Speaker Bio:

Mr. de Vlaming is a Principal Engineer and member of Geosyntec Consultants’ Guelph operations, offering 20 years of experience in process engineering design and project management. He has worked in a wide variety of settings, including impacted site remediation, mining, industrial chemicals, waste treatment, and food processing. His expertise covers the spectrum of unit operations and process equipment from storage tanks to complex control systems. This knowledge has been integrated into a wide array of client solutions to environmental and manufacturing problems. Mr. de Vlaming also specializes in managing project delivery services including detailed specification development, authoring procurement contracts for equipment and services, and managing tendering processes from expressions of interest through to final award. His role often includes overseeing project controls such as budgeting and budget management, maintaining critical path schedules, and earned value analysis for large design-build and design-bid-build projects.

Abstract:

Savron’s in situ smoldering using Self-sustaining Treatment for Active Remediation (STAR) is being applied as the primary source remedy at a former coal tar processing site located in Newark, NJ. Geosyntec is the at-risk project manager for the site owner, with Savron as the technology provider. The STAR technology relies on the contaminant to be the fuel source and with supplied air ignition is initiated. Once ignited the burn is propagated with the supplied air only and not more heat. The process can be sustained below the water table. This process has been deployed at a former coal tar processing site in Newark, New Jersey. Site contaminants include coal tars and cresols in both fill and native geological materials. The remedial objectives include treatment of free product to the extent practicable. STAR was selected as a cost-effective and non-invasive alternative to available remediation alternatives including ISCO, in-situ stabiliziation and conventional dig-and-haul. Two complete process trains, including air delivery, heaters, vapor extraction/treatment, and controls, are actively remediating the site currently and will continue to operate until anticipated completion in mid-2018. Approximately 2000 sequentially grouped ignition points are anticipated, covering 14 acres at depths ranging from 10 to 35 feet bgs. To date the project has successfully demonstrated in-situ treatment of heavy hydrocarbon free product, as observed in soil cores, analytical testing, and other indirect evaluation means, for a range of soil types, groundwater depths, and contamination profiles. This presentation will discuss key findings and progress of and evolutionary improvements to the technology since the remediation program was initiated.
