  • Tungsten groundwater contamination

    Originally thought to be non-toxic, tungsten is replacing lead in fishing weights and in ammunition for hunting and recreational shooting. However, recent studies indicate that (under certain environmental conditions) some forms of tungsten can move readily through soil and leach into groundwater. A Kansas State University scientist investigates. Tungsten is a naturally occurring metallic element ...

  • Treatment of abstracted groundwater

    Since abstracted groundwater can consist of a complex mixture of river bank filtrate and polder water, which have different origins and compositions, its treatment is challenging . An article in Drinking Water Engineering and Science discusses the effect of the properties of this mixture on the production of drinking water. In the Netherlands, over 60% of ...

  • Pesticides persist in groundwater, say SSSA

    Numerous studies over the past four decades have established that pesticides, which are typically applied at the land surface, can move downward through the unsaturated zone to reach the water table at detectable concentrations. The downward movement of pesticide degradation products, formed in situ, can also contribute to the contamination of ground water. Once in ground water, pesticides and ...
