Lead contamination

(NaturalNews) We've just finished testing the first 100 water samples we received from Natural News readers via our EPA Watch program to monitor the nation's municipal water supplies. Because the EPA knowingly lies about lead contamination in water -- and because state water testing agencies routinely commit scientific fraud to hide the truth about their water quality -- we have taken on the task of testing water for lead all across America.

Using our high-end analytical laboratory (CWClabs.com) and ICP-MS instrumentation running EPA methodology 200.8, we've just completed heavy metals testing the first 100 water samples we received. (Note: Heavy metals is just the first round of testing we'll be conducting. In another round, we'll be using the sample water samples to test for pesticides and other organic chemicals. Watch for that later...)

A full, detailed report of these water samples -- with details parts per billion results of the heavy metals detected in each water sample -- will be released here on Natural News within a week or so. Until that full report is released, here are some of the highlights of our ICP-MS analysis:

EPA Watch water testing results so far (heavy metals only)
• NONE of the water samples contained any mercury at all. Not even a single part per billion. This isn't a mistake. We are 100% certain that all these tested samples contain near-zero mercury. (Not surprising, as mercury is not commonly found in municipal water supplies.)



• Out of 100 water samples, over 95% were below the EPA's current lead limit of 15 parts per billion. We found one alarming sample with lead showing 700% higher than the EPA limit, and we found 2-3 other samples with lead at about half the EPA limit. (See below for details on the alarming sample we found.)

• Cadmium levels were consistently low, as was arsenic, across nearly all samples.

• We did find some evidence of copper contamination, with some samples as high as around 400 ppb copper. The EPA limit on copper is 1300 ppb, and we didn't find any water samples even close to that. Nevertheless, I wouldn't want to be drinking 400 ppb copper on a daily basis, so we will point out the copper problems in our detailed report.

• Total dissolved solids in the water varied widely, and we confirmed very high levels of strontium in many samples (over 1000 ppb). There's no danger in this, by the way. Strontium is a nutritive mineral that often appears alongside calcium.

Here's a look at some of the water vials we prepped for analysis:



We are calling for more water samples from North of Phoenix, in or near zip code 85086
The most alarming sample we found out of these first 100 tested was a sample from a small town about 40 miles north of Phoenix, Arizona. The water in this sample tested at around 115 ppb lead, easily about 100 times higher lead levels than most other samples tested.

Because these water samples are crowdsourced, we cannot rely on any definitive conclusions from a single sample. So we are asking all residents living north of Phoenix to send us more water samples so that we can build more data points and possibly gather evidence of a lead contamination problem in the water there.

With your help, we might be able to identify another Flint, Michigan type of situation before it harms more children. Our aim is to bypass the corruption and incompetence of the EPA and publish our test results directly to the public in an open source format.

What's next: Detailed report coming soon
The next step for us is to format all the detailed ppb data into a downloadable PDF for public release. I'm going to include the ICP-MS calibration curves for full disclosure, so you can see our relative standard deviations (RSDs) and other scientific details on the instrument run.

The good news in all this is that most of the water samples we tested were very low in heavy metals. Out of 100 samples, we only found one "alarming" sample, plus a couple of others that might deserve some caution.

The fact that we did not find mercury, cadmium or arsenic in any alarming quantities in any of these water samples is comforting. It shows that many cities are apparently doing an adequate job in keeping toxic heavy metals out of their water. However, we haven't yet conducted tests for pesticides, pharmaceuticals and other chemicals, so there could be many more surprises yet to come.

For now, we encourage Natural News readers to send us more samples so we can build a more complete map of results. We are doing this as a public service -- at no charge to you -- and sharing these results publicly for the entire world to see. This is truly open source citizen science being conducted in the public interest, bringing transparency to a realm that has been hidden in government secrecy and corruption.
