Details of the water quality monitoring program, and a detailed description of the methodologies used can be found in the Stormwater Collaborative's 2023 Quality Assurance Program Plan (QAPP). Our monitoring guidelines are at this link: Monitoring-Guidelines-Rev7-08-15-23final.pdf

In July 2018, the Buzzards Bay NEP issued a report, Lessons learned in the implementation of the Buzzards Bay Stormwater Collaborative effort to map and monitor stormwater discharges [updated in 2019], describing successes and challenges faced during implementation of the project.

Updated original Water Quality Data Reports

In the fall of 2023, the NEP updated the discharge reports for each of the eight stormwater collaborative municipalities. Below are the latest reports. These reports included stormwater quality data, dry weather inspection information, maps based on collected stormwater infrastructure GIS data, identification of possible illicit connections, and recommended priorities for municipal action to manage these stormwater discharges. Check the interactive map to see if there is more recent information for a particular site.
