Triad Environmental Solutions, Inc. (TES) was contracted by SESCO Group, Indianapolis, IN to provide Triad characterization support for the investigation of DNAPL PCE and the associated plume at a former wholesale dry cleaner site.  Limited previous data indicated a source near the former building and plume extending away from the building.  The project was conducted over ten field days using direct push soil and groundwater sampling and DSITMS performing EPA Method 8265.   Using the Triad approach, the source and plume were accurately characterized within the time and budget.
