Legion Drilling was proud to support the ACLCA NSW Drilling Workshop for Early Career Professionals, providing environmental consultants with the opportunity to gain practical, hands-on exposure to environmental drilling, site investigation techniques, and groundwater monitoring methodologies.
As environmental investigations become increasingly complex, understanding how drilling methods influence sample quality, data reliability, and project outcomes is more important than ever. The workshop was designed to bridge the gap between theory and field application, helping consultants better understand the practical realities of environmental drilling operations.
Getting Up Close with Environmental Drilling Techniques
Throughout the workshop, attendees observed a range of environmental drilling and sampling methods commonly used across contaminated land investigations, groundwater monitoring programs, and environmental site assessments.
Participants were introduced to:
Geoprobe drilling and direct push sampling
Vapour pin installation
Soil and groundwater sampling techniques
Well construction and development procedures
Site investigation best practices
These field demonstrations provided valuable insights into how drilling methodology selection can influence sample integrity, project efficiency, and the quality of environmental data collected on site.
Why Sample Quality Matters
One of the key topics discussed throughout the day was the importance of obtaining high-quality, representative samples during environmental investigations.
Environmental consultants rely on soil and groundwater data to make critical decisions regarding contamination assessment, risk management, remediation planning, and regulatory compliance. Poor sample quality or excessive sample disturbance can significantly affect the reliability of investigation results.
Legion's team demonstrated how drilling method selection, sampling procedures, and experienced field execution all contribute to achieving accurate and defensible environmental data.
Monitoring Well Installation and Groundwater Investigations
Attendees also gained practical insight into monitoring well installation techniques and groundwater monitoring best practices.
Topics included:
Bore construction fundamentals
Sand pack placement
Bentonite sealing
Well development procedures
Groundwater monitoring requirements
Common installation challenges and solutions
Understanding these processes helps consultants appreciate how monitoring well design and installation quality can directly influence long-term groundwater monitoring results.
The Importance of Consultant and Driller Collaboration
A recurring theme throughout the workshop was the importance of strong communication between environmental consultants and drilling contractors.
Successful environmental investigations rely on more than equipment and methodology. Clear communication during project planning, mobilisation, drilling operations, and reporting helps ensure that project objectives are understood and that the most appropriate drilling and sampling techniques are selected.
When consultants and drillers work together from the outset, projects typically benefit from:
Improved sample quality
Greater operational efficiency
Reduced project risk
Better investigation outcomes
More reliable environmental data
Supporting the Next Generation of Environmental Professionals
At Legion Drilling, we believe practical field experience plays a critical role in developing the next generation of environmental consultants.
Workshops like these provide early career professionals with the opportunity to see environmental drilling techniques in action, ask questions of experienced drillers, and gain a deeper understanding of how field practices influence investigation outcomes.
A special thank you to Orica for providing the site and supporting this valuable industry training opportunity, and to ACLCA for their continued commitment to professional development within the contaminated land and environmental consulting sectors.
