Starting in January 2011, the Center for Watershed Protection investigated outfalls in the Montgomery County part of Sligo Creek for illegal discharges by looking for flows in dry weather. On July 20th, Lori Lilly of the Center made a presentation at a Friends of Sligo Creek program meeting describing their findings and recommendations to the Montgomery County government.
The Friends of Sligo Creek Water Quality Committee encourages students and interested people to study Sligo Creek and share their findings. One way to do this is through science fair projects. Here are some science fair projects that have been done relating to Sligo Creek:
Sligo Creek vs. Sleepy Creek : This December 2004 study compares macroinvertebrates found in Sligo Creek with a creek in West Virginia. A science fair project by Theo Salem-Mackall, a fifth grader at Grace Episcopal Day School in Kensington.
It is widely recognized that among the problems facing Sligo Creek are sewer pipes adjacent to the creek leaking sewage into the water. Evidence for this can be seen in the Stream Corridor Assessment survey. The agency responsible for maintaining these sewer pipes is the Washington Suburban Sanitary Commission.
