1. As you explore water absorption and percolation rates in different kinds of soil, what are your thoughts about how water could move oil pollution through sand, clay, humus or a mixture of these soil types?
2. Which type of soil (sand, clay or humus) absorbs or holds the most water? How might this affect the amount of oil that could reach ground water?
3. Look at your soil sample observation table and explain how the properties might determine how much water is held by each soil type.
