SUMMARY:Vista Guest Webinar - Evolving the Playbook: Combining ISCO\, Sorption\, and Biodegradation for Petroleum Site Success
DESCRIPTION:Presenter: Todd Herrington\, Director of Product Management\, REGENESIS \nPetroleum-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) remains a powerful tool for rapid mass reduction\, it’s increasingly clear that long-term remediation success may also depends on effective sorption and enhanced biodegradation. In this webinar\, Regenesis will outline a field-proven strategy that integrates\, as needed\, oxidation\, sorption\, or biostimulation-based treatment that is tailored to meet cleanup goals at complex petroleum sites. Drawing on years of collaboration with Vista GeoScience and other consulting firms\, we’ll demonstrate how products like RegenOx®\, PersulfOx®\, PetroFix® and ORC Advanced® are used in combination to deliver consistent performance\, mitigate rebound\, and accelerate regulatory closure. We’ll also explore how PetroFix\, a colloidal activated carbon\, is emerging as a leading treatment for both polishing and primary remediation. By combining immediate adsorption with sustained biodegradation support and enabling visual confirmation of distribution via its dark color\, PetroFix enhances both treatment confidence and long-term results. \nKey Takeaways:\n• Why sorption and biodegradation are essential mechanisms for achieving closure at petroleum sites—not just secondary steps\n• How to integrate ISCO (RegenOx\, PersulfOx) with electron acceptors (ORC Advanced) and colloidal carbon (PetroFix)\n• When to use PetroFix as a standalone remedy versus a follow-up to oxidation\n• Real-world lessons from OPS and private sites in collaboration with Vista GeoScience\n• Practical methods to validate injection success using PetroFix’s visual presence in groundwater or soil cores

SUMMARY:In-Situ Remediation 101: Four Decades of Evolving Chemistries\, Technologies & Applications
DESCRIPTION:Presenter:  John V. Fontana\, CPG\, CWD\, Vista GeoScience \nOver 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 and remediation performance. \nKey treatment targets—petroleum hydrocarbons\, chlorinated solvents\, dissolved metals\, and emerging contaminants such as PFAS—will be addressed. Attendees will learn about the full spectrum of available reagents\, including oxidants\, reductants\, biological amendments\, and sorption-based remedies\, and how integrated approaches can be combined for maximum impact. The session will also highlight essential elements of the recently released ITRC guidance\, with emphasis on the benefits of remedial design characterization (RDC) and on matching delivery technologies to site-specific challenges like low-permeability soils and fractured bedrock. \nFinally\, the presentation will reflect on lessons learned from early applications—why some strategies fell short—and how advances in chemistry\, design\, and injection technology now lead to greater success. In the end\, remediation remains a “contact sport\,” where success comes from the right tools\, a sound strategy\, and precise execution.

SUMMARY:Non-Destructive UV-Optical Device in Clear Well Casing for Monitoring Geology\, LNAPL Distribution\, and Natural Source Zone Depletion (NSZD)
DESCRIPTION: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. Groundwater levels shift\, and soil saturations vary. As a result\, contaminant distributions evolve in ways that one-time surveys can’t track. To meet this challenge\, E-Flux developed a tool that allows repeat vertical surveys at high temporal resolution\, adding a critical time-based dimension to traditional HRSC. \nThis UV-optical monitoring tool installs inside a solid\, dry well casing that includes clear sections for imaging. Once in place\, a device shines UV and visible light into the surrounding formation. This light reveals pore-scale features such as LNAPL presence\, distribution\, and soil structure. The system creates detailed vertical digital images\, which reflect current soil conditions and contaminant patterns. Additionally\, it captures visible changes over time in LNAPL saturation and soil water content. This capability makes it easier to track natural source zone depletion (NSZD) processes and changes related to site hydrogeology. \nThe presentation will also explain how the technology compares to standard well-based methods. E-Flux will share lessons learned about how groundwater fluctuations and soil types affect LNAPL redistribution. Presenters will include both lab and field data\, offering practical insights into when and where the tool performs best. Two field studies will demonstrate how UV-optical imaging complements or improves upon traditional LNAPL monitoring approaches. By the end\, attendees will understand how to apply this new monitoring method to support ongoing remediation\, improve site models\, and better measure NSZD activity over time. \nregister HERE
