URI Watershed Watch uses the USEPA approved membrane filtration method with mTEC media for analyzing fecal coliform and E. coli bacteria rather than the Rhode Island Department of Health approved MPN (Most Probable Number) procedure. Watershed Watch data is intended for screening purposes only, but is very valuable for targeting areas of concerns and for tracking potential sources of bacterial contamination.

Rhode Island standards for recreational contact:
Fresh water - Fecal coliform not to exceed 200 fecal coliform / 100 mL.
Marine water - Fecal coliform not to exceed 50 fecal coliform / 100 mL.

USEPA standards for recreational contact:
Fresh water - Recommends the use of E. coli, not to exceed 126 E. coli / 100 mL.
Marine water - Recommends the use of enterococci, not to exceed 35 enterococci / 100 mL.
(Enterococci data available upon request for a limited number of sites)

Narrow River sites #02 through #10 are considered marine water sites.
