If there is a single resource best monitored for contaminants it is drinking water. Having spent 30+ years working for a public water supply system I don’t see a problem here.
That is precisely why EPA wants to regulate. They are a solution in search of a problem......and therefore need to be disbanded.
“Contaminants”?
The human body absorbs strontium as if it were calcium. Due to the chemical similarity of the elements, the stable forms of strontium might not pose a significant health threat — in fact, the levels found naturally may actually be beneficial -Wiki
99% of drinking of drinking water an it poses a threat?
This is the nose of the camel b.s. .
Disband the EPA now!
If it is naturally occurring is it a contaminate? What is the cost of removal?
