Geosyntec Staff Featured at the 34th Annual International Conference on Soils, Sediments, Water and Energy

Geosyntec will make a substantial technical contribution at the Association for Environmental Health and Sciences Foundation (AHES) Foundation's 34th Annual International Conference on Soils, Sediments, Water and Energy at the University of Massachusetts in Amherst, Massachusetts on October 12-18, 2018.

Geosyntec-led contributions include a workshop, three platform sessions, three poster presentations. Jessica Yeager, P.E., LSP (Massachusetts) served on the Scientific Advisory Board.

The Annual Conference on Soils, Sediments, Water and Energy at the University of Massachusetts at Amherst has become the preeminent national conference in this important environmental area. The conference attracts 600-800 attendees annually which includes a wide variety of representation from state and federal agencies, military, industry (including railroad, petroleum, transportation, and utilities), environmental engineering, environmental consulting, and academia.

The Association for Environmental Health and Sciences Foundation, Inc. is a non-profit, member-supported, professional organization. Their purpose is to facilitate communication and foster cooperation among professionals concerned with the challenge of soil, sediment, and water assessment, cleanup, and protection.

With nearly two decades of relationship building and service, they know that resolutions for environmental contamination can be found only through the integration of scientific and technological discovery, social and political judgment, and hands-on practice. AEHS Foundation facilitates conferences, seminars, publications, collaborative partnerships, and their members-only online community.

Geosyntec's Contributions

Scientific Advisory Board

Delegate: Jessica Yeager, Geosyntec Consultants, Brookline, MA
Board Description: The AEHS Foundation attributes the success of this conference, in large part, to a very dedicated and hardworking Scientific Advisory Board (SAB). The SAB evaluates abstract submissions, recommends invited papers and presenters, advises with regard to session topics, and serves as conference ambassadors. The SAB is crucial to the conference development. Care is taken to create a board that represents philosophical, scientific, regulatory, and geographical balance.

Workshops

Title: Workshop 2 Tools for Evaluating Sustainability at Tier 2 Sites
Time: 1:00 p.m. – 5:00 p.m.,
Location: Room 169
Instructors: Anne Fitzpatrick, LHG, Geosyntec Consultants, Seattle, WA and Amanda McNally, P.E., Geosyntec Consultants, Pittsburgh, PA
Description: A set of "Tier 2" tools have been adapted from those developed for the Portland Harbor Superfund Site Sustainability Project to evaluate sustainability of remedial actions at smaller, less complex or data-rich sediment sites. These tools address the environmental, economic, and social impacts of remediation, while linking metrics to both regulatory decision criteria and stakeholder values. Our goal is to make the Tier 2 tools flexible and adaptable to different regulatory frameworks and stakeholder dynamics. After a review of principles underlying sustainable remediation approaches, workshop participants will engage in a detailed demonstration and evaluation of the tools, including the required inputs, mapping of metrics to both regulatory criteria and stakeholder values, calculation methodologies, and the numerical and graphical outputs generated. This approach will allow a broad-based group of stakeholders to be transparently engaged in the decision-making process, thereby resulting in more sustainable remedies with broader regulatory and public support.

Title: Workshop 5 Tracers and Surrogates (ITS) for Chlorinated Vapor Intrusion (CVI): Pursuing Additional Observations
Time: 8:30 a.m. – 12:00 p.m.,
Location: Room 164
Coauthor: Jeff Kurtz, Geosyntec Consultants, Greenwood Village, CO
Description: Three supplemental measures of CVI-related phenomena, referred to here as ITS, specifically temperature, pressure, and radon, have shown some promise for being readily implementable tools for improving the effectiveness and efficiency of CVI assessments and long-term monitoring. These measurements and observations were presented in AEHS Foundation's West Coast Conference (slides and audio recordings available at https://iavi.rti.org/WorkshopsAndConferences.cfm) and subjected to additional analyses. In summary, there is some evidence for reducing the number of indoor air samples needed to be statistically confident of representing the upper 95th percentile (e.g., Reasonable Maximum Exposure) conditions from 58 randomly timed samples to as few as three ITS-guided samples. Additional analyses for representing lower risk-based levels of concern (e.g., 0.48 ug/m3 TCE) showed that 95% confidence was possible with as few as two temperature-guided samples and one radon-guided sample. To further validate these ITSs in other buildings and settings, plans are 1) to further statistically test existing data sets and 2) to collect new ITS measurements during ongoing VI investigations. Where there is some evidence of a 'complete' CVI pathway, supplemental ITS measures taken concurrently along with indoor CVOC samples could provide additional evidence to illustrate the associations with ITS and provide an improved understanding of the value of the CVOC samples collected. For example, the evidence available so far indicates there is ~95% confidence in 'low' (non-RME) CVOC results being found when any of the three ITS were found to be 'low.' Thus, CVOC samples showing 'low' concentrations collected at times when the ITS values indicate a 'low' potential for VI would not be as meaningful as CVOC samples showing 'low' concentrations that were collected at times when the ITS indicated significant soil gas intrusion was occurring. This workshop will present draft Standard Operating Procedures (SOPs) for adding these ITS measures to ongoing investigations and seek feedback on this.
