Oddly enough, in the near future there might be an easy way around this. While chlorine is typically used as a water sanitizer, oxygen works just as well, and a new form of electrolysis may use a small current to produce enough oxygen to thoroughly sanitize water.
The US Olympic Swimming Team uses an oxygen sanitized pool because it has fewer negative effects than does chlorine.
I read several years ago that hospitals in France use Oxygen in the form of ozone to sanitize their laundry etc.
Then there’s beer. It got humans through the 15,16,17,1800’s. And more :)
I think you mean Ozone, it’s a damn good oxidizer for organics.
