No pilot trial – no problem: data led remediation in fractured bedrock

This webinar presented a case study where a complex legacy hydrocarbon contamination challenge was addressed within fractured bedrock adjacent to sensitive surface water receptors.

Conventional remediation approaches were likely to be slow, inefficient, or pose environmental risk. Instead, a targeted, data‑led remediation strategy was adopted, combining in‑situ thermal remediation with multi‑phase extraction to address residual LNAPL within fracture networks to a reasonable and sustainable extent.

The speakers, Kasia Borthwick and Giles Lock, focused not on the technology alone, but on how it was applied: using detailed geological and contaminant data to identify discrete treatment zones, adapt extraction and heating horizons, and optimise system performance over time. The project demonstrates how intelligent interpretation of data, phased delivery, and multiple lines of evidence can improve remedial outcomes, reduce energy demand, minimise unnecessary intervention, and achieve regulatory acceptance.

The session highlighted practical lessons for applying remediation technologies proportionately, sustainably, and effectively on complex brownfield sites.
