If you read The Intercept article, you'll see that the company was hired to test the water after the Flint water crisis began, in response to citizen complaints.
This is entirely separate from the federally mandated requirements around testing that was performed by government agencies.
> That municipal decisions played an important role too, is - if anything - an argument for the thesis that the water supply in the United States should not be trusted and not against it.
We arrived here in response to your misinformed claim that "A disaster like Flint could not happen here" because "Germany is closely monitored at the source, at the water works and even close to the user in apartment buildings and rental properties. Also, our water supply is not privatized, like in the US. A disaster like Flint could not happen here."
I've demonstrated that the US has similar policies in place, and neither the water supply nor the mandated testing for metals were privatized, yet the Flint disaster did happen. People and governments are fallible. Corruption and criminal negligence happens everywhere.
