06.09.23 - Geo-Tracking the Unseen Enemy: PFAS Contamination and the Rise of GIS Solutions

Unlocking the Power of GIS in Tackling PFAS Contamination: A Workflow Breakdown 
 
The fight against per- and poly-fluoroalkyl substances (PFAS), those persistent "forever chemicals," has found a powerful ally in Geographic Information Systems (GIS). These molecules are used to manufacture everyday objects, from Teflon frying pans to dental floss. Let's dive into how Wisconsin Department of Natural Resources (DNR) is harnessing GIS tools and workflow to combat this global environmental challenge.
 
Mapping the Battlefront: Wisconsin DNR has orchestrated an intricate GIS-based workflow to map the prevalence of PFAS across the state. This isn't just about pretty maps; it's about precision. The GIS system provides crucial data to identify contamination hotspots and prioritize remediation efforts.
 
A Global Trend: GIS isn't exclusive to Wisconsin—it's a global trend. Countries worldwide are employing GIS technology to sample water and chart PFAS concentrations. This geographical insight guides effective decision-making.
 
Wisconsin's GIS Approach: Spearheaded by Melanie Johnson and Jesse Papez, Wisconsin DNR developed the Wisconsin PFAS Interactive Data Viewer—a game-changer. This tool visualizes PFAS occurrences across the state, making complex data accessible and actionable.
 
Collaboration Beyond Borders: GIS is the universal language of environmental protection. Wisconsin DNR seamlessly shares data with neighboring states, facilitating collaborative research on PFAS contamination in wildlife and ecosystems. It's a united front against a shared threat.
 
Breaking the PFAS Cycle: Continuous data collection and mapping are the keys to breaking free from the cycle of PFAS contamination. GIS is at the forefront, enabling us to monitor, act, and protect our environment.
 
The battle against contamination is a global mission, and GIS is the tactical backbone. It empowers us to make informed decisions, foster collaboration, and safeguard our precious natural resources. As we evolve our strategies, GIS will continue to be our guiding star. 
STDL is now conducting a project using GIS techniques to monitor soil pollution in collaboration with the Etat de Fribourg, utilizing LiDAR point cloud and aerial images including the NIR band. Following us for further updates and potential collaboration.
