Enterococci are bacteria that are found in the GI tract of warm-blooded animals, which includes all birds and mammals.  Their presence in surface water indicates recent contamination with fecal waste.  Counts are expressed as cfu or colony-forming units.  Counts greater than 104/100 ml are shown in red as they indicate that water is not suitable for recreational use.
