Abstract: Trap and Treat® BOS 200® was applied at an active gas station in Europe with elevated dissolved phase contamination and NAPL impacts to protect the primary aquifer and cut off the dissolved phase plume from migrating off-site. ...
Because the original facility was permitted as part of the mining operation, a new Aquifer Protection Permit was required. In the Design of the New Facility, Santec focused on three key elements during the design phase of the project; 1) Class B+ reclaimed water quality standards for effluent, 2) Minimization of operating expenses and 3) Maximize value of ...
Satisfying Two Needs With One Resource Keeping track of water consumption within a watershed or aquifer region requires a centralized organization to monitor data shared from a variety of water consumers. ...
Restoring flow of fresh water into the Everglades would help protect Miami’s aquifer, but projects like a planned reservoir have been met with problems including uncertain funding. ...
This drew the ire of surrounding cities due to the overuse of a shared aquifer. Today, water use has been cut to 117 gallons per person per day, and San Antonio has earned the reputation of being forward-thinking when it comes to sustainable water management. ...
Brackish water can result from the mixing of seawater with fresh water, as in surface waters such as estuaries or other watery ecosystems, or it can occur underground in aquifers. Salinity Levels Although these definitions may seem vague, there are some precise definitions for salty waters. ...

From the ecological perspective, the facility presented in the study has proven to be an effective tool for protecting local aquifer areas. ...
In this paper SEAWAT code was used to study groundwater flow and seawater intrusion in the Eastern Nile Delta aquifer considering four scenarios of climate change including sea-level rise, increasing abstraction, decreasing recharge and the combination of these scenarios. ...
Due to the difficulty of reducing water demand, policy makers and water providers are evaluating new sources, including brackish groundwater for desalination or direct use. It is estimated that Texas aquifers contain more than 3,300,000 MCM of brackish groundwater, which, if converted to fresh water, could meet current consumption needs for 150 years, albeit at a greater cost. ...
A complementary approach based on hydrogeochemistry and a geographical information system (GIS) based protectability index has been employed for conducting this work. The results from the chemical analysis revealed that the groundwater of the Quaternary aquifer is less saline than that of the Miocene aquifer and the main factors that control the ...
Self-supply, through the use of wells, from polluted aquifers in urban and rural areas is widespread, but un-reported. The impacts are all too apparent in the densely populated urban slums and rural communities that often live just centimeters above polluted soil and rock. Out-migration of poor farmers who are no longer able to access deepening groundwater tables has been a ...
This paper presents the development of a coupled transient finite element model for simulation of fluid flow and solute transport in soils and its application to study seawater intrusion in Gaza aquifer. The effects of likely sea level rise due to climate change and over-pumping on seawater intrusion in Gaza aquifer are studied using three scenarios: rise in sea ...
The remediation methods discussed are air oxidation, reactive barriers, utilisation of deeper aquifers and sanitary protected dug wells. To the best of our knowledge no technology is available capable to remove arsenic from water at efficient, economic and commercial levels. ...

Aerobic wastewater treatment systems (aerobic systems) are the preferred choice in a region overlying a karstic aquifer used for drinking water supplies, as they are thought to provide better protection to groundwater and human health than standard septic systems. ...
The method was successfully applied in the Limassol area of Cyprus and helped to counteract the growing demands for water by the permanent and seasonal population and traditional agriculture. The aquifers of the region were protected as groundwater exploitation was kept to sustainable levels, while the water supply to the region was stabilised. ...
Results show that a Permeable Adsorbing Barrier (PAB) made of Aquacarb 207EA can protect a shallow aquifer from topsoil Cr(VI) leaching even during heavy rainfalls and that Cr(VI) is desorbed in dry periods, when clean water crosses the PAB, without any dangerous release in the aquifer.Keywords: groundwater remediation, heavy metals, permeable reactive barriers, ...
Recharging the AquiferIn some places Aqueonics actually discharges treated wastewater to subsurface beds for recharging the aquifer. The secondary protection of the water source is the distance from the bottom of the beds to the physical aquifer, which means that there is a tremendous amount of natural filtration taking place in the ground once ...
In fact, through improvements in efficiency and conservation, we can meet California’s future water needs while increasing the amount of water returned to the natural environment – thus ensuring that natural systems are protected and underground aquifers recharged. Another benefit: Saving water saves money – for water providers, consumers, and the state as a ...
