GROUNDWATER EXPLORATION AND MANAGEMENT, NORTHEASTERN BRAZIL

 Call for expressions of interest


Introduction

The Geological Survey of Canada (GSC) with the support of the Canadian International Development Agency (CIDA) is about to initiate a three-year technology transfer program in the area of groundwater exploration and management in an attempt to bring long term solutions to the water supply problems in drought-stricken northeastern Brazil (see map). The GSC and its Brazilian partners, the Geological Survey of Brazil (CPRM) and the Brazilian Groundwater Association (ABAS) are seeking collaborators in the project from the Canadian private sector and public institutions.
 
 

Context

About 1 million km2 covering parts of eight states of northeastern Brazil are in the midst of one of the worst droughts this century, which has devastated the region’s agriculture and has generated genuine hardship for a large part of its 25 million or more inhabitants. About half of the area, underlain by Precambrian crystalline rocks, is particularly hard hit. Surface water is scarce in these regions, and the population relies heavily on groundwater, which, in this type of terrain, is confined to open fracture aquifers. But the groundwater resources have been poorly utilized and managed, and do not currently meet the demand.
 
 

About half of the 13,000 rural wells in the state of Ceará alone are not producing. The majority were drilled without the benefit of adequate groundwater exploration tools. Compounding the problem of quantity is the fact that about 80% of the wells in crystalline bedrock produce brackish water that is unfit for human and animal consumption, or for irrigation. Desalinization (reverse osmosis) apparatus have been installed on some wells, but for the majority, yields are too low to justify the installation such costly equipment.
 
 

The Brazilian government has put in place a number of emergency relief measures to help the population live through this difficult period: food distribution; indiscriminate drilling of a large number of new wells; construction projects and repair to dams, mostly to create employment; facilitating private loans for minor waterworks projects; and increased distribution of drinking water by tanker trucks. These measures were clearly meant for the short term and offer no lasting benefits. What is really needed are long term solutions that will permit the population to cope during periods of drought without the need for government handouts or expensive and inefficient emergency measures.
 
 

Canadian technologies

The proponents of the technology transfer program believe that the groundwater resources of northeastern Brazil can be exploited more efficiently by introducing modern exploration and management techniques. Geophysics and remote sensing applied to the search for fractured bedrock aquifers will constitute a prime component of the program. But other areas are equally important. For example, technologies to deal with the high salinity problem; technologies to rehabilitate existing water supply systems and improve yields; applicable and innovative techniques of well construction, water storage, pumping, water treatment, distribution, etc. The program will also support research that can be shown to be pertinent to the groundwater problems of northeastern Brazil. This could include such disciplines as hydrogeology, structural geology, geochemistry, groundwater modeling, borehole logging, etc.
 
 

The need for better groundwater exploration and management tools is recognized by the majority of public and private organizations involved with water issues in northeastern Brazil. Even though most water related problems in Canada differ greatly from those in northeastern Brazil, there is no doubt that relevant knowledge, experience and technologies exist in Canada, that could help improve living conditions in that region.
 
 

Technology transfer

The proposed program includes a technology transfer component, to be funded by Canada, and a follow-up/implementation component to be funded by Brazil. The present call for expressions of interest is for the technology transfer component, but organizations that become involved in the transfer of technology will be in a good position and could eventually take part in the implementation component.
 
 

The target audience for the technology transfer includes all the Brazilian organizations and individuals who are involved in finding, supplying, managing and researching the groundwater resources of northeastern Brazil. Groundwater exploration is currently carried out by firms of consultants working under contract to large public waterworks companies. Personnel from these organizations will take part in the technology transfer exercise. Personnel and students from earth science departments of several universities in the northeast, and the Geological Survey of Brazil will also be invited.
 
 

The transfer of technology will take the form of workshops, seminars and short courses that should include classroom-style presentations (theory, case studies, etc.) and field demonstrations and/or pilot-scale projects in Brazil. All practical work will be geared towards solving real problems in the community. The technology transfer component of the program will not fund the purchase of equipment, but will cover equipment rental, either in Brazil or in Canada and related transportation costs. The main centers of operation in Brazil will be Fortaleza in the state of Ceará, Recife in Pernambuco and Natal in Rio Grande do Norte. Other centers may also be included depending on local needs and the demand.
 
 

Canadian technology will also be transferred through training of Brazilian personnel in Canada for periods ranging from a few weeks to a few months. This may include laboratory as well as field oriented programs.
 
 

Opportunities

Firms and individuals who will have responded to this invitation, and perhaps others, will have the opportunity to bid on small, short-term contracts to carry out technology transfer projects in Brazil and in Canada as indicated above. These contracts will be let by the Geological Survey of Canada.
 
 

For the longer term, participation in the program will allow individuals and companies to showcase their expertise and their technologies in an area that is vital for Brazil and at the very top on the list of government priorities. An enormous amount of the country’s resources are presently being pumped into the affected regions in the form of relief programs. There is little doubt that any Canadian technology that can be shown to bring benefits will be examined very seriously by the Brazilian authorities.
 
 

Expressions of interest

The GSC, CPRM and ABAS would like to hear from any Canadian organization, private or public, and individuals who may be able to make a contribution to this program. We are not requesting full proposals at this stage, but only a short statement indicating what the organization or individual can offer along with any relevant experience they might have. Relevant experience can include a vast array of groundwater related experience, but we are particularly interested in expertise in fractured aquifer environments and/or in semi-arid regions. Having worked in Brazil previously and, although not essential, having a working knowledge of Portuguese, or even Spanish, will be considered important assets.
 
 

Respondents should send relevant material by mail, fax or e-mail, directly to the undersigned.
