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.
When a well is drilled into a confined aquifer, the water that is under pressure in it will rise in the well casing and may reach the surface. Wells with water flowing to the surface are often called free-flowing artesian wells. In most cases, wells drilled into artesian aquifers do not flow. Unconfined. An unconfined aquifer is a layer of water that has a confining layer on the bottom and a layer of permeable soil above it. The recharge are is all of the land area above the unconfined aquifer. The water level in wells drilled into an unconfined aquifer will be at the same elevation as the water table.
