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.
