Part Two: Do You Drink Tap Water?

Sun Aug 21, 2005 10:00 pm

I started a topic on tap water but was locked sometime ago.

I normally do except in places which tap water are not drinkable due to hygiene problem. Always in Canada, USA, Western Europe, Norway, Southern Europe, Australia, New Zealand etc and sometimes in Hong Kong when I am lazy (the water in Hong Kong is drinkable directly from the tap) though a small amount of chlorine/fluorine have been added to the water (Shouldn't be a problem). Go to: http://www.wsd.gov.hk/en/html/others/faq_wq.htm

So do you? And does the water in your home city contain chlorine and fluroline and stuffs like that? I know countries like Canada, Switzerland etc do not.....

In Athens the water is OK so I always drink from the tap. I also drank tap water when I lived in Essex, although it was pretty hard, leaving salts and limescale everywhere,

No way - my condo (rented now) has a built-in Culligan and now I buy spring water (a buck and some change at Shoppers). If I have to drink tap, I will, but I prefer having my own system, obviously due to all the chemicals that are irresponsibly dumped or just allowed to get into the system. I don't know if the problem will be fixed, ever, over here in the States. I don't know of a place in the U.S., either, where residents can be confident they can drink unpolluted water from the faucet.

Uh tap water nearly everywhere will contain cholorine. Tap water in most places will contain flourine, especially with the increase in tooth decay seen in the Western world.

Of course I drink tap water. Despite chemicals like chlorine and flourine, it's perfectly safe. To argue it's not, based on no empirical evidence, is similar to arguing that organic food is better for you - there's nothing to suggest it is.

The water in Hong Kong, Sydney and Singapore are drinkable but not tasty.

What does the water taste like in your home country?

this is actually quite true - tap water is actually cleaner (on paper anyway) than bottled natural spring water as while tap water is generally treated bottled water is not allowed to be treated and still be called natural.

In countries in Western Europe it at least is no problem, but it differs from community to community, it might be quite good in some place (like Zurich-downtown and up-lake) and so full of lime (in places like Glattbrugg near ZRH) that after a glass you need of calcium for a day or two is covered. In places like Egypt (and most of the Arab World) I would much advise against. You can use it for teeth-cleaning, but not much more. In case you HAD a glass due to having been thirsty, contact the nearest bar and ask for an Arak, dilute it with water and drink it, before embarking into other activities !

My water is from my own well and the level is presently about 170 feet (52 meters) down. It tastes exactly like the bottled water my wife was buying at Costco which was about the same price as gasoline.

We do use bottled, distilled water in our coffee maker though.

Went to a wedding reception last night. They ran out of bottled water early and still had tons of beer and wine left. Sign of the times.

I'm glad you are concerned about pollutants in drinking water, but you have to realize that risk assessments have been performed on hundreds of chemicals to establish acceptable levels of ingestion. Public water systems are required to analyze for over 80 anaytes in their source water and their distribution system. Other regulations require systems to look for other contaminants that may need to be regulated in the future.

Further, many bottled waters come from the very same source water as tap water which you don't want to drink. Problem is, the same laws that force public water systems to monitor are not in place for bottled water producers! So, have your perceptions, but at least base them on reality. Do some homework on this, and you might like your tap water a bit more than your bottled.

Germany has on of the highest standard for Tap water. The hygiene is a very important point. (Even they try to reduce the necessary amount of Chlorine, in Germany you taste almost no Chlorine in the Tap water.) Here in "Schwarzwald", we have mostly excellent Tap water. I drink it very frequently. In some regions here, the water is very healthy, has a lot of minerals and is even recommended by the doctors to drink it... from the Tap.

I've been drinking tap water since I was a kid walking around with my friends in the summer heat opening my neighbor's outdoor taps, never got sick in my life. I'm very picky on drinking and eating things that are clean and fresh, but I trust the water as it is 100% potable.

In Argentina the tap water all over the country is excellent, I'd say the best in Latin America. Even in the far north near the borders, with some exceptions, everyone drinks it safely. In Patagonia you can even drink the water from creeks. I've never heard of a foreigner getting sick from Argentine tap water, and foreigners eat loads of salads and iced drinks when visiting. Every guide book like Frommers, Fordors, Lonely Planet says tap water in the country is completely safe. Smart tourists know this, but many are ignorant of this and spend loads of money unnecesarily in bottled water (which is great too), but they could have used all that cash in other things...

