Baltimore Harbor Waterkeeper
The Baltimore Harbor Waterkeeper uses science and the law to hold polluters accountable and to ensure that the government is upholding the Clean Water Act.
Our Baltimore Harbor Waterkeeper team focuses on protecting and restoring the tidal and nontidal waterways that flow into the Baltimore Harbor and the Patapsco River. We advocate for stronger enforcement of our laws for clean water, both locally in the Baltimore area and statewide.
Working hand in hand with our local community we amplify the voice of the people who are directly impacted by the top pollutants plaguing our City: trash, contaminated stormwater runoff, sewage, and toxics.

Water Quality Monitoring
The Baltimore Harbor Waterkeeper regularly collects data at 49 stations in the Gwynns Falls, Jones Falls, and tidal Patapsco River.
Baltimore’s waterways are a living resource, teeming with life and ecological importance. Blue Water Baltimore recognizes the biological, recreational, economic, social, and spiritual benefits of our waterways.
We keep a pulse on our waterways by routinely collecting and analyzing local water quality data from waterways across Baltimore City and County. This data supports our efforts advocate for better enforcement and compliance with water pollution laws. We also use data to keep our communities informed on water quality issues that could impact their health or neighborhoods.
