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 »

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 »
Human-Health Risk Assessment – U.S. Can Company
U.S. Can contracted with Mundell to perform a human-health risk assessment of existing residual soil and groundwater impacts at its facility in Burns Harbor, Indiana. As part of this work, Mundell completed an exposure assessment that modeled groundwater flow, contaminant transport and indoor air vapor intrusion, and predicted potential receptors of impacted groundwater moving offsite……Read More »
3-D Characterization of Contaminant Distribution Guides Future Sampling and Remediation Efforts
Mundell developed a three-dimensional model of the distribution of total petroleum hydrocarbons (TPH) and polynuclear aromatic hydrocarbons (PNAs) for an active rail yard in Kentucky to support additional site sampling and remediation strategies……Read More »
Human-Health Risk Assessment – Herndon Harbor House
Mundell performed a human-health risk assessment for the development and subsequent habitation of a housing facility for the elderly at a site with known petroleum hydrocarbon soil and groundwater contamination in Herndon, Virginia. Exposure calculations indicated that the presence of a well-maintained, un-cracked foundation slab properly sealed with appropriate vapor and moisture barriers used with a passive ventilation system should reduce potential health risks to below acceptable levels……Read More »
