Wisconsin Public Radio News: ‘Good News & Bad News in River Report’
There is good news and bad news for the upper Mississippi River. The good news is water quality has improved since the Clean Water Act was introduced 40 years ago and fish populations have diversified. The bad news is that sediment and phosphorous build up continue to be an issue, especially in Lake Pepin. New chemical compounds are being detected in the river, ones like triclosan. It is a chemical found in most anti-bacterial products and when it combines with chlorine or sunlight, it can produce dioxins.
