Water Quality Monitoring
NNWB supports three different stream water quality monitoring programs - all are welcome to voluntee
1. Anacostia Riverkeeper's (ARK) water quality testing program runs through the spring and summer. NNWB volunteers conduct testing at sites in Montgomery and Prince George's Counties. Volunteers are needed for sites in Montgomery and Prince George's Counties. This program measures e coli (bacteria), turbidity (cloudiness, such as from sediment), pH, dissolved oxygen (fish and zooplankton need this to breathe), temperature and specific conductivity. ARK posts the results on a map here.
2. NNWB volunteers test water for salt (via chloride levels) through the Izaak Walton League's Salt Watch program. Salt pollution is unfortunately common in cold-weather months when jurisdictions and residents use chloride-based ice melt. We test the water year round and after each snow or ice event. See data from our sites here. Contact us to get involved on NNWB's sites or establish a new test site near you.
3. We participate in Nature Forward's macroinvertebrate program (see photos and a description below). See how to participate here.
