This is a mainstem Sligo Creek site monitored for water quality monthly by Friends of Sligo Creek.

The Anacostia River is designated as a Class A waterway, which means primary contact, however the DC Department of Health (DOH) bans swimming in the Anacostia due to sewage overflows. The risk of high bacteria levels after a heavy rain storm is the only reason it is considered “unsafe” to swim in the river. The activation of the Clean Rivers Project on the Anacostia River is expected to prevent 80% of sewer overflow volume, getting us significantly closer to a swimmable river 365 days a year.
