ARSENIC MITIGATION & SAFE WATER PROGRAM

DCH is the pioneer organization in the field of Arsenic contamination in Bangladesh. It really deserves the sole credit for highlight the serious health hazards caused by arsenic contamination in ground water. DCH has implemented deferent kinds of safe water options like River Sands Filter (RSF), Rain Water Harvesting, Dug-well, Water Quality Test etc. About 100000 people are getting arsenic free safe water in arsenic affected areas of Bangladesh. In addition DCH has implemented the following programme on Arsenic Mitigation and Safe Water

1. 500 Villages Rapid Assessment Project

Ministry of Health and Family Welfare & UNDP Financial Survey

DCH community Hospital has completed first house to house arsenic testing and family screening in 500 villages of 29 districts under the project of Ministry of Health and Family Welfare funded by UNDP. The objectives of the screening program was to test all the tube-wells in the selected villages, to identify safe and hazardous well and mark them red or green accordingly, and to identify arsenic patients. It was also required that village maps were prepared and locations of tube-wells reproduced on these maps. Tube-well and health related data were to be collected using pre-tested questionnaire. It was also expected that the results of the findings would be shared with villagers along with appropriate messages on how to address the arsenic problem. The program was divided into two phases.

Phase I: In the first phase of the program, 21 districts were selected from where reports of cases of arsenicosis were available from existing database. From these districts, 200 villages were selected based on reports of existence of contaminated tube-wells from any known source. The program involved 15 teams to carry out the field activities. Each team comprised of three groups: initial screening group, water-quality testing group and health group. The initial screening group and the water quality testing group each had five workers. The health group consisted of nine members. There was one coordinator for supervising the work.

Phase II: With the same criteria of selection, the second phase expended the program to a further 300 villages selected from eight new and earlier 21 districts, the criteria of selection remaining the same. The field staff was divided into four groups with each group having one medical officer, one mapper, one monitoring officer and one field coordinator. Each group was divided into four teams. Each team had two water testers, three health workers and one supervisor. The field staff also included one dermatologist and one field coordinator. There was one coordinator in charge of overall supervision.

2. Action Research on Community Based Arsenic Mitigation in Bera Upazila

   (Under 5 upazila UNICEF-DPHE)

Dhaka Community Hospital has implemented an integrated arsenic mitigation project in Bera Upazialla of Pabna District supported by DPHE-UNICEF. The testing and marking all tube wells, the arsenicosis identification and the long term management, rehabilitation and installation of alternative safe water options and water quality monitor, awareness building and community mobilization are the major activities of the project.

In Bera Upazilla DCH has tested all TWs using field test kits and has found that 51.5% of the hand tubewells were contaminated. 60 % tube wells have been sank during last 5 years and 53 % tube has got depth between 25 to 60 feet. DCH has installed and was continuing install alternative safe water options. The options include Pond Sand Filter, Rain Water Harvesting (cum Sand Filter), Dug wells, Pitcher filter (Kalshi and Chari)

Water quality tests, e.g. bacterial count and the arsenic concentration following introduction of these options have been carried outdone periodically with field test kits and with the laboratory. The test results have all been communicated to the tube well users. The water qualities of the alternative sources have been found in safe level for drinking and cooking. 

In the project, DCH has identified arsenicosis by screening all members of all families in Bera Upazilla. The initial identification of arsenicosis patients was done by skin manifestation and was then confirmed by testing patient’s urine, nail and blood samples. DCH identified 120 patients. Out of them children are 20 %. The Male is 50.8% and female is 49.2%

The patients were being treated by providing arsenic free safe water and vitamins, both of which are closely monitored. 21 serious arsenicosis patients from Bera have been treated in the DCH Hospital.

Regular village meetings are going on with the Bera communities to inform them about arsenic as a health hazard and sensitize them to alternative safe water options and personal hygiene education.

9 .Bangladesh- Australia Centre for Arsenic Mitigation project:

  Supported by AusAID, Australia

This was AusAID funded project Implemented by Dhaka Community Hospital, Associated with GHD, CSIRO, CRC and South Australia University (Australia). There were 4 components of the project, which were implemented in different parts of Bangladesh to mitigate the arsenic problem.

