Science is a living document; it grows and expands as more information becomes available and our knowledge grows. It makes use of hypothesis, experiments, observations, and measurements. Groundwater scientists have a difficult task. They work in a system that is not visible, and they cannot take it into a laboratory to study. They use geophysical methods and drill boreholes to get an idea of the groundwater system that they are studying.

Small water treatment plants are defined as water treatment systems that have to be installed in areas which are not adequately serviced and do not normally fall within the confines of urban areas. They are therefore mostly used in rural and peri-urban areas and include chlorination plants for water supplies from boreholes and springs, small treatment systems for rural communities, treatment plants of small municipalities and treatment plants for establishments such as rural hospitals, schools, clinics, forestry stations, etc.

TALK ABSTRACT It’s commonly accepted that climate change will be experienced though water, particularly in developing countries. Several studies relating to the impacts of climate change on surface water have been undertaken while very little research exists on the potential impacts on groundwater.

Recent trends in mining and exploration are set to further accelerate the demand and growth of 3D geological modelling software. These trends include the inevitable increase in cost per ton of resource and global economic slowdowns. These require companies to constantly cost-cut during extraction and to improve resource delineation. Add to this the trend that new discoveries are deeper and in more structurally-complex setting, and it’s apparent that a great deal of attention needs to be focused on getting the geometry of a deposit, as early as possible in the exploration and mining value chain, correct.

Alongside the effects of climate change and anthropogenic factors, natural climate cycles have considerable impacts on the hydrologic cycle. In this study, we look at how global climatic oscillations cycles, like El Niño–Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) affect total water storage and groundwater storage in the Orange-Senqu River Basin by analysing two large aquifers: the Stampriet Transboundary Aquifer System (STAS) shared between Botswana, Namibia and South Africa, and the Karoo Sedimentary Aquifer shared between Lesotho and South Africa.

Public domain borehole information in South Africa is generally stored in the National Groundwater Archive (NGA) and the Groundwater Resources Information Project (GRIP) databases of which both are centralized databases. The GRIP database is updated by the Department of Water and Sanitation, but only covers one of the nine provinces. The NGA on the other hand covers the entire country, however, there is a backlog of borehole information that needs to be captured, and it has limited time-series data.

Groundwater is not private property, and the use of groundwater requires a water use license or a general authorization. This is imperative for most environmental impact assessments, requiring even ongoing monitoring for the foreseeable future.

The Groundwater Division and its partners are presenting a groundwater field school for postgraduate students and industry professionals. The four-day field school aims to cover appropriate field methods by Introducing or refreshing appropriate basic theory Exposing attendees to the actual field methods in real field conditions Analysing and interpreting field results based on appropriate guidelines, standards, laws, and requirements The field school comprise four modules and attendance can be p/day, p/theme or for the full package: Day 1: Investigation and Siting (hydrogeology and hydrostratigraphy; siting of

Investigation for cemetery sites requires the detection i. of a wide range of different contaminant groups, ii. at typically very low concentrations (if present), iii. as well as natural and geological impacts on the proposed developments; and iv. with important safety and human and ecosystem health effects if undetected. The issues of internment and how we deal with the deceased in general transect disciplines of natural science, engineering, and social science. Given the sensitive nature of internment and the established notions of acceptable practice at an individual and personal level, assessment
