[at-l] Trail Maintenance-Not AT Specific

[m_factor@hotmail.com (Mara Factor)]

Hmm...  showing my ignorance here...

I was part of an ATC/DOC/AMC group that installed a bunch of bog bridges in 
VT this spring.  We used pressure treated wood (no creosote).  We used 
pressure treated because untreated wood rots very quickly in boggy areas.

I can certainly understand about using caution when using creosote covered 
wood.  I'm wondering why pressure treated wood might be considered worse 
than railroad ties for bog bridges.  Are they infused with chemicals that 
can leach into the bogs?  More chemicals?  Different chemicals?  Easier 
leaching?  ?????

Inquiring, ignorant, and curious minds want to know...  :-)

Thanks,

P.S.  I just ordered that trail maintenance notebook but it'll take a few 
weeks 'til I get it...  Maybe THEN, I'll have all the answers...

  ;-)
