Chennai formerly known as Madras, is the capital of the state of Tamil Nadu and India's fourth largest metropolitan city. The status of the groundwater depends on a large number of individual hydro-biological parameters. Pollutants are added to the groundwater system through anthropogenic activities and natural processes. Solid waste from industries is being dumped near the factories and subjected to reaction with percolating rainwater and reaches the groundwater level. The percolating water picks up a large amount of dissolved constituents and reaches the aquifer system and thus it contaminates the groundwater. The aim of the present study was carried out to assess the status of the groundwater in Chennai city using physicochemical and biological parameters according to the standard methods (APHA 1998). Two zones (North and South) from Chennai city were selected for the studies from each Zone 25 sampling stations were fixed and the analysis was made during summer and monsoon seasons (Jan - Dec) 2007. Results indicate that the groundwater of the study area is bacteriologically not safe and need treatment before it is used for drinking purposes. Thus, this study assumes greater importance in the public health management point of view.Keywords

Species composition, density and diversity of tintinnids along with hydrographical parameters in Muttukadu backwaters (Lat. 12°47'N, Long. 80°15' E), South East coast of India were studied from February 2004 to May 2006. Fifteen species of tintinnids were recorded and among them, Favella ehrenbergi and Favella philippinensis were dominant during the study period. The observed maximum population density of tintinnids were 1,58,500 ind/m3 at location 1 during postmonsoon season in February 2006 may be due to the higher levels of salinity (ppt) and the higher peak in physicochemical parameters observed in postmonsoon seasons during the study period. The richness of phytoplankton showed their higher productivity and population density during 2005 in all the seasons after tsunami event.Keywords

Among zooplankton, copepod community in Muttukadu backwater was investigated in detail during February 2004 and May 2006. A total of 41 species of copepoda belonging to 22 genera under three suborders Calanoida (17), Cyclopoida (15) and Harpacticoida (09) along with nauplii and copepodites were recorded. In this paper, the monthly and seasonal abundance of copepod fauna is reported from four locations of Muttukadu backwater and total mean abundance was compared among those locations. The seasonal data showed higher abundance during pre-monsoon season. The fluctuations in abundance of copepoda observed during the study were discussed in detail.Keywords

The present paper is prepared from the data collected during different seasons from February 2004 to May 2006. An attempt is made to enumerate the rotifer diversity of Muttukadu Backwaters located at 36 km away from Chennai city. Plankton samples were collected from the four sampling sites and the distribution of rotifers was noted. We examined the structure of rotifera in terms of occurrence and abundance at each locations to note the difference. Totally 19 genera and 34 species of rotifera belonging to three major orders Ploimida, Gnesiotrocha and Bdelloidea represented from 11 different families along with the rotifer eggs were recorded from the study area. The total mean abundance of different families was compared among the four locations showed the higher abundance during pre-monsoon season. The fluctuations in abundance of rotifera during the study period were noticed.Keywords
