acidity and dissolved oxygen. In the present study it can be concluded that the cyanophycean members are highly tolerant organisms. They prefer to grow at higher temperatures and in highly alkaline, BOD and COD waters. Hence they can with stand high levels of contaminated waters of Thillai Kali Kovil pond, when compared to Ilamiyakkinar Kovil pond.

Soil serves as a more reliable index for productivity than water qualities. The productivity of any pond depends largely on the quality of bottom soil that is “store house of nutrients.” The present paper deals with the study of physicochemical parameters like organic carbon, pH, Electrical conductivity, Nitrogen, Phosphorus, Potassium of soil from Muthannan Kulam,Coimbatore (March 2013- May 2013). Analysis for the above parameters indicated contamination of the soil quality due to some anthropogenic activities.

To identify and eliminate the causes of tastes and odors in drinking water,we have developed a new robot-assisted methodology for absolute threshold flavor determination called “up and down”. A study undertaken at an important biological treatment plant in the suburb of Paris (France) over a period of one year, allowed us to compare results from physico-chemical analyses with those of up and down threshold (UDT) values.This work also demonstrated the very important influence of chlorination on water quality.Furthermore, a number of physico-chemical parameters like POX-TOX and THM were shown to be unsuitable for the prediction of UDT values, but chromatographic finger printing after CLSA extraction and ECD detection showed a possible relationship with UDT.In addition, processes involving dechlorination, stripping and ozonation have been developed to remove chlorine-like odors from treated water supplies.

Plankton have immense value as food and play an important role in disposal of sewage and natural purifiers of water. Zooplankton diversity is one of the most important ecological parameter in water quality assessment. In this study we try to assess the seasonal zooplankton species richness and diversity, for a period of One-year (April 2014 – March 2015) data on the seasonal studies of zooplankton diversity of jubilee pond, Chaibasa, West Singhbhum, Jharkhand, India revealed the presence of 29 zooplankton species. A limited number of these were recorded throughout the year, while others were distributed in different seasons mainly in winter and summer seasons. During winter, Cladocerans were the most dominant group followed by Copepoda. On the other hand, rotifers and Cladocerans were the most dominant during summer. Certain species e.g. Brachionus calyciflorus, Brachionus falcatus, Monostyla quadridentatus, Trichotria sp., Cyclops sp., Cypris sp., Daphnia carinata were recorded throughout the year. Physico-chemical analysis of Temperature, pH, dissolved oxygen, free carbon-di-oxide, alkalinity, chlorinity, salinity, total hardness, and phosphorus were observed during the study period.

The present study deals with the physico-chemical parameters and biological diversity of Budhoholi at Sani-Arjun Municipality -7 Jhapa, from July to October, 2015. The physico-chemical properties of water were within the maximum permissible limit with slight variation in some parameters. The biological diversity was found to be rich. Riparian vegetation consisted of 21 herbs 13 shrubs, 11 trees and 4 climbers, 9 aquatic macrophytes and 21 species of fishes. The overall result of the lake indicated that the lake is not disturbed and is not polluted.