Well, there is. It depends on how you use the term "bottled" water and what the source water is. Spring water is groundwater that is naturally filtered through rock, etc. It is susceptible to contamination as is all other groundwater. It tends to taste good because of the mineral content. Keep in mind, though, that the regulations for spring and other bottled waters, are not as strict as that for Public Water Suppliers.

Distilled water is likely to be purest; however, it generally tastes flat as the minerals are removed. Bottom line, be aware of the source of your bottled water. A spring in Elizabeth, NJ is probably not going to give you cleaner water than a Public Water Supplier in Augusta, ME, for example.

Filtered tap water will give you a level of protection, but be aware that the kinetics of desorption can be very rapid, and if the filter gets saturated, you might get a slug of contamination in your next glass. Also, some filters remove volatile organics (carbon) and others metals (ion exchange resins). Just know what you're removing, and what you are not.

I say all of this because as someone whose job it is to provide technical support to EPA for drinking water regulation, don't just listen to public perception of tap water vs. bottled water. Look at the science.

It is also very important to make sure that the tanks and the pipes are ok. Copper, plastic etc must be used for pipes and tanks must be kept clean from time to time. Otherwise the water might not be as safe as it is.

It is for Kiwi's, It can hospitalise a Pom but you build up resistance, we have a filter and when visitors stay we chuck in 10 grams of chlorine powder per 1,000 gallons and that works fine, we don't chlorinate as a matter of course for own use

How come there isn't any water supply? What happens if there is no/little rain?

Rural areas don't have a reticulated supply, as development occurs some decide not to go onto the mains, if you run out you buy a top-up from the tanker man for 140 bucks, if my family didn't visit every summer i would not need to top up ever, we get plenty of rain here but it teds to fall in heavy bursts, usually you will get a 6 week period in the summer of no rain, so you wash in the sea!!! (well not really but we do 2 minute showers)

I guess it's not like your rainwater is all polluted with airborne industrial waste like ours tends to be in North America, eh Jafa?

In my hometown the north side of the city gets its water out of Lake Superior and if I remember correctly it is only minimally filtered and lightly chlorinated. It was always very cold, which was really nice in the summer. The south side of the city's water supply is a lake up on top of a mountain. I think it was filtered even less. Neither source had fluoride in it, and when I worked for an insurance company I found out just how much of a difference that makes in dental problems - we'd load premiums by 15 or 20% if the group was in a community without fluoride in the water.

When I went to school in Southern Ontario, we had an outbreak of cryptosporidium. A lot of people got sick from that.

Cryptosporidium has been linked to many waterborne disease outbreaks, the most notable being in Milwaukee, Wisconsin, where 430,000 residents became ill, 105 of whom died. Closer to home, a 1993 outbreak in Kitchener-Waterloo resulted in an estimated 1000 persons becoming ill.

I would have agreed with you a few years ago but now I have one word for you: Walkerton. Our standards might be great, but when the province unloads responsibility for the water supply to morons who can't see further than their own pockets, bad things happen.

For those of you who are not familiar here's a link: http://archives.cbc.ca/IDD-1-70-1672/disasters_tragedies/walkerton/. Seven people died drinking tainted city water.

I use tap water for tea, although we have a reverse osmosis filter and I use water from that because it tastes so much better. We are on city well water, so the water is a bit hard. We also have a Brita filter and I use that to make stuff like lemonade. I drink bottled water, but really the only reason for this is that I just won't drink water from a glass. I find that if I have a bottle of water I will drink it and I can make sure I drink enough water.
But that was when I ruled the world

Roy, you may be a Rickenbacker specialist, but you're no biochemist.  Wink

Osmosis is the process of water molecules diffusing across a semi-permeable membrane to dilute a saline soultion. In nature, water with no salts wants to go dilute salty water. Not on a global scale necessarily, but on an individual scale.

Reverse osmosis is the process whereby water is removed from areas of high salinity, thereby increasing the salt concentration on that side of the membrane. It's the water that moves, not the salts or chemicals. It's all about the water.

Thus, reverse osmosis causes contaminants to be concentrated, and then they are eliminated from the system.

Where I live the tap water tastes like shit. I've drunk it a few times, but that was when I was too drunk to notice the fact that it tastes just like pool water with metal shavings added yuck . It many places in New Zealand, the tap water isn't as bad. The purest tap water I tried was in Christchurch (delivered naturally straight from the beautiful southern alps).

