      [1] To investigate arsenic mobility in the Bengal Basin groundwater, we sampled water wells and sediments throughout the region. There are strong correlations among high levels of dissolved arsenic and iron, ammonia, and methane, especially in samples from a single site (Laxmipur).Cited by: West Bengal is well endowed with groundwater. Net annual groundwater availability is high ( billion cubic meters) as is rainfall ( mm per year), yet its potential for development in many regions has not been reached. Only around 42% of the state’s groundwater resources are being used.

Shamsudduha, Ashraf Uddin So, a change in climate and shifts in sedimentary environments in response to changing sea level from Pleistocene to Holocene exerted a strong control on As distribution in the alluvial plains of Bangladesh and W.

Information is required to sustainably manage groundwater resources in this district. METHODS Geology of the study area The study was conducted in an area of the Bengal (latitude 21basin °45′N to 22°30′N, longitude 88°15′E to 88°30′E) situated in the southern part.

West Bengal has 37 semi-critical and 1 critical blocks based on the study of CGWB during (Ray and Shekhar, ). While all the 38 blocks has been categorized as semi-critical as on March, (Central Ground Water Board, ).

Table 1.b represents the semi-critical and critical blocks of West Bengal during Area under Study. The principal issues associated with water in West Bengal include river degeneration, channel shifting, flood, urban waterlogging, drought, pollution, groundwater depletion and inland navigation.

Ground Water Condition at Some Indian Mines Very often, in India, a mine planner or a mining engineer faces ground water. Possible relationships between groundwater arsenic concentration and alluvial sediment characteristics in a ~19 km2 area in West Bengal have been investigated using a combination of.

Depending on soil and climate variations, West Bengal can be divided into six broad divisions: The hill region in the north; The terai and Teesta alluvial region of North Bengal; The laterectic, red and gravely undulating region in the west; The coastal alluvial region in the south; The gangetic alluvial region in the west.

West Bengal has a very good groundwater potential. The reason of such affluence is due to her geographical location, high rainfall, and geological setting. But in recent times groundwater development in some districts in this state has been increased to such an extent that in some areas conditions of near overexploitation has developed.

The yield of wells tapping fractured zones varies from m3/hr. Two third of the State is underlain by alluvial sediments mainly deposited by Ganga & Brahmaputra rivers. Based on the yield of wells tapping these alluvial sediments, aquifers of the alluvial area can be divided into three zones.

Abstract. Arsenic contamination in groundwater used for drinking purposes has been envisaged as a problem of global concern. Exploitation of groundwater contaminated with arsenic within the delta plains in West Bengal has caused adverse health effects among the population within a span of years.

The sources of arsenic in natural water are a function of the local geology, hydrology and geochemical characteristics of the by: State’s groundwater resources are being used because of policy restrictions and concerns over groundwater scarcity and quality. Groundwater has played an important role historically in West Bengal’s agricultural productivity.

In the late s and early s. Arsenic contamination in groundwater affecting West Bengal (India) and Bangladesh is a serious environmental problem.

Contamination is extensive in the low-lying areas of Bhagirathi–Ganga delta, located mainly to the east of the Bhagirathi by: The South Parganas district of West Bengal comprises vast thickness of alluvial sediments deposited under different environmental conditions overlying the Tertiary sedimentary formations.

In some areas of Bangladesh and West Bengal, concentrations of As in groundwater exceed guide concentrations, set internationally and nationally at 10 to 50 μg l −1 and may reach levels in the mg l −1 range.

The As derives from reductive dissolution of Fe oxyhydroxide and release of its sorbed by:   This resource contains various hydrogeological data from the SW Bengal Basin in India and Bangladesh. These data have been used in a cross border groundwater studies aiming to understand the sources of high arsenic concentration in deep (>m) groundwater.
