Upcoming Live Internet Seminars  
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. For more information and to register,

ITRC Risk Assessment and Risk Management: Determination and  
Application of Risk-Based Values - April 8, 2010, 11:00AM-1:15PM  
EDT (15:00-17:15 GMT). This training course describes the  
development and application of risk-based screening values. The  
first module provides a review of key risk assessment concepts  
related to risk management. The second module focuses on the  
process by which risk-based levels are derived in different  
states. 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.

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 .  
Field Operations Records Management System II Lite (FORMS II  
Lite) Training for Acquiring Superfund Analytical Services in  
Region 6 - April 22, 2010, 9:00AM-1:00PM EDT (13:00-17:00 GMT).  
The FORMS II Lite software is a flexible and easy-to-use,  
stand-alone, Windows-based application that simplifies and  
accelerates the sample documentation process. FORMS II Lite  
software is the preferred means of creating Contract Laboratory  
Program sample documentation. FORMS II Lite reduces the  
generation of hand written documents by nearly 70 percent.  
Specifically, FORMS II Lite generates sample labels, bottle  
tags, and Chain of Custody (COC) forms; tracks samples from the  
field to the laboratory; facilitates electronic capture of  
sample information into databases; and exports data  
electronically as .xml, .dbf, or .txt files. For more  
information and to register, see .  
Assessing EDCs in the Field: New Approaches to Old Challenges -  
April 22, 2010, 1:30PM-3:30PM EDT (17:30-19:30 GMT). The  
Superfund Research Program (SRP) presents 'Assessing EDCs in the  
Field: New Approaches to Old Challenges' featuring Dr. Gerald  
(Gary) Ankley (USEPA/ORD Mid-Continent Ecology Division) and Dr.  
Nancy Denslow (University of Florida). Dr. Ankley will focus on  
the problems EDC present for ecological risk assessment and will  
talk about the types of assessment tools needed and their  
potential applications. Dr. Denslow's presentation will show how  
molecular biomarkers and 'omics' technologies may be useful in  
risk assessment, focusing on a Lake Apopka study of largemouth  
bass, fathead minnows, and organochlorine pesticides. This is  
the first session of the RiskeLearning Spring/Summer 2010 series  
'Ecological Risk: New Tools and Approaches.' For more

ITRC Use of Risk Assessment in Management of Contaminated Sites  
- April 27, 2010, 2:00PM-4:15PM EDT (18:00-20:15 GMT). This  
training course identifies how various risk-based approaches and  
criteria are applied throughout the processes of screening,  
characterization, and management of contaminated sites. The  
training course and associated overview document, Use of Risk  
Assessment in Management of Contaminated Sites (RISK-2, 2008),  
are intended for risk assessors and project managers involved  
with the characterization, remediation, and/or re-use of sites.  
The training and overview document provide a valuable tool for  
federal and state regulatory agencies to demonstrate how site  
data collection, risk assessment, and risk management may be  
better integrated. For more information and to register, see or .  
New Documents and Web Resources  
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
