better to pour the wash water from gum print to the ground than down the
drain?

Several years ago I read an article on the web (RIT site ?) about disposal of
dichromate waste. The article basically gave similar advice about converting
hexavalent chromium to the trivalent form and then pouring the waste water
into a bucket containing kitty litter, where the water is left to percolate
through or evaporate and the chromium binds to the clay. The soil is later
taken to a waste handler for disposal. Sounded good to me. Probably a good
way to manage the waste unless you are dumping 91,213 pounds of chromium
waste per day. I think I went through about 50 grams last year...
