Competitions in November are not that uncommon. I have heard of many states that have them.

How are you building your aquifer? It's possible it's just poorly designed compared to others than have been effective in the past...

Ohh that's not bad at all, November is really early to have an invitational anyway. Keep at it!

Don't sweat it. You have a lot of time to prepare, and it may not completely be your falt. Doing poorly is a lot better than winning. Studying what you don't know will lead you to even more things to learn, so you will be much more prepared by the next invite.

About how long until activated charcoal stops working because the pores fill up? I have about maybe a volume of 1 inch cubed of granular activated charcoal. I only tested it once with about 1 inch cubed water with food coloring, and then I used water to wash any remaining food coloring out.

I find that reusing the same charcoal again and again produces less desireable results, so I use fresh charcoal each time. I will fill a small cup 1/3 charcoal, 2/3 pollutant and stir for about a minute or so. If it's stopped fizzing, filter out charcoal before it leaves behind dust. You can wash it to remove the pollutant for reuse, but as I said, less effective, which is not what you want at a competition.

Thanks, I just didn't want to buy some more charcoal.

Ehh, I guess I can use beads instead to show remediation. We don't get any bonus points for filtering out anything fancy like food coloring.

Is the written test just key terms? If not what else do we need to know?

Of the one competition I've gone to, the written test was just vocabulary. I can't seem to think of anything else they could test you on in the written test, but the event coordinator might do something else.
