Non-Destructive UV-Optical Device in Clear Well Casing for Monitoring Geology, LNAPL Distribution, and Natural Source Zone Depletion (NSZD)
High-resolution site characterization (HRSC) tools provide detailed vertical profiles of subsurface contamination. Some tools also capture lithology data, which helps develop more complete conceptual site models (CSMs) for light non-aqueous phase liquids (LNAPL). However, HRSC surveys often occur only once due to the cost of large equipment and mobilization. Meanwhile, subsurface conditions change over time.…
In-Situ Remediation 101: Four Decades of Evolving Chemistries, Technologies & Applications
Presenter: John V. Fontana, CPG, CWD, Vista GeoScience Over the past 40 years, in-situ remediation has advanced from early experimental injections to a versatile suite of proven technologies. This one-hour presentation begins with a concise history of reagent chemistries and delivery methods, then moves into an overview of today’s state-of-the-art practices for optimizing injection strategies…
Vista Guest Webinar – Evolving the Playbook: Combining ISCO, Sorption, and Biodegradation for Petroleum Site Success
Presenter: Todd Herrington, Director of Product Management, REGENESIS Petroleum-impacted sites (e.g., UST and oil/gas facilities, etc.) often present complex remediation challenges due to residual mass, back diffusion, and fluctuating groundwater conditions. In addition, the path to closure for these sites has evolved and at times, requires integrated remediation strategies. While in situ chemical oxidation (ISCO)…
