The question was raised about the use of pressure treated
wood corrupting the soil in an organic garden.
Pressure treated wood is usually treated with a chlorinated
phenol [rather nasty stuff] and/or with organic arsenic salts
[also nasty stuff]. These materials will leach into the soil
and they are problem materials. The various Certified Organic
Standards usually prohibit the use of pressure treated wood
in certified organic sites.
