GIS Mapping
At Potomac Riverkeeper Network, we are constantly pushing the horizon in search of new technology to improve the efficiency and accuracy of how we explore and address pollution in our watershed. GIS, or geographic information system, mapping allows us to visualize data that tell a story – visualizing data on maps makes information more easily digestible.
GIS maps not only help us communicate with our community, but with elected officials, too. We present maps to elected officials as motivation to take action, support a new bill or make a call to a state regulatory agency grounded in science-based data in their jurisdiction. GIS maps are effective tools that support our litigation work and improve community education.
Mapping PFAS Risks to the Public
In particular, we have used GIS mapping to communicate PFAS risks to the public. Upper Potomac Riverkeeper, Brent Walls made this map showcasing active biosolid permit sites in Maryland. Aside from being a communication tool showing potential PFAS risk, this map demonstrates how underserved communities are disproportionately impacted by this health threat.
