Remediation of Soils Contaminated with Chlorinated Pesticides, Chlorinated Solvents, and Organic Explosive Compounds
This webinar will provide an overview of Evonik’s reagents for in situ and ex situ remediation of soils impacted with a chlorinated organic compounds and organic explosives. Dr. Seech will present an overview on the Daramend® family of reagents including details on their composition, associated advantages, treatment chemistry, and applicability to destruction of various soil contaminants. He will also provide results from completed projects where Daramend® has been used to economically remediate soils at industrial, agricultural, and military sites in Brazil, Canada, China, Colombia, El Salvador, Europe, and the United States. Among the chlorinated pesticides successfully treated are 2,4-D, 2,4,5-T, Aldrin, Heptachlor, Chlordane, Dieldrin, DDD, DDE, DDT, Lindane, Metolachlor, and Toxaphene. The organic explosive compounds successfully treated include TNT, DNT, amino-nitrotoluenes, RDX, HMX, Tetryl, and nitrocellulose. The full range of common chlorinated solvents including PCE, TCE, CT, and CF as well as their breakdown products have also been effectively treated. For applications where a reduction in leachability of the target compounds is required Daramend® Plus, which includes activated carbon, has proven to be effective. Performance data from several completed projects will be presented.

Dr. Brant Smith will review the technical fundamentals of KLOZUR® CR and several successful case studies. KLOZUR® CR, or combined remedy, is a blend of KLOZUR® SP and PermeOx® Ultra. This create the potential for three potential remediation pathways from a single application including hydrogen peroxide and alkaline activation of the KLOZUR® SP, aerobic bioremediation and possibly anaerobic oxidation using sulfate as the electron acceptor. The fundamental chemistry behind KLOZUR® CR will be discussed. |

Dr. Alan Seech presents an overview of our reagents for aerobic in situ and ex situ bioremediation of soils contaminated with a variety of compounds including PCP, PAHs, phthalates, and petroleum hydrocarbons. He will present the effectiveness of Terramend® products for diverse soil contaminants based on completed projects for the economic remediation of soils in wood preservation, chemical production, and hydrocarbon processing. |

In addition to the biological and geochemical processes, Dan Leigh describes in more detail how toxic metals are bound. Results of laboratory, pilot and large-scale field studies of sites where GeoForm® products have been used for the in-situ treatment of chlorinated organic matter and metals will be presented. We also provide information on innovative sampling and analysis methods. |

Drew Baird and Chapman Ross of FRx and Brant Smith of Evonik will present the use of controlled hydraulic fracturing for the placement of KLOZUR® KP slurry. The team shows the results of applying the product using solid suspensions to remediate a number of common contaminants. Practical experience underpins the results from the application of KLOZUR® KP. |

Design strategies and applications for combining in-situ chemical oxidation (ISCO) and in-situ stabilization and consolidation (ISS) are the topic of this webinar. You will get an overview of design strategies, bench testing, and field application considerations. |

|
Our soil remediation expert, Dr. Alan Seech, discusses how Daramend® Reagent controls soil chemistry to promote chemical and microbiological processes that enhance the anaerobic destruction of key organic explosive compounds as well as their degradation products. |
||
|
For more than two decades, biological (enhanced reductive dechlorination; ERD) and abiotic (in situ chemical reduction; ISCR) reduction processes have been used to degrade chlorinated volatile organic compounds (CVOCs) in situ. We will show you how chemical and biological treatment processes can be improved by GeoForm®. |

Dr. Smith discusses the key characteristics that differentiate subsurface treatment of 1,4-dioxane compared to many other common contaminants of concern. KLOZUR® is the product of choice when it comes to contamination by 1,4-dioxane which is the case at many sites. |
||
|
Our expert team explains how MetaFix® and EHC® Reagents work to remove soluble heavy metals with a focus on arsenic, chromium, lead, and mercury. |
||
|
Learn the basics of combining in-situ consolidation and stabilization with in-situ chemical oxidation. These proven technologies have recently been increasingly combined to achieve a variety of remediation goals in a single application. |
||
|
KLOZUR® KP is ideal for treating highly soluble contaminants in the aqueous phase, such as 1,4-dioxane, or for treating contaminants in low permeability soils that persist for extended periods of time. |
||
|
We are introducing KLOZUR® One, a fully soluble all-in-one product suitable for treating highly contaminated source areas or plumes. The product simplifies the application of KLOZUR® activated persulfate in the field, making it even easier. |

|
Dr. Brant Smith of Evonik, Professor Dan Cassidy of Western Michigan University, and Tom Simpkin and Mike Perlmutter of CH2M will present strategies using in situ mixing to apply alkaline activated persulfate. |
