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 »

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 »
