  • Biogeochemical Reductive Dechlorination (BiRD) Update: In-Situ Destructive Treatment of Recalcitrant Groundwater Contamination

    Jim Studer, Technical Consultant, InfraSUR LLC BiRD in situ chemical reduction is now a trusted method for treating difficult groundwater contamination. This approach uses both biotic and abiotic reactions. These reactions create ferrous monosulfides, which are very reactive and break down tough contaminants. BiRD works well on chlorinated solvents, but it also treats perchlorate, nitrate,…

  • HRSC 101 Update – Unravelling Complex LNAPL Sites with the Optical Image Profiling (OIP) Tools & Caution About False Positives

    Presented by John V. Fontana, CPG, CWD – Vista GeoScience High-resolution site characterization (HRSC) tools, when used properly, greatly improve LNAPL site investigations. This presentation focuses on the Optical Image Profiler (OIP), along with tools like the Membrane Interface Probe (MIP), Hydraulic Profiling Tool (HPT), and Electrical Conductivity (EC) sensor. Together, these tools provide detailed…

  • 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.…

  • 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)…
