TCE Health Effects
EPA's National Center for Environmental Assessment held a Symposium on Recent Scientific Research Related to the Health Effects of Trichloroethylene in Washington, DC on February 26-27, 2003. The symposium consisted of a series of invited presentations on recently published scientific findings related to the health effects of TCE. The focus of this symposium was published primary research, and no summary or conclusions were sought about the health risks of TCE. A transcript of the symposium will be made available on the NCEA Web page (http://www.epa.gov/ncea/) after the meeting. Information regarding this meeting can be found at:
 

IRIS Updates - 2004 Agenda
EPA has announced the 2004 agenda for updating its Integrated Risk Information System (IRIS). IRIS contains the agency's consensus information on human health effects of chemical in the environment. It lists the assessments completed in 2003 and those still underway. Trichloroethylene (TCE) and tetrachloroethylene (PCE), two compounds often at issue at vapor intrusion sites, are listed as underway but needing more time for completion because of complexity. The assessment of 1,1,1-trichloroethane for less than a lifetime exposure duration will also require a longer time frame. The complete agenda can be found at:

ITRC Background Document - Vapor Intrusion Issues at Brownfield Sites
The Interstate Technology and Regulatory Council (ITRC) has issued a document titled "Vapor Intrusion Issues at Brownfield Sites". The document includes approaches to VI used by California, Washington, New York, and South Carolina as well as Germany. It includes a listing of possible vapor intrusion remedies and their costs. The document is intended to be a resource for stakeholders involved with redevelopment projects and can be found at:

ITRC Vapor Intrusion Team
ITRC established an Vapor Intrusion team in 2004. The Vapor Intrusion Team will research and gather information on vapor intrusion, including when it needs to be evaluated, sampling and characterization techniques, and remediation technologies. The team plans to generate one informational and decision-assistance technical document, as well as training modules for both internet and classroom training. EnviroGroup is pleased to be part of the ITRC team. For more information, go to:

AWMA Vapor Intrusion Session
There will be a one day session on June 22 on "Advances in Indoor Air Vapor Intrusion: Guidance and Application" at the Air and Waste Management Association Annual Conference and Exhibition in Indianapolis, IN. More information on this meeting (see Session AB-7d) can be found at:

Midwestern States Risk Assessment Symposium
The Midwestern States Risk Assessment Symposium will include a session on vapor intrusion, focusing on studies of background concentrations, sources of background contaminants, and strategies for addressing background issues. The symposium will be held August 25-27, 2004 in Indianapolis. The call for paper and posters is open through April 1, 2004. For more information, go to:

EPA Seminar on Vapor Intrusion Now Available on CD Rom
EPA held Seminars on Indoor Air Vapor Intrusion in San Francisco, Dallas, and Atlanta from December 2002 -February 2003, focusing on the OSWER Draft Guidance for Evaluating the Vapor Intrusion to Indoor Air Pathway from Groundwater and Soils. A CD Rom containing the seminar, including detailed presentations on use of the vapor intrusion guidance, as well as mitigation methods and other topics, is now available. The document number is 625C03004 and the CD Rom can be ordered for free at the following web site:
