Case study: Demonstrating success with PlumeStop and colloidal ZVI – with Matt Burns of WSP
Recording Available| We are pleased to have guest speaker Matt Burns, Senior Fellow at WSP present this live, international webinar. He will present PlumeStop® and colloidal ZVI (cZVI) treatment case studies and practical analytical strategies used to demonstrate destructive treatment.
Stimulating biodegradation of chlorinated VOCs on activated carbon and direct abiotic treatment of using reduced metals such as ZVI are not new to the remediation industry and have proven to be highly effective when direct contact is made. However, the colloidal solid composition of these materials severely limits efficient in situ application at most sites.
The steric stabilization chemistry behind the Regenesis products PlumeStop and cZVI eases delivery challenges and dramatically widens the applicability window of these amendments to include most sites where in situ remediation is contemplated. These transformational amendments bring a unique set of regulatory and performance monitoring challenges when discerning desirable destructive processes from often unacceptable non-destructive mechanisms.

Caso di studio: Contenimento in situ di PFAS mediante PlumeStop Liquid Activated Carbon
First broadcast: May 22, 2018
Speakers: Marcello Carboni, Mediterranean District Manager
In questo webinar Marcello Carboni, Mediterranean District Manager di REGENESIS, discuterà della capacità del PlumeStop® Liquid Activated Carbon di trattare in modo vantaggioso i composti perfluorurati (PFAS), compresi PFOS e PFOA. Introdurrà le caratteristiche di questi contaminanti complessi, illustrerà come il PlumeStop adsorbe in situ i PFAS, discuterà le strategie di contenimento di plume di perfluorurati mediante barriere di iniezione, e presenterà un caso studio di un sito contaminato da PFAS in Canada che è stato bonificato con successo utilizzando il PlumeStop.
Questo sito, un ex stabilimento industriale di produzione di mobili in cui era presente anche una struttura di addestramento antincendio, era in corso di trattamento per la presenza residuale di idrocarburi petroliferi quando delle ulteriori analisi sulle acque sotterranee hanno indicato la presenza in falda anche di PFOA e PFOS. Utilizzando la metodologia direct push, il PlumeStop è stato iniettato insieme all’ORC Advanced® in 50 postazioni nell’acquifero in sabbia limosa al fine di trattare gli idrocarburi petroliferi.
Le analisi di monitoraggio post-iniezione su un arco temporale di 18 mesi hanno evidenziato che sia gli idrocarburi petroliferi che PFOA e PFOS sono scesi al di sotto dei limiti di rilevabilità strumentale. Sarà inoltre discusso un sito italiano contaminato da PFAS, dove sono attualmente in corso test batch e in colonna prima di procedere ad un’applicazione pilota in campo.

Case study: Successful in situ remediation of PFAS using PlumeStop – with Rick McGregor of ISRL
First broadcast: May 16, 2018
Speakers: Rick McGregor President, InSitu Remediation Services Ltd
Recording Available | In this webinar we are pleased to have as a special guest speaker Rick McGregor, President of InSitu Remediation Services Ltd. His presentation discusses the in situ remediation of PFOA and PFOS at a site in eastern Canada using PlumeStop® Liquid Activated Carbon™.
This site, a former industrial furniture manufacturing site where a fire training facility was co-located, was being remediated for residue petroleum hydrocarbons when groundwater testing indicated that PFOA and PFOS was present within the groundwater. Using direct push technology, Liquid Activated Carbon along with ORC Advanced® was injected at 50 locations within the silty sand aquifer to address the petroleum hydrocarbons. Post-injection testing over a one-year period indicated that the petroleum hydrocarbons along with the PFOA and PFOS was attenuated to below the applicable method detection limits.

Visualization and Modeling Tools for Evaluating Remediation Performance
First broadcast: October 26, 2017
Speakers: Grant Carey, Ph.D. President, Porewater Solutions and Maureen Dooley Director of Strategic Projects, REGENESIS
In this webinar we are pleased to have as a special guest speaker Grant Carey, Ph.D., President of Porewater Solutions. His presentation will demonstrate visualization and modeling tools which may be used to improve the assessment and communication of site remediation activities. Dr. Carey’s presentation will cover the following visualization and modeling tools:
- Visual Bio™ – A free radial diagram tool with unique modifications that now make it easy to visualize where biodegradation is occurring in groundwater. This visualization tool is well suited for evaluating contaminant and redox indicator trends during natural and enhanced attenuation. The methods and benefits of this approach are illustrated for a data-rich site where enhanced bioremediation was successfully implemented.
- ISR-MT3DMS™ – A reactive transport model which was recently updated to simulate the performance of PlumeStop® Liquid Activated Carbon™. Key features required to model the performance and longevity of PlumeStop are demonstrated for a case study application. The benefits of reactive transport modeling for designing a site remedy are also discussed.
Dr. Carey will be joined by Maureen Dooley, Director of Strategic Projects at REGENESIS, who will share her expertise on remediation of complex sites as it relates to the projects and modeling tools featured in Dr. Carey’s presentation.
