This is not an official Broselow Tape. This is a modified, made-at-home looking generic tape. To the credit of the product it doesnt state that its the real-deal, but I didnt expect to get what I did. The strip I got is printed on what feels like printer paper, and will not hold up during any type of resuscitation attempt.
Confined aquifer: An aquifer that lies between two relatively impermeable rock layers. Confining bed or unit: A body of impermeable or distinctly less permeable material stratigraphically adjacent to one or more aquifers ...~ An aquifer that is bounded above and below by low permeability formations or aquitard s.onfined aquifer. Confined Aquifer. An aquifer in which ground water is confined under pressure which is significantly greater than atmospheric pressure. Source: Terms of the Environment ... Confined aquifer: Aquifers that are wedged between layers of relatively impermeable materials and are consequently under pressure.
The upper level of this saturated layer of an unconfined aquifer is called the water table or phreatic surface. Below the water table, where in general all pore spaces are saturated with water, is the phreatic zone. Substrate with low porosity that permits limited transmission of groundwater is known as an aquitard. An aquiclude is a substrate with porosity that is so low it is virtually impermeable to groundwater.
