Greetings Fellow Primates: Please correct me here, if I am wrong. But, I believe a household chemical, chlorine bleach, like Clorox, has a specific shelf life? (Not sure if I read that somewhere, some time ago - or, if someone told me that.) If so, have any of you good folk ever made your own chlorine bleach, as you needed it? I imagine the ingredients to make it, like caustic soda and soda ash, are not so limited? The idea of having to chlorinate our bore (well) in case of any introduction of bacteria from flood waters, or by other means, is what caused me to ponder this. Naturally, we will have the bore (well) drilled on the highest part of the property that we can. But, Mother Nature may have other plans.
