River Prairie Group monitors the water quality of three rivers in DuPage
county - Salt Creek and the east/west branches of the DuPage River - as part
of Sierra Club's national Water Sentinels project. Volunteer collectors
retrieve water samples from regular intervals along the rivers and hand them
off to volunteer testers, who analyze them for phosphorus, nitrate, ammonia,
and chloride via spectrophotometric titration.
The data is then compiled into spreadsheets to determine the rivers' overall
pattern of water quality, and then posted on our website for public access.
Our data has been utilized by the media, educators, local and state policymakers,
researchers, and other volunteer river monitoring groups. As such, the Sierra
Club facilitates public education, while working with government agencies to adopt
environmental policies that will lead to cleaner river systems in the greater
The River Monitoring program is 100% volunteer staffed! So, if you are interested in contributing
to cleaner river systems in DuPage County, please consider joining us.
