Village Blue

Real-Time Water Quality Monitoring in the Baltimore Harbor

Mr. Trash Wheel Sensors were placed on the Jones Falls River near the Waterfront Partnership of Baltimore's Mr. Trash Wheel.Exit
The sensors gathered real-time water quality measurements for the Village Blue demonstration project.
EPA and the U.S. Geological Survey (USGS) initiated the Village Blue project to increase public awareness about local water quality in the Baltimore Harbor and the Chesapeake Bay. The project was conducted in Baltimore from 2017-2019. A new Village Blue site is currently under development in New Orleans to help communities better understand Lake Pontchartrain's water quality and its connection to the Mississippi River.

Village Blue Baltimore provided real-time water quality monitoring data to the Baltimore community and complemented work already being done toward the Waterfront Partnership of Baltimore's goal of making Baltimore Harbor swimmable and fishable by 2020.

EPA and USGS installed a monitoring site on the Jones Falls River near the Waterfront Partnership of Baltimore’s Mr. Trash Wheel, which captures trash before it enters the harbor. Village Blue built on EPA’s Village Green project, which provided real-time air quality information to communities in eight locations across the country.

What data were collected?

Village Blue’s water quality sensor station and Mr. Trash Wheel are both located on the Jones Falls River where it enters Baltimore Harbor.A USGS staff member reads data collected by the Village Blue water quality sensors.
 
Real-time water quality data were collected for the following:

  • Precipitation
  • Gage Height
  • Stream Velocity
  • Turbidity
  • Salinity
  • Dissolved Oxygen
  • Nitrate
  • Temperature
  • pH

Village Blue Baltimore's historic data can be downloaded and viewed on USGS's National Water Information System website.

How were data collected and where were the data displayed?

Aerial map showing the location of the Village Blue sensorsVillage Blue water quality sensors were located along the Jones Falls River, just upstream of Mr. Trash Wheel.To monitor water quality in the Jones Falls River and Inner Baltimore Harbor, data were collected in real-time by water sensors located underwater between the bridge and Mr. Trash Wheel. Multiple water sensors were connected to probes that record measurements of selected water quality parameters every five minutes. The monitoring site helped test, evaluate, and develop new water sensors that collect real-time water quality data.

What did Village Blue Baltimore accomplish?

Village Blue’s water quality sensor station and Mr. Trash Wheel were both located on the Jones Falls River where it enters Baltimore Harbor.Village Blue’s water quality sensor station was located on the Jones Falls River where it enters Baltimore Harbor.
 
Village Blue Baltimore’s monitoring data helped close water quality information gaps and gave citizens and professional scientists more data to inform communities, policies, and environmental restoration efforts.

The project worked to accomplish the following:

  • Provide important water quality information for Baltimore Harbor.
  • Support the development and test the accuracy of new water sensors.
  • Increase public awareness of water quality and ecosystem health through integration and visualization of real-time water quality data.
  • Produce an open source Village Blue data integration and visualization framework and how-to manual, which can be used locally and by other communities that want to develop their own Village Blue stations.

Water quality monitoring data can help communities take action to keep local watersheds healthy. Watersheds—the land areas that drain into streams, lakes, and rivers—directly impact the health of the water bodies and communities they surround. Learn more about the benefits of healthy watersheds.

  • Blue Water Baltimore Exit
    Blue Water Baltimore operates a large network of non-real-time monitoring sites in Baltimore. Blue Water Baltimore will be contributing to Village Blue’s data visualization and providing data to help scientists understand the Jones Falls River measurements.
  • City of Baltimore Exit
    The City of Baltimore has a network of non-real-time water quality monitors and is contributing to the data visualization and communication of the water quality data. View City of Baltimore’s water quality data. Exit
  • Maryland Department of Natural Resources (DNR)Exit
    The Maryland DNR has an extensive network of real-time and non-real-time water quality monitors and is contributing to Village Blue’s data visualization. Maryland water quality data and related information can found through the Eyes on the Bay website.Exit
  • Maryland Science CenterExit
    The Maryland Science Center interprets and distills the latest in scientific discovery for the public. They will assist in developing hands-on water sensor education opportunities.
  • National AquariumExit
    The National Aquarium opened in 1981 on Baltimore’s Inner Harbor and features educational displays on aquatic life in the Chesapeake Bay. The aquarium is contributing to Village Blue’s website content and data visualization, which includes real-time data collected near ships in the inner harbor. The aquarium will also help develop approaches to share Village Blue’s water quality information with the community.
  • U.S. Geological Survey (USGS)
    USGS provides operation and maintenance of Village Blue’s water sensors, data quality assurance, and access to water quality data through its water services program. USGS will also be contributing to Village Blue’s data visualization and sensor evaluation.
  • Waterfront Partnership of BaltimoreExit
    The Waterfront Partnership manages a Healthy Harbor Plan that focuses on reducing bacteria, stormwater runoff, and trash in the Baltimore Harbor. The Partnership installed the Baltimore Inner Harbor Water Wheel (Mr. Trash Wheel).Exit
