Water Quality

The U.S. Environmental Protection Agency (EPA) did not release an Integrated Water Quality Report in 2024. This report is typically released every two years, but due to delays in data submissions and reviews at both the state and federal levels, the 2024 report has been postponed. The next full report is now expected as part of the 2026 Integrated Report cycle.  

Below we have provided the 2022 Integrated Water Quality Report as well as the Appendix B-1 List of Impaired Waters for Connecticut (EPA Category 5) and the Approval Documents for Connecticut 2022 303 (d) List.  

To help residents stay informed, check out the EPA’s "How’s My Waterway"—a user-friendly tool that provides information about the condition of local rivers, lakes, and streams using the latest available data from federal, state, and local sources.

According to the 2022 303(d) Impaired Waters List, there are no waterbodies within the Town of Granby currently identified as impaired or threatened that needs a TMDL restoration plan. However, the Salmon Brook (East and West Granby) are labeled as Impaired for Recreational purposes for E. Coli bacteria according to the EPA "How's My Waterway" website.
