"Assessment of groundwater resources yields knowledge necessary for their informed management and governance. Assessment means more than hydrogeological characterisation alone: it includes all other aspects (e.g. social, economic or environmental) that are needed for understanding of the resource and its state, in accordance with purpose of the assessment. Since groundwater resources are subjected to change, possible changes and their impact need to be assessed on regular basis." (International Groundwater Resources Assessment Centre (IGRAC). n.d)

With increasing populations, groundwater abstraction also increased as about half of the global urban population access their water through aquifers (Foster et al., 2020). With 74% of the world population depending on it for safe drinking water services and sanitation (WHO and UNICEF, 2021), groundwater plays a vital role in health.
