A quick search on google yeilded these results:

Norit is activated carbon. I have no idea if you can use it to detoxify
soil.

Zeolite is an odor eliminator?

As I understand it, treated wood toxins leach into the soil with rain and
watering. When I was reading about treated lumber some time back, I was
amazed to learn that there are certain kinds of plants you can get that will
detox the soil. When the plants are grown, you pull them up and send them
back to the company that dispenses them so they can dispose of them properly
because the plants then have the bad chemicals in them. (Unfortunately I
can't remember what the company's name is or the name of the plant.) If you
can't detox the soil, I would suggest replacing it, or only growing
ornamentals in that spot. You wouldn't want to continue eating the poisons.

Here is a fact sheet on some of the risks associated with pressure treated
lumber

I initially built my raised vegetable garden with treated lumber. I
know, I know... please save your darts; I am already wounded and
require no additional flogging. I read multiple sources that said it
was okay, but in retrospect the only ones I recall that okayed it were
the government and the companies that produce treated lumber.
Everyone else says it's not worth the risk (or much harsher things).

So, that said, my garden has been around about two years. I'm going
to replace the wood borders this weekend (if anyone has a
cost-effective alternative, I'm all ears -- I like the pastic lumber
but can't find anyone that sells it in the Dallas-Fort Worth area),
but my next question is regarding the soil. Is it tainted, or can it
be salvaged? It's good stuff, too.

A local expert here says its possible to 'detox' the soil with
something called NORIT (also mentions something called zeolite), but I
don't know:

1. What that is
2. Where to get it
3. Will that really work, or should I toss the soil along the border
and start anew?

Also, depending on the cost, it may actually be more cost effective to
remove the [potentially] tainted soil and start anew.

I'm really bummed. I've been eating these vegetables for two years...

Thanks,
Chris
