Our Services Hydrogeological Modelling Numerical groundwater models are the best tools available to quantify  groundwater and mass balances, which can then be used to inform  decision making related to environmental impact assessments or the  optimisation of engineering designs. The project team is competent in  both finite element (SPRING) and finite difference modelling codes  (Modflow, including various interfaces). These internationally accepted modelling packages are used in a variety of applications like  numerical flow modelling to estimate mine inflow rates and associated  impacts, to define aquifer vulnerability and aquifer protection zones  around abstraction boreholes or to predict contaminant transport rates from various source types. The finite element modelling code SPRING  allows also simulating discrete fractures, undergrounding mine  workings, heat exchange as well as unsaturated flow and transport  processes. For more information on SPRING   visit: http://spring.delta-h.de/ Geochemistry The main purpose of geochemical assessments is to predict the likely  drainage and seepage water quality associated with Mine Residue  Deposits (MRD). This information is used as inputs into groundwater  flow and transport models to assess the potential pollution plume  associated with the MRD. Delta H offers mine site geochemical  investigations including Acid Rock Drainage (ARD) risk assessments  and management plans. Groundwater Impact/Resource Assessments Groundwater resources are subject to human impact in many ways  and the exploitation of groundwater is increasing everywhere. Delta H  provides specialist input into Environmental Impact Assessments  (EIA) and Feasibility Studies. These services include: Groundwater recource delineation Aquifer charactersiation Conceptual groundwater model development Cumulative groundwater impact assessments Water - Related Risk Studies The management of water resources requires consideration of the  overlapping themes of economic development, the water-energy-food  nexus, social equality, environmental protection, and institutional and  governance structures. Delta H assists decision makers at the various  levels of government, in research projects and in policy advice that  considers the full complexity of water management. Delta H also  assists private clients managing their water use and inherent water -  related risks, through measures that are appropriate for the client, for  example water foot-printing to understand supply chain risks, or  through adaption of water practices to meet standards such as the  CEO Water Mandate Spatial Data Analysis and Statistics Delta H provides a high level spatial analysis (using GIS) of large  groundwater datasets which includes proximity analysis and  identifying influencing factors on borehole productivity such as  geology, geomorphology and lineaments (e.g. dykes and faults). The  combination of multivariate statistical methods and spatial analysis of  geochemical data sets provides useful assessment of controls over  water composition and assists in the identification of possible anthropogenic influences. Training Delta H staff is actively involved in the lecturing of groundwater  modelling and geochemistry courses at Universities in South Africa  and Germany. We also offer training to the public, private and mining  sector.
