The Friends of the Scarborough Marsh (FOSM) has completed an eight month water quality study of Mill Brook, a tributary of the Nonesuch River. The project, focusing on a 1.7 mile stretch of the creek running from Sawyer Road, under US Rte 1 to the Eastern Trail, aimed to identify constraints the town faces in improving water quality to levels that would permit reopening clam flats for harvest. Overall, water quality was good, with one major exception: coliform bacteria rated as poor at all four sampling sites during every month except January, 2012.
