Investigation and control of seawater intrusion in the Eastern Nile Delta aquifer considering climate change
Seawater intrusion is considered one of the main processes that degrade water quality by raising salinity. Over-pumping and decreasing recharge are considered the main causes of saltwater intrusion. Moreover, climate change and sea-level rise accelerate saltwater intrusion. In this paper SEAWAT code was used to study groundwater flow and seawater intrusion in the Eastern Nile Delta aquifer ...

A new frontier in Texas: managing and regulating brackish groundwater
The challenge of providing access to clean water is visible in Texas, where chronic drought coincides with increasing water demand. The 2012 Texas State Water Plan reports a 2,700 million cubic metres (MCM) gap between freshwater supply and demand in 2010, a number predicted to grow to 3,100 MCM by 2060. Due to the difficulty of reducing water demand, policy makers and water providers are ...

Why it’s time to elevate groundwater
Groundwater stored in the earth’s crust underpins all our lives – the ultimate source of freshwater for billions has become victim of over-extraction and the ultimate sink for pollutants. For too long, not enough has been done to regulate the use of this precious, on-demand resource and manage disposal of waste. If rates of groundwater depletion have tripled in the past 3 decades, ...

Threats to Miami’s Water Supply
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. The shallow Biscayne Aquifer faces saltwater intrusion as well as other dangers Rising sea levels caused by climate change threaten to submerge $200 billion worth of Miami real estate by century’s end, ...

BOS 200, Hydrocarbons Application at an Active Gas Station - Case Study
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. Over the course of 4.5 years of monitoring, 92.4-99.9% reductions in Benzene were achieved in the treatment area (replaced) monitoring wells. Validation ...

Towards sustainable water resource management: a case study in Limassol Cyprus
Sustainable water resource management has become critical in the development of areas where renewable freshwater resources are highly constrained. This paper describes a new methodological approach of integrated water management strategy, based on the principles of Integrated Water Resources Management together with the provisions of the EU Water Framework Directive. The method was successfully ...

Assessment of groundwater quality using geographical information system (GIS), at north-east Cairo, Egypt
The present investigation has been conducted to delineate the hydrogeochemical and environmental factors that control the water quality of the groundwater resources in the north-east of Cairo. 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 ...

Factors affecting the performance and risks to human health of on-site wastewater treatment systems
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. However, aerobic systems in operation do not always perform to design standard; while this is often blamed on lack of maintenance, few ...

Brackish Water as a Resource
There’s a great deal of talk and debate about the value of treating brackish water, or water that is more saline than fresh water, but not quite as saline as seawater. 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 ...
