Speaker: Paul Gruca
Flexible Low-Volume, Continuous Oxidant Injections for Low Permeability and Logistically Challenged Environments
In-Situ Chemical Oxidation (ISCO) injections, and specifically the use of permanganates, have been a successful and widely accepted remedy to address contamination within the environment. However, limiting conditions at some sites complicate the implementation of ISCO injections such as low-permeability geologies, excessive rebound/desorption, preferential pathways to the surface or receptors, recalcitrant areas, logistical issues, and fractured bedrock, among others. As a result, ISCO and/or the use of sodium permanganate are excluded from consideration.
Weaver Consultants Group’s Remediation Services has been providing turn-key remedial solutions from design to construction through operation, maintenance, and monitoring for numerous client types. To uniquely support their clients’ site-specific needs, Weaver Consultants Group pioneered an automated, continuous low-volume application technology to utilize various types of amendments in these troublesome conditions and expand the possibility of ISCO permanganate remedies to these sites. Their proprietary “Low-Volume Continuous Oxidant Injection” (LVCOI) system has evolved and optimized during each generation and proven successful in distributing amendments while reducing or mitigating rebound within these challenging environments. This presentation will discuss the LVCOI concept and technology, its efficacy and success, evolution and optimization, and the opportunities these systems offer for the remediation of contaminated sites.
Paul Gruca, CWP is an integral member of Weaver Consultants’ Remediation Services team and certified industrial wastewater treatment operator, with 15 years of experience in environmental engineering and consulting. Weaver’s Remediation Services provides turnkey solutions for environmental liabilities, from design through self-implementation, with a focus on efficiency, optimization, and innovative approaches to accelerate remedial timelines and reduce overall project costs. They have successfully implemented their remedial strategies and obtained closure on over 150+ sites across the country on behalf of the DoD and their contractors, municipalities, insurance carriers, and large and small corporate clients. The Remediation Services team is currently implementing a number of in-situ soil and groundwater remediation programs for comingled and chlorinated solvent plumes, utilizing a variety of remedial technologies such as soil vapor extraction / air sparge (SVE/AS), sub-slab depressurization (SSD), enhanced reductive dechlorination (ERD), in-situ chemical oxidation (ISCO), in-situ chemical reduction (ISCR), and carbon-based trap and treat through numerous application techniques, as well as pump and treat systems and permeability enhancement through hydraulic and explosive fracturing.
Paul serves as a Senior Project Manager for Weaver’s Remediation Services, conducting and managing a wide variety of environmental and construction projects at petroleum and hazardous substance contaminated sites. He joined Remediation Services in 2019, along with his consulting and remediation experience from Weaver’s Chicago office. Paul has considerable experience in a wide variety of environmental focuses and has navigated projects through the regulatory environments of 14 states in the Midwest, west, northeast, and deep south on behalf of private and public corporate clients, Fortune 500 companies, municipalities, and DoD entities.
