Independent specialists and researchers from the Institute for Groundwater Studies (IGS) at the University of the Free State (UFS), in partnership with specialists from Carin Bosman Sustainable Solutions (CBSS), have been appointed by the Petroleum Agency of South Africa (PASA) to design a regional groundwater monitoring network for the Central Karoo.

A 2016 report by the Council for Scientific and Industrial Research (CSIR) titled Shale Gas Development in the Central Karoo: A Scientific Assessment of the Opportunities and Risks, recommended that “a comprehensive understanding of groundwater conditions is required prior to the commencement of exploration to ensure proper interpretation of changes in groundwater over time. [...] Monitoring data would also be used for calibration and verification of prediction and assessment models, for evaluating and auditing the success of management plans, and for assessing the extent of compliance with prescribed standards and regulations.”

The specialists employed by the IGS and CBSS to undertake the project include SACNASP-registered scientists who have expertise and experience in geohydrology and the geology of the Karoo Basin, as well as experts in water governance (including the design and development of water monitoring programmes and the evaluation, interpretation, and visualisation of water quality data), and software developers who can handle large volumes of water monitoring data. 

A groundwater monitoring network needs to generate monitoring results that can provide answers to specific management and/or governance questions asked by relevant decision makers (including landowners and those involved in national, provincial, and local government) and other stakeholders. Communication of monitoring results to these decision makers should be understandable, without being too technical, so that the outcome of any monitoring activity will lead to improved decision making with regard to groundwater management in the Central Karoo. These management questions will therefore be contingent on the needs of the decision makers, which could relate to one or more aspects of groundwater resources and/or potential activities that could pose a risk of harm to a groundwater resource. To ensure that this monitoring network is designed in a manner that will address the expectations of all stakeholders, the project team therefore calls on all relevant decision-makers and other interested stakeholders to contact them with management questions that they need to be answered by this monitoring network. Participation in the project is voluntary, and there will be no cost implications for participants.

Selection of locations that will form part of the groundwater monitoring network will to a large extent rest upon the management questions that need to be addressed by the network. Therefore, once these management questions have been collected from stakeholders, the project team will undertake geohydrological, geophysical, and water-quality assessments to determine the suitability of existing boreholes to provide answers to prioritised management questions. Where no suitable boreholes can be found to address management questions, recommendations relating to the drilling of additional boreholes for future monitoring purposes will be made. For this reason, if relevant decision makers and interested stakeholders are aware of any existing boreholes or any existing network of boreholes in the Central Karoo, the project team would appreciate and welcome any suggestions to ensure that these existing options can be investigated for inclusion in the monitoring network. 

The more management questions and information about existing boreholes the project team receives, the more beneficial the final monitoring network design will be to decision makers and landowners in the Central Karoo. 

Please contact Dr Fanie de Lange (DeLangeSS@ufs.ac.za) or Carin Bosman (info@cbss.co.za) to share your ideas, to discuss specific management questions for the monitoring network, or to inform them about boreholes that should be included and investigated for this project.
