CRWA Volunteer Opportunities

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.

View Current Site Vacancies

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 Delilah Bethel for more information or fill out CRWA's volunteer application form

Sample Benthic Macroinvertebrates

Each summer, CRWA recruits volunteers to conduct benthic macroinvertebrate sampling and identificationVolunteers attend a training in our field sampling protocols in early summer or a training on identification techniques in September. 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.

Canoeing for Clean Water

Through the Charles River Watershed Association's Canoeing for Clean Water program, volunteers set out on the river in canoes and pull invasive water chestnuts for an extremely rewarding experience. Volunteers have a great time exploring the Charles while helping restore the river's natural ecosystems.
