Field Notes: Hydraulic Profiling Tool (HPT) in Action

Real-Time Subsurface Data for Smarter Environmental Monitoring Well Installation

Successful environmental monitoring begins with a detailed understanding of subsurface conditions. Before monitoring wells are installed, environmental consultants and drilling contractors need reliable data to identify groundwater-bearing zones, understand site geology, and optimise well placement.

Working alongside the team at Legion Drilling, we're deploying the Hydraulic Profiling Tool (HPT) to deliver real-time subsurface characterisation and high-resolution groundwater data.

As the probe advances through the ground, the HPT continuously measures formation pressure and hydraulic conductivity, helping identify perched groundwater zones, transmissive pathways, and deeper aquifers. Live data is streamed directly from the field, allowing project teams to make informed decisions immediately rather than waiting for laboratory results or post-drilling analysis.

Why Use HPT?

The Hydraulic Profiling Tool provides a rapid and cost-effective method for:

• Identifying groundwater-bearing formations

• Locating perched water tables

• Detecting transmissive sand and gravel layers

• Defining aquifer and aquitard boundaries

• Improving monitoring well placement accuracy

• Reducing investigation uncertainty

• Supporting environmental site investigations and remediation projects

By understanding the subsurface before drilling begins, teams can minimise unnecessary drilling, optimise well design, and improve overall project outcomes.

Environmental Site Investigation with Real-Time Results

Traditional investigation methods often rely on interpreting conditions after drilling has been completed. HPT testing provides immediate insight into changing subsurface conditions, enabling environmental professionals to adapt investigation strategies while still on site.

For contaminated land assessments, groundwater investigations, remediation projects, and hydrogeological studies, this real-time intelligence can significantly improve decision-making and reduce project risk.

Supporting Better Groundwater Monitoring Programs

Accurate groundwater monitoring wells start with accurate subsurface data. By combining Legion Drilling's field expertise with advanced direct push technology, project teams gain a clearer understanding of groundwater systems before installation begins.

Real-time subsurface intelligence. Better well placement. More informed environmental decisions.
