Persulfates have been successfully and safely applied at thousands of sites for over 20 years and represent one of the truly established remediation technologies with the power to treat most common contaminants of concern. In support of these continued efforts, Dr. Brant Smith will present fundamental characteristics and health and safety considerations regarding persulfate compounds and common activators. 

This will include recommended methods and standards for safe handling, storage, and application of these reagents. In addition, Dr. Smith will review historic health and safety issues that have occurred and provide recommendations on how avoid these situations in the future.

This webinar is part of a series on thoughts and best practices for application KLOZUR® persulfates including webinars on chemistry, design, application methods, and monitoring presented by either Brant Smith or Josephine Molin. Please join us for this live webinar followed by a Q&A session.

Dan Leigh will present on the recent market trend of adding ultra fine Zero Valent Iron (ZVI) into the subsurface in a variety of manners to help treat subsurface contamination. Combining ultra fine ZVI and organic reagents establishes a symbiotic relationship that directly degrades recalcitrant chlorinated compounds including solvents, pesticides and other compounds treated via the reductive pathway such as energetics. In addition to creating reductive conditions, ultra fine ZVI has several advantages over historic iron additives including ability to distribute in a wide variety of sediment types, and establishment and maintenance of groundwater conditions conducive to reductive treatment.  

Dan will emphasize how ultra fine ZVI can be cost effectively applied with other reagents including Evonik’s ELS® and GEOFORM® Soluble reagents to promote chemical, biological and biogeochemical reductive pathways in a single application.
