Clean Water.
Strong Communities.
Baltimore’s waterways connect our neighborhoods, our environment, and our future. Together, we’re monitoring water quality, restoring green spaces, and holding polluters accountable to build a healthier Baltimore for everyone.
Water Quality Report Card
How Healthy Are Baltimore’s Waterways?
We monitor streams, rivers, and the Harbor to better understand the health of our waterways—and the challenges they face.
Our 2025 Water Quality Report Card brings together data from 51 monitoring stations across the Baltimore region, helping residents understand local conditions and why clean water matters. A full breakdown of the data is available at BaltimoreWaterWatch.org.
Our Waterways Are Part of Everyday Baltimore
From the streams running through our neighborhoods to the rivers feeding the Harbor, Baltimore’s waterways connect us all.
But stormwater runoff, sewage, trash, and industrial pollution threaten the health of these places and the communities around them.
Blue Water Baltimore combines science, restoration, community education, and advocacy to address these challenges—and help build a future where clean water is a reality for every neighborhood.
Blue Water Baltimore takes a holistic approach to making safe, clean water a reality in Baltimore.
