Monitor Water Quality

Since 1995, CRWA has relied on volunteers to take water quality samples on a monthly basis along the Charles River as part of our Monthly Water Quality Monitoring Program. Sampling generally occurs on the third Tuesday of each month at 6am. Volunteers are fully trained by a CRWA staff member and all equipment is provided. Volunteers are asked to commit to at least twelve months of sampling.

Please keep in mind you may ask to be put on the waiting list for a site that is already filled. Additionally, CRWA is always in need of volunteers to be trained as substitutes, so even if sites in your area are full, there are always opportunities to assist with the program.

Interested individuals can contact Bryan Dore for more information or fill out CRWA's volunteer application form

Sample Benthic Macroinvertrates

CRWA seeks volunteers for the spring to conduct benthic macroinvertebrate sampling in the following communities:


Benthic macroinvertebrates are small aquatic organisms that live in the bottom substrates of lakes, streams, and rivers. The assemblage of these communities in our waterways provides an indicator of the biological health and integrity of the system.

Training dates will be in the spring. If you are interested in this opportunity, please contact Bryan Dore.
