The âPerc Testâ. A Perc Test (also known as âPerk Testâ, and more formally known as a Percolation Test), is a soil evaluation that tests the rate at which water drains through soil.
The im-. plication of the study is that a more realistic evaluation of the field-. measured permeability of a compacted clay soil may be possible in. the laboratory if the permeameter is sufficiently large to test a rep-. resentative sample of soil. KEY WORDS: compaction, permeability, waste disposal.
