Groundwater Quality and Hydrochemistry

Hydrochemistry or groundwater quality / chemistry is an important aspect to understanding a hydrogeological system and in developing a confident and defensible conceptualisation.

Ground & Water Australia have significant experience in the collection of valid groundwater samples, the measurement in field of water quality data, and most importantly the interpretation of results in direct alignment with the broader conceptualisation needed to describe a system. We identify and differentiate different water species or sources, we consider mixing effects and the impacts of vertical and horizontal pressure gradients which may drive or inhibit inter-aquifer mixing effects. Comparison of groundwater against legislated and suggested guidelines aligned to intended use are also considered, and we use a range of graphical tools in the form of basic to complex graphs, GIS mapping and technical schematics to show concepts.
