I'm curious how folks dispose of their water samples after testing with the liquid test kits. I have a TF-100 test kit and noticed the warning labels on every bottle, mostly warning against contact with skin or clothing. Is it safe to be throwing my tested samples down the kitchen drain - into a septic system?
I realize there are minor amounts of each reagent used during each test, but I'm concerned about the cumulative effect after weeks of dumping test samples down the drain. Is this safe for my septic system?