Program 1: Establish the Bangladesh Australia Centre for Arsenic Mitigation

To establish a Centre for Arsenic Mitigation in Bangladesh which was set up at Dhaka Community Hospital (DCH), and capable of providing professional ongoing advice on safe water and food, human health and well being to arsenic affected communities through Resource Centre.    

Program 2: Safe Clean Water

To determine the most appropriate treatment methods or alternative water supply options (surface water/rainwater) for providing safe drinking water and establish their application more widely.

Program 3: Safe Food

To establish a program which enabled the Government of Bangladesh to obtain a better understanding of the potential for exposure to arsenic via the food channel, the significance of this exposure, and the strategies that should be adopted at the village level to reduce the risk associated with this exposure.

Program 4: Community Health Education

To develop and implement Community Health Education System in conjunction with the local communities.

10. Analyzing the socio-economic conditions for the implementation and maintenance of Arsenic risk mitigation measures

Swiss Federal Institute of Aquatic Science and Technology (Eawag), Switzerland

Dhaka Community Hospital conducted a survey as a part of a multidisciplinary research project initiated by the Swiss Federal Institute of Aquatic Science and Technology (Eawag), Switzerland. The outcome of this survey was help to develop a framework for mitigation of geogenic contaminants.

The main objective of this household survey is to identify and analyze household level socio-economic conditions, drinking and other water usage patterns and their relationship with a household’s ability and willingness to pay for arsenic free drinking water. This survey was also identify the household level stockholder’s preferences for a particular mitigation option and any current constraints preventing the adoption of any arsenic mitigation options

During the Survey activities we found that many people were using arsenic contaminated tube-well water for drinking and cooking purpose. Majority of the population of the survey area were awarded about arsenic contamination in tube-well water. But they were drinking and cooking with arsenic contaminated water due to availability of safe water option, habituated with tube-well water use, lack motivation and training to change the habituate to use safe water options like rainwater harvest, dug-well, RSF and PSF etc. and limitation on arsenic removal filter and deep tube-well. Implementing areas: Sirajdikhan (6 Village), Munshigonj, Sujanagar (3 village), Pabna ,Ishwardi (1 Village) Pabna, Laksam (3 village), Comilla.

13. Wilson Arsenic Mitigation Prorame:

 Arsenic Foundation INC

DCH has implemented on arsenic mitigation programme with financial assistance from Prof. Richard Wilson, Department of Physics, Harvard University, USA. Under this programme total 66 dug well (renovated & installed) with pipeline network installed and 1418 families 7632 Population are getting arsenic free safe water. Almost 126 arsenicosis patients are gradually improving by drinking safe water. This program was working at three phases.

Phase-1  Renovated & Installed 39 DW (1 with pipe line system)and covered 631 families Serving 3250  users

Phase 2 Installed 17 DW (with pipe line system ) and covered 518 families Serving 2903 users

Phase 3  Renovated 9 DW & newly installation of 1DW(with pipe line system) and covered 269 families serving 1479 users        

The project successfully achieved its implementation targets of sixty-six dug wells and pipe networks in Harvard project area in Pabna district, on time. 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.

Wilson Arsenic Mitigation Program : River Sand Filter (RSF)

Under this programme we provide arsenic free safe water to the community of arsenic affected area. DCH has installed  6 River Sand Filters with pipe line system in Sirajdikhan upazila. The objectives of the programme are:

To share with policy makers, researchers, donors & investors who are engaged or interested in providing arsenic free drinking water, on our experience and learning from  the alternative water option, To spread all over the country by accepting as a model from the success of this program of the alternative water option.

