Fecal Coliform Bacteria are bacteria found in the intestines of warm- and cold-blooded animals. Fecal coliform bacteria are not harmful, but do indicate that disease causing pathogens or disease-producing bacteria could be present. This dictates that the higher the fecal coliform concentration in a body of water, the greater potential health risks. Testing for fecal coliform bacteria is performed to determine the potential presence of these harmful pathogens and bacteria. Fecal material also can be responsible for low dissolved oxygen levels in streams. The decay of organic material by bacteria depletes the water of oxygen. This lowered oxygen level may kill fish or other aquatic life. This risk most often occurs when fecal coliform bacteria levels are very high, typically after storm runoff events.
Fecal coliform bacteria levels in High Island Creek are among the highest of all monitored streams in Minnesota. As of 2006 there were four reaches in High Island Creek Watershed listed on the 303d list of impaired waters. Monitoring data indicates frequent violations of the monthly fecal coliform standard. The magnitude of these violations, especially during the summer months, suggests serious water quality impairments that will need substantial bacterial reductions in water bodies.
