I presented our latest research on groundwater recharge yesterday to the NSW government water planners for groundwater and coastal syatems. And then led tours to show the team our recharge monitoring sites at Harrie Wood Cave, Yarrangobilly.

Proud winner of the Dewatering Consultant Project of the Year 2025 award by the 'The Dewatering Institute' for our hydrological study and tracer tests on the Brussels Metro3 project.

We provided in-depth data on groundwater movement for a ground freeze in complex, heterogeneous underground.

Our 𝗦𝗧𝗥𝗘𝗔𝗠 𝗳𝗹𝘂𝗼𝗿𝗼𝗺𝗲𝘁𝗲𝗿𝘀 🔦 can handle a tough job 💪

No external data loggers. No extra batteries. Just robust, self-contained devices, designed and assembled in-house.

Our fluorometers are compact, easy to install, and built for real-world conditions.

I love visiting London and taking the Channel Tunnel/Eurotunnel. I have always been struck by the incredible engineering that must have gone into constructing a tunnel 45 metres under the bottom of the sea that curves slightly up and down as it follows the Chalk Marl layer.

Case study 2 - risk assessment / catchment site delimitation for drinking water.

Absence of tracer recovery doesn't always mean the absence of a connection!

Man-made disasters and their long-lasting impact on 𝗴𝗿𝗼𝘂𝗻𝗱𝘄𝗮𝘁𝗲𝗿, human health and the environment.

Pollution is not the only disaster that can affect groundwater. Subsidence because of over-extraction is a worldwide phenomenon. Let's take a look at Beijing.
