BlueLeg Monitor is a young innovative company focusing on surface water quality monitoring, in response to increasing concerns on the global aquatic environment and the lack of efficient, spatial and  fast monitoring technologies.


BlueLeg Monitor represents the commercial interests of Water Insight (Wageningen, The Netherlands) with whom we jointly or separately have several R&D projects under execution for clients such as :

  • the European Commission (incl. lead partner in FP7 projects),
  • Rijkswaterstaat (North Sea algae monitoring)
  • the World Bank (global projects),
  • the European Space Agency (feasibility studies in aquaculture and  cyanobacteria monitoring, modeling and forecasting)
  • several private companies (Mussel company Prins and Dingemanse


Water Insight, a spin-off of the Vrije Universiteit of Amsterdam in 2005 has developed a highly innovative water quality monitoring system for both sweet and salt water based on the combination of satellite information from various satellites for large surfaces, and in situ monitoring with the WISP, a handheld sensor ( or “mini satellite”)  that measures in real time and on the spot critical water quality parameters.


Both methods generate identical but complementary information. Satellites monitor large surface areas (typically in a range of tens of kilometers) and once a day, while the WISP monitors locally (typically in the range of meters) at any time during the day.


iQwtr: real time water quality mapping through citizen science

Recently we have added the iQwtr to our gamma of products.  The iQwtr™ is a smart device enabling you to measure your surface water quality on the spot by simply taking a picture of a water sample in the iQwtr container with your mobile phone, transferring it through our iQwtr™App and receiving feedback on the quality of the water in real time.  Real time mapping of the water quality on mobile internet applications provides swimmers and water users with the latest information. The information can be shared among swimmers via social media such as Twitter and Facebook, and provides Water Boards with a wide and real time early warning measuring network.

Real time environmental monitoring of surface water quality

The Water Insight Spectrometer (WISP) is an easy to operate handheld device that provides real time surface water quality information.

By taking an optical measurement, the WISP (within a minute) derives the following water quality indicators:

  • chlorophyll-a
  • phycocyanine (blue algae or cyanobacteria pigment)
  • CDOM (colored dissolved organic matter)
  • water transparency (Secchi)
  • total suspended matter


without the need for further laboratory analysis, presented in the display in real time and on-the-spot. Compared to laboratory measurements the WISP is fast, flexible and cost effective, and an indispensable tool in modern water management. The WISP means immediate and rich availability of information, ready for interpretation and action.


Applications of the WISP

The WISP monitor is a powerful decision support tool due to its speed, flexibility and instantaneous availability of data. Moreover the combination of similar and complementary satellite data and data interpretation through the dedicated web portal WISP-web is generating relevant information for :


  • aquaculture and shellfish production (incl. hazardous algal blooms, HAB)
  • dredging (turbidity monitoring in ecologically fragile areas)
  • water intake for desalination and industrial cooling water
  • environmental ecological status of lakes, rivers and coastal areas
  • swimming water safety (cyanobacteria are highly poisonous)


The WISP creates the possibility to immediately observe and analyze the effects of certain water system management decisions.

The WISP is using the same powerful algorithms that were developed b Water Insight for the interpretation of satellite data above large surface water areas. These satellite data however cannot be used reliably for scanning surface water quality near-shore and for inland smaller water bodies. Also for this reason the WISP has been developed. It is now possible to monitor surface water bodies with high accuracies, irrespective of the weather conditions and/or distortions in satellite data availability.

The data generated by the WISP can be read directly from a LED display at the device, are near real time and are automatically introduced into WISP-web, a website which is processing the observations and storing the data into the required format for reporting.

The WISP is increasingly being used by prestigious water management organizations worldwide, and is expected to become the market standard for instant water quality information.
