Save The River’s Beach Watch program aims to test the water quality of eight local beaches and popular swimming destinations to ensure a safe swimming environment. Water quality is monitored by testing the levels of E. coli bacteria, which in high amounts can cause illness. E. coli is a common indicator used for testing of fecal contamination in waterways and is the recommended indicator in fresh waterways. Results are expressed in the number of bacteria colonies found in a 100 milliliter (ml) sample of swimming water. The New York State Health Department has set a swimming water quality limit of 235 colonies of E. coli bacteria per 100 milliliters of water for a one-time sample and 126 colonies for an average result over five weeks.
This year marks the 24th season of Save The River’s Beach Watch program. With the help of volunteers, eight swimming locations are tested every Monday for nine weeks from July 1 through August 30. The eight testing sites are: Frink Park, Clayton; Scenic View Park, Alexandria Bay; Thousand Islands Park Cove, Wellesley Island; Lake of the Isles, Wellesley Island; Wilson’s Beach, Cape Vincent; Round Island, Clayton; Potters Beach, Grindstone Island; and Sawmill Bay, Cape Vincent. Weekly monitoring results are posted on Save The River’s website (www.savetheriver.org) and social media, at their 409 Riverside Drive, Clayton storefront, and on the Swim Guide mobile app and website (theswimguide.org).
The Week 2 Beach Watch results from July 17, 2023 showed that five of six locations that submitted samples passed: Frink Park, Scenic View Park, TI Park Cove, Round Island, and Sawmill Bay had acceptable swimming water quality standards below 235 colonies per 100 ml sample. Wilson’s Beach failed the initial test but passed the retest on July 19, 2023. Potters Beach and Lake of the Isles were not sampled this week.
If a New York State swimming beach fails a water quality sample, the beach will close until it passes a resample test. Save The River monitors the Beach Watch program on a volunteer basis and has no authority to close the swimming areas we sample. The results are used to highlight areas of concern and inform landowners and stakeholders of potential health risks. When there is a situation of high bacteria, Save The River submits those results to local and state authorities for their use and action.
Beach Watch Volunteers collect samples on Monday morning. If you would like to learn more about this volunteer opportunity, contact Lauren Eggleston at firstname.lastname@example.org.
