This headline is not correct. The ruling was that a constitutional lawsuit was not successful, not that the the US government has carte blanche to poison its citizens drinking water…
So, the correct headline would be “safe drinking water ruled not to be covered by the US constitution”. There are other binding agreements and regulations than the constitution in the US.
