More than half of Austin waterways have unsafe levels of fecal bacteria, according to a study out today. The analysis from Environment Texas found 46 of the 76 sites tested in Austin exceeded safe levels of bacteria at least once last year. 

Brian Zabcik, a clean water advocate with Environment Texas, said nearly half of the 1,450 freshwater sites tested across the state had similar problems.

"Of those locations, 49 percent had at least one day of unsafe bacteria level last year," Zabcik said, "bacteria levels that were too high to safely go swimming."
