http://www.swisswetter.ch/informationen/impressum.htmlhttp://www.swisswetter.ch/Wissen/chemtrails-regenwasserproben.htmlThe review of the "Basler Girls" by Swisswetter is unfortunately limited as the reference of the "Trinkwasserwerte Zürich" is not accesible. Therefore, the review can not be discussed.
Nevertheless, one has to have in mind that there is difference between a steady irrigation from above and aluminum in drinking water. Drinking water can be filtered by Osmosis. The air can only be filtered by a gas mask. And there is another difference between drinking water and the air: the size of the particles. To give an imagination about the problem, look to the picture below. These small particles settled on the blood cell show how these particles can get into the brain.
To give an fundamental review to the results of the "Basler Girls" it would be more profitable to all parties if professional measurements would be public. Unfortunately, professional measurements are only allowed if the law tell to do so. Voluntary measurements by professional are not accessible to the public. Even your "Trinkwasserwerte Zürich" you refer to can not be accessed.
To finish this review: bcws.ch is a limited company. Therefore, the opinion of this limited company is only of limited value, as it is only limited liable to the content of the website.
