  journal={Hydrogeology Journal},
Saltwater has intruded into many of the coastal aquifers of the United States, Mexico, and Canada, but the extent of saltwater intrusion varies widely among localities and hydrogeologic settings. In many instances, the area contaminated by saltwater is limited to small parts of an aquifer and to specific wells and has had little or no effect on overall groundwater supplies; in other instances, saltwater contamination is of regional extent and has resulted in the closure of many groundwater… 
Salt Groundwater Intrusion in the Pleistocene Aquifer in the Southern Part of the Red River Delta, Vietnam
Fresh groundwater was found in the Pleistocene aquifer in the southern part of the Red River Delta in 70‟s of last century. It is located mainly in the south of Nam Dinh province and small part in
Sea Water Intrusion into Coastal Aquifers-Concepts, Methods and Adoptable Control Practices
Seawater intrusion is one of the most wide-spread and important processes that degrades groundwater quality by raising salinity to levels exceeding acceptable drinking water and irrigation standards,
Studying the vulnerability factors of coastal aquifers due to sea saline water intrusion
In most coastal areas, groundwater is considered as one of the most important resource of usable water supply for agriculture, drinking and industry. In these areas, the fresh water resources are
Groundwater Throughflow and Seawater Intrusion in High Quality Coastal Aquifers
It is demonstrated how hydraulic anisotropy will impact on the landward extent of seawater for a given groundwater throughflow, and extremes in hydraulic properties, and rapid changes in groundwater chemistry are revealed.
Groundwater level observations in 250,000 coastal US wells reveal scope of potential seawater intrusion
It is found that 15% of the US coastline is affected by landward hydraulic gradients conducive to seawater intrusion, and a substantial fraction of the East Coast and Gulf Coast, and also parts of the West Coast where groundwater pumping is high.
Continental patterns of submarine groundwater discharge reveal coastal vulnerabilities
A high-resolution continental-scale analysis of fresh groundwater discharge along the coastline of the United States unveils hot spots for contaminant discharge to marine waters and saltwater intrusion into coastal aquifers.
Association of geomorphic features with groundwater quality and freshwater availability in coastal regions
Seawater intrusion into coastal aquifers is a global problem as it limits the freshwater availability in coastal regions. A study has been conducted with the aims to identify the processes
Origin and extent of fresh groundwater, salty paleowaters and recent saltwater intrusions in Red River flood plain aquifers, Vietnam
A model has been established on the origin and extent of fresh groundwater, salty paleowaters and saltwater from recent seawater intrusions in the Red River flood plain in Vietnam. This was done with
Seawater intrusion and coastal aquifer management in China: a review
Abstract Seawater intrusion has been an important topic in hydrogeology in China in recent decades. The rapid growth of the population and economy in the coastal regions has been consuming a


Salt-water intrusion and nitrate contamination in the Valley of Hermosillo and El Sahuaral coastal aquifers, Sonora, Mexico
Abstract The Valley of Hermosillo coastal aquifer, state of Sonora, northwestern Mexico, has been over-exploited for the last four decades, in order to maintain agricultural activity in one of the
Seawater Intrusion in the United States
The growth of industry and population in the United States during most of its history has been concentrated in coastal areas having good access to ports. Thus, those coastal areas that also had
Salt Water Intrusion in the Summerside Area, P.E.I.
Salt water intrusion is an acute problem in the coastal areas of Prince Edward Island. In the town of Summerside, ground-water supplies are developed from an aquifer hydraulically connected with the
Sea Water Intrusion in California
PRIOR to 1900, utilization of ground water supplies was relatively unimportant in California. Rapid development since the turn of the century has created many serious problems, including overdraft
Bibliography on the occurrence and intrusion of saltwater in aquifers along the Atlantic Coast of the United States
Freshwater aquifers along the Atlantic coast of the United States are vulnerable to the intrusion of saltwater from saline waters that bound the aquifers along their seaward margins. Incidences of
The occurrence and geochemistry of salty ground water in the northern Atlantic Coastal Plain
Salty ground water underlies freshwater in the eastern part of the northern Atlantic Coastal Plain. The transition zone between freshwater and saltwater is represented in this report by a series of
Salt-water intrusion in Prince Edward Island
The numerous saline estuaries situated throughout Prince Edward Island permit high tides to carry salt water a long way inland and to penetrate the bedrock aquifer. Very little groundwater
Geochemistry of the Floridan aquifer system in Florida and in parts of Georgia, South Carolina, and Alabama
The chemical quality of the ground water in the Floridan aquifer system is determined primarily by mineral-water interaction. However, some changes in water quality have been imposed by development,
