In porous aquifers, the central-to-sea cross-section highlights meteoric water dominance from rain and surface sources. Groundwater undergoes exchange-absorption with silicate minerals, enriching Ca2+ and Mg2+ (reducing Na+). Seaward, dissolution and leaching of salts in marine-origin sediments (mQ2, mQ13, mQ12-3, and mN22) prevail. The results of this paper provide necessary information for the effective management of groundwater quality.

This paper presents the geotechnical conditions, the ground improvement methodologyand quality control during construction. The control sequence is performed by vertical and then horizontal drilling holes. The method of control work after excavation (horizontal control) allows to confirm the quality of the treatment blocks and specifically the bonding between the treatment block and the diaphragm wall.

Groundwater in Xuyen Moc district is used for many purposes like irrigation, domestic and animal husbandry. In recent years, groundwater quality in the area witnessed a downward trend, especially in dry season. In this study, 06 groundwater samples were collected from mornitoring wells from Pleistocen aquifer in wet and dry seasons during 2017.

This study reviewed the latest information on the presence of PMMoV and human enteric viruses in water environments and in wastewater (water) treatment systems to evaluate the suitability of PMMoV as an indicator virus for water safety and quality. PMMoV was present in all types of waters (e.g., wastewater, surface water, groundwater, coastal water and drinking water) in greater prevalence than human enteric viruses.

The results revealed that surface water possessed more potential non-carcinogenic harmful health risks to the residents of the study area to compare to groundwater. As regards carcinogenic health risks, on average there is a possibility of 5 persons in every 106 developing cancer due to lifetime exposure to Cd through ingestion of groundwater.

Geoinformatics is application of information technology for study and management of earth resources. The salt affected soils of Gohana were mapped and evaluated using visual interpretation of IRS-P6 satellite false colour composite (FCC) image with ground survey and laboratory analysis. A total of 72 soil samples across the study area were sampled based on the quality of groundwater used for irrigation at four depths (0-15, 15-30, 30-45 and 45-60 cm). Long-term irrigation with salt affected water results in soil quality decline.

This study summarized the results of surveys for arsenic since 2008 and surveys for dissolved ions and trace elements since 2015, and described characteristics on distribution for chemical composition at the regional areas along the MR and Bassac (Hậu) River (BR). Groundwater samples were collected from existing wells in 8 provinces and 1 city. The authors used Piper and Stiff diagram that reflect the chemical composition of groundwater to respond to varying horizontal and vertical distributions.

This study investigated the current situation of groundwater use for domestic purposes and consumption. The research team collected data from several centralized water supply stations operated by the CERWASS. The team also conducted surveys and took water samples from 94 households and water supply stations. The evaluation of groundwater quality and its suitability for domestic use was also conducted. The results showed that in terms of raw water quality, most of the samples had low iron (Fe) concentration and pH value.

Groundwater-surface water interactions include the exchange of fluids and solutes between groundwater and surface water, which can affect water quality and water supply. Investigating the interaction of groundwater and surface water is essential to water managers and hydrologists for the improvement of effective waterresource policy, water resource protection and management. The effects of groundwater-surface-water exchange can occur on a variety of spatial and temporal scales.
