The
Groundwater Flow Model is an educational device constructed
of sturdy layered sand lenses to represent a sliced section of earth.
Movement of water and contaminants are easily demonstrated to groups
of all ages. Through the use of water tinted with food coloring
or grape Kool-Aid, it is possible to observe a wide range of groundwater
movements and contaminaton events. The following are examples of
some of the actions demonstrated:
-
functioning
of tile drainage systems,
-
water
table fluctuations,
-
leaking
landfills and underground storage tanks,
-
movement
of water in artesian wells,
-
non-point
source leaching, and
-
stream
contamination.
