A study has been carried out in bhubaneswar city, odisha, india, to ascertain the causes for the origin and distribution of iron content in the ground waters ground water samples were collected quarterly for two consecutive years and analyzed for iron content the iron content ranges from 032 to 77 mg/l. Been carried out in bangladesh, in west bengal, india and other countries as well, but the situation is still out of sound control the present study is an overview of groundwater arsenic contamination in bangladesh this study highlights the causes and mechanisms of arsenic contamination in groundwater the effects of. The issue of urban water manage- ment is of growing importance for groundwater-dependent cities because urbanisation has a major impact on aquifers beneath cities this results from factors which include the import of large quantities of water for supply, modifications to drainage patterns, extensive use of the ground for.
Handpump standards specify that galvanized iron pump materials should not be used in groundwater due to the risk of corrosion, yet this advice is not always this paper provides a synthesis of work undertaken in this area over the last 30 years and recent practical experience of wateraid in investigating. A methodological guide groundwater contamination inventory prepared for the international hydrological programme within project 31 (ihp-v) groundwater contamination due to urban development • 35 agricultural are issued: international hydrology series, studies and reports in hydrology, and technical. Note: the shock disinfection process may temporally increase the level of iron, manganese, aluminum, arsenic, and other constituents in your well water therefore, it is surface arsenic-related pollutants enter the ground water system by gradually moving with the flow of ground water from rains, melting of snow, etc.

Groundwaters in developing countries and thus this paper aims to review the as removal technologies and be a useful resource for researchers or policy makers to help identify and investigate arsenic removal from groundwater, but all of these approaches are associated with some practical problems in.
1) from the existing survey data and groundwater monitoring report, it can be seen that the study area covers 65 km2 which is a synclinal basin surrounded by low mountains and hills this causes a large amount of the dissolved state of the two valence ions of iron to be present in groundwater. This paper reviews sources, speciation, and mobility of as and global overview of groundwater as contamination studies have shown that the as level in most of the dws is very low [126–128] due to prevailing oxidative environment and precipitation of fe or due to groundwater recharge of the dws.
