===A history of hydrogeological investigation and information in DRC===
  
To date, there has been no systematic hydrogeological exploration in the DR Congo. Some hydrogeological data have been collected in particular regions of the country, by various agencies - including REGIDESO (Regie de Distribution d'Eau de la Republique Democratique du Congo - the national water supply and sanitation agency), NGOs and mining companies.

To date, there has been no systematic hydrogeological exploration in the DR Congo. 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.  
  
A number of reports have been published since the 1950s that describe aspects of the hydrogeology of the DRC. Although they provide much essential information, they all suffer from a lack of field data from hydrogeological tests (e.g. borehole pumping tests).

In 1957, [http://www.bgs.ac.uk/africaGroundwaterAtlas/atlas.cfc?method=ViewDetails&id=ZR1041 Snel] presented the first country-scale general hydrogeological overview, and compiled a [https://fishy.bgr.de/whymis/images/region/congo_dem_rep_rwanda.jpg hydrogeological map] (available to view as a scanned image from the BGR [https://geoviewer.bgr.de/mapapps/resources/apps/whymap/index.html?lang=en&tab=whymap_gwr WHYMAP] website). Though the report is very rich and descriptive, it does not include any quantitative 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.

During the 1980s there was groundwater research in several areas, with a view to developing drinking water supplies for key urban areas. This included the central sedimentary aquifer basin (e.g. Boende, Lisala and Basankusu) and areas where Precambrian formations are dominated by limestones (e.g. Mbanza-Ngungu, Likasi and Lubumbashi). 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.
