HOW LONG DOES IT TAKE POLLUTION TO GO THROUGH SANDY SOILS?
The New Jersey Pinelands has very sandy soils. Under the soil is a vast underground water supply named the Cohansey Aquifer. Pollution of the aquifer can happen if people are not careful about how they dispose of oil, pesticides, or other things that we use. This experiment will show you how fast pollution can enter the aquifer. After you try it with sand, use some soil that is not sandy and you should see a difference.
