Bernd W. Rehm PG,CPG Solution Manager ReSolution Partners,LLC

Bernd Rehm received a MS in hydrogeology from the University of Waterloo in 1977.  In the last 3 years he has characterized soil, groundwater, and sediments and designed and implemented remedial actions at sites across the central and eastern US and Europe under a variety of state and federal program.  Since 2004 he has been part owner and Solution Manager for ReSolution Partners, LLC, providing remedial design and implementation support to consultants, contractors, and owners. 

Presentation Description
In Situ Stabilization of Zinc in Groundwater
In situ metals stabilization provides a viable means of reducing the leachable concentrations of metals in soil and groundwater.  The presentation will use a zinc-contaminated brownfields site to illustrate issues that need to be considered with this technology from design through bench- and pilot-scale testing, and full-scale application.

Poster Descriptions
Remediation of a Mixed Solid Waste Using Metals Stabilization and VOC Oxidation
Concurrent remediation of metals and oxidation of organics in a hazardous solid waste can be an integral component of site remediation and waste management.  Stabilization and destruction technologies can be implemented to render the waste non-hazardous for both types of constituents, reducing the cost of waste disposal.  Since the remediation chemistry can be different for each of the mixed constituents, concurrent remediation can often have competing reactions.  The challenge for treating the waste is finding and applying manageable complimentary remediation chemistries. 

Enhancing the Natural Environment with Metals Stabilization and On-site Management
Traditional remediation approaches for heavy metals range from off-site hazardous waste disposal to a variety of chemical treatments to reduce metals' leachability, allowing for off-site non-hazardous disposal.  These approaches, although regulatorily sound, can have significant ancillary environmental impacts that include an increased carbon footprint associated with transportation of waste and borrow materials, increased resource use (i.e., backfill), and reduced landfill capacity.  Emerging remediation alternatives can provide "greener choices," reducing ancillary environmental impacts.
