1 Real-Time Monitoring Buoy in Mystic River Watershed Access to the data has been through a password protected site Project Assistance: Liz McCarthy Laura Senefeld Matt Destino Tim Bridges Dick Siscanaw

2 Charles and Mystic River Real-Time Monitoring EPA New England Regional Laboratory The Real-Time Monitoring Buoys are off-line for the season Purpose: Environmental Protection Agency (EPA) has established monitoring buoys in the Charles and Mystic Watersheds. These buoys collect and transmit water quality data that is available to the public. EPA has established these buoys to help with the tracking of cyanobacteria blooms and water quality conditions. Note: All water quality measurements are collected 1 meter below the water's surface Last Sonde Verification: 9/3/21 Click here Project Partners: Disclaimer: The data presented on this website is considered preliminary data and may be subject to future revision or qualifiers. The data from this site is transmitted directly from the instrument with no or little review. Inaccuracies may be presented because instrument malfunction or physical changes at buoy location.

14 Summary of Use and Results Evaluation user feedback was positive Most interest in tracking cyanobacteria blooms Relocating Mystic Buoy Good probe performance against calibration standards Chlorophyll probe correlated poorly with laboratory Chlorophyll a method Phycocyanin correlated good with DPH Lab and Roger Frymire but poorly with EPA contract lab.

15 Next steps for RTM Buoy Project Finalize and report out the validated data Plan on deploying again in the Mystic and Charles next summer Find a new location for the Mystic Buoy Investigate different calibration methods for chlorophyll and phycocyanin Cultured cells for phycocyanin Investigate Public website
