Normally, the tap water has so many dissolved gasses and salts that I can't see through it when it first comes out of the tap, but if you let the water sit for a minute or two the gas bubbles come to the top and it becomes transparent.   Also, it has so much dissolved salts that putting tap water in a pot and boiling off 20% of it leaves a visible precipitate/residue on the bottom of the pot.    This fucking sucks.   If you run the cold water for >5 minutes before filling up from it, it comes out clear.  But the excessive dissolved crap problem is still there.   You can't boil off 20% of it without forming a precipitate.   It probably isn't healthy to drink water that has so much dissolved crap in it.   I looked up their test results, which meet LEGAL limits but don't meet EPA health guidelines or California public health goals:
