If you take it to your local water dept or water dist. they will test it for free. But natural springs tend to be some of the cleanest water around. Usually coliform and e-coli free. Sometimes a little hard and generally the ph is around nuetral. Which is 7. Test it pretty quick, you may have some great, free water but sometimes these sources dry up in late summer and fall. I have a friend who is a water chemist and springs and artesian supply still supply alot of people in this country.
