“…A widespread threat to groundwater quality is coastal marine intrusion (Stein et al 2022; this issue), influenced by climate change (sea level rise) and increased groundwater withdrawals in coastal regions, resulting in water quality deterioration and ecosystem degradation.…”

Groundwater’s role in maintaining the well-being of the planet is increasingly acknowledged. Only recently has society recognised groundwater as a key component of the water cycle. To improve public understanding and the proper use of groundwater, the hydrogeological community must expand its efforts in groundwater assessment, management, and communication. The International Association of Hydrogeologists (IAH) intends to help achieve the United Nation’s water-related Sustainable Development Goals (SDGs) by the adoption of innovative hydrogeological strategies. This essay introduces a topical collection that encapsulates IAH’s 2022 ‘Year for Groundwater’.

“…Numerical modelling has been extensively applied to manage SWI around the globe (e.g. Andersen et al, 1988 ; Bobba, 2002 ; Dhar & Datta, 2009 ; Giambastiani et al, 2007 ; Lee et al, 2023 ; Stein et al, 2023 ). All these studies used numerical modelling techniques to provide optimal SWI management strategies for coastal aquifers.…”

Small island countries like Vanuatu are facing the brunt of climate change, sea level rise (SLR), tropical cyclones, and limited or declining access to freshwater. The Tagabe coastal aquifer in Port Vila (the capital of Vanuatu) shows the presence of salinity, indicating saltwater intrusion (SWI). This study aims to develop and evaluate effective SWI management strategies for Tagabe coastal aquifer. To manage SWI, the numerical simulation model for the study area was developed using the SEAWAT code. The flow model was developed using MODFLOW and the transport model was developed using MT3DMS. Whereby SEAWAT solved flow and transport equations simultaneously. The model was calibrated, and different scenarios were evaluated for the management of SWI. The SLR was also considered in the model simulations. The results indicated that increased population, pumping rates, and SLR affect the SWI rates. To manage the SWI, we introduced hydraulic barriers like barrier wells and injection wells which effectively managed SWI in Tagabe coastal aquifer. The results from this study are significantly important whereby, the water managers, site owners, and governing bodies can use the management strategies presented in this study to create policies and regulations for managing SWI rates in Port Vila. Additionally, the water industry, private businesses, and investors who wish to extract groundwater from the Tagabe can use this study as a reference for daily or yearly freshwater production rates without the risk of SWI.

“…One of the most notable of these obstacles is high iron content, which is a serious problem in the research areas. Other disadvantages include seawater intrusion into coastal aquifers and the presence of underground saltwater reserves (Stein, et al, 2023).…”

Groundwater Use in Yenagoa: Impact on Residential Development and Investment

In the oil-producing metropolis of Yenagoa and its surroundings in Bayelsa State, Nigeria’s Yenagoa Local Government Area (YELGA), groundwater is the main and only safe source of water. As the capital of Bayelsa State, the city experienced rapid development, resulting in an influx of people and a subsequent freshwater deficit due to increased oil production and groundwater pollution. For the sustainable growth of water resources, preventing water or piezometer level fluctuations and quantitatively estimating the area’s available water supplies are crucial. To meet the water needs of the population, boreholes are dug using rotary technology and cable devices. The size of the borehole, the type of construction, the type of material used (casing and screen), and the availability of sachet water are some of the many factors that affect the cost of constructing a water borehole in Yenagoa and its environs. This study shows that the location of the study area in the riverine Niger Delta area of Nigeria makes the construction of boreholes more expensive. Data on the cost of drilling boreholes in the exhibited area shows a significant increase over time. It is shown that the long economic life of drilled borehole depends on monitoring of aquifers and wells, as well as maintenance of wells, pumps, and accessories, all of which prove inadequate.
