We use perlite.

And another question... How long does it take you to build your aquifer? I find that it takes me approximately 30 seconds to actually build the aquifer, and I spend the rest of the time with my partner going over the concepts and generally just waiting. My presentations usually turn out pretty well, though. I don't see why other teams need 10 minutes to pile sand, clay, and gravel into their container... Am I doing something wrong or forgetting something?
well all pumping lowers the water table but the cone of depression makes a cone into the well like this picture

Does anyone know a good way to show remediation without using charcoal? I read on the side of the container that it was known to cause cancer so I guess that wouldbe hazardous. Any other ideas?

There are many many many ways to remediate water. Just think of a material you could add to water that you could easily get rid of through some kind of filter.

Good question. Erm, the only thing I can think of is having little lego trees near water.However, actually showing water getting sucked in through the roots and evaporate is going to be kind of hard.

If you take a funnel and experiment a little bit, you can generally make a pretty awesome filter. I would suggest using sand, paper towels and some small rocks.
