Using GIS Tools to Analyze, Compute, and Predict Pollution, Session I - Exposure Assessment in the Field and Links to Human Health - November 12, 2013, 1:00PM-3:00PM EST (18:00-20:00 GMT). Preterm birth, the leading cause of neonatal mortality in the U.S., may be associated with exposure to legacy and emergent contaminants in the environment. Puerto Rico has one of the highest rates of preterm birth, as well as density of Superfund Sites in the United States. As part of NIEHS's Superfund Research Program, the Puerto Rico Testsite for Exploring Contamination Threats (PROTECT) is exploring the relationships between exposure to hazardous chemicals and preterm birth in northern Puerto Rico. Particular attention is given to chlorinated volatile organic compounds and phthalates, although biomarkers of phenols, metals, and parabens exposure are also being explored as precursors of preterm birth. Identification of associations between contaminants and preterm birth requires collection and integration of complex multi-disciplinary datasets. The first presentation will describe the data management system being developed by PROTECT to integrate, manage, analyze, and relate environmental, demographic, exposure biomarkers, and birth outcome data. The discussion will center on the applicability of the system, built on a foundation of Earthsoft's EQUIS�, to assess the extent of groundwater and tap water contamination, identify other modes of exposure, define patterns in biomarkers of exposure and birth outcomes from an ongoing birth cohort, perform relational queries, and map spatial patterns that can be directly visualized with ArcGIS. Toxic metals are widespread environmental contaminants that are known human carcinogens and/or developmental toxicants. The levels of metals in private well water are federally unregulated. The second presenter will describe two studies that used GIS mapping in North Carolina to examine 1) the spatial patterns of arsenic levels private wells, and 2) the association between private well levels of arsenic, cadmium, manganese, and lead and birth defects prevalence. The studies used a statewide database of private well contaminants collected by the North Carolina Department of Health and Human Services Division of Public Health as well as data from the North Carolina Birth Defects Monitoring Program.

ITRC Environmental Molecular Diagnostics: New Tools for Better Decisions - November 13, 2013, 2:00PM-4:15PM EST (19:00-21:15 GMT). Environmental molecular diagnostics (EMDs) are a group of advanced and emerging analytical techniques used to analyze biological and chemical characteristics of environmental samples. Although EMDs have been used over the past 25 years in various scientific fields, particularly medical research and diagnostic fields, their application to environmental remediation management is relatively new and rapidly developing. The ITRC Environmental Molecular Diagnostics Fact Sheets (EMD-1, 2011), ITRC Environmental Molecular Diagnostics Technical and Regulatory Guidance (EMD-2, 2013) and this companion Internet-based training will foster the appropriate uses of EMDs and help regulators, consultants, site owners, and other stakeholders to better understand a site and to make decisions based on the results of EMD analyses. At the conclusion of the training, learners will be able to determine when and how to use the ITRC Environmental Molecular Diagnostics Technical and Regulatory Guidance (EMD-2, 2013); define when EMDs can cost-effectively augment traditional remediation data sets; and describe the utility of various types of EMDs during remediation activities.

CEC Training for OSCs...Pesticide Emergencies (FIFRA ER for EPA OSCs) - November 13, 2013, 1:00PM-4:00PM EST (18:00-21:00 GMT). Accidental release or indiscriminate discharge of pesticides and pesticide wastes into the environment can harm people and contaminate soil, sediment, surface water and groundwater. Responding to these incidents can pose unique concerns because most pesticides are designed to harm or kill pests, and can similarly harm or kill people. This is a 3-hour webcast training that provides practical information on the characteristics of common pesticides and pesticide formulations, human health and ecological hazards associated with sources of pesticide exposure, environmental fate of pesticides, identification and use of chemical-specific information, legal and regulatory considerations and emergency response involving pesticide incidents. The target audience for this course is new and mid-career EPA OSCs with an interest in learning about reasonable steps to respond quickly and decisively to threats posed by accidental release or indiscriminate discharge of pesticides and pesticide wastes. This course assumes some CERCLA response experience and is well suited to OSCs with 2 to 7 years of experience, or any OSC with a specific interest in a response involving pesticides. The webcast should also be of interest to State and local emergency responders. For more information and to register, see http://clu-in.org/live .

CEC Training for OSCs...Pipeline Emergencies - November 14, 2013, 2:00PM-5:00PM EST (19:00-22:00 GMT). Approximately 327,000 miles of natural gas transmission pipelines, 1.8 million miles of natural gas distribution pipelines and 161,000 miles of liquid pipelines safely transport natural gas and a range of liquid petroleum products daily. Like any industry that deals with hazardous materials, there are potential risks in the manufacturing and transportation processes. Pipeline Emergencies is a 3-hour webinar training course that provides practical information on how to respond safely and effectively to pipeline incidents and emergencies. The purpose of the course is to provide participants with the knowledge and understanding of the EPA's regulatory authority regarding pipeline emergency planning and response operations, how pipelines operate, the common products that may be transported through both transmission and distribution pipeline systems, the various roles and responsibilities among emergency responders and government and industry when responding to an incident and pipeline emergency response operations. The target audience for this webinar course is new and mid-career On-Scene Coordinators (OSC) with an interest in learning about pipeline emergencies. This webinar does not address tactics and field methodology as that information is better suited for face-to-face or field demonstration training.
