If you have enough money, you can take some water you want to know about and send it to the local water quality testing department, usually in the provincial capital or the local big city!
See what water you are testing.
First of all, we can consider: Centers for Disease Control and Prevention,
The water testing center and water quality testing center are not open to the public.
Why not consider testing institutions in society. In society, qualification is a problem, which needs attention!
Hope to adopt! ! ! !
