Vegetation-based remediation systems, remediation straw and cartridge apparatuses for groundwater treatment, and methods for installation of vegetation-based remediation systems

A vegetation-based remediation system, the vegetation-based remediation system comprising:

• a liner sleeve for positioning within an excavated hole;
• a bottom impermeable barrier on which the liner sleeve resides, the bottom impermeable barrier being positioned at a bottom of the excavated hole;
• a backfill of soil mixture that is used to fill the liner sleeve once the liner sleeve is positioned within the excavated hole;
• a straw for insertion in a hole through the soil mixture, the liner sleeve, and the bottom impermeable barrier and into soil below the bottom impermeable barrier such that the straw extends below the bottom impermeable barrier upon installation upon installation, the straw comprising an inlet well screen and an outlet well screen, the inlet well screen positionable below the bottom impermeable barrier upon installation and the outlet well screen positionable above the bottom impermeable barrier inside the liner sleeve adjacent a portion of the soil mixture upon installation of the straw;
• a treatment cartridge that is insertable into and removable from the straw, the treatment cartridge comprising a filter section having treatment media therein, the filter section configured to be positionable within the straw between the outlet well screen and the inlet well screen of the straw upon installation;
• and
• a plant configured to be planted within the soil mixture in the liner sleeve.
