Robert Ettinger and Mital Desai (California) will present at the California Land Recycling Conference (CALRC) at the Carson Community Center in Carson, California at 2:45 p.m. PST on June 21-22, 2022.

Robert will present "Mitigating Confusion on Vapor Intrusion: Empirical Attenuation Factor Sensitivity Analysis and Approaches to Improve Vapor Intrusion Screening at Redevelopment Sites." Mital will present "Going Green: Connecting Sustainability with Remediation Success."

Robert Ettinger is a Senior Principal Environmental Scientist based in California with more than 30 years of professional experience focused on soil vapor extraction system design, vapor emission estimation, and subsurface contaminant vapor migration to indoor air. Robbie has extensive experience in assessing potential subsurface vapor intrusion to indoor air associated with former and current gasoline retail and distribution, petroleum pipeline, and petrochemical manufacturing facilities. This experience includes managing human health risk assessments, designing and implementing groundwater and soil vapor remediation systems, leading negotiations with regulatory agencies on behalf of individual companies, and developing risk-based strategies for corporate environmental liability and business management initiatives.

Mital Desai is a Senior Professional based in California with more than 15 years of experience focused on environmental investigation; remediation system design, operation, monitoring, maintenance, and optimization; site closure; brownfield redevelopment; due diligence; and California Environmental Quality Act (CEQA) support. Throughout her career, Mital has successfully led multi-discipline, multi-year complex projects for a variety of clients and stakeholders including municipalities, private corporations, and has worked at the direction of in-house and outside legal counsel. For site remediation, she has experience in technologies such as low permeability slurry walls; soil vapor extraction; air sparge and biosparge; dual phase extraction; in situ treatments; excavation and confirmation sampling; vapor intrusion mitigation systems and light non-aqueous phase liquid (LNAPL) recovery.

Hosted by the Center for Creative Land Recycling (CCLR), U.S. EPA Region 9, and the California Department of Toxic Substances Control's (DTSC) Office of Brownfields, the California Land Recycling Conference is the premier event for professionals working on land reuse. Focusing on the timeliest issues both unique to California and resonating with the national big picture, the Conference is an innovative space for learning and connecting.

CCLR promotes the sustainable, equitable, and responsible reuse of underutilized and environmentally-impacted properties. They educate, advocate, assist, and convene stakeholders to revitalize communities through land recycling. Their mission is simple: drive responsible, equitable, and sustainable development on land that's already been used. By building on underutilized land, they preserve open space, reduce the environmental impact of their cities and towns, and create the kinds of vibrant neighborhoods where all want to live.

CCLR serves as U.S. EPA's Technical Assistance to Brownfield Communities (TAB) provider in Alaska, Arizona, California, Hawaii, Idaho, Nevada, Oregon, Washington, and the Pacific Island territories.

Presentation Information

Title: Mitigating Confusion on Vapor Intrusion: Empirical Attenuation Factor Sensitivity Analysis and Approaches to Improve Vapor Intrusion Screening at Redevelopment Sites
Presenter: Robert Ettinger
Copresenters: Rafat Abbasi/DTSC, Dan Gallagher/DTSC, CY Jeng/DTSC, Michelle King/EKI Environment and Water
Date/Time: Tuesday, June 21, 2:45 p.m. PST
Abstract:
During this panel, experts will reveal an approach highlighting multiple lines of evidence, proposed plans to revise the Johnson and Ettinger model, and revisions to HERO Note 4. Additionally, panelists will discuss the updated California database recently developed with sensitivity analysis and how attenuation factors, risk assessment, and the application of multiple lines of evidence can help guide investigation, data analysis, off-site sampling decisions, and development of an updated attenuation factor for vapor intrusion screening at redevelopment sites.

Title: Going Green: Connecting Sustainability with Remediation Success
Presenter: Mital Desai/Geosyntec
Copresenter: Luis Navarro/Langan
Date/Time: Wednesday, June 22, 1:00 p.m. PST
Abstract:
This panel will examine sustainable remediation both holistically and in the individual dimensions (economic, social, environmental) with practical take-aways for project management. Expert presenters will discuss case studies that illustrate ways of presenting the value case for sustainability, strategically highlight metrics, and share ideas for integrating sustainability into existing projects. Additionally, panelists will review how sustainability can impact clean-up design, 'green remediation' technologies such as phyto and bioremediation and provide an explanation of what sustainable remediation can mean from both an economic and community capability building perspective.
