If I travel to the US (Let's say Los Angeles, Seattle and New York) how do I know if the tap water is safe to drink? In the EU I normally just ask a local. In Germany it's safe to drink but in the Czech Republic you might be better off drinking bottled water (last time I checked was ~10 years ago, sorry if it's changed).


Locals will also tell you vaccines will give you autism and wifi is making them sick so they need homeopathic medicine.

Better to go with facts over hearsay.

The EPA requires yearly water quality reports (called Consumer Confidence Reports) for all municipal water supplies in the United States. Specifically they are due by July 1st each year.

Those reports don't tell me whether the water coming out of my taps is contaminated.


Then you get your own water tested. Here they have lead testing kits to try and weed out the old problems with lead pipes and solder.


If I travel to Europe, how do I know if the local knows the water is safe to drink?

Unless you're in Flint, or a paranoiac, tap water in the US is safe. Period.

Flint's problem is not endemic, it was isolated. The article is really reaching - they cite 3 instances over ~15 years of problems in city water supplies. In 2 of the 3 cases it was caught and rectified quickly - Flint is the exception.


> Unless you're in Flint, or a paranoiac, tap water in the US is safe. Period.

Given the size of the United States that's a very brave statement. Water quality in Europe is typically measured on on commune level and even in countries like Austria which pride themselves for drinkable tap water there are incidents which cause tap water to not be drinkable at times.


The U.S. is huge but it's also filled with a lot of people and a lot of local governments, state governments, and of course a federal government.

If you want one independent source of proof that U.S. water is safe, consider that almost every U.S. child has blood work done on an annual basis. If elevated levels of lead are a problem, they would be detected at that time, as they were in Flint.


"almost every U.S. child has blood work done on an annual basis"

What? I hated needles as a kid. I think I would have remembered having my blood drawn once a year.

At http://www.mamapedia.com/article/how-often-do-children-get-r... , there are a lot of people who had never heard of routine bloodwork. At http://www.metroparent.com/daily/health-fitness/childrens-he... is a doctor talking about routine bloodwork for children, but only every other year after the age of 5.


Almost every US child has blood work done on an annual basis? For what? What are they looking for? Lead specifically?


If your child is seeing a peditrician on a regular basis they will almost certainly test for lead levels at age 1 or 2. They do not test for it or do other blood work routinely after than unless high levels are found.

I remember getting a finger stick almost every visit to the doctor as a kid, but that was just for cell counts and maybe sugar that they did in the office, not a full panel of tests.


Yes, this is what I meant but phrased it poorly above. I guess a better way to say it is that almost every child has had blood work done an annual basis. But it reads like kids get a full blood workup every year, which is not true.


I have a US child and I don't believe he's ever had blood work done.


No, blood work is not an annual event for most children in the US. It's quite rare, which is why one doctor started testing as many children as she could to confirm that they were seeing spikes in lead levels.


Lead in blood is always a problem. A few years back one in 35 children in the US had elevated lead levels.


In major cities in the US like the ones you name, it would be very unusual to doubt the safety of standard municipal tap water. In my home city, this is based upon my own reading of the annual water quality reports they put out. I filter a lot of my own drinking water for taste reasons, but it's un-necessary and I do not hesitate to drink from taps anywhere.

With the recent worries about BPA and other components of plastics, it's unclear if bottled water from plastic is safer than tap at the 99.9th percentile of paranoia. I don't know about exotic risks from bottled water in glass (radioactive Evian from Chernobyl?), but I assume they are there also.

Nonetheless, in my circle of friends, I do know people who drink bottled water because they think it's more pure. I also know people who don't use microwave ovens because of harmful radio waves, and others who do not use plastic containers or plastic-lined metal cans because of hormone disruptors in plastics. I think they're nuts, and they compensate by thinking I'm naive and complacent.


Why would you think they are nuts? Hormone disrupters in certain plastics and can liners are a real problem, backed by science.


A close friend was an entrepreneur and evangelist in this space. I looked into it around 2008 and could not justify a significant level of concern relative to other risks. (Although "nuts" may be too strong...should say, "excessively worried".)

Re. Czech Republic -- nothing has changed, in the sense that drinking tap water was perfectly safe ten years ago, as it is now.

I suppose that demonstrates the dangers of your "ask some local" approach :)

Though the safety of tap water in CZ is well known, and has been well known for decades, and any local would tell you as much. So I'm not sure where that came from. Perhaps some temporary local incident?

Even Google may be a safer source of information on tap water quality.


Odd, I'll ask my father why he thought it wasn't a good idea. Thanks.



It seems to be broken. Every city I enter gives me no results.


Not every city makes their reports available. Might need a FOIA request to get it.


The safe drinking water act requires water supplies to not only create reports but also distribute them to their customers. My water company mails them out, thats probably par for the course. Putting them online might be optional, but they have to distribute them to their customers.


A pretty good rule of thumb I've heard is that if there's huge multi-liter water bottles available in every supermarket, it's probably a good idea to not drink tap water. The smaller and fewer the water bottles, the better the tap water is.


Default to not drinking from taps directly. I live in Seattle. We only use tap water after filtering with a Brita Filter for drinking and cooking. When we are outside home, we either bring filtered water with us or buy bottled water. At restaurants, if in doubt we ask if water is directly from tap.

Since the flint lead news, I have been exploring how can I get my tap water tested on a routine.


> Default to not drink from taps directly

Why?? Tap water is highly regulated, and 1000 times cheaper than bottled water. It does not produce tons of plastic waste (much of which is not recycled). It does not leach possible carcinogens like BPA, DEHA, or BBP. Furthermore, much of the bottled water comes from municipal tap water!

The Mayo Clinic says that tap water and bottled water are about equally safe. If you can't trust top-notch doctors, who can you trust?

This myth about bottled water being better needs to stop.

Water quality is one aspect. The water delivery mechanism is another, often ignored, aspect.

Flint issue has more to do with delivery.


Why??

I don't carry my own water, but tap water served by many restaurants tastes absolutely awful. So that might be one reason why.


Did you find anything acceptable, regarding the testing?


Any results on the routine testing? Pointers?


Actually just a low tech method. Asked my wife who is on Board of Homeowners Association (HOA) to find out if HOA has done any testing in the past or would consider sending incoming city water supply samples for testing annually.



I'm going to go out on a limb and say that "use a laboratory" is not the most helpful piece of advice ever :)


Ridiculous. First off, evidence that Seattle water is unsafe?

Second, brita is useless http://www.naturalnews.com/046536_water_filters_heavy_metals...


I won't jump in on criticizing naturalnews. but:

To conduct the tests, we created a multi-element "spike" solution containing from 1300 ppb to 2300 ppb concentrations of each of the tested elements.

The EPA limit for lead is 15 ppb. So the test is 80-150x the limit. This is 4-8x what's been seen in Flint (up to 20x the limit).

It should not be surprising that these filters were overwhelmed.

Depending on which element is being tested.. this 1300-2300 represents significantly more than or less than EPA limits.

This was a very sloppy test.. and it would be difficult to draw conclusions from it.


I wouldn't trust that link. The end of the article contains a pitch for a dietary supplement, which is a giant red flag to me. The fact that the sidebar lists conspiracy theories such as "Obama is a sleeper agent" and "San Bernadino was a false-flag" is basically guilt by association.


you're using 'natural news' as a source? this is one of the worst sites on the internet, literally riddled with unproven BS.


From another poster

"Nassim Taleb taught me that the absence of known danger is not the same as safety."
