Riffle Bio Assessment by Volunteers (RBV)

Rapid Bio-Assessment Program Re Instituted in 2012 through a $10,000 Grant from the 3M Foundation.

Rapid Bio assessment (RBV) supports the QRWA’s volunteer monitoring and citizen science programs and helps the CT DEEP gather much-needed data to monitor the Q River’s environmental quality. The 3M Foundation is providing financial funding for the equipment and related support for this aquatic assessment. 3M has a production facility in Meriden on Research Parkway and is a major supplier of water filtration products. RBV does not test the water’s drinkability, but rather the quality of the ecological environment based on the type and amount of organisms in the water.

It is the intent of the QRWA 3M RBV program to provide the CT DEEP with the highest possible quality voucher samples from as many locations within the Quinnipiac River basin during the sampling events. We will provide training and practice opportunities to team leaders and their volunteers to ensure everyone understands the science behind the program, demonstrate the correct way to collect, identify and process the voucher samples and review safety guidelines.
We want everyday people who have an interest in the health of the Quinnipiac River to be able to participate in a positive, safe and fun learning opportunity as citizen scientists. Contact Becky Martorelli, RBV trainer, 203-213-4366 for more information or to volunteer.

October 2013 a $20,000 3M Environmental Education Grant was awarded to QRWA making it possible continue with RBV with area high schools and to introduce annual field trips that include water quality testing, chemical and physical testing of samples taken from Hanover Pond. Students also learned how to fish, fly-tie, kayak and they released the trout they raised in the classroom. Next year this event will be expanded to a full day.

On August 26th, 2016 Rebecca Martorelli became a CERTIFIED Local RBV Trainer 2016-2020. Thank you Becky for your commitment to this program and for your continued support to improve water quality in the watershed.

Rapid Bio- Assessment Update for Fall of 2012

In the fall of 2012 we were fortunate to engage Maloney High School Students in the process, rely on a core group of return volunteers, and offer community service hours to students that were previously trained. We have plans to expand our RBV throughout the towns/cities in the watershed. Please contact QRWA RBV Instructor and Trainer, Becky Martorelli if you wish to participate or become a Team Leader for our 2013 fall program.
