ShoreRivers is pleased to announce its Swimmable ShoreRivers bacteria testing program will return for the season on Thursday, May 22, and that weekly results from this annual program will once again be available this year in both English and Spanish.
Every summer, ShoreRivers deploys a team of community scientists to monitor bacteria levels at popular swimming and boating sites to provide important human health risk information to the public. Their samples are then processed, according to standard scientific protocols, in ShoreRivers in-house labs. The program follows the Environmental Protection Agency’s standard protocols for collecting and analyzing samples and makes public the results of that testing to let people know about current bacteria levels as they make their plans for recreating in our waterways. Results are posted every Friday, between Memorial Day and Labor Day, at shorerivers.org/swim and on both the organization’s and its individual Riverkeepers’ social media pages.
A second page, shorerivers.org/swimmable-shorerivers-espanol, is designed to share this program with the Spanish-speaking community, and bilingual signs can be found at public monitoring sites around the Eastern Shore that explain the goals of the Swimmable ShoreRivers program and show users where to find weekly results in both English and Spanish. These signs (and the program at large) are made possible thanks to funding from the Cornell Douglas Foundation.
Weekly results are also shared on theswimguide.org, where descriptions of testing sites are available in both languages. This public service is a true community effort: this summer, nearly 70 SwimTesters will monitor 54 sites on the Choptank, Miles, Wye, Chester, and Sassafras rivers; Eastern Bay; and the Bayside Creeks. Special thanks go to our generous site sponsors, who include towns, marinas, homeowners’ associations, and families.
The Swimmable ShoreRivers program serves our community in a way that no other program, organization, agency, or data set does. In Maryland, if the state or local government designates an area as a swimming beach, then bacteria monitoring and reporting is required. However, a major gap exists on the Eastern Shore as very few areas are designated swimming beaches, and the results from those that are, are rarely posted publicly or in a timely manner.
“We work with our local community every day, and we know they’re interacting with our rivers in dozens of locations from Dorchester to Cecil County,” says Matt Pluta, Director of Riverkeeper Programs at ShoreRivers. “It’s our goal to make sure those individuals have available to them the information they need to know — namely, whether the water is safe for them to recreate in from a bacteria pollution standpoint. Swimmable ShoreRivers strives to enhance physical access to our local rivers, as well as access to data and information to help our community make informed decisions about how, when, and where we choose to enjoy our incredible natural resources.”
Also returning for the 2025 season is ShoreRivers’ Pumpout Boat. The Pumpout Boat is a free service offered on the Miles and Wye rivers that docks at the Chesapeake Bay Maritime Museum in St. Michaels and operates from May to mid-November. Through this service, we’re ensuring that every boater on the Miles and Wye has the means to safely and properly pump out — we can all help to keep marine waste out of our waterways. To schedule a pump out, contact Captain John Carlsson at 410.829.4352, on VHF Channel 9, by emailing POBCaptJohn@gmail.com, or by using the form at shorerivers.org/programs/pumpout-boat.
ShoreRivers protects Maryland’s Eastern Shore waterways through science-based advocacy, restoration, education, and engagement.
