<DIV>Alex, </DIV>
<DIV> I know a piece of property well that would
benefit from this treatment. It would have been a city park by now if not
for a trace of arsenic, crankcase oil and diesel fuel. It was the old clean
hard filled gravel pit I used to work off of. I think much of the contamination
is leaching in from the neighbors property which was not filled so clean. The
property is for sale in prime territory. </DIV>

<DIV class=moz-cite-prefix>Dan,<BR>It is being studied widely. Everything from
pesticides, PCB's and miscelaneous hydrocarbons to specific heavy metals.
Biochar gets compared straight up with Granular Activated Carbons, with some
added agronomic benefits. That is where it could scale up in the near
term.<BR>Alex<BR><BR>On 20/01/2013 12:12 AM, <A class=moz-txt-link-abbreviated

<DIV>I wonder if anyone has tried to clean up contaminated land with
biochar? What effect would it have on heavy metals or oil based
contaminants? Lots of prime real estate worthless because of trace
contaminants. </DIV>
