Remediation of Gasoline with Injectate
About:
This site, an out of use gasoline service station, has stratigraphy consisting of silty sand interlayered with clay from 4 feet to 30 feet below grade surface. Groundwater is approximately 15 feet below grade with a target zone of 10 feet in thickness.
Two chemical oxidation products were used to complete remediation. The injectate was emplaced in the subsurface via innovative technology in order to increase the chemical oxidant radius of influence and thereby increase the contact between constituents of concern and the remediating material. Injections were completed at varying depths. Field data indicates that the injectate radius of influence was up to 18 feet from the injection locations.
Injectate continues to remediate the gasoline related constituents..
