  • High frequency monitoring needed to protect UK rivers - Case Study

    The science behind nutrient pollution in rivers is still poorly understood despite the fact that nitrate and phosphate concentrations in the UK’s rivers are mostly unacceptable, although an element of uncertainty exists about what an acceptable level actually is. Key to improving our understanding of the sources and impacts of nutrient pollution is high-resolution monitoring across a broad ...

  • Removal of perfluorooctanoic acid (PFOA) in groundwater by nanofiltration membrane

    Perfluorooctanoic acid (PFOA) is very persistent in the environment and resistant to typical degradation processes. PFOA has been widely used in surface-active agents and as an emulsifier in several products and can contaminate groundwater. Groundwater is considered as an important source of water; hence removal of PFOA contamination in groundwater is needed. This study aimed to examine the ...

  • Making Australian groundwater data accessible: the value of collaboration

    Access to nationally consistent information is essential to support informed decision-making about Australia's vital groundwater resources. However, until now it has been difficult to depict a seamless national picture of groundwater resources and frame groundwater issues at a national scale. This is because groundwater data is typically managed locally without consistent format or ...
