Water quality upstream

In this picture, we are getting ready to get our samples and compare them to readings other groups downstream were collecting.


In this picture, you can see where the water that is coming from the mining process that caused the water to turn brown.  Pyrite is the cause of the color change.  We measured the pH in both the brown area (it was 3.7) and in the green area ( it was 5.7).  Quite a difference!!
