WSSC Water Quality Monitoring
Here are the Spring 2009 results of WSSC's fecal bacteria monitoring tests which are required by the consent decree. One Sligo Creek site was tied for the fifth most Enterococci bacteria of the 40 tested sites; the other had the twelfth most. These results are from this WSSC report.
