Geohydrology is the study of groundwater and its physical and chemical interactions with the physical environment. Our services include monitoring groundwater levels, purging boreholes, water sampling for chemical analysis, applying the SANS drinking water standards to the water quality results, management of monitoring database, producing monitoring maps and report writing for submission to DWA, sampling of surface water at various monitoring points.
Groundwater resource development for the community water supply and sanitation programme is seen as a viable option not only for drought relief projects but to augment the municipal supply, especially in communities without the necessary infrastructure. We assist with the siting of the borehole, drilling of the borehole, pump testing and installation.
