Yesterday I was able to go with some earth science students from Mountain Ridge Junior High to the mouth of American Fork Canyon.  The students were testing water quality and will be comparing their data to what is considered "healthy" for rivers.  Some of the tests they did: turbidity, dissolved oxygen, nitrate level, pH, and stream flow.  The weather was great and the students especially enjoyed getting in the river with waders on.
