and ground water. Mention of non-EPA documents or presentations does not constitute a U.S. EPA endorsement of their contents, only an acknowledgment that they exist and may
be relevant to the TechDirect audience. > Follow Us! Connect with CLU-IN on Facebook and Twitter. The Clean Up Information Network (CLU-IN) is now available through social networking sites such as Facebook and Twitter. Starting April 1, 2012, you will

Exposures - Long-term Health Consequences' features SRP research in revealing the vulnerability of a developing child by identifying how biological systems
are disturbed in this early period of life. The series will showcase cutting edge research findings that illuminate the consequences of early life exposures
to metals and organic contaminants of emerging concern. The third session of this series 'Early-life Exposures - Long-term Health Consequences Part 3: PCE
and Phthalates' features SRP grantees Dr. Ann Aschengrau (Boston University), Dr. John Meeker (University of Michigan) and Dr. Rita Loch-Caruso (University
of Michigan) and their work with early exposures and their resulting developmental effects. For more information and to register, see
. NARPM Presents...Institutional Controls - April 4, 2012, 1:00PM-3:00PM EDT(17:00-19:00 GMT). Come hear the latest on Institutional Controls (IC) during
this webinar. Assuming you know the basics about ICs: (1) they are non-engineered components of a remedy, including legal and communication mechanisms to
protect the remedy, and (2) most Superfund sites require effective ICs to ensure that remedies remain protective. However, as always, the 'devil is in the details.'
The planning and implementation of ICs has come a long way since the early days of Superfund, as we have had to create and innovate to make ICs work for unique situations.
Also, new developments help us with our endeavor for effective ICs. The session will start with a discussion of the latest guidance: the 'Planning, Implementing,
Monitoring, and Enforcing of Institutional Controls' (PIME) Guidance. We will also briefly touch on the 2011 'Recommended Evaluation of Institutional Controls,
Supplement to the Five-year Review Guidance' and other pending IC guidance. This is followed by case study examples involving local ordinances in Region 7,
and complex IC issues in Region 5. Finally, a special topic of implementing ICs on Tribal Lands will be examined. All questions and issues related to ICs are welcome!

(IDSS-1, 2011) technical and regulatory guidance document will assist site managers in development of an integrated site remedial strategy. This course
highlights five important features of an IDSS including: a conceptual site model (CSM) that is based on reliable characterization and an understanding of
the subsurface conditions that control contaminant transport, reactivity, and distribution; remedial objectives and performance metrics that are clear,
concise, and measureable; treatment technologies applied to optimize performance and take advantage of potential synergistic effects; monitoring based
on interim and final cleanup objectives, the selected treatment technology and approach, and remedial performance goals; and reevaluating the strategy
repeatedly and even modifying the approach when objectives are not being met or when alternative methods offer similar or better outcomes at lower cost. For

Reactive Barrier: Technology Update (PRB-5, 2011) and associated Internet-based training is intended to help guide state and federal regulators, consultants,
project managers and other stakeholders and technology implementers through the decision process when a Permeable Reactive Barrier (PRB) is being considered
as a remedy, or part of a remedy, to address contaminated groundwater; and to provide updated information regarding several technical aspects of the PRB using
information attained from the more than 15 years that the PRB has been a viable and accepted in situ remediation technology for contaminated groundwater. The
guidance and training provides an update on PRBs to include discussions of additional types of reactive media and contaminants that can be treated, design
considerations, construction/installation approaches and technologies, performance assessment and longevity. For more information and to register,

National Association of Remedial Project Managers (NARPM) training program in Kansas City, MO, and for the fourth year in a row, one of our most attended sessions
was on Greener Cleanups (GC). And like last year, we are offering those talks again to an online audience! EPA's definition of GC includes the practice of considering
the environmental effects of a remediation strategy (i.e., the remedy selected and the implementation approach) early in the process, and incorporating
options to maximize the net environmental benefit of the cleanup action. Back in August, we offered the first of three webinar sessions on the Footprint Methodology,
and this April we will showcase the remaining two webinars. We've got more case studies and maturing policy and guidance that we'd like to share with an online
audience. EPA's Technical Support Project, led by the Engineering Forum, will present these sessions. Each 2 hour session will include policy and/or case
studies, with time for Q&A along the way. For more information and to register, see . Greener Cleanups - EPA's Methodology for Understanding and Reducing a Project's Environmental Footprint (Final) - April 18, 2012, 1:00PM-3:00PM EDT (17:00-19:00
GMT). The process of cleaning up a hazardous waste site uses energy, water, and other natural or materials resources and consequently creates an environmental
footprint of its own. The US EPA recently released a methodology for quantifying the environmental footprints. The information obtained helps prioritize
efforts to reduce the footprint and improve the outcome of cleanups under any regulatory program. The two-hour seminar will: (1) discuss the genesis of the
effort; (2) summarize the methodology for estimating or quantifying the footprint and the associated metrics; and (3) provide an interactive case study to
allow participants to get a feel for the process of calculating an environmental footprint and eval
