Abstract: Water and soil is the most important and crucial factor on the global ecosystems and human health. This study focuses on the physico chemical parameters of effluent water and soil serving as an indicator of Tannery effluent tank, in Dindigul District. Bird census made using total bird count from December 2009 to May 2012 to enumerate bird species composition in the Tannery effluent tank. The study area harbored totally 14 species of birds which is grouped under 9 families falls under 7 orders. The maximum abundance of birds species was from the family Ardeidae and Charadridae. The most dominant species in Tannery Effluent tank was Black-winged Stilt and Little Egret. Water bird species seen abundantly were Black-winged Stilt, Little Egret, Grey Duck and Green Shank. The least number of bird species observed was Large Egret, Little Grebe and Median Egret. Electrical conductivity, total dissolved solids and the level of Chloride, Sulphate, Iron, Ammonia, Nitrate, Phosphate, BOD, COD and DO were high in the effluent water. Fluoride and Nitrite was within the standard limit of effluent water. The accumulation of micro nutrient in soil as Manganese, Zinc, Copper and Iron were high during the study. Determining the bird community in Tannery Effluent Tank and to evaluate the impact of Tannery Effluent Tank on the distribution of birds in Dindigul and the results highlights the discharge of highly polluted waste water effluent from tanneries of Dindigul District.

Abstract: Water quality is one of the most important criteria to ascertain its suitability for human consumption. An investigation was undertaken to study the physical and chemical properties of untreated and treated drinking water at Pannaaipatti purification plant, Theni District, Tamil Nadu. The physico chemical parameters such as pH, total alkalinity, total hardness, turbidity, chloride, sulphate, nitrate, dissolved oxygen, total dissolved solids and conductivity were analysed. The water samples were clear and odourless. All the parameters of the water samples were within the permissible limit as prescribed by the standard water quality parameters for drinking. Comparatively alkalinity, hardness, chloride, chlorine and total dissolved solids of the treated water were higher than the untreated water. Though all the parameters were within the standard permissible limit for drinking, some of the micro nutrients such as fluoride, magnesium and iron concentration were not recorded.
