Drinking tap water

Is it safe to drink the tap water here in the UAE? I have heard different things about Abu Dhabi, Dubai and Sharjah.

I would prefer to drink the tap water if possible, but I have been told of a number of possible risks.

Bottled water is much better.

Besides the risks of drinking tap water, the taste is awful, not to mention the side effects...

If you are insist to drink it, I advice you to boil a couple of minutes before consumption.
Using the water for cooking is not a problem.
