Arsenic contamination of groundwater in Bangladesh

  title={Arsenic contamination of groundwater in Bangladesh},
  author={David G. Kinniburgh and Pauline L. Smedley},
A survey of well waters (n=3534) from throughout Bang- ' ladesh, excluding the Chitt;agong Hill Tracts, has shown that water from 27% of the 'shallow' tubewells, that is wells less than 150 m deep, exceeded the Bangladesh standard for arsenic in drinking water (50 flg L -I). 46% exceeded the WHO guideline value of 10 flg L-I. Figures for 'deep' wells (greater than 150 m deep) were 1% and 5%, respectively. Since it is believed that there are a total of some 6-11 million tubewells in… 

Experiments on Alleviating Arsenic Accumulation in Rice Through Irrigation Management

Arsenic (As) in groundwater is a major health concern in Bangladesh and the risks of As ingestion using shallow tubewells (STWs) for drinking-water was identified in the deltaic region, particularly

Geostatistical analysis of arsenic concentration in groundwater in Bangladesh using disjunctive kriging

The National Hydrochemical Survey of Bangladesh sampled the water from 3,534 tube wells for arsenic throughout most of Bangladesh. It showed that 27% of the shallow tube wells (less than 150 m deep)

Arsenic contamination of groundwater and drinking water in Vietnam: a human health threat.

The high arsenic concentrations found in the tubewells indicate that several million people consuming untreated groundwater might be at a considerable risk of chronic arsenic poisoning.

The Middle Ganga Plain (MGP) is the second largest arsenic (As) contaminated groundwater zone in south-east Asia after the Bengal Delta Plain. About 90% of the total population in the MGP depends on

Electrochemical arsenic remediation for rural Bangladesh

Arsenic in drinking water is a major public health problem threatening the lives of over 140 million people worldwide. In Bangladesh alone, up to 57 million people drink arsenic-laden water from

Arsenic mitigation: water quality of dug wells and tubewells

Arsenic concentration in very shallow and deep aquifers is comparatively lower than shallow aquifers in arsenic contaminated areas. As a result, dug wells and deep tubewells have emerged as two major

Monitoring 51 community wells in Araihazar, Bangladesh, for up to 5 years: Implications for arsenic mitigation

Monitoring data spanning a period of up to 5 years for 51 community wells, 115–545 ft (34–164 m) deep, installed in Araihazar upazila, Bangladesh shows that all but 4 of these community wells have consistently provided drinking water that meets the Bangladesh standard for As in drinking water; the increase in As concentrations in 4 community wells indicates that all deeper tubewells should be periodically re-tested.

Security of deep groundwater against arsenic contamination in the Bengal Aquifer System: a numerical modeling study in southeast Bangladesh

Across the floodplains of southern Bangladesh deep (> 150 m belowground level, bgl) groundwater within the Bengal Aquifer System (BAS) has become widely used for domestic water supply as a de facto
