Friends of Sligo Creek’s Water Quality Monitoring program includes measurements designed to evaluate and track the Creek’s biological, physical, and chemical health. We post the results of these monitoring efforts here on our website (see below), and regularly share them with government agencies such as Montgomery County Department of Environmental Protection (DEP) and the Maryland-National Capital Park and Planning Commission (M-NCPPC, or Parks.)
Our Water Quality volunteer team conducts monthly sampling at seven sites along the Creek’s middle reach, measuring physical parameters like temperature, pH and conductivity, as well as pollutants like ammonia-N, Coliform and chlorine. See the Testing Parameters and Equipment table below for details on these parameters.
In the summer of 2020, we began sampling for turbidity, Coliform, and dissolved oxygen levels as part of a regional consortium, the ARK/FOSC Volunteer Water Quality Monitoring Program, led by Anacostia Riverkeeper (ARK). We’re partnering with ARK again in 2021.
In addition, we partner with the Audubon Naturalist Society (ANS) to help track Sligo’s biological state, keeping track of macro-invertebrates, insects, fish and other animals at our sampling sites on quarterly basis. This was suspended during the physical distancing restrictions in place during the pandemic.
Finally, our Water WatchDogs program allows citizens to report suspected water pollution or other unusual water quality issues directly to DEP and Friends of Sligo Creek via the Water WatchDogs reporting form and via [email protected].
