Re: Water purification
Agree a few microbes can kill you but unless you are getting your water from contaminated sources in the US not much of a concern. Infectious diarrhea remains a leading cause of childhood death worldwide but fairly rare here. Well water with clean pipes safe on land. Marina water should be looked at for source and plumbing but unusual to be a problem in US. Would be not as concerned especially if your water is used as sitting water more of a concern. You have billions upon billions of microbes on you and in you as you read this post including many potential pathogens. Still, proper handling of potable water is an issue of all of us on or off the boat. If your water sits by all means add bleach.
