Excuse me, can I drink tap water from Laishan Shanghai Beach Garden in Yantai?

What tap water is this? Unqualified. Generally speaking, there will be no floating objects after disinfection, precipitation and filtration in waterworks. It could be something in the water pipe. However, as long as the water is boiled, you can drink it. If you think it is really impossible to install a filter at the entrance, its function is actually not so necessary. As for the scale, it is formed by precipitation after boiling some hard water containing calcium ions and magnesium ions, which is harmless to human body and will precipitate after boiling.
