Based on unsatisfactory results derived from active soil gas sampling at other similar dry cleaner sites, the Kansas regulator selected the GORE™ Survey to delineate subsurface impact by dry cleaning solvents. Ease of installation allowed for the deployment of the GORE™ Modules through the building slab, adjacent paved parking lot, and along sewer lines. The soil gas results located source and extent of impact, and aided the Kansas DHE in optimizing chemical injection and vapor extraction locations.
