Tracking Bacteria Pollution in the Lower Concord River
| Over the last four years, OARS’ program to monitor E. coli, a fecal indicator bacteria, has consistently shown higher than acceptable levels in the Concord River at the Roger's Street bridge in Lowell. In 2020 we conducted a study that identified River Meadow Brook as the likely source of this bacterial pollution. Between 2020 and 2022, with funding support from the Greater Lowell Community Foundation, we have been intensively studying River Meadow Brook to track down the sources of the bacterial pollution. |
