Asphalt Testing Site Chemical Oxidation CVOCs
A release of TCE at a temporary asphalt field testing station in Branch, Michigan, resulted in the development of 1,400-foot-long contaminant groundwater plume. FTCH was retained by MDOT to implement groundwater cleanup activities using chemical oxidation. Potassium permanganate was selected as the oxidant and the remediation was performed during three separate phases over three separate portions of the plume (starting in the source area). The remedial activities have resulted in a 75-percent reduction in the extent of the plume. The long-term goal is for natural attenuation of the remaining impacted groundwater.
