Metrowest Daily News 7/7/11: E.coli bacteria counts down at Mansion Beach in Wayland. The Wayland Surface Water Quality Committee received good news on Thursday morning from the Health Department regarding test results from a water sampling at Mansion Beach on July 5. Test results show E.coli counts at 68 — down from last week's 240, and well below the state's threshold of 235 for closing bathing beaches. "Whether attributable to good weather, the plastic coyotes, other goose counter-measures, or the dog and goose poop patrols, we're happy to see the situation improved," said Surface Water Quality Committee member Mike Lowery. The committee voted on Wednesday night to continue its E.coli sampling at various points in Dudley Pond during the 2011 season.
