Battelle Sediments Conference

February 11, 2019

Learn about Barr’s project experience and meet our experts during our presentations and the poster session. Click here for more about the conference.

Event date: February 11-14, 2019

Location: Hilton New Orleans Riverside in New Orleans, Louisiana

Barr’s presentations include: 

  • “Balancing Remedial and Restoration Objectives for Sediment Capping on an Urban River,” Tom MacDonald (February 12, Track A3)—demonstrating that a balance between restoration and remediation in an urban setting can be achieved through an iterative design approach to satisfy stakeholder needs, protect an impermeable cap, and improve geomorphic function and habitat within a river impacted by historical industrial use.
  • “Modeling and Uncertainty Analysis for Remedy Selection and Design to Address Groundwater Discharging to Surface Water,” Katy Lindstrom (February 12, Track B1)—discussing a numerical groundwater model used to evaluate groundwater flow conditions and the influence of a river on groundwater flow, movement and natural decay of compounds in groundwater, and future conditions with various dredging and capping alternatives.

  • “Sediment Cap Design, Modeling and Construction,” Dale Kolstad (February 12, Track B1)— showing alternatives evaluated, design process, and construction of a multi-layer cap to isolate a freshwater river from remaining impacted sediments in a former industrial portion of Flint, Michigan.

  • “Great Lakes Legacy Act Used to Focus Stakeholders on Developing an Acceptable Remedial Alternative for Spirit Lake in the St. Louis River (Duluth) AOC”, Eric Dott and Eric Hedblom, co-authors (February 12, Track C1)— describing how EPA Great Lakes National Program Office and an industrial client accelerated the timeline to remedial design at a Great Lakes Area of Concern (AOC) site by facilitating focused stakeholder engagement.
Three Barr staff members will be presenting during the poster session on February 12 from 5:45 to 7:00 p.m. The presentations will include:

  • “Re-Creation of a Historical Island in the Mississippi River: Restoring Habitat in an Urban Setting,” Jamie Bankston—highlighting the design, construction, and habitat created by the reconstruction of Hall’s Island in Minneapolis, Minnesota, an award-winning project for the Minneapolis Park and Recreation Board and Mississippi Watershed Management Organization.

  • “Construction Quality Assurance during Environmental Dredging and Capping Projects,” Mike Ellis—focusing on the construction quality assurance practices implemented by Barr during a environmental dredging and capping project conducted in 2017.

  • ”A Balanced Approach to Pre-design Groundwater Data Collection for a Sediment Capping Remedy at a Great Lakes Estuary Site,” Eric Dott—covering a groundwater study developed by Barr and a partnering firm to provide focused groundwater-surface water interaction data for a remediation and restoration project in a seiche-influenced freshwater estuary.
