26. Genesis Of High Arsenic Groundwater In The Bengal Delta Plains, West-Bengal And
Mattias von Br¶mssen writes on the soil chemistry that causes the problem.
Genesis of high arsenic groundwater in the Bengal Delta Plains, West-Bengal and Bangladesh
Division of Land and Water Resources, Thesis Report Series 1999:18
Department of Civil and Environmental Engineering
Royal Institute of Technology, Stockholm, Sweden
The high arsenic groundwater of the Bengal Delta Plain (BDP) in India as well as in Bangladesh, has become a priority health issue. A large population (
Arsenopyrite (FeAsS) and/or pyrite (FeS ) are the primary source of arsenic in natural systems. In sedimentary systems, arsenic is also adsorbed onto the reactive surfaces of secondary oxides and hydroxides of iron, aluminium and manganese (HFO, HAO and HMO). An aerobic (1) and an anaerobic (2) hypothesis have been put forward to explain the mobilisation of the arsenic in the groundwater. 1) When groundwater is withdrawn, oxygen may enter the aquifer and oxidise the primary sulphides and subsequently releases arsenic and sulphate in groundwater. 2) Alternately, arsenic may be derived as a result of desorption and reductive dissolution of the surface reactive mineral phases such as hydrous ferric, aluminium and manganese oxides (HFO, HAO and HMO) present as coatings in the aquifer sediments. Phosphate is adsorbed onto HFO in a similar way as arsenic. The mechanism of arsenic and phosphate is initialised by anoxic water in the aquifers.
Watersamples from wells in Chakdaha, West-Bengal, India and Bangladesh were analysed for a number of chemical parameters. Some porewater/BAT-point samples were also taken from a depth of 3 to 5 meters in Chakdaha and compared with the well samples. The groundwater was found to be neutral to slightly alkaline and essentially Ca-HCO

34. Welcome To Groundfreezing - Layne Christensen - Geotechnical Constructions Group
Ground freezing is a technique that has been used extensively for groundwater control and excavation support in the underground construction and mining industries for over 100 years.
Ground freezing is a technique that has been used extensively for groundwater control and excavation support in the underground construction industry for over 100 years.
The process involves the circulation of a refrigerated coolant through a series of subsurface pipes to convert soil water to ice, creating a strong watertight material. The material is so strong, in fact, that it is routinely used as the only method of groundwater control and soil support for the construction of shafts hundreds of feet into water-bearing soils.
Most ground freezing systems are quite similar in principal. The single most important component of a ground freezing system is the subsurface refrigeration system, consisting of a series of refrigeration pipes installed with various drilling techniques. Depending upon the application, the coolant can be brought to temperatures well below -150 degrees celcius. Ground freezing can be achieved by using either a large portable refrigeration plant or liquid nitrogen. After the initial freezing has been completed and the frozen barrier is in place, the required refrigeration capacity is significantly reduced to maintain the frozen barrier.

Groundwater Management What is Groundwater? Groundwater Protection Committees
2001 Annual Report
Groundwater is rain water that has filtered into (or recharged ) the ground and then stays beneath the surface like water in a wet sponge. All soil materials fill with water, although we usually think of groundwater being located in coarser soil materials such as sand or gravel, zones called aquifers where the water can easily be obtained and used. Finer soils, like silts, clays, and intact rocks, ( confining beds ) yield water only very slowly. Groundwater can be observed when it fills a well to a level called the water table . It moves from areas with a high water table to areas with a low water table, but at a very slow rate, usually only inches per day even in the most productive aquifers. Over a long time, groundwater discharges to surface water bodies such as lakes, wetlands, streams, rivers, and the ocean. Groundwater provides "base flow" for rivers - that's why they keep running after the rain has stopped falling. Groundwater is the major source of drinking water for citizens in the eastern, southern, and western (Vashon and Maury Islands) parts of King County, beyond the area supplied by the
