  • Drinking Water Standards

    The most important point of departure for drinking water standards is the World Health Organisation Guidelines for Drinking Water Quality. These are widely used throughout the world with the exception of parts of North America. WHO’s Guidelines have evolved over a period of 50 years from standards to guidelines, reflecting the fact that they have no legal force. The WHO emphasises that it ...

  • Ultrapure Water - The Standard for Resistivity Measurements of Ultrapure Water

    Abstract For years, resistivity, conductivity^ instrumentation has been used as a reliable indicator of ionic water quality, especially for ultrapure water (UPW). Traditionally, the instrumentation is procured, installed, powered up, and perhaps connected to a PLC, strip chart recorder, or a LAN. After that, the instrument and sensor receive no attention until a problem arises. Today, ...

  • Emission standards versus immission standards for assessing the impact of urban drainage on ephemeral receiving water bodies

    In the past, emission standard indicators have been adopted by environmental regulation authorities in order to preserve the quality of a receiving water body. Such indicators are based on the frequency or magnitude of a polluted discharge that may be continuous or intermittent. In order to properly maintain the quality of receiving waters, the Water Framework Directive, following the basic ideas ...
