Back in 2014, me and my best mate were suffering of very intense headaches. We thought it was just something casual and a coincidence, but It happened repeatedly so we started troubleshooting and realized it was caused from a water filtered tap in one of Perth's TAFE next to our classroom.
So ye, that little fountain was always overloaded of water, looked like due to service. Probably bacteria built up, filters weren't changed in a while and water was probably worst that straight tap water.
I have to confess, water in Perth, I believe in whole Australia, is very fresh and pleasant to drink. Due high standards of quality & control, we are very fortunate to enjoy a very good tap water. I drink it at work and at home, tastes better than most bottled waters.
Recently I red online (can't remember where exactly), where it was explained that bottled water, opposite from what we think, might be less healthy as water comes in contact with the plastic of the just produced plastic bottle. When tap water has been treated and brought to a very safe human consumption level. Just taste it by yourself, is sooooo delicious. I am out to drink some from the tap
