Each spring, the Healthy Harbor Report Card is released. This report presents a summary of water quality scores and major restoration activities that took place throughout the prior year, and it monitors water health in four major water bodies: The Jones and Gwynns Falls streams, the Baltimore Harbor, and the Tidal Patapsco River.
The Healthy Harbor Report Card is produced in partnership with Blue Water Baltimore, and near-real time water quality scores can be found at HarborAlert.org.
WHAT ARE THE WATER QUALITY GRADES FOR THE BALTIMORE HARBOR?
FECAL BACTERIA: F
Fecal bacteria is a human health indicator. Bacteria measurements help us determine the risk of getting sick if someone comes into contact with the water. Common sources of bacteria include sewage overflows, broken sewer pipes, and pet waste.
CHLOROPHYLL a: F
Chlorophyll a tells us if there is too much algae in the water. Too much algae can lead to low dissolved oxygen, which can harm organisms living in Baltimore’s waters.
DISSOLVED OXYGEN: B
Dissolved oxygen is important for all organisms that live in the water. Fish, shellfish, and other life need oxygen to breathe and thrive.
TOTAL NITROGEN: F
Total nitrogen is a measure of a nutrient that tells us how much stormwater pollution is coming from the land. Common sources of nutrient pollution include fertilizers, waste water, urban runoff, and the burning of fossil fuels.
TOTAL PHOSPHORUS: F
Total phosphorus is a measure of a nutrient that tells us how much stormwater pollution is coming from the land. Common sources of nutrient pollution include fertilizers, waste water, urban runoff, and the burning of fossil fuels.
WATER CLARITY: F
Water clarity is important for fish and plants that live in the water. In order for fish to see and find their prey and for underwater plants to grow properly, the water needs to be clear.
