Document Description: In situ treatment for chromium-impacted soil in a former wood treatment area (~ 0.6 acres) by injecting a dilute mix of alcohol and corn syrup. The project involves installing 32 injection wells that target ~ 30,000 cubic yards of soil. The injection solution will consist of potable water with ~ 2 grams per liter (g/L) of total organic carbon from corn syrup (75 percent by weight) and methyl alcohol (25 percent by weight). Ferrous sulfate may be added up to a concentration of 1 g/L of ferrous iron. The treatment solution will injected over a period of up to 6 months. The total volume of treatment solution will be 13.8 acre - feet, equal to 1.5 times the soil pore space volume. After completing the cleanup, the injection wells will be properly abandoned and the ground surface restored.
