actually i got problems at work too!
the water is very murky... even the bathroom's water.... i thought someone forgot to flush again....
and even my coworkers say the water they use for coffee that is from the tap is ALSO very mucky and taste funny...
So even you boil the water, it doesn't help because u just killed the bacterias in the water BUT it doesn't help the fact that all the substances in the water is still there.... so it's better to drink those bottled water....
