is there a specific topic we need to study on? (like hydrologic cycle, groundwater, aquifers, vocab.)

Hydrology.

If you're just starting off, learn (as quickly as possible) the terms associated with the mini-glossary from the Groundwater Foundation, and then graduate yourself to harder terminology on their large Glossary. If you're in Dynamic Planet, you will see some overlap.

...and someone is bound to tell you check out the wiki. You're free to go there, too, but the Groundwater Foundation Awesome Aquifers page has everything.

If you are contaminating your aquifer with food coloring, I've found that it is really hard to get out. We use cool-aid, and then after we put the cool-aid in we make it "precipitate" so that the water makes the contaminant soak into the aquifer. I hope that helps:)

I'm not sure if cool-aid will work with sand, since we use gravel in our aquifer. I would assume that it would work, but i would suggest trying it before you walk into a competition:)

I never use sand, because it is very difficult to remove contaminants from. Leachate is the removed contaminant that is to be remediated. I recommend keeping it simple. Confusing the judges with big words used incorrectly will never help. (Kool-Aid is messy too). A lot of previous posts include remediation techniques too.

Wow, Churchill must be rich, we just throw away the sand and gravel after

Although this may be true, I don't think sand and gravel cost a lot

I hope when you "throw away" your sand and gravel you put it outside, not in the garbage. Lousy karma if you put rocks in the garbage.....

what sort of things do we have to include in our model

Whatever things you need to show the terms and concepts at Station 4...I would start with some permeable strata and work from there.

You should be able to demonstrate pretty much all of this:
