Resumen

The scale of arsenic toxicity of the groundwater in Bangladesh is greater than any environmental debacle in the history of human civilization. The main route of arsenic accumulation in the human body is the ingestion of arsenic tainted water. Because of the undetectable nature of arsenic poisoning at the early stage and lack of awareness due to mass illiteracy, poverty and malnutrition, arsenic related ailments may cause death. However, this paper mainly discusses arsenic mitigation measures in Bangladesh. Although a piped surface water supply after treatment is the absolute solution to get rid of this crisis, the weak economic background of Bangladesh does not support supplying such water to every corner of rural areas. Hence research groups have developed their own methods to suit the local environment, using locally available materials and approaches based on the common method of arsenic removal: use of oxidizing agents, followed by flocculation and precipitation. Again, among different alternative water supply options, deep tubewells, which have been used by the communities in Bangladesh during the past few decades, appear to be a more suitable alternate option. Moreover, household-based arsenic filters can be a good choice if proper maintenance can be done.

Resumen

In March 1997, we analyzed the water of all tubewells used for drinking in Samta village in the Jessore district, Bangladesh. It has been confirmed from the survey that the arsenic contamination in Samta was one of the worst in the Ganges basin including West Bengal, India. 90% of the tubewells had arsenic concentrations above the Bangladesh standard of 0.05 mg/l. Tubewells with higher arsenic concentrations of over 0.50 mg/l were distributed in the southern area with a belt-like shape from east to west, and the distribution of arsenic concentration showed gradual decreasing toward northern area of the village. In order to examine the characteristics of the arsenic distribution in Samta, we have performed investigations such as: 1) the characteristics of groundwater flow, 2) the distribution of arsenic in the ground, 3) the concentration of arsenic and the other dissolved materials in groundwater, and 4) the distribution of arsenic concentration of trivalence and pentavalence. This paper examines the mechanism of arsenic release to groundwater and explains the above-mentioned characteristics of the arsenic contamination in Samta through the investigations of the survey results for these years.

Resumen

The purpose of this paper is to provide an overview of the problems concerning the widespread occurrences of arsenic in groundwater in Bangladesh, a land with enormous resources of precipitation, surface water, and groundwater. Because of the potential risk of microbiological contamination in the surface water, groundwater was relied on as an alternate source of drinking water. Exploitation of groundwater has increased dramatically in Bangladesh since the 1960s to provide safe water for drinking and to sustain wetland agriculture. The presence of arsenic in the groundwater at elevated concentrations has raised a serious threat to public health in the region. Nearly 6075 million people inhabiting a large geographical area are at potential risk of arsenic exposure, and several thousands have already been affected by chronic arsenicosis. The source of arsenic in groundwater is geogenic and restricted within the Holocene sedimentary aquifers. Mobilization of arsenic from the alluvial aquifers is primarily effected through a mechanism of reductive dissolution of the iron oxyhydroxides within the sediments, rather than by the oxidation of pyrite, as has been hypothesized by other workers. The problem is further accentuated by the fact that arsenic is also found at elevated concentrations in vegetables and rice grown in the areas where high-arsenic groundwater is used for irrigation. Dietary habits among the population are also an important pathway for arsenic ingestion. Studies are in progress at national as well as international levels to alleviate the arsenic crisis in Bangladesh. Besides the identification of arsenic-free tubewells in the affected areas for drinking purposes, purification of groundwater at household level by low-cost arsenic removal techniques is suggested. Rehabilitation of the patients with chronic arsenicosis and arsenic education programs for rural communities must be addressed urgently by the government of Bangladesh. Key words: arsenic, groundwater, chemistry, redox, causes, effects, Bangladesh.

