Seedygirl will tell you that should be ok for plant/charcoal survival?
Anyway, that's what evals are for? She's just finished processing a load of samples from my last big eval, which has nicely demonstrated that we won't be bothering to sample anything on the main job that doesn't have obvious charcoal or waterlogged...once she's managed to dig all the compacted clay out of her sirafs and settling tank....
