Drilling-Based Sampling Methods That Ensure Sample Integrity
Sampling methods define how subsurface materials are collected during drilling activities. We apply established soil, groundwater, and rock sampling approaches to support environmental and geotechnical investigations, focusing on controlled collection, representativeness, and adherence to applicable project and regulatory requirements.
Sampling Methods
How Sampling Is Performed
Sampling during drilling involves collecting soil, groundwater, or rock materials using tools and procedures appropriate to subsurface conditions and project objectives. Methods are selected based on material type, depth, required sample quality, and disturbance tolerance. Sampling may occur during borehole advancement or after drilling is complete, using dedicated tooling to isolate target intervals. Proper handling, containment, and documentation are integral to preserving sample integrity and supporting laboratory analysis. Sampling activities are executed independently from interpretation, ensuring collected data reflects field conditions without analytical bias.

Sampling Methods FAQs
Learn more about drilling-based sampling methods, including how samples are collected, handled, and selected to support environmental and geotechnical investigations.
Sampling provides physical material from the subsurface for laboratory testing and evaluation, supporting characterization of soil, groundwater, or rock conditions relevant to environmental and geotechnical objectives.
Methods are selected based on material type, depth, subsurface conditions, required sample quality, and project or regulatory requirements, independent of interpretation or analytical conclusions.
Sampling may occur during drilling advancement or after borehole completion, depending on the material being sampled and the level of isolation or control required at the target interval.
Sample integrity is maintained through appropriate tooling, controlled collection procedures, proper containment, documentation, and handling protocols designed to minimize disturbance and cross-contamination.
Sample With Precision
Drilling-based sampling enables controlled access to subsurface materials at depth. Field-executed methods support accurate collection of soil, groundwater, and rock samples with clear documentation to inform investigation, monitoring, and planning decisions.
