Mundell effectively confirmed an on-site source at the Michigan Plaza site and fully delineated chemical impacts to soil and groundwater from past site operations. Injection of CAP-18, a soybean oil bioremediation product, was chosen as the best remedial option. Within three months of the injection events, reductive dechlorination responses were evident at monitoring wells immediately down gradient of the injection locations. Over time, this same response has been observed moving further downgradient across the site……Read More »

Soil Vapor Extraction and Air Sparging Removal Action on EPA CERCLA Site at Former Residential Dry Cleaner
In 2005, the EPA issued an order to remove PCE contamination from a former dry cleaners site as it presented a potential endangerment to the public health. Mundell was contracted to develop a plan to achieve unsaturated soils and groundwater cleanup goals while controlling PCE soil gas vapors that had intruded into the foundations of residences. In 2013, after 7 years of Mundell’s remediation system and techniques, the EPA approved completion of the soil removal action, indicating that on-site PCE soil source had been remediated. Approximately 1.65 tons of PCE had been removed by the system. Mundell continues to monitor groundwater to track progress of reductive de-chlorination in the residual off-site chlorinated groundwater plume……Read More »
Mundell Speaks at Geotechnical Society Workshop
As a part of the Purdue Geotechnical Society Workshop in West Lafayette, IN at April 19, 2013 John Mundell presented “The Design of Permeable Reaction Barriers (PRBs) for the Remediation of Chlorinated Solvent Plumes.” In addition, John spoke on the closing panel, wrapping up which bring together experts on the workshop’s theme – Soilmakers: Engineering…..Read More »
The Design of Permeable Reaction Barriers (PRBs) for the Remediation of Chlorinated Solvent Plumes (2013)
Mundell, J.A., “The Design of Permeable Reaction Barriers (PRBs) for the Remediation of Chlorinated Solvent Plumes” Purdue Geotechnical Society Workshop, West Lafayette, Indiana, April 19, 2013.
Site Assessment at a Former Gasoline Station
Mundell used EM-61 metal detection in conjunction with localized ground penetrating radar to characterize metal objects beneath a former gas station site. In the end, a single, 3,000 gallon UST was located and determined to be the source of significant soil and groundwater impacts across the site. The use of geophysics on this project was crucial to its successful completion……Read More »
