Enterococcus (“Entero”) is a fecal indicating bacterium that lives in the intestines of humans and other warm-blooded animals.
| [i] 4 Days Total Rain (in)|
4 Days Total Rain (in)
The combined rainfall for the day of sampling, prior day, two days prior and three days prior. More than 1/4 inch is considered a “wet weather sample.”
| [i] Number of Samples|
Number of Samples
Total number of samples included in these calculations.
| [i] Geometric|
A measure of central tendency (a weighted average) used by NYS DEC and the US EPA to assess water quality. The geometric mean is defined as the nth root (where n is the number of samples) of the product of the Enterococcus measurements. A geometric mean over 30 fails the EPA criteria for safe primary contact.
| [i] Maximum|
The highest Enterococcus count we have recorded at this site (“>” indicates an unknown number greater than this number and reflects the upper limit of our scoring ability for this sample).
| [i] Minimum|
The lowest Enterococcus count we have recorded at this site (“<” indicates an unknown number less than this number and reflects the lower limit of our scoring ability for this sample).
Note: multiple counts of the same value will overlap and appear as one dot.
Enterococcus is an EPA-approved fecal contamination indicator.
Rainfall data comes from wunderground.com. Wet weather is a common trigger of fecal contamination.
Water Quality scoring is based on the 2012 Recreational Water Quality Criteria from the US Environmental Protection Agency (EPA) for safe swimming. Learn More
