Hey, i went swimming the other day in a small river. About a month ago i volunteered to help do water quality tests on this river. One of the tests was colilert-18, which came to show an unsubstantial amount of bacteria in the water. However, the test only checks for 3 kinds of bacteria - one being e.coli.
Anyways, on our walk back we saw a sign that said swimming was prohibited since May 2006 because of bacteria. Now i am wondering what other kinds of bacteria could be present that would shut down the river to swimming? The water is flowing quite fast, the river is slightly rapid in some spots so there are no pools. It's remote, so not many bird or animal feces wind up in the river - at least that i expect.
Thanks,
Bryby
