  • Identifying water quality monitoring stations in a water supply system

    Despite good quality assurance and conformance to the standards at the treatment plants, water quality could vary considerably within the distribution network. As water flows through the pipe network, its quality undergoes various transformations due to many factors such as the properties of the finished water, pipe materials, water temperature, water age and low level of disinfectant residuals. ...

  • Managing water quality impacts from drought on drinking water supplies

    Droughts, which are difficult to predict, are a natural feature of the hydrology in most regions. Climate change, however, has the potential to increase the frequency and magnitude of future droughts. While the lack of water availability during droughts is widely publicized, there are equally severe water quality impacts that occur during and after droughts as well. Recent droughts have led to ...
