  1. If it hasn't been said before: Please dispose of the bleach test separately from the other solutions. Dispose in a sink, flush with excess water, wait a while, then flush with more water before disposing of the other solutions.

It's unlikely the concentrations will be high enough to be an issue, but waste a few gallons of water just to be on the safe side.
