Secondary Contaminant Transport
nounPronunciation: /ˈsɛkəndɛri ˈkɒntæmɪnənt ˈtrænspɔrt/
The movement of pollutants through soil and groundwater matrices via mechanisms including advection, dispersion, and diffusion following initial mine closure. Secondary transport occurs after primary contaminant release and determines long-term environmental impact zones.
Plain English
The spreading of mine contaminants through soil and groundwater over time after the initial pollution release.
Etymology & History
Usage
"Secondary contaminant transport modeling predicted that arsenic from the abandoned mine would reach the municipal well in approximately 15 years."
Style guide notes: Use full term on first mention; acceptable to abbreviate as SCT in technical sections after definition.

Frequently Asked Questions
What is the difference between primary and secondary transport?
Primary transport occurs at the pollution source; secondary transport describes contaminant movement through the environment afterward.
How do engineers model secondary contaminant transport?
Using hydrogeological software that accounts for groundwater flow, soil properties, contaminant sorption, and dispersion rates.
Why Test Candidates on This?
Critical for hydrogeological site assessments and reclamation design; tested in professional certification exams.
