it has been tested. The water that comes from the spring is tested regularily becasue it comes out of all the drinking fountains in the park as well. Contamination from civilization I am not worried about because the water comes out of the cascades..no development to contaminate it.
Surface contamination I dont think is possible here becasue I get the water right at the source where it comes up from way deep underground. It does not sit in a large spot an pool..it bubbles up from the ground in the rocks and flows off into a stream right away.
