  • Water Quality Monitoring for the “Big Four Parameters”

    Many different parameters can be measured in natural and artificial waters with sensors or via lab analysis. Each parameter effects water quality and the organisms that depend on the water for survival. Different states, monitoring agencies, and companies also place an emphasis on different water quality parameters to be monitored, depending on local conditions and mandates. For most water ...

  • Case study - Water quality in the Mississippi Basin

    A resilient method for monitoring water quality and nitrate levels in the harsh aquatic environment of the Mississippi River, in section 16, was required by the University of Iowa -IIHR. The monitoring of continually accurate water quality data was important for analysis, in conjunction with the diurnal mussel study of the University of Iowa. Monitoring water over extended periods of time in ...

  • Water Quality Monitoring and Testing Using an Environmental Logger

    Intelligent dataTaker System from CAS DataLoggers Water disruptions typically occur after a large amount of water has rapidly collected in a catchment area. As a result this water is subject to continual monitoring and testing for a variety of chemical and biological agents as well as clarity, rate of movement, and water levels for environmental management. Turbidity, conductivity, ...

  • Water quality is key to the success of Cardiff Bay

    Water quality has been a central theme in a redevelopment project that began with the creation of the Cardiff Bay Development Corporation in April 1987. This article will examine the role that water quality has played in the remarkable transformation that has taken place in Cardiff and explain how monitoring technology has developed to the stage whereby any person, anywhere in the world, can view ...

  • Dynamic soft sensors for detecting factors affecting turbidity in drinking water

    Effective monitoring of water quality is critical for water safety. In particular, online monitoring based on modeling is useful in several applications such as process assessment, hazardous event detection or common fault diagnostics in the water processes. Soft sensors have lately established themselves as a good alternative for different tasks of process control such as the acquisition of ...

  • Case study - Remote water quality monitoring in South Africa

    Situated in the Mpumalanga province of South Africa, the Xstrata Coal South Africa (XCSA) runs several open cut and underground mining operations producing thermal coal. To ensure their mining operations do not affect the surrounding natural water bodies, the company employs Hydrolab and OTT water quality monitoring equipment with remote data transmission options: the OTT ecoLog 800 water level ...

  • Why is Calibration of Water Quality Testing Equipment so Important?

    The calibration of water quality testing equipment is as important as the tuning of a musical instrument. When people find out I’m a chemist, the first thing they ask me is, “Are you Walter White?” (This shows you the kind of people I typically run into). The second thing they ask me is, “Why is calibration so important?” Simply stated, calibration is how we adjust ...
