Deteriorating groundwater quality, as represented by high nitrates, in the Colline province of Benin, West Africa was
identified by the Benin national water agency, Direction Hydraulique. For unknown reasons the Colline province had
consistently higher nitrate levels than any other region of the country. In an effort to address this water quality issue, a
collaborative team was created that incorporated professionals from the Universit‚ d'Abomey-Calavi (Benin), the University of
Notre Dame (USA), Direction l'Hydraulique (a government water agency in Benin), Centre Afrika Obota (an educational NGO in
Benin), and the local population of the village of Adour‚koman.
The goals of the project were to: (i) identify the source of nitrates, (ii) test field techniques for long term, local
monitoring, and (iii) identify possible solutions to the high levels of groundwater nitrates. In order to accomplish these
goals, the following methods were utilized: regional sampling of groundwater quality, field methods that allowed the local
population to regularly monitor village groundwater quality, isotopic analysis, and sociological methods of surveys, focus
groups, and observations.
It is through the combination of these multi-disciplinary methods that all three goals were successfully addressed leading to
preliminary identification of the sources of nitrates in the village of Adour‚koman, confirmation of utility of field
techniques, and initial assessment of possible solutions to the contamination problem.
