Although the chemistry in this article may be a little daunting I recommend you read through it. The experiment seems well designed and I am anxious to see the results in next month's Part 2.

sorry, but what the hell did that article say?

[CarmieJo]

Basically it said that they are using very specific parameters in an experiment to see:
1) How much GAC is needed to remove impurity from a given volume of water
2) Given a steady flow and amount of impurity how long is GAC good for

The first case is when you medicate and then run GAC to remove the byproducts a couple days later. How much GAC do you need for this job?

The second would be a case where you run carbon all the time as a water polisher. How often should you change the GAC?

ok, I was looking for some results, but I guess there aren't any. cool. I thought I was going crazy.

The results will be published in Part 2 next month.
