This week's bacteria data are in! 1 of our 26 sites had an elevated bacteria level above the EPA's safe swimming threshold (Douglas Nicholas Park at 135MPN/100mL). Remember you can view our monthly data at: https://www.wicomicoenvironment.org/wicomico-environment-news/river-updates
Thank you to our dedicated volunteers and community partners who make this monitoring possible!

The laboratory that analyzes our Creekwatchers samples for bacteria levels follows EPA’s standard protocols to determine if bacteria (enterococci) levels are safe for swimming. The threshold to determine that the sample meets acceptable swimming levels is 104 most probable number (MPN)/100 mL. While none of the Creekwatchers sample locations are public swimming sites, we publish these data when samples exceed the threshold to keep the public informed. Enterococci levels are an EPA-recommended indicator for risks to human health, but ultimately, each person is responsible for making the decision to swim in the Wicomico River watershed.
