Enough for it to be pumped out into a river ideally.
But generally enough of the toxins that it won't kill aerobic bacteria.

The major problem with landfill leachates are heavy metals.
You need to adsorb them onto fines, but then you still have the problem of how to prevent that escaping again as soon as you put that shit back into a landfill. And you also want to avoid creating monoliths so just sticking the whole lot in a massive cement block doesn't work too well.

I actually read about that today, it would be perfect.
But not cheap enough or have a high enough throughput.

Does simple evaporation concentrate the heavy metals?

(PsychoChomp, Fri 27 Jan 2012, 16:09, Reply)

It would do, but it would also lead to any volatiles being evaporated off with the water vapour.
There is an entire industry centred around the treatment of landfill leachate. You aren't the first to have tried this.

Yep, I've seen,
from the looks of it no one's got it quite right yet.

But with your extensive knowledge of spreadsheets, you're the man to come up with the solution?

I enjoy thinking about things, and trying to solve problems.
The end result is secondary to the process. Think of it as a form of mental masturbation, I don't see any problem with it.

I wasn't trying to be mean, I think it's good that you're thinking about it
It's quite an interesting topic. A lot of the leachate is just recirculated within the landfill to keep the temperature down.
