1. Introduction

 

 1.1  Arsenic Problem – Situation of Bangladesh

 

Arsenic contamination in groundwater and its toxic effect on human health is a major public health problem in Bangladesh. In Bangladesh around 97% of the people are dependent on water supply from the groundwater source at present. For more than 30 years tube wells have been introduced for safe drinking water and domestic purposes on a mass scale. But recently the arsenic contamination in groundwater has made this source unsafe. This has created major problems, especially among the rural people. So far 61 districts out of 64 districts are affected with arsenic contamination in groundwater. It is estimated that about 85 million people in Bangladesh are at risk of arsenic toxicity. 

 

All the tube wells in Bangladesh have not yet surveyed. Only about 10-15% tube wells have been surveyed and found that 70% and 40% tube wells have arsenic level above the World Health Organization (WHO) and Bangladesh water quality standard of 0.01 and 0.05 mg/l respectively (DCH, 1998; DPHE, 1997). In some villages 100% of tube wells are contaminated with high level of arsenic.

 

 

1.2  Hazards of Arsenic Intake

 

Severe health effects have been observed in populations drinking arsenic-rich water over long periods in countries worldwide. The symptoms and signs that arsenic causes appear to differ between individuals, population groups and geographic areas. Arsenicosis ‑ the clinical syndrome originating from high dose arsenic poisoning ranges from spotted melanosis (skin pigmentation) and keratosis (thickening of skin of palm/ foot) up to carcinoma.    In Bangladesh keratoses of the foot often lead to gangrene which, if untreated, can lead to death.

 

Long-term exposure to arsenic through drinking water causes cancer of the skin, lungs, urinary bladder, and kidney, as well as other skin changes such as pigmentation changes and thickening (hyperkeratosis) gangrene of limbs.

 

Arsenicosis patients suffer also socially and culturally. Youths are refused marriage, many women and some men have been divorced and children are often asked to leave school. It is also important to non that no proper case management a arsenicosis case for prevalence was been under taken by government, or non government agencies. DCH also with is limited resources trying to case for the arsenicosis patients.     

 

 

1.3  Arsenic Mitigation Programme of DCH

 

DCH has been involved with the arsenic problem since 1996 when DCH doctors working at an annual health camp at Pakshi, Pabna District first detected patients suffering symptoms of arsenicosis.  DCH lobbied extensively to establish this issue as a public health problem and went on to work with Jadevpur University, Kolkata to sample survey the whole of Bangladesh.  Since then it has collaborated with various partners in research into the problem and solutions for mitigation as well as conducting its own arsenic projects.  DCH also provides training on arsenicosis and arsenic problems through its Institute of Family Health, including training for oversees medical personnel e.g. The Nepalese Health Department.

 

1.4  Wilson Arsenic Mitigation Program

 

For the last few years DCH has been implementing on arsenic mitigation programme with financial assistance obtained by Prof. Richard Wilson, Department of Physics, Harvard University, USA.  In the first phase of the mitigation programme, DCH renovated and installed 43 dug wells (including one with pipeline supply system). This phase covered 631 families – serving 3250 users. In the second phase, 17 dug wells with pipeline network were installed which covered 518 families – serving 2903 users.

 

In this process approximately 100 arsenicosis patients are getting arsenic free safe water. These patients are getting regular checkup by experienced doctors and it appears that they are improving.

 

2. Brief Description of Dug Well

 

Dug well is thousand years old technology of water supply in rural Bangladesh. Almost all the people used this technology before tube well came in. For the past 30 to 40 years hand tube well was promoted on a mass scale and as tube well became very popular source of drinking water and household purpose, dug wells gradually decayed because of non-use. Recently tube wells are found to be contaminated with high level of arsenic all over the country. To mitigate arsenic problem, Dhaka Community Hospital has started to provide dug well and other alternative safe water options (PSF, RWH etc) in the arsenic affected communities in collaboration with GoB and donor agencies. DCH is also providing dug wells with pipeline system in some areas.

2.2 Installation of Dug Well with Pipeline

 

As DCH has taken up the programme of dug well, a protocol for safety of dug well construction and keeping dug well water free from contamination was formulated. Later on this protocol was further strengthen by WHO protocol, which is now being followed (Annexure 3).   March and April, driest months in the country, are considered the best time for digging wells.  During this period, ground water remains at the lowest level.

 

A hole is dug about a diameter of 36 inches. The depth of each well varies from place to place. Cement or baked clay ring is set from bottom to top and joining of rings is cemented to keep the well water safe from contamination. An apron of about four feet is made around the head wall and a 30-40 feet drain is constructed at the ground level to avoid water logging around the head wall.

 

An electric pump machine pumps water from dug well to an overhead reservoir of 3000 L. Overhead tank is installed on an 15 feet tall iron stand. The stand is fixed on the ground with RCC work. A main water supply pipe (3 /4 '' plastic pipe) is connected with the tank for distribution of water to the household level. 1/2'' GI pipeline is connected with the mainline to supply water at the household. 40-50 households are connected with the supply line.

 

 

2.3 Cost of Digging Dug Well with pipeline

 

Digging a well with pipeline and cementing its floor at the ground level would cost an amount of Tk 85,000/= to 90,000/= The price however, may differ from place to place.

