Paul NathanailPaul Nathanail
Professor of Engineering Geology, University of Nottingham, & Managing Director, Land Quality Management Ltd, UK

Prof Paul Nathanail's interest in sustainable remediation stems from a long track record in the broader field of sustainable urban land management. The concept is 'trending' and in danger of losing its impact through misuse on company websites and marketing literature.

The plethora of spreadsheets, programs and applets purporting to diagnose sustainable remediation are in danger of cloaking a simple concept with overly elaborate, time consuming and expensive procedures. The middle ground in achieving a step change in how we remediate is to use simple tools and approaches to help identify those remedies likely to deliver optimal net social, economic and environmental benefits.

Henry J. SchuverHenry J. Schuver
Environmental Scientist, US Environmental Protection Agency Headquarters, Office of Resource Conservation and Recovery, Washington, DC USA

Henry J. Schuver holds a Doctor of Public Health (DrPH) in Environmental Epidemiology from Johns Hopkins School of Public Health and a Master of Science in Geology from Arizona State University.

Schuver authored the national RCRA Corrective Action Environmental Indicator (EI) guidance for both Groundwater Migration and for Human Exposures in 1999. This was to help meet the Government Performance and Results Act (GPRA) of 1993. The Human Exposures EI guidance-forms required a review of all plausible exposure pathways from subsurface contamination including vapor impacts to indoor air. He subsequently led the development of the 2001 Supplemental Guidance for Vapor Intrusion (VI) for RCRA EI Determinations (at all High-Priority RCRA sites) which raised the awareness of VI exposures nationally and led to the development of the 2002 OSWER (RCRA & Superfund) draft VI guidance.

Since 1999, Schuver has been leading annual national workshops with national and international experts in VI to improve the scientific understanding of vapor intrusion and VI risk-management decision making. He is currently leading the development of a technical document on ‘Radon Lessons’ based on the scientific observations from decades of Radon intrusion studies. His life goal is to find cost-effective responses to VI risks/potential that benefit all stakeholders including public health and welfare, such as ‘Soil-Gas Safe Communities.’
