Below please find our Etowah River Bacteria Graph for Sept. 20. This week's geometric mean for our three testing sites was 25.6 cfu/100ml, below the EPA safe limit of 126 cfu/100ml.
Below is the data for each of our three monitoring sites:
| | 9/20/2011 Water Temp. 25 C |
| | 13.5 cfu/100ml |
| | 24.6 cfu/100ml |
| US 411 | 50.4 cfu/100ml |
| Geometric Mean: | 25.6 cfu/100ml |
Since CRBI began this testing program in March, the geometric mean of the three testing sites has been within "safe limits" in 22 of 26 monitoring events.
