Abstract:
Human activities are considered to be contamination. Every persons wants clean water for drinking, bathing and other domestic uses, but not everybody appreciates the fact that our own actions are often the worst enemy in achieving that goal. Ground water is one of the most misused and misunderstood resources. Because ground water and its movement, and consequently also its pollution, is hidden from view beneath the land surface, the seriousness of ground water pollution problems has not been recognized until recently. The sources of manpur block ground water pollution are many and varied becau

Abstract. Bacteriophages are increasingly used as tracers for quantitative analysis in both hydrology and hydrogeology. The biological particles are neither toxic nor pathogenic for other living organisms as they penetrate only a specific bacterial host.

Several years of research make them suitable for quantitative transport analysis and flow boundary delineation in both surface and ground waters, including karst, fractured and porous media aquifers.

Fields have uneven surfaces, such as ridges, and the shortwave radiation of fields differs depending on the orientation of the slope of the unevenness, resulting in variations in the distribution of moisture on the ground surface.

Previously, one-dimensional simulations have been used to estimate the heat and water balance of non-sloping surfaces.

Abstract:
One of the major problem for fishermen of Tolo Bay water in optimizing the utilization of the fish resources is the difficulty in determining potential fishing grounds. The fishing area is very much determined by the distribution of oceanographic parameters, in particular the distribution of sea surface temperature and chlorophyll-a concentration. The aim of the reaserch is to estimate the fishing ground using integrated sea surface temperature and chlorophyll-a distribution image data from Aqua-Modis Level 3 Satellite and Seades 7.2. The Reseacrh was conducted using GIS-based Remote Sensing M

Abstract:
The role of surface water is also the main reason for the formation and development of ground fissures. Five mechanisms were obtained on the formation of ground fissures under the role of surface water in the loess region through theoretical analysis, i.e., fissuring mechanism induced by loess collapsible deformation; that induced by dissolution and suffosion; that induced by water-loss shrinkage; that induced by hydraulic pressure; that induced by humidification and softening. As the role of surface water had certain phased and periodic characteristics, repeated fissuring mechanism of ground

Pollution of water sources have become a common problem these days, be it ground water source or surface water sources. The most important and major usage of ground water is for irrigation unfortunately groundwater is susceptible to pollutants that may enter into the subsurface ground water by runoff. Presence of microbes in drinking water is now common problems as majority of the ground water sources are being substantially polluted. the physico chemical and microbial properties of water was studied and was found that the treated water sample showed a better water quality rating than the raw

Abstract:
Pollution in water occurs when harmful substance (often chemicals or biological) contaminate streams, river, lakes, oceans or other bodies of water, degrading water quality and rendering it unhealthy to humans, animal and the environment. The widespread problem of water pollution is jeopardizing our health. Water pathogens, in form of disease-causing bacteria and viruses from human and animal waste, are a major reason of illness from contaminated drinking water. Owing to the improper treatment facilities, waste is often discharged into the surface and ground water sources. Water bacteria can b

AbstractIn many areas of south and south-eastern Asia, concentrations of As in ground water have been found to exceed the WHO maximum concentration limit of 10 μg/l. This is adversely affecting the health of millions of people and has grave current and future health implications. It has recently been suggested that extensive abstraction of ground water in these areas may accelerate the release of As to ground water. This study uses geochemical and isotopic data to assess this hypothesis. The area investigated in this study is in the Chakdaha block of the Nadia District, West Bengal. The ground
