Frequently Asked Questions
No. An aquitard (e.g., sandy clay) allows very slow water transmission. An aquiclude (e.g., unfractured shale) has such low permeability it is considered a barrier for practical purposes, though technically it may transmit minute amounts.
Yes. A thick layer of unfractured shale or dense glacial till often functions as an aquiclude, confining a water-bearing sandstone aquifer below it.
No. It is a specialised technical term used almost exclusively in geology, hydrogeology, and environmental engineering.