I regularly buy bottled water from the supermarket.

The purest tap water I tried was in Christchurch (delivered naturally straight from the beautiful southern alps).

Yes Christchurch has the best tap water in the world. Aquifer water from the Southern Alps naturally filtered underground. The water is so pure that it does not require any treatment whatsoever.

As Andz said above, our tap water is of very high quality. The only reason I buy and drink bottled water is for the variety of very delicious flavours that are available.

Well I have 2 houses. In London I will drink tap water. In my house in Bangkok the water is allegedly safe to drink but we have a water purifier that the water goes through first.

The Thai water tastes much better, but obviously it has been purified to take all the muck out of it

I drink tap water at home all the time.
Berlin water comes from deep wells (Berlin is literally built on 800 meters of sand and gravel, the wells are betwen 50 meters and 150 meters deep). It is quite hard though and, as it comes from the wells, contains iron and manganese salts. The iron and manganese gets removed by spraying the water in big towers in the water works, thereby oxydising the two metals into unsoluble compounds, which coagulate and are then removed in sand filters. AFAIK, sterilisation is done by exposure to UV rays.
Bacteriological samples are taken every hour. Berlin water works have chlorine equipment for emergencies, but usually don't have to use it because the water, as it comes from the wells, is clean enough to pass the very strict bateriological requirements. There was only one facility, where they chlorinated the water in Berlin, this facility was providing the water for the American military installations during the cold war and the American military insisted to have it taste of chlorine.

Cologne water comes AFAIK from two sources, a dam near Siegburg and wells along the river Rhine. Since it passes the stringent standards, it is also clean, but like Berlin water, it doesn't taste of chlorine.

Quoting United Airline (Reply 39):
Does reverse osmosis remove any nutrients?

Reverse Osmosis is used to reduce the amount of dissolved minerals. The result is "Purified Water" (as stated on the lable of the bottle). If the process is made with the correct equipment, it will result in pharmceutical-grade "Purified water" (according the relevant pharmacopoeias).

Bottled purified water usually is enriched with a small amount of minerals after reverse osmosis (purified water would have no taste at all). Also it is not recommended to drink very large quantities of water w/o any minerals in it, as the different osmotic pressures of purified water and the fluids in your body can have a negative effect on your health (so the official saying goes, but I wouldn´t care !).

I know Amway uses an infra-red system.

Never heard of a water-treatment system using infrared-radiation ? What is it supposed to do ?

Re: Treating water at central points:
If the water contains too much Calcium, it will produce a white crust on your heating devices (in a coffee-maker etc.).
I know, that the water treatment plant providing my household with water uses a chemical substance called EDTA (see bottom) to reduce the amount of dissolved Calcium (and Magnesium).
Also, usually Iron is removed from the water by simply pumping air through the water: The dissolved Iron gets oxidised by the Oxygen in the air and forms a brown precipitate (Fe2O3 - for the chemists among you); the oxidised Iron is removed from the water by pumping it through a sandfilter.

Adding Chlorine:
In Germany Chlorine usually is NOT added to tap-water. Usually, the water is treated with Ozone at the source and pumped into the pipes. Only if microbiological tests at a point-of-use reveal that a limit of microbial organisms is trpped, Chlorine will be added and the pipes will be flushed (continued until positive testing is reached).

Adding Fluorine:
Unfortunately it is not done everywhere, but I´d like to see it. It HAS positive effects of the health of your teeth; but using a tooth paste with fluorine in it can get you the same effect.

I hope this little "lecture" was not too boring ?!

P.S. EDTA = Ethylenediamine Tetraacetic Acid; in commercially availabe washing detergents it is often listed (or promoted) as TAED and serves the same purpose: prevent that calcium carbonates stick onto heating device of your washing machine ...

The EDTA takes the calcium and magnesium ions and forms with them soluble complex compounds, which don't leave residues.

I am thinking of whether or not I should buy a water filter that uses reverse osmosis. Any recommendations?

It kills the germs. There is also a filter in it that filters the water.

Ozone is much better than Chlorine I think. A pity that Hong Kong uses chlorine to sterilize the water. It is drinkable straight from the tap but it might not be healthy. Go to: http://www.wsd.gov.hk/en/html/others/faq_wq.htm

Fluorine causes no harm to one's health right? In Hong Kong we do have fluorine in the water.

I live in Melbourne and the tap water is fine where I live, no need to buy it, never heard that we export it though?
