  • E. coli standard
  • E. coli standard:

Not to exceed 126 organisms per 100 milliliters as a geometric mean of not less than five samples representative of conditions within any calendar month, nor shall more than ten percent of all samples taken during any calendar month individually exceed 1,260 organisms per 100 milliliters. The standard applies only between April 1 and October 31. Water quality standard changed in 2008 from fecal coliform to E. coli

Remaining tasks in Phase I

Update database Analyze data – Mississippi River, tributaries Identify data gaps Develop monitoring plan (2010+) Monitoring guidance:

Data collection preference

At least 5 samples per calendar month, April through October

Data collection alternative

Aggregate data for a given month across year

Source Inventory Discussion

What is your geographic area? What are the bacteria sources in your area? Where are the hot-spots? Do you have suggestions

  • f how (data sources) to

quantify the bacteria sources in your geographic area?
