“…In the MRD, groundwater degradation often arises by cause of native processes such as seawater intrusion from the tidal regime of the East Sea [23]. Another study also pointed out that the evaporation processes were considered the main factor affecting groundwater chemical composition variation in the MRD [24].…”

Shallow aquifers in the Thanh Phu coastal area in Ben Tre Province are increasingly withdrawn for domestic and irrigation purposes. However, groundwater resources here are declining in quality due to the effects of seawater intrusion and anthropogenic activities. It requires an understanding of the groundwater origin and changes in water quality to protect local groundwater resources. By applying the hydrogeochemical approach, the origin and quality of groundwater here have been clarified. A total of 35 water samples were collected during the 2023 dry season. The laboratory analysis included 16 ions. The results show that the groundwater water types are Ca-Cl, Ca-Mg-Cl and Na-Cl, with the domination of the third pattern. Hydrochemical characteristics have shown evaporation, silicate weathering, cation exchange and marine effects as the vital processes governing the mineralization of regional groundwater. Most of the water samples are of poor quality, not adapting to domestic water standards according to the National Technical Regulation on Domestic Water Quality and WHO 2011. It requires water treatment before being used for domestic purposes. However, the SAR, Na%, PI, KR and EC values displayed that groundwater here was still acceptable for irrigation purposes, demonstrating the prospect of using groundwater for agricultural purposes in the study area.

“…The vulnerability of the aquifer to seawater intrusion has been calculated using an index called GALDIT, which is based on six parameters: groundwater occurrence, aquifer hydraulic conductivity, height of groundwater level above sea elevation, distance from shore, impact magnitude of the current seawater intrusion and aquifer thickness [10]. For evaluating the possible long-term effects of groundwater use on seawater intrusion, GALDIT has been extensively utilized [8,[11][12][13][14][15][16][17][18]. Using its hydrogeological data, the GALDIT indicator model is applied to a region of interest, assigning ratings based on the particular conditions, including seawater intrusion.…”

This paper presents the investigation of groundwater vulnerability to seawater intrusion of the aquifer system in the coastal area of Laspias River, NE Greece, for the year 2023, by applying the GALDIT, SITE and SIVI methods, in the context of the groundwater management of the area. The relevant research works include the collection and analysis of data and information regarding the geological and geomorphological environment, as well as the hydrogeological system of the area. The calculation of the GALDIT, SITE and SIVI indices values is described, and the results from the application of the methods are presented, as well as the design of relevant groundwater vulnerability maps of the study area. This paper concludes with findings and proposals useful for the reliable assessment of the hydrogeological regime of the wider study area.
