REMEDIATION SUPPORT SERVICES: Tracer TestingEffectively tracing the fate of agents in the subsurface.
IRSL staff have designed and implemented numerous tracer tests in both fractured and unconsolidated geologic materials.
We hold a Certificate of Approval in the Province of Ontario to inject a variety of tracers, providing our clients with a powerful tool in aiding the understanding of the distribution of contaminants and injected compounds.
- Sulphur hexafluoride
- And a wide variety of Stable Isotopes.
IRSL often uses natural and injected tracers to aid in the understanding of the fate and transport of contaminants within the subsurface, including the injection of reagents such as oxidants, reductants, and surfactants. Tracers can range from distilled water or salt water, sodium or potassium bromide, to dyes, etc., depending on the formation and objective of the tracer study.
Tracers are benign compounds, elements or solutions that are injected into the subsurface and then traced using sophisticated imaging techniques.
Tracer testing can be used to:
- Visualize groundwater flow patterns.
- Understand bedrock fracture zones.
- Monitor subsurface groundwater travel times.
- Confirm injection areas of influence in the subsurface.
