2 In 1997, IBM reported a spill of methyl chloroform (EPA, 2010) IBM had a hydrogeologic report done that indicated a higher than expected plume, including TCE (EPA, 2010). In 2002 the NYS DEC ordered IBM to do a comprehensive assessment of contaminant vapors in surrounding areas

3 Participants will learn about what Tetrachlorethene (TCE) is How TCE impacts Health The Endicott, New York Superfund site and what it means to you Research and Recommendations Where to get more information

4 Vapor Contaminants had migrated to area buildings This includes buildings in the Village of Endicott and Town of Union TCE is the pollutant of most concern regarding indoor air (EPA, 2010). In 2004, site reclassified as a class 2 Superfund site

5 Tetrachloroethene=TCE Volatile Organic Compounds=VOCs Health Consequences=cancer, organ damage, and/or birth defects (NYSCEC, 2006) No formal regulations for evaluating TCE exposure, only suggested guidelines A 2005 Health Statistics Review reported increased rates of testicular and kidney cancer, as well as heart birth defects

6 In 2009 3 researchers conducted a study on the impact of TCE on the immune system (Cooper, Makris, & Jinot) Studies with mice indicated lupus like symptoms after exposure to TCE Human studies are limited Some recent studies indicated a causal relation between exposure and disease, Skin irritation and liver issues

7 A 2010 a long term study of NASA research facilities and vapor intrusion was published TCE was present in groundwater TCE levels analyzed were higher indoors than outdoors This study demonstrates how TCE can be effectively measured if it is present due to vapor intrusion Demonstrates how groundwater contamination can result in vapor intrusion

8 Despite scientific evidence-lots of controversy and debate No real standards, only proposed limits Hard to accurately measure More research needs to be done Study published by Brenner (2010) is promising

9 Monitoring-testing costs between $2000- $3000 annually (NYSCEC, 2006) Mitigation-installing specialized venting systems to eliminate TCE costs from $1000- $30000 depending on the complexity of the structure, and could be higher (NYSCEC, 2006) Over time, mitigation costs are equal or less than annual testing

10 IBM installed mitigation systems in all buildings within the plume in the village of Endicott Viewed as being responsible in vapor mitigation management

11 Use of current technology to mitigate exposure Liquid Boot© Gas Vapor Mitigation System Spray on Barrier Can be used on existing and new construction

12 The NYSCEC (2006) recommends the following: DOH establish exposure limits based on lowest levels studied. DOH and DEC implement mitigation where TCE vapor intrusion is detected and confirmed If someone lives or works in a building near a site, they can request indoor air testing Cleanup of a site should be done as quickly and aggressively as possible Continuing education of communities

13 Find out if you live in the impacted plume area Request information from the Broome County Department of Health Ask for your building to be tested and/or mitigated for TCE Information available at: tm tm Review the Citizen Participation Action Plan at:
