Hop Brook Water Quality Study

Why does Hop Brook have some of the highest levels of nutrient pollution in the watershed?

Hop Brook in Sudbury is a major tributary of the Wild & Scenic Sudbury River. OARS’ monitoring of the Sudbury River found that levels of the nutrient phosphorus where Hop Brook enters are unusually high. The Hop Brook Protection Association has also been struggling to control nuisance algae and aquatic plants in the impoundments behind the three mill dams along Hop Brook, particularly Carding Mill Pond.

Tracking Bacteria Pollution in the Lower Concord River

For the last 2 years, OARS program to monitor E.coli, a fecal indicator bacteria, showed higher than acceptable levels in the Concord River at the Roger's Street bridge in Lowell. This summer, we undertook a study to track down the source.

Six intrepid volunteers collected water samples from sites upstream of the bridge every Monday morning for 15 weeks. We analyzed the data, narrowed down the possibilities of where the bacteria could be coming from, and adjusted the sampling sites accordingly.
