The only available hydrogeological data are specific to particular regions of the country, produced by REGIDESO (Regie de Distribution d'Eau de la Republique Democratique du Congo - the national water supply and sanitation agency), or by NGOs or mining companies. |

Although they provide much essential information, they all suffer from a lack of field data derived from hydrogeological tests. |

Though the report is very rich and descriptive, it does not present data on aquifer characterisation. |
Waleffe (1985) provided an outline of the hydrogeology of the lower Rusizi aquifer, which was later re-interpreted by Hakiza (2002), who provided some values for aquifer parameters for the lower Rusizi to the north of Lake Tanganyika, including on the DRC side of the border. | Waleffe (1985) provided an outline of the hydrogeology of the lower Rusizi aquifer, which was later re-interpreted by Hakiza (2002), who provided some values for aquifer parameters for the lower Rusizi to the north of Lake Tanganyika, including on the DRC side of the border. | ||

Results from this research are summarised in a [http://www.bgs.ac.uk/africaGroundwaterAtlas/atlas.cfc?method=ViewDetails&id=AGLA060006 United Nations report] (1989). |
A Nile project report (2010) presents a summary of Snel (1957) with some additional aquifer properties data from an unknown source. Although widespread, these data are still not representative of the whole country. | A Nile project report (2010) presents a summary of Snel (1957) with some additional aquifer properties data from an unknown source.
