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… 
Status of groundwater arsenic contamination in Bangladesh: a 14-year study report.
Water analyses from the four principal geomorphological regions of Bangladesh showed that hand tubewells of the Tableland and Hill tract regions are primarily free from As contamination, while the Flood plain and Deltaic region, including the Coastal region, are highly As-contaminated.
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
Spatial variability of arsenic in 6000 tube wells in a 25 km2 area of Bangladesh
[1] Arsenic concentrations measured by graphite furnace atomic absorption range from < 5 to 900 μg/L in groundwater pumped from 6000 wells within a 25 km2 area of Bangladesh. The proportion of wells
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.
Groundwater Arsenic Contamination and Availability of Safe Water for Drinking in Middle Ganga Plain in India
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
Arsenic groundwater contamination and its health effects in the state of Uttar Pradesh (UP) in upper and middle Ganga plain, India: a severe danger.
The similarity to previous studies on arsenic contamination in West Bengal, Bihar and Bangladesh indicates that people from a significant part of the surveyed areas in UP are suffering and this will spread unless drives to raise awareness of arsenic toxicity are undertaken and an arsenic safe water supply is immediately introduced.
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

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

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.
