Fecal Monitoring Results

Unflushed Toilet:  268 Fecal Bacteria Colonies
Little Falls Branch: 195 Fecal Bacteria Colonies

As a result of a class action law suit, the Washington Suburban Sanitary Commission (WSSC)  is required to monitor the fecal count of all county creeks ( WSSC Consent Decree – Civil Action No. PJM-04-3679 ).  The Maryland State standards for safe water use are listed below the chart.  We can work together to clean up the creek by controlling polluted run-off.    Click here for Washington Post column on unflushed toilets and Bay bacterial levels!

Help Prevent High Fecal Levels

We can work together to clean up the creek by controlling polluted run-off.  After a rain, rainwater rushes over pavement and lawns and carries poop right into the creek.   Pick up after your dog.  Install rain gardens, pervious pavements, and native landscaping to let rain water run seep the ground instead of running into the creek.
