Aquifers come in two types which are shown below: unconfined and
Unconfined aquifers are those
into which water seeps from the ground surface directly
above the aquifer.
Confined aquifers are those in
which an impermeable dirt/rock
layer exists that prevents water from seeping into the aquifer
from the ground surface located directly above. Instead, water
seeps into confined aquifers from farther away where the impermeable
layer doesn't exist.
Which type do think is in more danger of contamination?