Resumen

The groundwater pollution by arsenic in Bangladesh causes a serious problem for millions of people who are exposed to poisoning by this toxic element. In an attempt to evaluate the extent of arsenic poisoning, hair samples of people living in Pabna district were collected. The hair samples were analyzed using Proton Induced X-ray Emission (PIXE) through exciting the atoms of a specimen so that their intensities can be converted into elemental concentrations in the specimen. The elements present in the specimen are identified by the corresponding X-ray energies and their concentrations are deduced from the X-ray intensities. The results from hair samples indicate substantially higher level of arsenic than those demarcated as toxic levels, in people from member families both affected and non-affected by poisoning. We correlate it with exceedingly high arsenic concentration in drinking water far above the permissible limit. The analytical results are compared with the results of arsenic and other elemental analysis of 160 Bangladeshi hair samples with that of 250 Japanese samples. The results show markedly higher levels of arsenic, manganese, iron and lead where the latter three elements show a positive relation with arsenic in the case of Bangladeshi as compared to the samples from Japan. On the other hand, selenium concentrations show very low level in the Bangladeshi samples compared to Japanese, displaying an inverse relationship with arsenic. The mechanism of arsenic in relation to other elements in the human body needs further investigation. The preliminary results call for detailed experimental and epidemiological studies to further characterize these aspects.

Resumen

Serious arsenic contamination of groundwater in Bangladesh has been frequently reported and is of great concern. In this research, repeated water sampling from the same 10 tubewells in Nawabganj municipality, Bangladesh, was conducted and analysed, focusing on the seasonal variation of water quality and the relationship among arsenic and other metals and ions. For the seasonal variation of water quality, arsenic and iron concentrations were higher in the rainy season in general although the tendency was not consistent and it depended on the tubewell and the time. Correlation between arsenic and iron could not be observed in this study (r = −0.01) when using all cases. This was because no correlation was observed in the higher arsenic concentration range. Arsenic removal by co-precipitation with coexisting iron is known as one of the locally applicable techniques in Bangladesh, but the result from this study suggests that some additional treatments such as the extra injection of iron should be performed in some cases, especially where the arsenic concentration is high. The correlation between arsenic and other substances was also analysed. As a result, manganese (r = 0.37), molybdenum (r = 0.33) and sulfate ion (r = −0.33) significantly correlated with arsenic (p<0.05). The negative correlation between arsenic and sulfate ion implies the dissolution of arsenic into groundwater under reductive conditions although there are some exceptional cases.

Resumen

In the context of arsenic contamination of groundwater in Bangladesh, this paper analyses rural people's preferences for arsenic-free drinking water options. A particular focus is on rural households' willingness to pay for piped water supply which can provide a sustainable solution to the arsenic problem, and how the preference for piped water supply compares with that for various other household/community-based arsenic mitigation technologies. The analysis is based on data collected in a survey of over 2700 households in rural Bangladesh. Six arsenic mitigation technologies were selected for the study: three-kolshi (pitcher) method, activated alumina method (household-based and community-based), dugwell, pond sand filter and deep tubewell (handpump). The survey results indicate that, after taking into consideration the initial and recurring costs, convenience, associated risks and the advantages and disadvantages of each selected technology, the preference of the rural people is overwhelmingly in favor of deep tubewells, followed by the three-kolshi method. The analysis reveals a strong demand for piped water in both arsenic-affected and arsenic-free rural areas, and scope of adequate cost recovery. Between piped water and other arsenic mitigation technologies, the preference of the rural people is found to be predominantly in favor of the former.

Resumen

The soil samples and tubewell waters were collected from 25 locations representing five thanas of four districts of Bangladesh. The soils were collected from three depths viz. 0–15, 15–30 and 30–45 cm and tubewell waters were collected from same locations. The arsenic content of soils and waters were detected by Molybdenum blue method. The arsenic content in soils ranged from 1.27–56.68, 3.18–54.77, 1.27–50.95, 1.27–39.48 and 3.18–35.66 ppm in Chapainawabganj Sadar, Kustia Sadar, Bera, Ishurdi and Sarishabari thanas, respectively. Out of a total of 25 samples arsenic was detectable for 18 samples at 0–15 cm, 17 samples at 15–30 cm and 15 samples at 30–45 cm depth. One sample at 0–15 cm, 7 samples at 15–30 cm and 4 samples at 30–45 cm depth were found to be slightly contaminated. In tubewell water the arsenic content measured from Chapainawabganj Sadar, Kustia Sadar, Bera, Ishurdi and Sarishabari thanas were ranged 0.010–0.056, 0.010–0.071, 0.010–0.056, 0.010–0.056 and 0.025–0.071 ppm, respectively. Out of 25 water samples 17 contained variable amounts of arsenic where 6 sampling sites contained arsenic levels above 0.05 ppm, and these sites are Rajarampur of Chapainawabganj Sadar thana, Jordaha of Bera thana, Courtpara of Kustia Sadar thana, Nalgari of Ishurdi thana and Ijarapara of Sarisabari thana. Arsenic contained in soils was positively correlated with arsenic content in waters.

