WSSC Analysis of Monitoring, December 2011
WSSC presented the results of their bacteria monitoring in area streams through 2011 (need link to the presentation). A preliminary qualitative observation is that 80-100% of the bacteria sources in area streams has been found to be from pets, wildlife, and agriculture, and the predominate source, avian/waterfowl. A note regarding the comment in slide 4: “Suggestions from AWS considered: reduce points outside the Anacostia watershed.” The complete suggestion was to reduce the sampling points and double the monitoring frequency at certain stations, leaving the actual number of times monitoring was done unchanged.

As a result of the consent decree, the Washington Suburban Sanitary Commission (WSSC) began monitoring regional waterways for levels of fecal bacteria, including bacteria source testing. Here are the results through 2016 for Sligo Creek:
2004-2005 Water Quality Testing
The Anacostia Watershed Society’s Water Quality Specialist Masaya Maeda conducted bacteria testing of Sligo Creek. This important work led to the WSSC’s present monitoring.
