Upcoming Live Internet Seminars ITRC Perchlorate: Overview of Issues, Status, and Remedial Options - January 9. Improved analytical methodology has increased the known extent of perchlorate contamination in the U.S. A variety of remediation technologies are currently commercially available and being used for perchlorate remediation. This training, based on ITRC's Perchlorate: Overview of Issues, Status, and Remedial Options (PERC-1), explains why perchlorate is a hot topic in the environmental community including up-to-date information on sources, occurrences, toxicity and exposure, regulatory status and remediation alternatives.

This session will provide an introduction to definitions, forms and uses of nanotechnology. Superfund-related issues will be discussed including how these materials may be used to detect or treat contaminated media as well as recent efforts by the Environmental Protection Agency (EPA), the National Toxicology Program (NTP), and the National Nanotechnology Initiative (NNI) to characterize the risks these materials may pose. The session will feature Dr. Nora Savage, at the EPA Office of Research and Development as well as Dr. Nigel TechDirect: January 1, 2007 1 of 5 clu-in.ora/newsletters ------- Walker, at NTP, based at the National Institute of Environmental Health Sciences (NIEHS). The session will be moderated by Dr. William Suk, Director of SBRP at NIEHS. For more information and to register, see http://clu-in.org/studio . ITRC Remediation Process Optimization Advanced Training - January 25. Remediation Process Optimization (RPO) is the systematic evaluation and enhancement of site remediation to ensure that human health and the environment are being protected over the long term at minimum risk and cost. The purpose of this ITRC training is to present an overview of the material covered in five technical fact sheets that ITRC's RPO Team produced to enhance site remediation optimization and decision-making. The training modules provide additional information and techniques to improve project schedules, effectively manage resources, emphasize risk, and discuss tools to efficiently cleanup contaminated sites.

This training provides an introduction and overview of the processes, tools, and techniques used in investigation and remediation. These concepts are illustrated using an example munitions response site. Major steps in each process are identified and key regulatory considerations discussed. This training also identifies additional sources for more detailed information on key aspects of investigation and remediation. State regulators and others who need to understand the general processes involved in these critical aspects of the munitions response process will benefit from this training.

Direct-push wells have been used for temporary groundwater monitoring purposes for many years but are generally prohibited for use as long-term groundwater monitoring wells. Recent research indicates that direct-push wells are as well suited for long-term environmental groundwater monitoring purposes as conventionally constructed wells. This training introduces ITRC's The Use of Direct-push Well Technology for Long-term Environmental Monitoring in Groundwater Investigations (SCM-2, 2006), provides a background in the principles of direct-push wells, and presents the state of the art regarding recent research.

TechDirect: January 1, 2007 2 of 5 clu-in.ora/newsletters ------- Documents and Web Resources Long-Term Monitoring Network Optimization Evaluation for Operable Unit 2, Bunker Hill Mining and Metallurgical Complex Superfund Site, Idaho (EPA 542-R-06-005). This report, by the EPA Office of Superfund Remediation and Technology Innovation, presents a description and evaluation of the groundwater and surface water monitoring program associated with the Bunker Hill Mining and Metallurgical Complex Superfund Site (Bunker Hill) Operable Unit (OU) 2. A monitoring network consisting of 77 groundwater monitoring wells and 18 surface water stations was evaluated to assess its overall effectiveness at achieving the OU2-specific monitoring objectives, and to (1) identify potential opportunities to streamline monitoring activities while still maintaining an effective monitoring program, and (2) identify data gaps that may require the addition of supplementary monitoring points (January 2006, 126 pages).

This EPA report presents a description and evaluation of the groundwater monitoring program associated with the Wash King Superfund Site located in Pleasant Plains Township, Lake County, Michigan. A monitoring network consisting of 44 groundwater monitoring wells and five groundwater extraction wells was evaluated to identify potential opportunities to streamline monitoring activities while still maintaining an effective monitoring program (June 2006, 89 pages).
