Upcoming seminars and workshops

December 7, 2016: Issues & Trends - Hazardous Waste Determinations and Management Options at Remediation Sites in Wisconsin

Gary Edelstein, an engineer with the Remediation and Redevelopment Program, will present an overview of the RR Program’s “Guidance for Hazardous Waste Remediation,” with concentration on hazardous waste and contained out determinations, contaminated media management options and DNR review procedures. The Program is providing this training now in part to respond to recent inquiries regarding guidance implementation and agency review procedures, including who has responsibility for making certain decisions. It will also provide an introduction for those who aren’t familiar, and a refresher for those who are.

  • Time: noon - 1 p.m.
  • Join by phone: 1-855-947-8255, passcode: 6612 745#
  • Questions in advance may be sent to
  • No pre-registration required

Previous seminars and workshops

November 9, 2016: Issues and Trends - Organic Chemistry Refresher - Petroleum & Chlorinated Solvents

The 1.5 hour session was presented by Marquette University assistant professor Llanie Nobile, PhD. She begins by discussing the volatility, solubility and reactivity of gasoline mixtures (fresh and weathered). Dr. Nobile then continues with volatile organic compounds, in particular – chlorinated solvents. Nomenclature and reactivity of chlorinated VOC’s are also covered.

Check out the schedule of Issues & Trends webinars [PDF] to see what is on the horizon.

November 2, 2016: Brownfields 101 - Redevelopment Resources for Local Governments

The DNR's RR Program hosted a day-long seminar on November 2nd, 2016 for local government officials on brownfield redevelopment. Experts discussed strategies and tools to help communities turn around and capitalize on underused or abandoned properties.

Presentations are available on the RR Program Training Library.

October 5, 2016: Issues & Trends - Maintenance Plans: Designing for Compliance after Site Closure

Jane Lemcke, the RR Program’s team leader for standards and streamlining, presents the October Issues & Trends conference call on maintenance plans for sites that close with continuing obligations. The objective for Jane’s presentation is to provide environmental professionals with tools for writing maintenance plans that are easy for responsible parties to understand and implement. Recommendations are offered on personalizing the maintenance plan template according to the Maintenance Plan Example Template for a Straightforward Site (RR-980) [DOCX] and Maintenance Plans for Vapor Mitigation Systems/Vapor Intrusion Response Actions/Vapor Barriers (RR-981) [PDF]

Check out the schedule of Issues & Trends webinars [PDF] to see what is on the horizon.

September 7, 2016: Issues & Trends - NAPL Saturation Concepts

David Swimm, a hydrogeologist with the RR Program, discusses core-based saturation measuring, including new technologies that allow much improved imaging of LNAPL accumulations, especially as it pertains to recoverability and residual saturation concepts.

August 3, 2016: Issues & Trends - Calculating Background Levels for Common Soil Contaminants

The presentation is available on the RR Program training library.

June 1, 2016: Issues & Trends - LNAPL Transmissivity (Tn) – How quickly does petroleum product move within aquifers?

After the Interstate Technology & Regulatory Council (ITRC) suggested Light Non-Aqueous Phase Liquid (LNAPL) Tn as a remedial performance metric in its 2009 guidance (“Evaluating LNAPL Remedial Technologies for Achieving Project Goals”), interest in the use and meaning of Tn measurements has increased significantly. LNAPL Tn values offer a vastly improved performance metric over well-based LNAPL thicknesses. In regards to remedial hydraulic recovery, it is one of several factors that can be used to judge the “maximum extent practical.” Consequently, it increasingly is becoming an important parameter to understand and measure.

The presentation will emphasize the context of LNAPL Tn values, which should provide a practical indication of its utility and limits. We will review the various field techniques and required measurements needed to evaluate LNAPL Tn. Lastly, DNR will also review analyses used to estimate LNAPL Tn under various aquifer conditions. 

The presentation is available on the RR Program training library.

May 4, 2016: Issues & Trands - Post Closure Modifications: Covers and Property Boundary Changes

Jane Lemcke, DNR, presents information on the post-closure modification process and discusses examples provided in the guidance, Post-Closure Modifications: Changes to Property Conditions after a State-Approved Cleanup (RR-987) [PDF].

The presentation is available on the RR Program training library.

April 6, 2016: Issues & Trends - Contaminated Materials Management

Policy and Technical Resources Section Chief Judy Fassbender leads a conference call on the NR 718 process for managing contaminated soil at a location other than a licensed facility approved to accept that waste, including a discussion of the requirements for immediate, interim and remedial actions.

Judy highlights the applicability of NR 718 and the Low Hazard Exemption process as they relate to management of contaminated soil and other solid waste material.  She touches on an introduction to the planned receiving site tracking  process for future identification of sites where contaminated materials have been managed and where continuing obligations have been placed. Judy also summarizes the information to be considered when making a waste determination.

The presentation is available on the RR Program training library.

February 3, 2016: Issues and Trends presentation - Screening Closed BRRTS Sites for Vapor Risk: How Information in RR-042 Can Help Speed Property Transactions

The RR Program’s February Issues & Trends event features DNR Hydrogeologists Alyssa Sellwood and Terry Evanson with a discussion on how recent agency guidance (DNR Case Closure Continuing Obligations: Vapor Intrusion - RR-042) can help environmental consultants when they screen closed BRRTS sites for vapor risk.  

Property transactions often involve assessing the environmental risks at closed contaminated sites. Many contaminated properties have been closed without assessing the vapor pathway. Alyssa and Terry explain how the DNR guidance can help speed up some property transactions in these circumstances.

The presentation is available on the RR Program training library.

January 20, 2016: Issues and Trends presentation - Importing Soil to VPLE Sites

The DNR Remediation and Redevelopment (RR) Program held a training opportunity on a new guidance titled Obtaining DNR Approval Prior to Use of Imported Soil and Other Fill Materials on Voluntary Party Liability Exemption Sites (RR-041).  Any environmental professional involved with cleanup and redevelopment of real estate is encouraged to watch this webinar.

Judy Fassbender and Michael Prager from the RR Program explain why the guidance was issued, walk through the process and answer questions. Michael and Judy also discuss the DNR approval process and how to handle common case situations. To prepare for the training please read the new guidance document prior to the presentation.

The presentation is available on the RR Program training library.
