Presentation Descriptions:

Agricultural Non-Point Sources: Problems and Solutions
Brianna Schroeder & Todd Janzen, Janzen Agricultural Law, LLC

The Supreme Court of the United States is currently considering whether the Clean Water Act requires a permit when pollutants originate from a point source but are conveyed to navigable waters by a nonpoint source, such as groundwater, in County of Maui v. Hawaii Wildlife Fund. This decision will have far-reaching consequences for property owners, farmers, and consultants. Non-point sources were also the subject of a lawsuit out of Iowa against upstream, rural drainage districts in Des Moines Water Works vs. SAC County Drainage District et al. Meanwhile, the EPA has promulgated specific regulations regarding agricultural non-point sources, including land application of manure and concentrated animal feeding operations. States are implementing various voluntary measures to head-off greater federal and state regulation, such as Indiana’s Agricultural Nutrient Alliance. At the conclusion of this session, attendees will understand the changes we are seeing regarding the law on non-point source pollution and will be better prepared to react to non-point sources in the field.

Evaluation and Remediation of a Large Comingled Dilute VOC Plume in Western, Ohio – A Case Study
Craig Cox, Cox-Colvin & Associates

In 1998, the detection of chlorinated volatile organic compounds (CVOCs) in a public well field led Ohio EPA to begin a search for potential sources. By 2002, as many as four different consultants, representing local industries, had identified a comingled plume extending a distance of four miles. Following plume delineation, the sources of CVOCs were addressed through a variety of source area remedial actions (some of which are still proceeding). The case study is to presents, and provides opportunities to discuss, the techniques used to evaluate and remediate one of the largest commingled plumes with the Midwest.

Keeping Co-mingled Plumes from Confounding Your Interests: Practice Tips for the Consultant
Melissa Hamer-Bailey, Norris Choplin Schroeder LLP

Co-mingled plumes are challenging to investigate and remediate for consultants. But, they can also be fraught with consultant perils, from conflicts of interest, changing roles and scopes, and unexpectedly being asked to testify beyond your original role. Some may not lead to litigation for the consultant, but can cause difficulties by losing projects, not securing future work, loss of credibility/reputation, and scathing adverse testimony by those dreaded third-party reviewers. This presentation seeks to use site examples to assist consultants in better defining their role and scope and to recognize common litigation pitfalls from affidavit to deposition.

Panel Discussion on Addressing & Managing Commingled Groundwater Plumes
Moderated by David Gillay & Jennifer Baker, Barnes & Thournburg, LLC

As the economy continues to grow, there is a renewed focus on redeveloping environmentally challenged properties, increase in transactional work, and additional funds available to pursue regulatory closure. A common issue that can complicate redevelop and closure activities is commingled groundwater plumes. This panel discussion will provide lessons learned and perspectives from key stakeholders.

This session will cover items including:

  • Options for making risk-based decisions and managing closure with commingled plumes
  • What are the key issues with successfully obtaining regulatory closure
  • Enhance or refine your strategies to mange potential exposure and risk with commingled plumes

Separating Deep, Dilute and Diffuse Commingled cVOC
John Sohl, Columbia Technologies

The Palermo Wellfield (Wellfield) provides a portion of the drinking water for the City. Environmental investigations at the Site have been performed since the 1993 discovery of TCE in groundwater samples from the Wellfield. Remediation efforts began in 1998 by EPA, with relatively low concentrations remaining as a continuing potential environmental risk concern. Much of the groundwater within the Palermo Washington Wellfield Superfund Site (Site) is affected by the chlorinated solvents tetrachloroethylene (PCE) and trichloroethene (TCE) at concentrations in the low microgram per liter range. The Conceptual Site Model identified at least three separate potential sources. The Washington State Department of Transportation (WSDOT) initiated an efficient high-resolution site characterization (HRSC) investigative field screening approach to evaluate the current nature and extent of contamination to inform future liability management and develop alternatives for remedial action.

Significant Highlights:

  • Microgram/liter-range screening of chlorinated solvent concentrations as a newer application of direct sensing technology.
  • The approach was adapted to one of the largest study areas, approximately 100 acres in aerial coverage, attempted for HRSC.
  • The approach provided significant cost savings over traditional drilling and sampling approaches with a substantial increase in high-quality decision-making information.
  • The approach resulted in reduced impacts to local businesses and residences.
  • Original conceptual site model improved based on the investigation data.
  • The result was one of the most comprehensive low-level MIP study to date with over one mile of total vertical footage.
  • Achieved some of the deepest known MIP boring depths (up to 132 feet at one location) below ground surface, advancing the capabilities of this technology.
