So, whats a Ramat Hasharon resident to do? Our water source is basically Taas' dumping place... And from acquaintances who work for Taas and the water company, I shouldn't approach our tap water with a 10 foot pole that has a uv lit brita filter on the edge...

I always get tap at restaurants, but at home, it's a bit scarier.

Good question Tal, from what I understand the water lines are monitored carefully. If a main gets tainted it is brought offline and a different source is used until the tainted source is cleaned. The only reason to worry about tap is if you are living in a building with bad piping.

Even if the water that comes out of the tap where you live is OK from a health standpoint, what about from a *taste* standpoint? I do generally drink iced tap water (in fact, massive quantities in this hot, hot summer) for financial reasons. But I buy bottled water occasionally because it tastes so much better. Like Jack, I am concerned about our aquifers, though, so lately I've been buying non-Israeli bottled water when I buy it. That's a strange feeling for a person who generally tries to buy blue & white!

Good point. I use filters for the taste factor as well... Unfortunately there are some companies which are not so good our country and it's probably better not to support them.

If you are really concerned, you can have your tap water tested by a chemistry lab. The health ministry has labs, and there are some private ones as well.
Filters are the most cost efficient way to go, especially if you install one under your sink or at the head of the water supply to your domicile. Activated carbon reduces chlorine and organic compounds, and other filters are available to remove nitrates and other ions.
Or you can let your tap water stand for a few hours to let the chlorine evaporate and then refrigerate. Remember that the chlorine protects us from waterborne pathogens/diseases like cholera.
