Soil

Geology

The geology map shows a simplified version of the geology at a national scale. More information is available in the report UN (1988) (see References section, below).



Geology of Guinea at 1:5 million scale. For more information on how the map was developed see the geology resource page

Hydrogeology

The hydrogeology map below shows a simplified version of the type and productivity of the main aquifers at a national scale (see the hydrogeology map resource page for more details).

More information on the hydrogeology of Guinea is available in the report United Nations (1988) (see References section, below).

Groundwater management

The country has recently adopted programmes for improving water services: the National Drinking Water Supply and Sanitation Programme (NDWSSP) and the National Strategy for Development of Public Water Services in Rural and Semi-Urban Areas (SNDSPE). These programmes aim to address the current situation where local authorities have low capacity to implement their responsibility for water service projects in rural and semi-urban areas; and water services are largely being developed in a fragmented project-based way (African Development Bank Group 2013).

There is a central database with information on more than 16,000 water points - mainly boreholes - based on data from different projects that were supervised by the national water authority, but the data are not all well organised. It does, however, include more than 1000 borehole geological logs that are easy to access.


Transboundary aquifers

For further information about transboundary aquifers, please see the Transboundary aquifers resources page.
