That’s the magic, and the challenge, of fluorescent dye tracing 🧪.

What looks like a mess to some is actually a treasure of data on hidden flows, connections, and the hydrogeological secrets beneath our feet.

Our 𝗰𝗼𝗺𝗽𝗮𝗰𝘁 𝗦𝗧𝗥𝗘𝗔𝗠 𝗳𝗹𝘂𝗼𝗿𝗼𝗺𝗲𝘁𝗲𝗿𝘀 (www.traqua.be/en/technologie), with a depth rating of -1000m, are up to the task of such challenging tracer tests. However, personally, I wouldn't dare to stare into the abyss 😅😱.

One of the tracers was injected in the Moskovskaja Cave, at an incredible depth of -970 metres.

These tests provided a completely new perspective on the hydrogeology of the Arabika Massif.

Speleological explorations and tracer tests performed in the 1980s by a team led by Alexander Klimchouk revealed a connection between the cave system and submarine springs in the Black Sea. These springs are sometimes located at 13–16 km from the injection points, at a depth of 200m below sea level.

TRAQUA conducted a tracer test near a road where a sinkhole had swallowed a small stream, accelerating erosion and increasing the risk of further damage. Through tracer testing, we assessed groundwater movement, the fate of the stream, and the impact of nearby industrial pumping.

Hidden cavities can collapse, disrupting transportation networks and swallowing cars and buildings. Remember the Corvettes swallowed by a sinkhole?

The dates haven't been decided yet, but most probably 3x3h online training, spread over 3 weeks, at the beginning of Summer (June-July). We'll keep people informed via our Newsletter, to which you can register via our website (bottom of homepage) : www.traqua.be Topic will be specific on dye tracing
