Benthic Macroinvertebrate Surveys
Loudoun Wildlife has been conducting benthic macroinvertebrate surveys around the county since 1996. We submit our survey data to Virginia Save Our Streams (VA SOS), a program administered by the Izaak Walton League of America (IWLA). VA SOS then approves and aggregates the data for the state and submits it to the Virginia Department of Environmental Quality, which in turn uses the information to identify impaired streams to target for further monitoring, habitat restoration and pollution control efforts.
Loudoun Wildlife is a partner with IWLA’s Clean Water Hub, where all our biological and chemical data are accessible by individual sites. If you are interested in viewing this data, click on “Explore the Map” and type in “Loudoun Wildlife Conservancy” in the search by organization field.
