Yeah, they are much tougher out east with regard to "toxic" waste 
removal and such. However, why not just let the chemicals evaporate 
(it's mostly water) which only leaves the solids which are much 
easier to dispose of.

Although, it seems to me that the instructions for Ferric Chloride 
disposal are to dump it down the drain.  If the instructions state 
that, I would have to assume it is safe to do so. Is it?
