Vadose-Zone Monitoring as a Key to Groundwater Protection and Optimization of Remediation Strategies - April 7, 2010, 1:00PM-3:00PM EDT (17:00-19:00 GMT). VMS is a novel vadose zone monitoring technology that is designed to provide in-situ, real time information on hydrological and chemical conditions of the percolating water in deep sections of the vadose zone. The data collected by the monitoring system provides early detection of subsurface pollution and allows optimization of remediation conditions. Up-to-date the system has been successfully implemented in several research projects on water flow and contaminant transport in various hydrological and geological setups including: (a) floodwater infiltration from stream channels and reservoirs, (b) land use impact on groundwater quality, (c) influence of intensive agriculture on groundwater quality, and (d) controlled remediation conditions of a contaminated vadose zone.

The third module examines the application of risk assessment to remediation operations in two case studies providing examples of how risk assessment has actually been implemented, based upon research and case studies conducted by the ITRC Risk Assessment Resources team. This training course describes a number of the reasons behind variations in risk-based screening values and their use in risk management. For more information and to register, see or .

ITRC Quality Considerations for Munitions Response Projects - April 13, 2010, 2:00PM-4:15PM EDT (18:00-20:15 GMT). This training introduces state regulators, environmental consultants, site owners, and community stakeholders to Quality Considerations for Munitions Response Projects (UXO-5, 2008), created by the ITRC's Unexploded Ordnance (UXO) Team. In this document, quality is defined as "conformance to requirements." To manage quality, the quality requirements of the project must first be understood. Requirements must be precisely stated and clearly understood by everyone involved. A plan is then put in place to meet those requirements. The UXO Team emphasizes taking a whole-system approach to designing, planning and managing a munitions response (MR) project to optimize quality. This training course is intended for an intermediate audience and assumes a basic understanding of specialized processes associated with MR projects. For more information and to register, see or .

Ecological Revitalization Project Profiles. EPA has developed this Web site to summarize timely information about the use of ecological revitalization at contaminated properties. Ecological revitalization refers to the process of returning land from a contaminated state to one that supports a functioning and sustainable habitat. Although the final decision on how a property is reused is inherently a local decision that often rests with the property owner, EPA actively supports and encourages ecological revitalization, when appropriate, during and after the assessment and cleanup of contaminated properties under its cleanup programs. This Web site contains information about completed and on-going projects where ecological revitalization was involved in solutions to various environmental concerns. These profiles provide information on site history, contaminants of concern and the ecological revitalization approach taken at each site. Technical considerations, long-term stewardship and operation and maintenance requirements are also included in each profile. View and use at .

Nanotechnology Project Profiles. EPA has developed this web site to summarize information about selected full-, field- and pilot scale applications of nanotechnology. Nanotechnology is an emerging technology that is generally defined as the ability to create and use materials, devices and systems with unique properties with a size of approximately 1 to 100 nanometers (nm). Applications of nanotechnology in environmental protection draw on nanomaterials' unique properties and include (1) sensors for improved monitoring and detection capabilities, and (2) treatment and remediation techniques for cost-effective and rapid site cleanup. Projects for this Web site are collected using information from technical journals and conference proceedings, as well as information obtained from technology vendors and site managers. The project profiles contain information on the types of contaminants treated, the type of nanomaterial used, the nanomaterial vendor, the length of operations, project scale and status, location, cost, monitoring and performance results, and points of contact and references.

Verification of Remediation of Land Contamination. A new report by Environment Agency explains how to check whether the remediation of land contamination has proved successful and met the intended goals. This new report offers guidance on designing a verification programme to increase confidence in the outcome of a remediation strategy. Four key stages are involved in the verification process: developing the remediation strategy, developing the verification plan, implementation of the verification plan, and long-term monitoring and maintenance. This report encourages the use of an evolving conceptual model, with uncertainties being reappraised as more information becomes available. Multiple lines of evidence should be collected to support the primary remediation goal, which is usually to reduce the level of a contaminant in soil or groundwater (February 2010, 87 pages).

A Framework for Assessing the Sustainability of Soil and Groundwater Remediation. This document presents the first phase of work by the United Kingdom's Sustainable Remediation Forum (SuRF UK), which is a framework for assessing the sustainability of soil and groundwater remediation, and for incorporating sustainable development criteria in land contamination management strategies. It helps assessors to identify the optimum land and/or groundwater remediation strategy and/or technique. Assessment of sustainable remediation is defined by SuRF-UK as "the practice of demonstrating, in terms of environmental, economic and social indicators, that the benefit of undertaking remediation is greater than its impact and that the optimum remediation solution is selected through the use of a balanced decision-making process" (March 2010, 63 pages).
