Characterization of a combined release of LNAPLs and DNAPLs
- Marion Environmental, Inc., Chattanooga, TN (United States)
The subject of this investigation concerns a large quantity, subsurface release of an asphalt paint. The asphalt paint consisted of a mixture of asphalt (cut-back) and a commercial solvent that is 1,1,1-trichloroethane (TCA) based. The TCA appeared in the aquifer as a dense, nonaqueous phase liquid (DNAPL), and the balance of the material in the asphalt paint mixture appeared as light, nonaqueous phase liquids (LNAPLs). The site is located within a manufacturing facility which has been in operation since the late 1900s. There has been extensive development at the site, with attendant renovations and demolition of prior structures and placement of fill material, which has changed the natural surface soil conditions and complicated the local ground-water flow patterns. The complexity of the geology and hydrogeology of the site as well as the extent of the contaminant plume migration further complicated the site investigation. The investigation consisted of several elements: (A) Soil/Gas/Vapor Survey; (B) Surface-Water Sampling; (C) Deep and Shallow Cluster Drilling, Ground-Water Monitoring Well Installation, and Sampling; and (D) Ground-Water Flow and Transport Modeling.
