Dye tracing using harmless fluorescent tracers makes it possible to identify and characterize the water flow in various contexts: natural underground flows, urban drainage networks, infiltration, connectivity between water bodies, contamination, etc.
The use of in-situ STREAM® fluorometers allows a direct and precise measurement, without the requirement for additional analysis, of the presence and concentration of our tracers. The use of our instruments considerably facilitates logistics and provides faster and more reliable results.
Because of the high sensitivity of these field fluorometers and the low detection limit of a few hundredths ppb (1ppb = 1 µg/liter), only a very low amount of tracer is required. The possibility to use UV tracers limits the visual impact of dye tracing on sensitive sites.
