early warning water contamination detection system Applications

  • Protecting of Drinking Water Infrastructure

    Water abstraction points may be affected by spills from farms or factories, and deliberate contamination. Early warning monitoring systems are required to alert operators to these contaminants and to changes in key water quality parameters. A timely response is necessary to prevent contamination and disruption of the public water supply.

    Chelsea Technologies Group has developed FastGuard to observe the natural trends in water quality parameters and rapidly detect and report anomalies.



    FastGuard is ideally suited for early detection of contamination events. It gives prompt reporting and asessment of the threat and has high sensitivity with minimal false alarm rate.

  • Airport Environmental Monitoring

    Water pollution from airport run-off is increasingly coming under public and government scrutiny. As environmental regulations tighten, the ability to monitor for aviation fuel contamination from runway run-off has become essential.

    Monitoring sites at airports can be extremely challenging often with no power or telephone lines available and with limited access for maintenance. Chelsea’s robust UviLux Hydrocarbon Sensor with its low power consumption and high accuracy is ideally suited for this application. Installed at various locations around the airport, deployed with it’s own integrated anti-biofouling system, utilising the GSM network, the monitoring sites send data to a secure ftp site, where any internet enabled device can access the data. In this way the systems act as any early warning system allowing any hydrocarbon discharge to be detected in real-time.

    Optional environmental monitoring features include remote control to allow the user to turn equipment on and off, change the sample rate and detection range. There is also a facility to allow SMS text and email alarm notifications triggered by user-defined set-points together with customised web pages, data displays and automated data downloads via an ftp server.

    Airport runoff can contain high concentrations of various pollutants, in particular polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), the environmental levels of which have to be monitored. An understanding of the magnitude of contamination due to airport runoff water is important for the effective management of airport infrastructure. Chelsea’s robust UviLux Hydrocarbon Sensor with its low power consumption and high accuracy is ideally suited to the airport environment.
