The EPA Region 8 Grant Writing Workshop is designed to assist local governments, tribes and nonprofit organizations to better understand the proposal criteria and selection process for EPA's Brownfields Assessment, Cleanup and Revolving Loan Fund grants. EPA Region 8 is comprised of communities in Colorado, Montana, North Dakota, South Dakota, Utah, Wyoming, and 27 tribal nations. Major workshop agenda topics will include:What are the different grant types EPA provides for brownfields?Who is eligible to apply?What is the grant application process?What are threshold and ranking criteria and how have they changed this year?What makes a good application?Grant writing tips To view the slides associated with this audio, please visit http://www.clu-in.org/conf/tio/R8BFGuidelines_091508/

This workshop is similar to one presented at the June 2008 Triad Conference. It will cover field analytical approaches, followed by LTM network design and implementation, then integration of sensors and logistics into the development of the CSM, and will finally wrap up with examples of automated monitoring (which includes contouring and model update). This workshop will cover best-of-class approaches for CSM development with an emphasis on direct-push technologies, then integrate new approaches to update this in the most time/cost-effective manner. While the models are conceptual, the workshop will discuss analytical components to the model to make quantification possible.

A Systematic Approach for Evaluation of Capture Zones at Pump and Treat Systems presents a systematic approach for the evaluation of capture zones at pump and treat systems, and provides an overview of a recently published USEPA document on the topic (EPA 600/R-08/003, January 2008). The target audience for the course is project managers who review those analyses and/or make decisions based on these types of analyses. This course will highlight:The importance of capture zone analysis during ground water remediation, particularly for sites requiring containmentKey concepts of capture, such as "target capture zones" and "converging lines of evidence"Typical errors made in capture zone analysisIn addition, steps associated with a systematic approach for capture zone analysis will be discussed. These steps include the following:Step 1: Review site data, site conceptual model, and remedy objectivesStep 2: Define site-specific Target Capture Zone(s)Step 3: Interpret water levelsPotentiometric surface maps (horizontal) and water level difference maps (vertical)Water level pairs (gradient control points)Step 4: Perform calculations (as appropriate based on site complexity)Estimated flow rate calculationCapture zone width calculationModeling (analytical and/or numerical) to simulate water levels, in conjunction with particle tracking and/or transport modelingStep 5: Evaluate concentration trends Step 6: Interpret actual capture based on steps 1-5, compare to Target Capture Zone(s), and assess uncertainties and data gaps Examples will be used to demonstrate key aspects of capture zone analysis.

This 8-part internet seminar series covers material that generally is not presented in XRF presentations or training courses. This is an applications course: how can a FP-XRF be used so that its data are highly dependable and defensible. Sampling design and sample handling options for FP-XRF will be covered, along with the benefits and limitations of each. Analytical and QC concerns common to using XRF are also discussed. This course will be of interest to staff developing XRF sampling and analysis plans, reviewing the plans for quality assurance, field operators, and users of XRF data for making project decisions. Concepts and practice will be illustrated using experiences from actual field projects. The capabilities of newer FP-XRF instruments will be described. Participants may register for any session of interest, but are highly encouraged to attend all 8 sessions for the full benefit of the course. Session 8 This session will review Q&A review for all sessions and resources. To view the slides associated with this audio, please visit http://www.clu-in.org/conf/tio/xrf_082808/

This seminar will cover the results of an ESTCP-funded (www.estcp.org) demonstration of the use of the high-resolution piezocone direct push sensor probe to determine direction and rate of ground water flow in three dimensions. Field hydraulic measurements can be used to determine seepage velocity distributions through interpolation methods recently incorporated into Groundwater Modeling System. Probe data comprised of soil type and co-located hydraulic information is particularly amenable to innovative data fusion based interpolations available through the modeling platform. Following chemical concentration data collection, these innovative data processing approaches allow for the determination of flux distributions at resolutions and spatial configurations never before available. Field scale data collection, interpolation, and modeling results will be presented and discussed. Final technical report for the ESTCP demonstration can be found at http://www.estcp.org/Technology/upload/ER-0421-FR.pdf.
