Where does remediation collide?

In environmental engineering remediation is the removal, containment, or breakdown of contaminants in soil, sediment, groundwater, or surface water so that a site meets a safety or regulatory standard. Approaches range from in-situ biorestoration, in which microbes degrade pollutants in place, to pump-and-treat and soil washing. The referent is the physical cleanup of a contaminated environment.[1][2]

Unit

The reduction of contaminant levels in soil or water toward a cleanup standard

Recovery means

A site is recovered when contaminant concentrations fall below the regulatory or risk-based target

Measured by

Tracked by contaminant concentrations over time against defined cleanup criteria

In Bolter and Grusin's media theory remediation is the process by which one medium represents, absorbs, and refashions another, the way digital media rework photography, film, television, and print. It oscillates between erasing the medium to feel immediate and foregrounding it as hypermediacy. The referent is a relation between media forms, not a chemical cleanup.[3]

Unit

The way a new medium represents and reworks an older one

Recovery means

Not applicable

Measured by

Analysed through how a medium borrows, embeds, or remakes the conventions of another

In education remediation (remedial or developmental coursework) is instruction that corrects gaps in foundational skills so a student can meet the demands of college-level or grade-level work. The referent is the repair of a learner's academic preparation, assessed by placement tests and later academic outcomes, and is unrelated to media forms or soil cleanup.[4]

Unit

Coursework that corrects deficits in foundational academic skills

Recovery means

A student is remediated once they reach the competency needed for standard coursework

Measured by

Judged by placement cutoffs and subsequent course completion, grades, and persistence
