The Global Water Initiative (GWI) was an action-research and advocacy programme that ran from 2008-17. The project is now closed. This site is no longer being updated, but allows access to GWI outputs until 1 October 2020 when it will also close. After that date, information about the project and core GWI technical publications will continue to be available from the IIED website and Publications Library.
Borehole water quality in the Sirba sub-basin, Burkina Faso
GWI tested the water quality of 50 boreholes in Sirba, Burkina Faso, examining an extensive range of physical and chemical properties. This report documents our findings, explaining that 42 of the 50 provide good quality water, with the remaining 8 providing average quality water. Our measurements raised some specific concerns which led the water from several boreholes to be judged unfit for human consumption. We conclude that regular follow-up assessments are crucial, given that chemical concentrations can fluctuate greatly over time.
