Fecal contamination is a concern in many waterways. A recent analysis found high levels of fecal bacteria in numerous locations. More than half of monitored spots had dangerous levels at some point over two years. This issue affects various bodies of water, including rivers and lakes.

The analysis was conducted by Environment Texas Research & Policy Center, which monitored many locations. Further details about the study's findings are available.

Some waterways with high levels of contamination are located in Texas, and the issue may pose health risks to people who swim in these areas.
