Saat ini IAGI sudah mempunyai 3 volunteer (fresh graduate) tetap di Aceh; dalam hal ini kita membutuhkan kawan-kawan yg lebih senior untuk berpartisipasi. PROPOSAL (1) PROPOSAL FOR CRS TO PARTNER WITH INDONESIAN ASSOCIATION OF GEOLOGIST (iagi) IN GEOPHYSICAL GROUND WATER MAPPING IN ACHEH BARAT Background The Indonesian Association of Geologist ( IAGI ) have a team who have been funded by RIO TINTO to drill 10 boreholes in Meulabo area. The team have finished the ten boreholes are due to leave within the next two weeks. There are two parts to the team. A drilling team who are operating a rotary rig only capable of drilling to 60m depth. The other part of the team consist of geologists doing borehole logging, down the hole geoelectrical logging and surface geoelectrical surveys. They consist of three geology graduates (volunteers) and one post graduate. They have all graduated from the geology department in Medan University. They have conducted extensive geoelectrical surveys in Samatiga and Meurabo in West Acheh which provides information about the hydrogeology down to 150m depth. GEOEXPERT AG GEOELECTRIC AND GEOSEISMIC SURVEY CRS WATSAN department in Meulaboh are proposing that CRS fund some of these geologists to work alongside a Swiss geophysical surveying company Geoexpert ag. This company will be conducting combined geoelectrical and geoaccoustic surveys in Meulaboh from July 11th - 24th. Caritas Swiss and CRS are paying the Swiss team to do these surveys. The purpose of the surveys is to understand the hydrogeology of the area where many thousands of tsunami victims are being relocated. It will help in identifying where to drill production wells which can supply good quality water to the town's water supply. Also further understanding of the aquifer and to assess whether the traditional drilling methods will cause contamination of the deep aquifer. UNICEF GEOELECTRICAL SURVEYING AND DRILLING RIGS UNICEF are bringing a Canadian geoelectrical surveying team with advanced geoelectrical equipment. UNICEF are also bringing drilling rigs. They are looking for local partners who can be trained to operate the equipment which will be left in Indonesia. The aim is to develop long term 'local' capacity in this area. The IAGI geologists would be suitable candidates for operating the surveying equipment. The IAGI drilling team may be suitable candidates for operating the UNCEF supplied drilling rigs. CRS INVOLVEMENT CRS could fund the IAGI geologists to work alongside the Swiss geophysical surveying team as work experience. They can help in the interpretation of the maps produced. They could then conduct surveys using their own equipment along the same transects as the Swiss and develop a correlation between their own data and the more advanced Swiss data. This correlation with more advanced equipment and the experience gained would improve their mapping. CRS can then pay the IAGI geologists to extend the survey to other CRS shelter areas and the CRS compound etc. They could also work in Arongan which the Swiss company cannot get to. CRS and other NGO's have had difficulty drilling in Arongan. They often hit formations containing arsenic or gravels which the hand drilling equipment cannot cope with. When the UNICEF drilling rigs arrive CRS could pay the IAGI drilling team to operate it. Other benefits of CRS involvement in the project a.. The IAGI geologists have been working as volunteers so would only need costs covered and some wages so CRS could then afford to do extensive mapping in their shelter areas. b.. Partnering with UNICEF, CARITAS SWISS and IAGI as part of a large project CRS can take credit for large numbers of beneficiaries in areas mapped and for production wells which will possibly supply the whole of Meulaboh. c.. Finding our about the hydrogeology of the area in particular whether the traditional drilling methods cause contamination of the deep aquifer will fufill CRS obligations to include Environmental Impact Assessment in projects. d.. The capacity building element of this project fulfills CRS obligation to long term Sustainability e.. CRS staff develop an intimate knowledge of the use of geophysical surveying methods which could be used in other areas URGENCY OF THE PROJECT IAGI geologists have run out of funding and are due to go back within next 2 weeks. The Swiss geosurvey company are starting in 5 days. We will need time to negotiate with IAGI although they were already looking for someone to continues their funding. PROPOSAL (2) Hydrogeological mapping of Meulaboh using Combined Geophysical and Geoelectrical surveying Summary: this document is a request for funding to partner in an SDC geophysical