Does anyone have any information on the "do's and don'ts" of disposing darkroom chemicals (black and white...dev, stop, fix, selenium, etc.) down a septic system? I recall reading about this somewhere before, but I can't seem to remember where. (Perhaps an old issue of View Camera?) I have a friend who is building a large darkroom capable of producing 30x40 inch archival fiber-base black and white prints, so chemical dis posal is going to be a primary concern. Any comments? Thanks in advance.
