Interesting. Two studies with pretty much conflicting conclusions about safety of copper for potable water. I imagine that there is a level (range) of exposure that is in the sweet spot between 'kills harmful microbes' and 'kills/harms humans who drink the water'.

One study is abut storing water in copper pots and the other is about copper in drinking water. Does storing water in pots automatically mean that the copper goes into the water and if yes, how high is the concentration?

#5The antibacterial properties of copper are well known, and were proven long ago. I think this is just someone looking for something to research and write a paper on.

I suspect that outcome depends on water pH and temperature. One doesn't use copper pots for cooking acidic tomato sauce, for example. Acidic well water corrodes copper plumbing.

Note that the authors of the paper being discussed are Indian. Literally any way of having potable water is better than what they do now.

Not surprising, there is no contradiction. Copper is toxic to many forms of life.

TFA looked at the copper concentration in the water after storage and it was below WHO guidelines for safe copper levels. Whether the WHO guidelines are sufficient or not is another question.

The WHO guideline for copper is 2mg/l which is the same as in the German guidelines "Trinkwasserverordnung". The article linked by batter says right in the abstract:
We found that the disease can even be caused by copper concentrations below the allowed concentration given by the German Guidelines for Drinking Water (Trinkwasserverordnung).
