Percolation Testing
nounPronunciation: /ˌpɜːrkəˈleɪʃən ˈtɛstɪŋ/
Laboratory or field procedures that measure the rate at which water infiltrates through soil or mine reclamation material to assess drainage capacity and contaminant transport potential. Results determine suitability for final cover layers and liner systems.
Plain English
Testing how fast water soaks through soil or reclaimed material to check if it drains properly.
Etymology & History
Usage
"Percolation testing revealed that the clay-amended topsoil met infiltration requirements for the final cover system."

How is percolation testing conducted in the field?
Auger holes or pits are excavated, water is added, and infiltration rate is measured over specified time intervals.
Why Test Candidates on This?
