Can't say for sure about your soil, but I recently pulled some 4X4 PT (CCA)
fence posts that had been in the ground here for 8-9 years, and they showed
no visible deterioration. I understand that some PT wood now uses a
non-CCA treatment, and I don't know if it is comparably durable.
A much more serious problem is what happens above ground. I have had some
8' 4X4s that warped over almost a 30 degree arc in 6 months. There seems
to be a correlation between the presence of knots and the propensity to
warp, perhaps because of differential absorption of the waterproofing
compound.
