The “map above” shows the elevation of the water table in feet above sea level in wells
in the area of 2 farmhouses. Both of the farms use groundwater. A spill of toxic
chemicals (special sauce for Big Mac hamburgers) has occurred near farm house 1. Your
task is to determine if their groundwater is in danger of being contaminated by the spill.
To do this exercise, you must first contour the water table (use 10 foot contour lines) and
then draw flow lines to indicate the direction of groundwater flow. Do this on the map
and then answer these questions:
1) Do the residents living in farmhouse 2 have anything to fear in their groundwater from
the spill? Yes
No
2) Is the water safe for the residents of farmhouse 1?
Yes
No
