Abstract

In one implementation, a direct - push oxidant candle apparatus for the treatment of contaminated groundwater through direct - push installation methods includes : a drive tip positioned at a bottom end of the apparatus , the drive tip having one or more front surfaces that are shaped to create a bore as force is applied to an opposite base surface of the drive tip ; a structural pathway that is connected to and extend upwardly from the base surface of the drive tip ; one or more oxidant delivery devices that are enclosed within the structural pathway ; and one or more fluid supply lines that extend from one or more locations outside of the bore and that terminate at or near a bottom end of the structural pathway so that fluid supplied through the fluid supply lines travels through the structural pathway and along the one or more oxidant delivery devices.
