The Jordan River basin: at the crossroads between conflict and cooperation
Several previous manuscripts have identified an opportunity to create a positivesum outcome for fresh water development and use by the five riparians of the Jordan River basin, in which all parties would receive enhanced resources concurrently, over time. This relies on the development of 'new water' coupled to the more efficient use of the existing water supplies. The application of the ...

Incorporation of the Multiple Barrier Approach in drinking water risk assessment tools
A number of existing risk assessment tools make reference to, or incorporate, a Multiple Barrier Approach to drinking water safety. Three waterborne disease outbreaks that occurred in developed nations were used as case studies to test a selected set of risk assessment tools. The outbreaks were used to determine how well the risk assessment tools identify hazards and vulnerabilities associated ...

Treatment and remediation methods for arsenic removal from the ground water
Globally, ground water is contaminating by arsenic continously, which needs economic treatment and remediation technologies. Physical, chemical and biological treatment methods have been developed, that include different kinds of filters, bucket type units, fill and draw, kalshi etc. The remediation methods discussed are air oxidation, reactive barriers, utilisation of deeper aquifers and ...

RO brine treatment and recovery by biological activated carbon and capacitive deionization process
The generation of brine solutions from dense membrane (reverse osmosis, RO or nanofiltration, NF) water reclamation systems has been increasing worldwide, and the lack of cost effective disposal options is becoming a critical water resources management issue. In Singapore, NEWater is the product of a multiple barrier water reclamation process from secondary treated domestic effluent using ...

Understanding drivers and barriers: the key to water use behaviour change
In southwest Victoria, like many other regions in Australia, drought, climate change and population growth have exposed gaps in water supply. To develop effective demand management strategies for rural and regional areas, this paper investigates the drivers and barriers to water saving in southwest Victoria. Although the majority of people felt water saving was important, the drivers for water ...

Full-scale KB-1® Bioaugmented Biobarrier for TCE Plume Containment
Problem DefinitionThe site is a former manufacturing facility, where a historic trichloroethene (TCE) release created a plume 1,100 feet wide and 7,000 feet long averaging 3,600 micrograms per liter (μg/ L) TCE, with a groundwater velocity of about 2 feet per day. Prior to biostimulation with electron donor, the groundwater conditions ranged from aerobic to mildly reducing and Gene-Trac DNA ...

On storm surges induced by the Bora wind in the Lagoon of Venice
It is well known that the hydrodynamics of the Venice Lagoon is strongly dependent upon both tides and prevalent wind regimes, namely the Sirocco and the local wind Bora. However, while the effect of the Sirocco on the sea level has been an subject of a large number of experimental and theoretical studies because of its dramatic impact on Venice, less attention has been paid to the effect on the ...

Permeable Adsorbing Barriers for groundwater remediation from hexavalent chrome pollution
Chrome ions removal from aqueous solutions by adsorption onto an activated carbon (Aquacarb 207EA by Sutcliffe Carbon) and a South African coal char is illustrated. Different chrome concentrations, pH and salinity levels are tested. Experimental data are interpreted by means of a Langmuir approach-based model. Results show that a Permeable Adsorbing Barrier (PAB) made of Aquacarb 207EA can ...

UAT - Leo J. Vander Lans Water Treatment Facility Uses UAT RO System to Treat Recycled Wastewater
Located along the Los Angeles and Orange County border in California, the Alamitos Barrier protects a portion of the Central Basin from seawater intrusion. Through the years, over-pumping of ground water basins has caused water levels to drop and seawater to enter the basins. To prevent additional contamination, seawater intrusion barriers using potable water to source injection wells were ...

Contaminated Groundwater Cleaned by Granular Carbon System
Untitled Document Summary: A granular activated carbon system developed by Calgon Corp., is being used to remove various toxic materials from contaminated groundwater at the U.S. Army's huge Rocky Mountain Arsenal near Denver, Colo. The pilot containment/treatment project, which went into full operation in late August, 1978, has been described as one of the ...
