ABSTRACT:
A system for in-situ bioremediation includes a well extending into a saturated zone. The well includes a casing having two permeable sections in the saturated zone. Groundwater may be recirculated through the well and the saturated zone between the two permeable sections. Nutrients, such as oxygen and methane, may be added to the groundwater as it flows in the well. A venturi transfer device may be used to supply the nutrients.