mapping project of Meulaboh Background Caritas Swiss with Swiss Dovelopment Corperation (SDC) have a Swiss geophysical surveying company arriving on July 11th to create hydrogeogical maps of Meulabo. The company Geoexpert ag will be conducting geophysical and geoelectric surveying to map the areas hydrogeology to a depth of 200m. They will then interpret the results producing color maps and descriptions of the various ground formations. They will then recommend areas suitable for drilling 6 deep production boreholes producing about 5l/s or 432m3 per day. All six boreholes would produce enough water for 50,000 people. These boreholes will supply the PDAM mains water network. The Existing PDAM water source is river water which requires huge amounts of chemical for treatment costing over $150,000 per year. PDAM do have some production boreholes but only one is used due to the high iron content and lack of appropriate water treatment equipment. The geophysical team will spend 11 days surveying 7 km of transects for water exploration purposes. They will be able to pick up formations less than 2m wide. SDC Hydrogeologist Willie Finger is hoping to find buried river beds, which can yield large amounts of good quality water. Geophysical maps have been obtained from The Indonesian Association of Geologists (IAGI) in Jakarta and there is good data for some surrounding area but a lack of data in Meulaboh. Large scale geological maps have been obtained for Achet Barat but they lack detail. Justification of CRS involvement SDC are paying for the team to fly over with large equipment to do 11 day of surveying in Meulabo. Geoexpert ag are willing to stay for up to a week extra to do surveying for CRS WATSAN department. For CRS to get the company to do extra work in our areas we pay: a.. Price per km for seismic b.. Price per km geoelectric c.. combined cost per km (Also we will pay for hotel bills for team) a.. The team can do about 4km surveying per week At the moment I am proposing to pay the company to do approximately a km surveying We could do surveying starting in the area some of PDAM's existing tubewells which have an iron problem. We will measure the boreholes water quality and work out an association between aquifer formation and water quality. Surveying would continue into an adjacent area where CRS is building new houses for 1000 people relocating from Rundeng to Lapang also there are new houses being built nearby. Soon a population of 5000 people and growing is expected requiring water. One good borehole could supply all these people with room for growth. Shallow wells typical of the area were tested and had very high iron of 5units (gov limit 0.3units) also the shallow water can easily be contaminated by septic tanks. Advantages of large borehole The large boreholes can produce 5l/s as opposed to a tube well producing 0.5l/s. Also they can last for longer and be cleaned more easily. a.. One good source is easier to treat and monitor than many. b.. Do not cause contamination of aquifer unlike shallow ones which may. c.. Boreholes cost more than $10,000 to drill d.. Small tubewells cost more $1500 Other benefits of CRS involvement in the project a.. CRS can take credit for being part of big hydrogeological mapping project b.. Fulfills our obligation/plan to support PDAM c.. CRS staff will be included in assessment of results and develop knowledge of use of geophysics. The rest of the survey being paid for by Caritas Swiss, will be done near CRS areas eg. Kampong belakang. Pangong etc. d.. We can invite staff from Banda University to do work experience. UNICEF are planning to bring geoelectrical equipment in the next few months and collaborate with Banda Acheh university to train such staff to use the equipment and develop long term geophysics capacity in the area. This will kickstart the geophysical project. e.. UNICEF will see us as a major player in the geophysical mapping and production well drilling project. They are bringing mechanincal drilling rigs to Meulaboh (the first) in the next few months and are looking for partners and people to operate the rigs. f.. Once the area is mapped the information will be available on the UN HIC website for all NGO's and any other players to see for decades to come. Urgency of project It is not a priority to do this mapping right now as we have emergency water supplies to get on with. However the opportunity is here now. The company needs to book their return flights so they need to know by July 1st (today) whether we want hire them The maps will help us plan the WATSAN infrastructure so that emergency work complements the permanent systems so that we don't end up doing things twice