Resumen

Rooftop rainwater harvesting has received an increased attention as a potential alternative water supply source both in the coastal and arsenic affected rural areas in Bangladesh. Several programs in installing rainwater harvesting systems have been implemented to mitigate the drinking water problem in the coastal and arsenic affected areas in the country. This study was conducted with a view to assess sanitary integrity, microbial contamination and the associated health risk of the currently practiced rooftop rainwater harvesting mainly used for drinking water supply. Sanitary inspection of the rainwater harvesting systems and an extensive sampling of harvested rainwater from the storage reservoirs and laboratory analysis were conducted. The study findings reveal that harvested rainwater was found to microbiologically contaminated to some extend. The disease burden estimated using QHRA model showed a significant microbial health burden associated with drinking untreated rainwater and both viral and bacterial pathogens dominate the microbial disease burden. In context of arsenic mitigation, rainwater harvesting reduces the health risk from arsenic; however it may increase the microbial disease burden much higher than the level of arsenic health risk at 50 μg/L of Bangladesh standard. Microbial risk needs proper attention through the implementation of a water safety plan for safe and sustainable rainwater harvesting in Bangladesh.

Resumen

Risk related to the ingestion of any water contaminants depends on many factors, including the daily per capita amount of consumed water relative to body weight. This study explored the water consumption pattern of a rural arsenic-affected population in Bangladesh. The study findings are likely to contribute to the risk estimation attributable to ingestion of arsenic and other drinking water contaminants. A total of 640 individuals participated in this cross-sectional study carried out in an arsenic-affected rural population in Bangladesh. In this study daily per capita water consumption for drinking purposes was found to be 73.04 ml/kg/d (range = 71.24–74.84 ml/kg/d), which is higher than for both the US and Taiwan populations. This difference in per capita drinking water consumption might contribute to much higher lifetime cancer mortality and other morbidity risks from arsenic among the Bangladesh population compared to either the US or Taiwan populations. Arsenic is also ingested through cooking water which, if considered, might increase the risk further. The findings of this study highlight the urgent need for a holistic water supply programme for Bangladesh, with special emphasis on the arsenic-affected population.

Resumen

As a result of naturally occurring arsenic in groundwater, it is estimated that 42–60 million people in Bangladesh are exposed to arsenic at concentrations greater than the World Health Organization (WHO) guideline of 10 μg/L. Arsenic-Iron Removal Plants (AIRPs) are capable of removing 50–90% of arsenic from groundwater, but are frequently unable to meet the WHO guideline. The effectiveness of three design modifications intended to improve the performance of AIRPs is described: (1) the addition of scrap or locally available iron to the filtration media, (2) raising the intake pipe that connects the two tanks of the AIRP, and (3) introducing baffles to the aeration tank. Total arsenic, iron, phosphate, and dissolved oxygen were measured to determine the impact of each modification. The addition of iron media showed an increase in arsenic removal up to 13%, while raising the pipe intake accounted for a 3% increase in arsenic removal. The installation of both modifications to the same AIRP is expected to reduce the lifetime body burden from drinking water by one-half. The addition of baffles to the aeration tank showed no evidence of improving the arsenic removal capabilities of the AIRP.

Resumen

UNESCO-IHE has been developing an arsenic removal family filter with a capacity of 100 L/day based on arsenic adsorption onto iron oxide coated sand, a by-product of iron removal plants. The longer term and field conditions performance of the third generation of eleven family filters prototypes were tested in rural Bangladesh for 30 months. All filters achieved initially highly effective arsenic removal irrespective of arsenic concentration and groundwater composition. Arsenic level in filtrate reached 10 μg/l after 50 days of operation at one testing site and after 18 months of continuous operation at other 3 testing sites. Arsenic level at other 7 sites remained below the WHO guideline value till the end of study. Positive correlation was found between arsenic removal capacity of the filter and iron concentration in groundwater. In addition to arsenic, iron present in groundwater at all testing sites was also removed highly effectively. Manganese removal with IHE family filter was effective only when treating groundwater with low ammonia. A simple polishing sand filter, after IHE family filter, resulted in consistent and effective removal of manganese. IHE family filters were easy to operate and were well accepted by the local population.
