Unpacking the Legacy, Challenges and Prospects around Creosote | GeoEnviroPro

🌍 In today's episode, we unravel the mysteries of Creosote contamination, exploring its historical impact and modern-day challenges. 🕵️‍♀️🔍

📋 Topics covered:

The history of Creosote use: From medieval woodstake churches to industrial applications in the 1800s.
Understanding Creosote's composition: Over 250 compounds, naphthalene's role, and its toxicity.
Unique challenges posed by Creosote: Persistence, unpredictable migration pathways, and more.

🌏 Sites under the spotlight:

Bow River Case: Extensive migration, containment measures, and a Greyhound bus station.
Oak Street Site: Remediation strategies, hydraulic containment, and cap-and-contain approaches.
Braid Street: UBC's natural attenuation research at the groundwater-river water transition zone.
Canadian White Pine Site: Remediation efforts and ongoing research with cron samplers.

💡 Management techniques explored:
Halo zones around Creosote piles.
Groundwater plume profiling with Waterloo Profiler.
UV-induced fluorescence for detection.
Sonic drill rigs for subsurface sampling.
Permeable cap installation at Oak Street.
Toxicity reference values (TRVs) and their importance.

🔍 Challenges and future prospects:
Geophysical techniques limitations.
Importance of representative groundwater sampling.
Low flow techniques for minimizing colloidal contamination.
Investigating other contaminants alongside Creosote.
