How Viruses And Bacteria Can Reach Drinking Water Wells
Scientists in Berlin and Milan study transport of microorganisms in bank filtration
Induced bank filtration is a key and well-established approach to provide drinking water supply to populated areas located along rivers or lakes and with limited access to groundwater resources. It is employed in several countries worldwide, with notable examples in Europe, the United States, and parts of Africa. Contamination of surface waters poses a serious threat to attaining drinking water standards. In this context, human pathogenic microorganisms such as some viruses and bacteria, originating from the discharge of wastewater treatment plants, form a major contaminant group. A detailed study at an induced bank filtration site along the Rhine river in Germany has now linked transport of bacteria to seasonal dynamics. Key results of the study show that floods should be considered as particular threats, because they can reduce the purificati
Humanity’s challenge of the century: Conserving Earth’s freshwater systems
by Saul Elbein on 10 May 2021
Many dryland cities like Los Angeles, Cairo and Tehran have already outstripped natural water recharge, but are expected to continue growing, resulting in a deepening arid urban water crisis.
According to NASA’s GRACE mission, 19 key freshwater basins, including several in the U.S., are being unsustainably depleted, with some near collapse; much of the water is used indiscriminately by industrial agribusiness.
Many desert cities, including Tripoli, Phoenix and Los Angeles, are sustained by water brought from other basins by hydro megaprojects that are aging and susceptible to collapse, while the desalination plants that water Persian Gulf cities come at a high economic cost with serious salt pollution.
