Upcoming Webinars

Evolution of Two Remediation Technologies: ISCO + ISS 

📅 Wednesday, December 10, 2025
⏰ 12:00–2:00 PM ET
💻 Free for all to attend
🎓 2 PDH Certificates for EnviroClass Members!
🎙️ Hosted by Travis Bowman, EnviroWorkshops President

About the Webinar

Over the past two decades, In Situ Chemical Oxidation (ISCO) and In Situ Solidification/Stabilization (ISS) have each proven to be highly effective for treating contaminated soil and groundwater. Recent advancements now show that combining these two technologies can achieve even greater remediation performance, efficiency, and long-term stability.

In this live EnviroClass webinar, Dr. Brant Smith (Evonik) and Bill Lang (Lang Tool Co.) will bridge the gap between theory and practice.

  • Dr. Smith will explain the science behind ISCO and ISS mechanisms, the chemistry driving contaminant destruction, and how lab-scale data supports full-scale design.
  • Bill Lang will share contractor insights and field applications, highlighting how soil mixing and equipment innovations have made hybrid ISCO/ISS remedies more predictable, faster, and cost-effective.

Attendees will gain a clear understanding of how these complementary technologies continue to evolve—and how to apply them for successful site cleanup.

What You’ll Learn

✅ The principles and mechanisms of ISCO and ISS treatment processes
✅ Advantages and limitations of each technology—and when to combine them
✅ How laboratory treatability studies inform field-scale design
✅ Practical field insights, equipment advancements, and mixing techniques for ISCO/ISS applications
✅ Case studies demonstrating real-world results, lessons learned, and performance validation
