In-situ remediation system for volatile organic compounds with deep recharge mechanism
Abstract
A method and apparatus for the treatment and remediation of a contaminated aquifer in the presence of an uncontaminated aquifer at a different hydraulic potential. The apparatus consists of a wellbore inserted through a first aquifer and into a second aquifer, an inner cylinder within the wellbore is supported and sealed to the wellbore to prevent communication between the two aquifers. Air injection is used to sparge the liquid having the higher static water level and, to airlift it to a height whereby it spills into the inner cylinder. The second treatment area provides treatment in the form of aeration or treatment with a material. Vapor stripped in sparging is vented to the atmosphere. Treated water is returned to the aquifer having the lower hydraulic potential.
