Anacostia River water quality gets failing grade

The murky Anacostia River has received a failing grade in an annual rating of its water quality, and experts say it will take the better part of a century before the historic waterway is once again swimmable. A new report by the Anacostia Watershed Society graded sections along the river based on visibility, bacteria from human and animal waste, oxygen levels, chlorophyll and vegetation. The Maryland section received a B-minus, and two sections along the District’s waterfront received a C. Anything below an A is a failing mark.
