Subsurface hydrocarbon remediation projects are often managed under significant uncertainty, particularly at excavation boundaries where decisions must balance cost, compliance and risk. Traditional laboratory‑based sampling provides high‑confidence data but is slow and spatially sparse, frequently leading to conservative excavation or costly under‑excavation and rework.

In this webinar, our speaker will present a practical evaluation of how rapid, field‑based total petroleum hydrocarbon (TPH) measurement using mid‑infrared (MIR) spectroscopy can improve excavation outcomes. Drawing on the RemScan rapid classification approach and recent Monte Carlo simulation studies, the session will examine how sampling density, vertical resolution and classification uncertainty influence remediation decision‑making.

In this webinar, our speaker will explore:

• How sampling density and vertical resolution affect excavation accuracy
• Where under‑excavation risk arises in conventional laboratory‑only workflows
• How rapid field measurements can be integrated into existing remediation practices
• The trade‑offs between investigation cost and remediation risk
• How real‑time data can support adaptive excavation decisions

The webinar will also consider alignment with current regulatory frameworks for contaminated land assessment and excavation validation, particularly in relation to TPH thresholds.

This webinar will be particularly valuable for environmental consultants, remediation contractors, regulators and project managers seeking practical ways to reduce uncertainty and deliver more efficient remediation projects. A live question‑and‑answer session will follow the presentation, and the webinar will be recorded.
