In the present study different water quality parameters i.e. physico-chemical, heavy metals, haloalkanes, pesticides & most probable number of bacteria were analyzed in pre-monsoon, during monsoon & post monsoon season. The study area selected was Narayangiri Filtration Plant in Bhopal city.

Groundwater recharge and base flow using different investigated methods are simulated in the 15-ha Bukmoongol small-forested watershed located at the southern part of Korea. The WHAT system, PART, RORA, PULSE, BFI, and RAP software are used to estimate groundwater recharge or base flow and base flow index from the measured streamflow.

Carbon dioxide (CO2) is the principal man-made greenhouse gas and the primary atmospheric component of the global carbon cycle. Precise ground-based measurements of CO2 made since the late 1950s indicate that the atmospheric CO2 concentration has increased from ~310 to over 380 parts per million (ppm) over this period [1].

The survey revealed the fact that in India, alum is used for the improvement of effluent quality but the work on alum recovery and reuse is fragmentary. Therefore this work emphasized on recovery of alum from sludge and its reuse for waste water treatment. Various methods have been reported for treatment and disposal of alum sludge.

The present study deals with statistical analysis of physico-chemical parameters of ground water quality in Nambiyar river basin. The quality of ground water has been assessed by using correlation coefficient (r) between all parameters. A systematic correlation and regression study showed linear relationship among different water quality parameters.

When presenting its thematic strategy on air pollution three years ago, the European Commission failed to come up with proposals for specific action to reduce air pollutant emissions.

A new study, co-funded by NASA, has identified a link between a warming Indian Ocean and less rainfall in eastern and southern Africa. Computer models and observations show a decline in rainfall, with implications for the region

This research aims to investigate change and transformation of open pastoral social-ecological systems in Mongolia and develop climate change adaptation options for pastoral communities with participation of herders, local and national governmental officers and scientists.

The present study was taken up during 2007-08 in the state of Andhra Pradesh. Stratified random sampling was adopted to select the respondents. A total of 480 respondents were selected from 16 villages across four mandals of the East Godavari district. The selected mandals are predominantly shrimp farming areas, with optimum salinity and excellent irrigation facilities.

The removal of fluoride from synthetic sample by adsorption on activated carbon prepared from gulmohar fruit shell was studied to determine the effects of dosages and pH accordingly to equilibrium and kinetics. The removal of fluoride by adsorption was studied on two types of carbons i.e., physically activated and chemically activated with I.R's of 0.25, 0.50 and 0.75.
