People of Orissa have been involved in the protection of some unique and endangered wildlife for their own interest or for the environmental sustainability. Rugudipalli is one of the community based conserved areas of Orissa where the arrival of Asian Open Bill Storks is believed to coincide exactly with the advent of monsoon season in Orissa.

The study aims at analyzing the physico-chemical parameters of pond water (pre and post monsoon season) in Vadodara city and calculate water quality index.

Physico-chemical characteristics of Rajakkamangalam estuary situated in Kanyakumari district of Tamil Nadu and its sediment samples were collected in 4 sampling stations in 2001.

In this present work various physico-chemical parameters and diversity of plankton were analysed for a period of 7 month from August 2009 to February 2010. The pond was highly polluted with discharge of many pollutants from domestic sewage, industrial waste and thus the chemical parameters of the pond were noticed to fluctuate and showed adverse effect on the diversity of plankton.

In the present paper water quality of eastern Doon Valley was assessed. The evaluation of water quality of different localities of Raipur block was studied in the different months throughout the year.

Ground water samples were collected from different locations in and around Tiptur town, Tumkur District, Karnataka and analyzed for their physico-chemical characteristics.

In the present study an attempt has been made to determine the physico-chemical status of Harike lake located on the confluence of Satluj and Beas rivers.

The present paper deals with the characterization of solid waste. During the study period Chitrakoot Nagar Panchayat, the MSW composition was found as polythene (10.12%), plastic (4.78%), rubber (3.70%), metals (2.84%), glass (4.08%), wood (5.55%), cotton and cloths (4.29%), paper and cardboards (7.77%), vegetable wastes (11.66%), soil and constructional wastes (29.87%), garden waste (9.73%), rags (2.29%) and ash (3.32%).

This paper addresses the effect of pollution on dissolved oxygen content (DO) in a Shivalik Himalayan stream during early hours of day in the summer season (May 2009-June 2010). The study showed that the dissolved oxygen in the stream is below 4 mg/L in a stretch of 2600 m and, therefore, water is not fit for public supply, bathing, wildlife and fish culture.

Electrical resistivity studies at 56 locations in an around Muddanur area has been carried out. The main lithological units in the study area are quartzites, shale and limestones. The data were interpreted with the help of master curves and auxiliary point charts. The study reveals that the weathered and fractured portions in shale and limestone that occur in the central portion of the study area constitutes the productive water bearing zones classified as good groundwater potential zones.
