This is the type of question most people might not think about, but I'm asking because my wife asked me. Where do you do you water testing? Since you need to rinse out the vials before and after each test, you need somewhere to pour that water. Do you do it at the kitchen sink, bathroom sink, utility sink, or somewhere else? Do you just pour the water down the drain, or is there a potential environmental concern?
