Bacteria Monitoring Results


Operation Clearwater:

During the summer, we monitor bacteria levels at various community waterfront and restoration areas as part of our Operation Clearwater program. Operation Clearwater was started by the Severn River Association and is a collaborative effort with Dr. Tammy Domanski, a Professor of Biology at Anne Arundel Community College, aimed at providing timely public health information to participating communities and helping to identify times when it may be inadvisable to swim. Knowledge is key in our fight for healthier, clean waters. In 2019, a 16 week schedule costs $465 and runs from May 22nd through September 4th.

If you are interested in having your personal or community waterfront tested, please contact

Bacteria Results for this season are listed below. You can also check out this data on our interactive web map. (This site is currently in the process of being updated).

West/Rhode Bacteria Monitoring:

At various locations on the West and Rhode rivers, we take bacteria samples to keep tabs on the health of the rivers. Many of our sites are near popular swimming areas, so results have the added benefit of being useful for residents when determining whether or not it is safe to swim in the water. This is a weekly program that occurs in tandem with regular tidal monitoring for other parameters.
