  • Managed aquifer recharge: rediscovering nature as a leading edge technology

    Use of Managed Aquifer Recharge (MAR) has rapidly increased in Australia, USA, and Europe in recent years as an efficient means of recycling stormwater or treated sewage effluent for non-potable and indirect potable reuse in urban and rural areas. Yet aquifers have been relied on knowingly for water storage and unwittingly for water treatment for millennia. Hence if ‘leading edge’ is defined as ...

  • Impact of over-pumping and sea level rise on seawater intrusion in Gaza aquifer (Palestine)

    Seawater intrusion is considered as one of the main processes that degrade water quality by raising salinity to levels exceeding acceptable drinking water standards. Over-abstraction is the main cause of seawater intrusion. Moreover, climate change and sea level rise speed up seawater intrusion. This paper presents the development of a coupled transient finite element model for simulation of ...

  • Who used your water yesterday?

    The answer to the question above boils down to numbers in the final analysis. With more than half of the world's population already based in urban areas the additional demand for core services such as water is overtaxing capacities for water supply and disposal in many of the world's larger cities. And the problem is only going to get worse. The proportion of the world's population that will be ...

  • Bottled versus tap water fact sheet

    Where does bottled water come from? Those beautiful mountain illustrations on water bottles are often very far from the true source of the water inside. Bottled water sources can be hard to track down, as bottled water manufacturers are not required to disclose where the water comes from or for that matter, what’s in their water. In fact, the best indicator of what kind of water ...

  • Microbiological assessment of private groundwater-derived potable water supplies in the Mid-West Region of Ireland

    Determining the likelihood that groundwater contains faecal coliforms can aid water resource management in facilitating the protection of drinking water supplies. This study assesses the incidence of the faecal indicator organism Escherichia coli in 125 private water supplies (PWSs) serving individual houses in the Mid-West Region of Ireland. Two factors, aquifer type and rainfall (mm), were ...
