OUR EXPERTISE
« PROTECTING WATER RESOURCES IS OUR PASSION »
TRAQUA combines the development of innovative technology with expertise in hydrogeology to provide targeted solutions to problems related to (ground, surface, distribution, waste) water flows.
We implement tailor-made in-situ monitoring based on a preliminary analysis of the situation with high temporal and spatial resolution. Continuous sampling of data such as fluorescence, turbidity and water temperature provides useful information about your problem for detailed analysis, scientific diagnosis and resolution.
Hydraulic connectivity, flow and groundwater behaviour, vulnerability of water resources, water quality monitoring or even turbidity monitoring in the marine environment... these are just some of the applications for which TRAQUA can provide its technology and expertise.
IN-SITU DYE TRACING AND LONG TERM MONITORING
Dye tracing using non-toxic fluorescent tracers allows the identification and characterisation of water flow in various contexts: natural underground flows, urban drainage networks, infiltration, connectivity between water bodies, contamination, etc.
The use of STREAM® in-situ fluorometers allows a direct and precise measurement of the presence and concentration of our tracers, without the need for additional analysis. The use of our instruments greatly simplifies logistics and provides faster and more reliable results.
Due to the high sensitivity of these field fluorometers and the low detection limit of a few hundredths of a ppb (1ppb = 1 µg/litre), only a very small amount of tracer is required. The ability to use UV tracers limits the visual impact of dye tracing on sensitive sites.

In addition, the use of automated instruments greatly increases the temporal resolution of measurements (up to 1 measurement per minute) to provide extremely accurate and detailed data for analysing a problem.
Our strength lies in our ability to rapidly deploy a large monitoring network of autonomous and compact fluorometers. This makes it possible to respond quickly and accurately to a wide range of flow problems by monitoring natural parameters or using dye tracing tests.
