How Stream Monitoring Works

group uses net to catch insects in streamWe train volunteers to assess ecological conditions in streams based on the presence and abundance of benthic macroinvertebratesĀ (aquatic insects). Volunteers also learn how to take chemical measurements about nitrate/nitrite and turbidity. Training includes indoor and field workshops and mentoring by experienced monitors.

The Northern Virginia Soil and Water Conservation District provides all the training and equipment you need. No prior experience is necessary. Volunteers can monitor at different levels of commitment. You may choose to assist other monitors when it is convenient for your schedule. Or you may adopt your chosen stream and commit to monitoring it four times a year. We will make the program work for you!

NVSWCD reviews and certifies the data and forwards it to the Fairfax County Stream Protection Strategy Program, Virginia Department of Environmental Quality, and Virginia Save Our Streams.
