2010 West River Watershed Alliance
Bi-weekly E.coli Level Report
(Updated July 15, 2010)
* State of Vermont Standard = 77 Escherichia coli (E. coli) organisms per 100 ml. of water sample.
EPA’s National Standard = 235 E. coli organisms per 100 ml. of water sample.
E. coli is a species of fecal coliform bacteria found in fecal material
from humans and other warm-blooded animals.
EPA recommends E. coli as an indicator of health risk from water contact in recreational waters.
Elevated E.coli levels are most likely due to excessive rain prior to sampling.
Swim at your own discretion.
Please note that changes in river conditions will alter bacterial levels over time.
Testing results are provided as a public service by the West River Watershed Alliance (WRWA),
also known as Southeastern Vermont Watershed Alliance (SeVWA),
and is supported by State of VT’s LaRosa Environmental Testing Laboratory and
Connecticut River Watershed Council (CRWC).
E. coli information for State parks and Army Corps of Engineers facilities
is available through those agencies.
Contact Laurie Callahan, Program Coordinator (volunteer), with questions
or if you would like to volunteer for WRWA programs. 802-258-1877
