SODIS according to my research does kill viruses as well as bacteria. See here and also here

You know as well as I do that during the whole Covid debate, the science showed that the virus will not survive in sunlight. UV will kill a virus on a surface, so it's just common sense that it will kill a virus in a clear container.

I used the term Purify, in the context of my original statement in terms of bacteria, and viruses. I never said "Will totally purify", meaning of chemicals.

This was my original statement: All you have to do to kill bacteria and virus in water is leave it in the direct sunlight for a day. Italicized word DIRECT added so you don't come back with, "but what if it's cloudy"

I was right about this statement, and you were wrong to claim that sunlight contributes to bacterial growth.

You say:

No, SODIS does not purify water in any meaningful way. Who I ask you is using irresponsible language?

There are two things one is primarily concerned with, that can kill you in water. One is chemicals, two is bacteria, and some viruses. I suppose one could choke to death on a stick, but if one is that stupid, good riddance. What kills people short term is not chemicals, it is the bugs, the bacteria mostly.

If SODIS is capable of removing bacteria, in other words the things that kill you in a water shortage situation, and a virus which may harm you longer term, how is that not MEANINGFUL?

Finally, this conversations is not personal to me. This exchange of opinions is what adults are suppose to do when they don't see eye to eye on something, so more power to you. If however you want to actually back up your statements using sound reasoning, and actual facts, it would probably help us to find common ground.