10. Piped Water Supply System from River Sand Filter for Shushunda Village along with Health & Hygiene Education

Supported by Mercy-Malaysia

Dhaka Community Hospital (DCH) made a survey on Arsenic in 2001. About 99% tube-wells were found arsenic contaminated and about 150 arsenic patients were diagnose in Shushunda village After this DCH implemented some arsenic mitigation, patient management and awareness programme from its own fund and there were some government mitigation as well. But it was not sufficient and they had to manage by themselves. In February 2012 DCH did another survey and found majority of the tube-well are arsenic contaminated and huge number of patients are increased. Before implementation of RSF in Shushunda village there was no arsenic free safe water option. So DCH and Mercy Malaysia selected this village for installation of RSF.

Project Objectives:

To supply arsenic, chemical and bacteria free safe water to the community through piped water supply system of River Sand Filter at an affordable cost for drinking and cooking purposes in arsenic affected village.

To provide medication and skin ointment for 350 arsenicosis patient for a year to reduces symptoms of arsenicosis among the villagers.

Project Activities and Outputs

Activities Outputs Achieved
Selection of site & beneficiaries; area mapping of the pipeline network   Drawing & design of RSF unit A functioning RSF unit installed at Shushunda Village30 tap points installed to deliver water directly to household level. This reduces safety risk of young children and women who collect water up to 3 times and as much as 80 litres a dayAverage 5 families are included in one tap point. The RSF unit is currently supplying filtered water to 130 families (equivalent to 650 people) through the 30 tap pointsAnother 350 to 400 community members from nearby villages fetches water directly from the unit through the 3tap outlets availableHence in total, the RSF is currently serving the drinking water needs of more than 1000 people each day
Mobilisation of community members by formation of a Management Committee & training of a caretaker Formal hand-over of the RSF unit to the Management Committee A Management Committee, consisting of female and male community members and a caretaker were appointed amongst the community membersThis structure is established to inculcate sense of ownership and increase sustainability of the project200 Taka is collected from each tap point (where 5 families are involve in one tap point) each month for caretaker allowance, electricity charges and general maintenance of the unit
Water quality testing The 2 rounds of water testing conducted recorded results within the permissible levelTests conducted were pH, fecal coliform, total coliform, arsenic, turbidity, conductivity and Total Dissolved Solid (TDS)
Arsenic patient management Salicylic acid and multivitamins are distributed to 150 confirmed arsenic patients in Shushunda VillageThe distribution has been conducted since January 2013 and will be done until December 2013
Continuous monitoring and evaluation (M&E) M&E related documents prepared for the project as follows: – Background of DCH and MM – Management Committee members and their tasks – Selection criteria – Beneficiary list – Contact details of the relevant staff (both MM, DCH HQ and field staff) – Complaints Form and Suggestion Box These information is displayed at the village bazaar (market) and at the Shushunda RSF Unite

11. Arsenic Mitigition Project

Supported by MERCY Malaysia (MM)

Arsenic Mitigation Project:

MERCY Malaysia is working on an Arsenic Mitigation Project in the village of Kabarikhola, Bangladesh, which aims to provide publicly accessible safe and arsenic-free water. The project features a man-made well locally referred to as Indara, which is a community-based safe-water option. This involves renovating the well and supplying safe arsenic-free water to households through an extensive pipeline network. This project is a collaboration of MERCY Malaysia and the Dhaka Community Hospital.

12. Rain Water Harvesting (RWH) Programme

Supported by MERCY Malaysia (MM)

DCH has implemented the RWH programme to provide arsenic-free safe water to households of the underprivileged people of Ruppur, Kabarikhola, Ratangonj and Jadupur Pabna in collaboration with MERCY Malaysia. 180 RWH preservers have been installed in villages which include Ruppur, Kabarikhola, Ratangonj and Jadupur. About 400 families are benefitting from this programme. The overall cost of one RWH preserver is estimated at BDT Tk 30,000.00 which is about USD400. The preservers are given free of charge, however, users need to pay their own maintenance cost. There are very positive community attitude to seeking alternative water options. At the household level the community has accepted RWH as an alternative to the arsenic contaminated tube well. The community is supportive of the RWH project. The caretaker keeps records of incidences of diarrhoea amongst the beneficiaries of RWH. The RWH is very high in efficiency in the turbidity of arsenic affected communities.
