Over the last 20 years, Canada and the United States have developed and implemented guidelines and standards for the investigation, mitigation, and remediation of contaminated properties. In all sectors of the economy, high profile contaminated sites, human health issues, litigation, and enormous cleanup costs have heightened the awareness of environmental issues relating to contaminated properties. Contaminated soil, sediment or groundwater in prime real estate and sensitive ecological locations has resulted in the loss of millions of dollars due to lack of development or ineffective management of these properties.
GOwen ENVIRONMENTAL was founded to provide specialized and leading-edge environmental training and networking through courses, conferences, and workshops. This Course was developed to provide a medium for the transfer of unbiased information and technology to clean up contaminated properties. The Course has evolved over the last seven years into an internationally recognized solution-based training program that brings together participants, regulators, consultants, and academics from across the globe.
THE ASSOCIATION FOR ENVIRONMENTAL HEALTH AND SCIENCES (AEHS) (www.aehs.com) AEHS members represent the many disciplines involved in making decisions and solving problems affecting soils, including chemistry, geology, hydrogeology, law, engineering, modeling, toxicology, regulatory science, public health, and public policy. AEHS recognizes the widely-acceptable solutions for contaminated soil that can be found through integrating scientific and technological discovery, social and political judgement, and hands-on practice. AEHS offers a medium for these solutions and is devoted to providing scientific, technical, regulatory, public policy, and practical information on soil contamination and cleanup through conferences, courses, Soil and Groundwater Cleanup Magazine, the Journal of Soil Contamination, the Human & Ecological Risk Assessment Journal, the Phytoremediation Journal, the Journal of Environmental Forensics, and the AEHS membership directory. AEHS has developed and conducted over 50 conferences and workshops for environmental professionals.
The Course is firmly established as far as content and instruction. The Course is sponsored by one of the largest environmental associations in North America. Over the last six years, the Course has received support and sponsorship from major environmental associations world-wide. The instructors represent academia, government, and the private sector; all are leaders in their respective fields. This framework provides for an unbiased transfer of information that provides individuals who own, regulate, investigate, remediate or are impacted by contaminated properties with a solid theoretical and practical foundation in contaminated site management. The management of these sites is a multi-disciplinary task. This course integrates all the disciplines necessary to successfully, efficiently and economically manage or make decisions regarding these sites.
Course participants will receive theoretical and practical foundations, as well as important information regarding regulatory compliance aspects of contaminated site management. This knowledge will be coupled with a hands-on approach to understanding the tools and techniques for managing contaminated sites. Some experience is helpful, but not necessary, as the Course teaches basic principles before addressing more advanced topics.
This is the only one week indoor-outdoor course being offered globally that covers all issues related to managing subsurface contamination, from theory to practice. The Course’s 17 instructors are from academia, private industry, and government in North America and are recognized as leading experts and teachers in their respective fields. These instructors will provide students with access to a broad base of practical experience and an excellent opportunity to network with leading professionals.
Regardless of your level of expertise, the combination of information presented during this Course will not be found elsewhere and will provide you with the knowledge and confidence to effectively manage contaminated sites. This Course will provide participants with the competitive edge required in this rapidly evolving field.
As part of the education process, selected case histories of soil, sediment and groundwater investigations, remediations and risk assessments will be studied to further emphasize the practical aspects of each lecture topic. While a good number of 2-3 day short courses are offered on some aspects of contaminated site management, there are few one-week courses offering the opportunity for in-depth learning of a more complete range of issues. The extent of recent developments in the science and technology of contaminated and hazardous waste site management is such that one would be required to attend many short courses in order to be brought up to speed. Our intensive one-week course, with additional workshops and outdoor demonstrations, is an attractive alternative for busy professionals.
This week-long course allows for a half-day of outdoor seminars to demonstrate the various site characterization and remediation technologies currently being used on sites across North America today. Four optional nightly seminars will provide the attendee with hands-on computer workshops to demonstrate the application of environmental decision support software, groundwater modeling and risk assessment modeling tools.
The majority of courses provide two or three instructors to cover an extensive array of topics in two days and charge the same amount for registration for two days as this course charges for five. The 17 instructors in this course, along with the many technology demonstrators, will provide students with a unique access to a very broad base of practical experience and an excellent opportunity to network with leading professionals.
This Course provides an unparalleled synthesis of technical information and applied knowledge in contaminated and hazardous waste site management.
