Where is the threefold rat hiding? (II) - Guru's favourite fountain

We continue today our series of revelations of the Paris locations by presenting the spring from which Gregorian Bivolaru is supplied.

It is well known that Gregorian Bivolaru was not fond of drinking tap water even when he was in Romania and often recommended cures with spring water, this "mysterious elixir of life".
He was brought water from various springs even when in camps.
The same thing is apparently still practised today, but in France.

In Paris, there are many public water faucets and fountains. However, only 3 fountains in the city have natural water, drawn from deep in the Albien water table of the Paris basin. These are the springs in Place Verlaine (13th Arrondissement), Place Lamartine (16th Arrondissement) and Place de la Madone (18th Arrondissement).

Few people know that Nikolay Petrov, the MISA guru, is regularly supplied with water from the spring in Place Verlaine, which is only a stone's throw from the Square Dunois apartments.

It is at this fountain that the guru's close confidants can be spotted, who come once a week with a van full of empty plastic jugs to fill up.

Well, how's that, Grieg? You waste money on fuel to get this "sui-generis life-giving water" straight from the source and then "poison" it by keeping it in plastic? Is that possible, mon cher?

Already in 2017 the MISA website warned in an article (copied mot à mot  from the newspaper Adevărul) that keeping water in reused plastic containers poses great health risks. (Link Archive)  

Furthermore, how "is it necessary" to understand this "coincidence"? Born on the 13th, apartments in the 13th Arrondissment and favorite water faucet also in the 13th Arrondissment. What more surprises can we expect?
