Entero Count

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
Mean
close

Geometric Mean

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
close

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
close

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).

Enterococcus is an EPA-approved fecal contamination indicator.

Samples taken by community scientists and processed at Watershed Assessment Associates, using methods and study designs that are consistent with Riverkeeper’s Hudson River and Community Science programs.

 

SAMPLING PARTNERS

This program is a partnership of Rensselaar Land Trust and Riverkeeper. Sampling is coordinated by Rensselaer Land Trust. Samples are collected by local residents. Samples are processed at Watershed Assessment Associates.