 2.4 Maintenance Procedure


                                        

Hardly any expense is required for maintaining                                                          

dug well. Well have to be cleaned once in a

year and it may cost an amount of Tk 3000 to

4000. The best time for cleaning is the period

between March and April.

 

2Kg lime is thoroughly mixed with 35 L of

water and then it is poured in the well. The well

water is stirred and then kept unused for 3 to 4

days. After 3 days the well is unloaded. The

well is then filled with fresh water seeping from

the aquifer.

 3. Project Implementation

 

Major activities of this project were as following:

 

1.     Community mobilization

2.     Committee formation

3.     Training of community worker and caretaker

4.     Site selection

5.     Drawing of water supply network

6.     Installation of dug well and pipe network

7.     Community meeting

8.     Water quality monitoring



3.1 Community mobilization                                       
                             


Various mobilization and motivational

activities such as courtyard meeting etc were

conducted to increase public awareness.

Several meetings were held in these villages

with the community. Local Government of

Bangladesh (GoB) elected persons

and influential local people were present in

meetings along with DCH personnel.

Community people including women, the

poor and arsenic patients shared their

situation, needs, opinions and preferences

about mitigation options with others.                                                             

                                                                                         Community Mobilization
                                                                                                                                   Figure 3: Community mobilization

 

 

3.2 Committee formation                                                                         

A committee was formed for the supervision

of each implementation. Each committee was

responsible to maintain the option provided

to them. DCH and the committees worked

together to plan option installation and

maintenance. Committee accepted responsibility

to collect community contribution.

                                                                                  

Committee decided the charges for water use

for each family. Caretaker collected money from

water users. Each family was provided with a                       

 water card for payment.                                                                             

                                                                                         committee formation

                                                                                                                                    Figure 4: Committee formation

.

 

 3.3 Training of community worker and caretaker

 

Local mistiris were selected for construction and maintenance of the options. They were

trained on construction work options by DCH trainers. DCH trainers also trained caretakers

and users of options.

 

 3.4 Site selection

 

Sites of option were selected in highly contaminated areas. This was done after consultation with the community. Preference was given to the patient families and the poor. Sites satisfied guidelines provided for site selection.

 

3.5 Drawing of water supply network   

 

Drawing of pipeline network and dug well was prepared. The pipeline network ended at the household level.

 

 3.6 Installation of dug well and pipe network                        

 

Process of the installation was discussed and

shared with the community. The committee

supervised during installation period.

This committee is responsible for maintenance.

 

Dug well sites were selected in environmental

friendly areas and in arsenic affected population.

Wells were protected from outside contamination.

Dug well water is stored in an overhead tank.

Water is supplied 2 or 3 times through pipeline         

at the household level. Villagers paid monthly            

fee for maintenance of the system.       

                                                                                          Installation

3.7 Community meeting                                              

Meetings with the community were held in
the project areas with the community.  Local

GoB elected persons and influential local

people were present in meetings along with

DCH personnel. Community people

including women, the poor and arsenic

patients exchanged opinions and identified

their needs.

                                                                                                          Figure 6: Community meeting   

 

 

3.8 Monitoring

 

Project activities were monitored by DCH through observations, open interview etc. DCH engineer monitored implementation activities. Clinical survey of water users was carried out per month.

 

The arsenic level of the dug well water was tested once in DCH after option installation. Bacterial count of dug well water was done at three monthly interval using either the DELAGUA or the  Jaltara field test kit.

 

4. Proposed 3rd Phase of Mitigation Programme

 

Drinking water supply from dug well through pipeline network is well received by the communities. This option should be replicated in other arsenic contaminated places. A plan for installing 100 new dug wells with pipe network in contaminated areas is proposed here in Table – 4.

5.     DISCUSSION

             

·        The project successfully achieved its implementation targets of seventeen dug wells and pipe networks in Harvard project area in Pabna district, on time and within budget.

·        There was a very positive community attitude to seeking alternative water options. The community supported the project and project personnel throughout the implementation period.

·        Each committee decided on a contribution of 20 Tk. per household per month from the community and the caretakers are collecting this. The money is used for maintenance and electricity charges for the pump.

·        Each committee has taken responsibility for maintaining the option.

·        The water column in dug wells at the driest period was 6 to 8 feet. This amount is sufficient to serve the communities.

 

 

 

6.     RECOMMENDATIONS

 

·       A dug well with pipeline network to the household level is readily acceptable by the community as an alternative to tube wells. A similar implementation programme can be extended to other arsenic contaminated areas. A 3rd phase of this programme is proposed (Page - 9).

·       Community involvement significantly enhances project sustainability through promoting the concept of community ownership of options.  This encourages a positive attitude towards community contribution for the option.

·       Economic contribution should be equitable. Community involvement also guarantees equitable community contribution.

·       Water option should be provided free of cost for the hardcore poor.

·       Some flexibility in project timing is required to take into account any political/institutional instability and the consequent delays this causes.

·       If possible these projects should be timetabled so that dug well installation commences in the dry season thus assisting implementation.

·       Patient management is also an important as part in mitigation activity needs to be address properly.
